@@naakatube its not that simple. If it was this wouldn't be a debate. the detectors are placed way after the slits as with the delayed choice experiment/quantum eraser experiments which means they are detected significantly after they have already passed through the slit. Turning on the detection "retroactively" reverts the pattern to a particle pattern and turning it off gives you the interference pattern.

Here's an easy way to understand it. The houses that you see on the side of the road that you drive by in your car. There is nobody ins those houses until You jump out of the car run over to the house. Your brain make what in front of you. There's nobody in those houses while you are in the car insde the house. There is just probability waves. Once you see who in in the house you manafest. them from thewave onto an object. When you jump out of your car and run over to the houses you're actually creating the person that's come out that's in the house. Does a tree falls in the woods and make a noise. No. Not until you're see or hear it in forest it doesnot exti unil you see it . Your Consciousness collapse the wave form function and make the object real. You collapse the waveform function and make the object real . reality. the particles Into existence and now they become a permanent object.

Joe Scott Your video is one of the best I've seen for a laymen like myself. Comprehensive, covering the most major areas, yet simple enough for me to understand. Thanks.
I have a theory, concerning "observation wave collapse"... The field emitted by the test equipment induced union among the photons. Photons are, by nature, charged particles... as such, they are sensitive to any fields within their environment and must react to them.
Yucky man, simulation theory. The light waveform exists to save processing power. When not observed an approximation is sufficient, when observed all the maths get done and a specific location is determined. Kind of like textures changing quality in a video game when an object moves from the background to the foreground. The truly terrible part is because shortcuts are being used while rendering our existence, we can be moderately certain we are not on a high end computer in a laboratory running a perfect simulation, but on some kid's playstation where you need a few tricks and shortcuts to keep things running smoothly. Our lives are some fourth dimensional baby's Fornite. What terrible DLC comes next?

One more thing, the most mind boggling part of the experiment was left out of this video... where a detection mechanism was placed directly AFTER the slit. The waveforms collapsed BEFORE the slit indicating that beyond the slit the particles “knew” they were “going to be observed” and therefore “should act like particles”.
No. What's happening is the virtual reality rendering engine does not render what no one is looking at or track the movement of every particle in the universe. That is a huge waste of computational resources... so it cheats and uses probability distributions.. it saves more than 99% computational resources that way.. It works on the large scale. Open a room door at your house and probability distribution collapses and you see what's likely.. more dust on surfaces in line with possibility.. This is a simulation.. you are a consciousness floating in a dark void receiving a data stream representing your avatar. Part of a larger source. Welcome to entity school. Your purpose here is to gain experience, create information, lower your entropy as a being, help the larger source evolve..

@@mysticjedi6730 maybe, maybe not. Being in a simulation certainly doesn't explain everything away if anything it brings up many more questions like why did someone start the simulation and did whoever start our simulation also come from a simulated world? What happens to an individual conscience when it dies in the simulation? To say "we're in a simulation get over it" is the same amount of ignorance as someone saying "God made it so get over it" us being in a simulation really doesn't change much of anything we still have to goto work tomorrow and in terms of the universe we already knew about our insignificance, the only thing significant we can change is in our own lives with our loved ones

I'm five years late but there seems to still be conversation here. My favorite interpretation of these results is not that the act of observation collapses the wave function, but that when we measure it, it becomes entangled in its environment. This gets into the Everettian interpretation of quantum mechanics, and removes the collapsing of the wave function as a piece of QM. Instead, all possible outcomes really exist in different branches of the wave function, and by detecting it at the slit, you've limited the possible outcomes of its position because you are also entangled with the environment that the particle becomes entangled with. Not only does Everettian QM provide an explanation for the double slit experiment, it provides an explanation for the Delayed Choice and Quantum Eraser variations of the the double slit experiment. Whats more is, it doesn't just provide a framework that makes these outcomes make sense, it is the expected behavior. But, we have to come to grips with the mind boggling strangeness of the idea that every possible reality that ever could have happened from the beginning of the universe up til now and beyond all exists in a real quantum superposition. There's a branches where i've died of cancer, branches where the nuclear bomb at hiroshima didn't fire, a branches where our sun and solar system never formed; but we will never access them. Sean Carroll goes further in his book Something Deeply Hidden, where he then uses Everettian QM to derive spacetime from entanglement, and gravity as an emergent property of entangled particles; eliminating the need to quantize gravity, something we have been trying to do for nearly a century with no success. It allows QM and GR to play nice.
@@Sharperthanu1 "Question:Why isn't the wave function entangled with its environment BEFORE we measure it?" In a way that's what I want to know. More specifically, what events make the wave function collapse ? I mean, even in the vacuum of space there's still something, there is no (truly) empty space. In our world there's also air, and lots of light (these experiments are not done in the dark, right ?). So why isn't the wave function collapsing all the time ?
First of all, there is no collapse of the wave function. The wave function is not a physical object. Secondly, entanglement is a reversible process. Measurement is, by definition, irreversible. More precisely, measurement is irreversible energy transfer and if you do a measurement on a quantum system, then you have irreversibly destroyed the system.
When I first heard about it actually changing when observed my mind was blown. I literally said out loud "there is NO WAY that happens!" It just seems unbelievable and surreal.
The "which way detector" is an active detector. Human eyes are passive detectors. The which way detector actually alters one slit's wave pattern such that it does not interfere with the other slit. Hence no interference is interpeted as particle behavior. Observation itself has nothing to do with the change. Some have speculated that this experiment somehow proves consciousness extends beyond the mind.
I agree. I believe the detector is altering the results. Nothing more nothing less. Because the behavior is consistent it's obviously not 'a flaw in the matrix'@@FreeSkeptic
There is no need to introduce “consciousness” into the description. Once any information is gleaned about the electron, it’s fundamentally changed. It takes a energy to retrieve information from the probability wave function, and that inspection (be it light, or a detector) changes the probability from anywhere to somewhere. All “which way” data that you can have will always require you to alter the probability. The only way you can ever have an interference pattern is if you have no information about the electron, which would keep it traveling through both slits and interfering on the other side of the slits. Collapse anywhere, and the wave becomes localized.
THANK YOU. It's extremely frustrating hearing people say things like, "when you LOOK at it," as if when a human scientist's eyeballs are "watching" the experiment. It's because the detector ITSELF interferes with the wave. Misunderstanding these opens the door to so much woo and pseudoscience.
Here is the problem with what you are saying. It is true that making an observation (measurement) has some affect (even if very minute) on the photon, but how does it know if someone is taking a measurement (watching) , or if it is just passing by something else that just happens to be there like say a gravitational force, or some other particle, or some small piece of matter?
@@danricci7855 Reality is always watching, the information is censored, so we cannot know. Even when the measurement occurs after the event , it changes itself backward in time. The common denominator is knowledge, if we gain knowledge of the system it self censures.
@@gerardjones7881 Yes it appears that it could be that the photon knows what the future is and adjusts accordingly, but if that were true then that would be deterministic, whereas quantum data strongly shows randomness, not determinism.
Terribly explained, when the particle is "observed" it's not a conscience observation, these things are way to small to observe through any microscope so you must bounce another particle with a known velocity off the photon and measure how that changed your original particle velocity. Through this you can determine which slit the photon went through. And the act of doing this collapses the wave state into a particle state. In physics the term observation means to interact with the system in some way. not necessarily see it. (Im not a physicist so my explanation is awful but not filled with fake info like the vid)
Towards the end, at 5:54, you mentioned "How does conscious observation change the nature of matter?". The fact is conscious observation does not collapse the wave function, measurement does. There is a distinct difference between the two. Great video, thanks for posting.
You're correct. I would like to know what the "measurement" procedure is. A tape with inches and feet? What is the process scientists use to "measure" light waves/particles?
Good point. But, the measurement is a record of something in a collapsed state because it needs to be. The information is preserved/a record for eventual conscious observation. A delayed, conscious observation is still a conscious observation. The particles can't be tricked. I've always felt this behavior, and how entangled particles behave, to ultimately be connected.
maybe as thw water in the tank experiment. the light is in fact a particle that avels in waves, and thats it. the observation with electrical devices afect them
@@elpelagabriel1755 or the light is always the wave which can be observed only when it collapsed to a point-object state. the measurement (interaction) collapses the wave (making it concentrated in space coordinates)
Double slit experiments kinda support the simulation theory in such a way that our reality/universe blinks in of existence only when needed or when someone's looking. Very similar to computer games where graphics are being renderred only when the character has to interact with the environment which needs to be renderred. What a great and clever way to save up on processing and computing resources :) Just my 2 cents

Nope, because you could just set it up, walk away, and then come back later to see the results. Also, as was stated a few times in the vid, these experients have been run many times, in many different ways, and the results are always the same. Also, the way the experiments are set up are just for lab conditions, for ease of observation - they happen naturally in nature all the time, and is observable and predictable.
There seem to be two schools of thought. 1) I've heard that the "observation process" collapses the wave function. By this people are thinking that a conscious observer (or something special about the organic matter making observations) is influential on matter being observed. I can see why this is attractive as we are organisms made up of the very particles in observation. As we see a great deal of connection in all phenomena throughout the course of our daily lives... certainly we'd like to see this same connection at more fundamental levels too. But then there is 2) And from this I've heard that it's the "MEASURING PROCESS" that collapses the wave function. And I need to be very clear here that I'm talking about MEASUREMENT and not conscious observation. This to me suggest that the matter we are dealing with is so small in magnification that the properties with which we extract measurement are inaccessible (kind of like a truck scale weighing a piece of dust). So my questions from this video and these two different schools of thought is.... What is really collapsing the wave function? Is it consciousness or measurement? I don't think these two things are the same. There must be more conclusive data and experimentation with which we can affirmatively rule out or tie in consciousness. If it's measurement... and this is creating the major difference in the double slit experiment... what are the fundamental properties of measurement? A measuring device and its process must be in some way composed of the very matter being measured. Another way to say this might be to say...."One hand can shake another... but a single hand cannot experience the 'hand shake' by itself.' We're approaching a point where matter cannot deliver an understanding of itself now matter how it's re-assembled for the purposes of the question. Even Allan Watts the philosopher said too. "The Godhead cannot be the object of its own knowledge".... fire cannot burn itself, the tongue cannot taste itself... teeth cannot chew themselves... etc etc. At the end of the day..... Matter might not be able to explain itself.. (or Matter to itself). I have no Physics background whatsoever.....but this stuff does seem quite important and has contributed to our lives greatly... therefore I do try to understand. :)
Indeed the measurements are not passive. This has the same dilemma as our attempts to study signs of life on Mars: To analyze the samples that our rovers collect, we INCINERATE the samples. Even if Curiosity collected a bunch of Martian microbes, we still wouldn't "observe" that as anything other that traces of organic compounds. Because we incinerated the microbes to "observe" them.
@@Maxgamer-fd7hv Just because you want to understand the universe doesn't mean you're equipped to. We did not evolve to understand it, just to survive it. There could be all kinds of things we will never be able to detect or comprehend because it was irrelevant to life on Earth.
I found the Kubrick variation to be the best. He used a pair of entangled party girls to demonstrate the double slit experiment in Eyes Wide Shut. I took a hard look at the data and came away satisfied. Perhaps if I had kept my eyes shut, my waveform wouldn't have collapsed into a load of messy particles. I will power my photon gun at a higher frequency, and attempt to extend the waveform indefinitely, a sort of tantric experiment, te he! Let's hope that i don't blow it by peeking too soon.
A reply to your double slit experiment! Question the observer effect, that changes the results! What or who is the observer? That answer seems to elude everyone in a scientific field!! It annoys me! Who is the observer is the key to double slit experiment. When asked who are you, I’ll give my name, my work, my family, etc etc etc! But really who am I? Let’s compare the heart and the brain. Dr’s can remove a patients heart and reconnect it to a pump to keep the patient alive! We can’t do that with the brain, so it has to be a thought experiment! Let’s imagine that such a procedure could be preformed! Now with the brain removed and you ask the patient “where is the me that has a brain?) . “I” “Me” most people believe that they have a brain, as if there were a separate entity that possess a brain! There’s the rub! When I say the words “I or me” there is a mis-perception” , that there is a tangible entity “me” or “I” that has a brain separate, apart, that “I” possess!!! The “I” that believes that “I” exist, is the error! What the so called “me” actually is, is in the make up of the brain itself! The neural network, the synapsis and receptors, all the connections, the memories, the upbringing, the experiences, the programming of society! All of that creates the (mis) perception that I am a tangible entity that I call me! That gives the “i” the observer in the “Double Slit Experiment” results! The belief that “I” am objective entity or observer exist! The belief that “I” can observe objectively is false!!! The belief that I am a separate entity observing the experiment has an effect on the experiment!!!!! A belief in an “I am” separate from the experiment creates the conflicting results! Like trying to objectively observe the laws of nature, when I am a part and product of those very laws! It’s impossible! To be objective, you would have to be separate from those laws! With the revelation that there is no tangible “I”, dare I say that “I” don’t exist, well not as I believe I exist! With the (mis) perception that I am, a tangible separate from; the universe, the Double Slit Experiment cannot be understood! “I” life itself, this seemingly different form was labeled with a name Randy! Once upon a time I believed that I had a brain a mind that is mine! Now I realize (if only intellectually) that I don’t possess a brain/mind, But am a product of the brain! A programmed mind/brain, programmed by others that believe that they possess a brain! Ignorance begets ignorance! Ignorance = lack of knowledge of the truth! And if you don’t know the truth, you can never teach the truth! J. Krishnamurti said, “The Observer is the Observed” ! My last comment finally, I kinda believe that little song, Row row row your boat ____ _____ ..... Life is but a dream! Oh by the way, a nightmare is also a dream!!! Gently down the stream, merrily merrily Were not separate, we’re all of the one Life, Belief in separation breads fear! The Slit, the double Slit! I’m not religious but a book said “know the truth, and the truth will make you free”! Know it beyond the intellect, see the fact! Don’t believe in anything! Believe is not knowing!!! Tho many many many believe in believing, convincing themselves that there believe is the truth! Belief is not fact!!! These believe in this, and those belief in that! Now we’ll have WARS and every form of ignorance will be spread as truth! Oh our pain, so much pain! If the true understanding of “The Double Slit Experiment “ we’re realized! Who is the observer? Penetrate the layers of the question. “WHO AM I” Am I just my name, am I just my job, am I my stomach, my bank account? Penetrate deeper to know the truth! WHO AM I? Really, don’t just believe, dig for the truth!
So could we in theory communicate through time with this? If the observer choses to observe it will affect the outcome so by chosing and not chosing you could send a string of 1 and 0 (garbled by probability so you would have to do it a lot of the time so the recipient of the message could see the most likely message). And what Joe said means that this works back in time too so it would effectivley be instant communication even though one party will talk a lot later. But the downtime between messages would be near zero.
Sadly no because the person on the other end of the quantum entangle communicator collapses the wave function when they try to observe the particle/photon and thus have no idea if it was collapsed by your detector or theirs. All of them will be particles without the wave function so all would be ones or zeros in your scenario I think.
@@clearmist1 let's presume future you will talk to present me 2 months from now, so now we both come up with a code that future you will be using to send messages back to present me. Easy!

@Alex DelRio No, we would have proof that the wave function interacted with "something" physical and collapsed. Consciousness really has nothing to do with collapsing wave functions. In the double slit experiment, you can run it without a detector and see the wave pattern. You can then run the experiment with detectors that tell you which slit the particle/wave went through and you will have the particle pattern. You don't have to be in the room to consciously observe the detector. You can leave the room an go have a smoke and come back and the wave functions will still be collapsed.

1:58 Wrong! All the slit experiments show that lights is waves, NEVER particles, the same is true for all frequencies of electromagnetic radiation. So-called 'photons' do not exist, there is no such things as light particles and there is no such thing as "wave/particle duality". Physicists had developed a system for analyzing waves, so they applied their wave-system to matter by treating matter as waves, then followed the converse proposition by treating waves as matter. The wave/particle duality is merely the nonsense of misapplied system analysis. Electromagnetic radiation (EMR) is waves at all frequencies, never particles. Every experiment shows light is waves, there are no EMR particles, there is no duality. What they call "single photons" is a high frequency interrupter relay transmitter switch used to produce single separate individual wavelengths, like this ~ ~ ~ ~ ~ not "photon particles". Continuous waves produce interference patterns and intermittent separate single waves also produce interference but at a slower rate/intensity because of the gaps between waves. The interference is the proof that light is waves at all frequencies, never particles. "Probability waves" only exist in researchers imagination, that's why nobody (including de Broglie) could design an experiment which shows light is particles. The photoelectric effect is easily explained by blue light having the right frequency of positive/negative magnetic induction (alternating push/pull) to magnetically agitate a negatively charged election out of it's shell orbit, that's why the photoelectric effect does not work at higher or lower frequencies - nothing to do with "particles". Did you believe red light was waves but blue light magically manifested 'particles' which disappeared again at higher frequencies. Electromagnetic Radiation (EMR) is waves at all frequencies, all the experiments show light is waves, there is no experiment which shows light is 'particles'. 4:00 The "photon detector" is an imaginary mathematical idea, not a real device. It is impossible to passively tag a wave (or a particle if you prefer) with an identity as it passes through the slit, the only way to detect a wave is to put physical matter in the path which consumes the wave energy by absorption so obviously nothing would come out of that slit. It's the same wave which goes through both slits and causes interference from two separate slit sources on the other side. The interference experiments do not have any detector because that would block the wave and cancel the interference, that's why NONE of the interference demonstrations have detectors. There are hundreds of videos showing the actual double slit interference but none showing the actual wave function collapse as the interference pattern disappears into observed "particles" because it's only a thought-experiment. Quantum electrodynamics textbooks give a summary of the discussions between Bohr and Einstein in which they each propose a variety of impossible imaginary "detectors". They were just talking, the 'detector' was just an idea. Physics had a well-developed analysis of waves, so as a thought experiment they started treating matter as waves, later they reversed the thought experiment and started treating waves as matter, the self-induced paradox of the two thought experiments created wave particle duality and 'spin' only exists in the minds of believers, not in reality. Schrodinger published his cat in a box thought experiment only to demonstrate the absurdity of the wave/particle duality idea, Schrodinger was later very surprised to see his absurd cat in a box story being used to demonstrate the true nature of state vector collapse wave/particle duality. Relativity and Quantum Electrodynamics are thought experiments, that's why cosmology and QM are a cult-like belief system with a priesthood guarding their made-up doctrine by excommunicating doubters, for example, it is impossible to have academic career in physics if you say there is no proof that black holes exist. There are some places in the universe which seem to have more gravity than expected and some of these places seem to have more gamma radiation than expected, that's all we know about "blackholes", everything else is speculation, but if you publicly say this you become an outcast without any academic employment prospects. Go and search for actual experimental evidence of wave/particle duality and you won't find it, because it does not exist. Electromagnetic Radiation (EMR) is waves at all frequencies, never particles. You must have suspected this surely?
Yes I like that LOL It is not just looking! Even in the two slit experiment it is turning on an electronic detector the collapses the wavefunction Ψ. This video explains the experiment: ruclips.net/video/MTDwUeIolAQ/видео.html
it's really simple... the programmer used a simple if-then-else statement to keep semi-intelligent simulator subjects (us) from learning the truth. if TEST = unobserved double slit; then PrintLn ( interference pattern); else PrintLn (particle pattern);
There is a version of this experiment where detectors on the slit determine which one the photon passed through, and there are two observers. One has the detector information and the other doesn't and both patterns emerge! So two observers can see very different versions of reality.
It gets weirder still. It isn't just photons that don't this but electrons and atoms too. I read that someone is trying to do this with a molecule the size of a small virus. If proteins can behave this way then what does that mean for biology?
I know I'm late to this, but you always have to remember one thing. Photons are MASSLESS energy particles (or waves......), while anything else is such as electrons and atoms DO have mass. So correct me if I am wrong, but I don't believe that proteins can act like this. (I'm only 12... don't judge me please xD)
Everything can act like a wave including molecules (proteins), it's just that the wavelength is inversely proportional to mass so it becomes undetectable at some point (the size of a very large molecule).
I know this is an older video and you may not check the comments anymore, but I've always wondered what if a third slit is added? Is there any change in the results?
if photons travel at the speed of light then from their perspective time has stopped. a photon experiences the entirety of its existence simultaneously. so it doesn't seem so bizarre that it would "know" the future as it is experiencing that at the same time as our present; as one stationary line between where it started and where it ended. we measure one slice of that line and call it a photon. it's only from our perspective that it would seem odd that cause and effect are backwards. i know this doesn't really explain exactly how the photon "knows" to change the result we see, but it must be something to do with forcing a particular future to occur by knowing in advance which slot the photon went through. we can't know that information without it reducing the possible outcomes and from the photon's perspective that outcome is already happening as one static picture.
I replied with almost the same answer, before i read your comment, thumbs up! another thought along these lines, If the universe is expanding at an accelerating rate, would there be inertia affecting things? maybe as what we call gravity? may just be the inertial effect.
@@tomf3150 yes actually; that might be part of the answer. Some have said that subatomic particles don't seem to experience entropy like molecules do, and time is just a measure of the entropy of a system to some people, so... Yeah, totally
I've heard this argument before. But it is incorrect. Consciousness is absolutely required to collapse the wave function. Not only that but it must be your own consciousness. Every measuring device, and every other observer will necessarily become integrated with the wave function, including much of your own body and brain, until your own personal consciousness requires its collapse. It makes no sense to imagine a wave function collapsing for anything else. If you think it does, please explain what physical process can cause a wave function collapse.
entaglement in a quantum system (IE measurement) is what alters the wave. It's not consciousness. It's measurement. If you want to consider a 'computer' conscious. Ok.
Read about Schrodinger's cat thought experiment. It explains how a cat can be both dead and alive at the same time. How is that possible? Because from the point of view of the external observer, the wave function did not yet collapse, because the contents of the box was not yet observed. But surely the cat would qualify as a measuring device, and yet the wave function does not collapse. Instead the cat becomes integrated with the wave function. And so would any conceivable measuring device. Also imagine that Schrodinger's cat is inside Box A, and Box A and observer A is inside Box B. If observer A looks inside Box A, then observer A becomes integrated with the wave function contained in Box B. Only an observer outside Box B can collapse that wave function. If you follow this to its logical conclusion, it means that the only consciousness that can actually collapse the wave function from your point of view is your own personal consciousness.
For every action there is a reaction. Why would people expect the action of observing be any different? Legitimate question as I am struggling to get my head round this.
Your confusion stems from you making a false equivalence. "For every action there is a reaction" is Newtonian physics, and it realates only to classical mechanics, in particular; mass and force. The 'action' in Newton's case was regarding the application of a force, not the 'action' of an observation. That's why people didn't expect the mere observation of a natural occuring phenomenon to have any effect on the experiment, because the action of observation didn't input any mechanical force into the proceedings, you see? That it did in the double-slit experiments is what blew the lid off Newtonian physics (well, that and Einstein's Theories of Relativity) and ushered in Quantum Physics.
I would like you to do a whole video on the delayed choice quantum eraser. Why? Because nobody has made a good video to explain it as far as i know and you seem to have an ability to explain things really well.
So I have been watching hours and hours of your videos now. It's fun to see the changing background from these old ones to the new ones, plus I see the "You See Cam" changed to the "Tangent Cam" when about did that changeover happen?
Let's not forget about the complexity of the brain. I would include the brain and the eyeballs as variables. But what do I know? I'm just a stupid fisherman
I do a lot of 3D modeling for architectural visualization and have to render images at the end. One way to cut on render time is to pre-calculate light bouncing in 3D space in the scene and save it as a file the reuse it for the final render.

Albeit three years late, I will throw in my 'particle'. When we initiate an electrical beam (i.e. turn on a light), we actually give excitation to the 'field', where the entanglement begins... causing the particles (photons) to vibrate (oscillate, i.e. wave).
Since the particles are in superposition, they are "already in both places", just not yet vibrating at the other end because entanglement hasn't occurred on that other end. The excitation would travel at 186,000 miles per second. In this way, light could be expressed as a wave AND a particle in the same model. Light is a particle, being vibrated (oscillated) in superposition in a field that is expressed as a wave at the speed of entanglement (not the speed of light).
@@mikeock2087 it's based on Quantum Electro Dynamics, QED, developed by the great Richard Feynman. He was quite disappointed to realize it comes with all the same baggage as, and explanatory problems of, treating light like a wave. Instead of the Ultraviolet Catastrophe, it creates the Vacuum Catastrophe. While some credit him with 'explaining' the DS experiments and even the phenomenon of Iridescence; he himself was well aware it didn't count as an Explanation of either phenomenon. Next theory...
Um.. if the observed data was encoded as the product of 2 multidigit (billion digit) primes, not individually observed, then if the wave collapsed this suggests that in future quantum computers could find the individual primes, thus giving comfort to those trying to develop quantum computers... or if the wave does not collapse - because it remains always computationally impossible to find the 2 primes - not.
I rewatched this, again. (I have watched virtually watched every one of your videos, kudos.) One thing you said may be pure genius. "Non-locality and non-temporality". Does this suggest something? Consider special relativity. Time and space are inseparable and are relative. Sorry to reDO YOUR BRAIN IN. But it strongly suggests that our observation of reality is, well, strongly relative. We can't explain our observations because we are the observer, not the participants. Just a thought. Maybe there is a unified theory if you quantise special relativity. (Visualise Einstein superpositioning in his grave). Worthy of a video?
In my unprofessional, uneducated layperson understanding of it, when you "observe" it, you are using detectors. In order to detect something, you have to interact with it. It's that interaction (however it is being achieved, I don't know how the detectors do the job) that causes the waveform to collapse. It's not that the particle/wave senses your gaze or your consciousness, it's that the detector has disturbed it.
The Detector doesn't interact with the particles like you think, it just observes them and inside the detector and its software, calculations are made, just like a camera doesn't interact with you when it snaps your picture. Someone may be snapping your photo from across the yard, you wouldn't know it though. Somehow the light knows someone is hiding in the bushes, snapping their picture! This is my very slightly educated understanding anyway :-)
...so we have known about this for 2 or three hundred years and we are still no nearer an answer, in fact it keeps on getting worse? .............were all doomed!!!!
Can you explain how two planes crashing into two buildings could make a third building collapse in the exact same way the first two buildings collapsed. All three buildings collapsed at free fall speed, encountering no resistance. I have asked and searched for the answer to this question for 20 years. No one can even offer a theory of how it would be possible. Can you?
'Observing' a photon means detecting the photon as it moves past the observer. How do we do that? Well presumably we measure the change in an electro-magnetic field as the photon moves through the field. Huh? Let's assume the photon is a super-tiny particle of light or a super tiny wave - whatever! My electro-magnetic detector is a device which produces an electro-magnetic field and it records changes in the field caused by some other field which interacts with it. That 'some other field' is the photon we are trying to observe. So the only way we can detect the photon is to hit it with another photon.... Yeah, I know this is getting probability and certainty all mixed up... but surely this has something to do with it?
This is the a quirk of how time works. For the photon, no time passes from its creation to its destination. But since we experience time differently. The reason the photon changes is because, from its perspective we are going back in time to change its timeline. Essentially it has already done what we are seeing it do. Therefore when we change something, to it, we are time traveling. So as I said, simply a quirk of time, and essentially the none existence of time at lightspeed. This is also why if you move close to lightspeed, you experience time slower than other people, essentially traveling forward in time in relation to everyone else. If you could move at lightspeed (without hitting anything) you would instantly teleport to the end of the universe. Both the end of time and the literal edge of the universe. To teleport, just move at lightspeed. This is actually the basis of the "relative" part of general relativity. So to warp everything. To the "big bang" the universe has already ended. To that blob that went "bang", the blob has already expanded to the end of the universe, while to us it's only the beginning and still expanding.
@@shirleymental4189 I wouldn't take any real credit. I'm sure Einstein probably wrote something just like that, the guy was very smart. I actually heard the photon thing from Joe Scott on his video about, why is light so slow. I don't really have any math to back anything up. I just "put 2 & 2 together" and got that. I don't honestly have any way to test it. I just used logic and reason to make sense of things that baffle so many scientists. And I'd assume others have come to the same conclusion and the thing that baffles them is trying to find the math proves that hypothesis. And math doesn't like time travel, since time travel brakes causation. Causation is the basis of all math. PS: I have other observations that talk about quantum fields and how the atom is probably the long sought Graviton.
But since time wouldn't pass for the photon (or whoever was traveling at lightspeed), meaning it would take an infinite amount of time from the traveller's perspective, you would be stuck traveling forever before you got anywhere from your perspective.
@@aaroncurtis8545 That's exactly what's been done in all of the experiments. Looking at light doesn't make the wavefunction collapse. Measuring it does.
@@4Leka I think you think you're telling me something I don't understand... But I'm trying to tell y'all that there's something deeper there that you're not understanding. It's logically akin to people not understanding the difference between 'saying what you mean and meaning what you say' in Alice in Wonderland. But truly, you're missing something that the founders of QM saw in this process which has never been resolved and is still referred to as 'The Measurement Problem'. There's a Reason the word Observation was chosen, as opposed to the word Measurement, and you're not getting it.
You can't passively observe subatomic particles, to measure them you must hit electrons with photons or some other means, an active process, which means it's impossible to observe their behavior without interfering with them and changing their behavior. They don't behave differently because they know they're being watched... that's woo woo.
Thank you so much. I’ve been obsessed with quantum mechanics videos for the past two years and non of the videos I’ve watch have defined what measurement or observance is until yours.
The "which way detector" is an active detector. Human eyes are passive detectors. The which way detector actually alters one slit's wave pattern such that it does not interfere with the other slit. Hence no interference is interpeted as particle behavior. Observation itself has nothing to do with the change. Some have speculated that this experiment somehow proves consciousness extends beyond the mind.
I think why they say “observed” they mean interacted with in same way. Eg. in order to detect a wave/particle you have to interact with it. My head hurts....
3:43 "this experiment has been replicated..." I cannot find any video on RUclips, or anywhere else on the internet showing this experiment actually being replicated, nor do I understand how you would replicate the experiment. I have seen the interference pattern in physics class in highschool, which explains that light acts as a wave, but I do not remember ever seeing the "switch" from when the light acting as a wave when observed/unobserved, to acting as a particle otherwise. Has anybody actually seen what this experiment involves? I mean, it's almost like a contradiction to say that if unobserved it acts one way and when observed it switches. How do you know how it behaved when it was unobserved.... if it was indeed "unobserved"?!
When we say unobserved we mean not using a detector to see which slit each photon went through. What you did in class was unobserved, as in you only viewed the projection
I'm guessing the reason observation changes the effects is because the quantum world is tiny as fuck. So any input of energy from a macroscopic scale is going to be like igniting a nuke to quantum particles, atoms, photons, etc.
It is not just looking! Even in the two slit experiment it is turning on an electronic detector the collapses the wavefunction Ψ. This video explains the experiment: ruclips.net/video/MTDwUeIolAQ/видео.html

There are no dualities in nature. Light is neither a wave nor a particle. Light is a coaxial circuit made up of both longitudinal and resultant transverse electro magnetic disturbances in the ether. Once we wrongfully believed the ether did not exist, every phenomena had to be explained using bumping particles. The fact is that everything is fields and fields are not particles. Light does not travel but is merely a propagation of a disturbance in the ether. Quantum theory is based on a misunderstanding and will one day face its deserved demise. Joe, you presented the current wrongheaded issue well however.
Joe has (I believe) advanced in his understanding of the double slit experiment since he made this video. His misunderstanding is well described and countered in other comments, but, basically, consciousness and his emphasis on it, is a misleading factor in this experiment.
l don't believe you should think of this as your typical "wave" but rather as a probability wave... the particle can show up anywhere in the interference pattern but will only create the interference pattern after enough particle have gone through the slit to be statistically significant. This is the basic mystery... what does nature know or care about probability waves?
I've always been amazed at how the universe has such strange properties as this (episode) and quantum entanglement yet in no way is it possible to send information backwards in time. For example I'm sure the very last study in this ep - to affect a photon in flight by changing the end condition of its path - could not be used to send a laser communication around the world and provide the effect of negative latency when read at the mid point by affecting the light not when sent but when returned.
In relativity, from the perspective of light itself, time around it has completely stopped and the light exists in all places at once…this must be some part of the explanation of the delayed choice experiment….as something approaches the speed of light time slows down, at the speed of light time stops, putting the light or object in all places at once, because there is no time for something traveling at light speed….so if there’s no time movement at all as it travels through space, there is no before or after, but as an enthusiast I’ve never heard this idea echoed before
+Congruesome: When you think about it, or bodies including the brains we use to comprehend the universe are made of the same stuff as is being observed/measured. We ARE a part of the universe. We are, ourselves, part of the observation.
I like this "Broseph" moniker for our friend Joe. I see it as an amalgamation of Josephus (famous Jewish historian) and The Dude, from the The Big Lebowski. The Broseph abides.
Perhaps all matter and particles are merely the constructive interference of the very universe itself. This would explain why matter appears to not be absolutely definite at some points, and why events in the future might affect it in the past.
😂 feels like we are living in some sort of computer simulation. If we observe something there is no need for the wave to continue to calculate what the future state would be. Or if we know that in the future we will have a change no need to calculate the wave before this. My brain is melting.
What if these quantum particles are ALWAYS a particle and a wave at the same time and these experiments are inadvertently filtering for one answer or the other? How are they "observing" which slit it goes through? There must be some interaction with the particle along its path for this to be possible.
Maybe the device we use to measure which slit it goes through robs the particle if it's "waviness". Maybe those waves are being cancelled before it enters.
I've never seen any video of this aspect of the experiment - the measurement of which slit it goes through - being conducted. I'm not sure if the technology exists to measure where a single particle will go with out stopping it… but the fact that the detector is only placed on one slit - the assumption being that if the detector does not register, that the particle must have gone through the other slit or collided with the frame - does, logically, accommodate for the possibility of the observation interfering with the experiment. If this experiment has actually been conducted with such a detector in place, and this phenomenon has indeed been produced then, yes, it is really weird. So, I've answered my own question.
the double slit experiment has always been the most interesting scientific experiment ever conducted to me and I love listening to the theories people come up with in an attempt to explain the weirdness of it and the possible implications

i think it can be explained by our limit as the observer. We see the world but don't see what we aren't capable of, aka 4d, and then 5d, which creates interactions between light reality time and space that we cannot concieve with sight alone but we can imagine it only by accepting that we cannot
That skit of hitting your nose, well 6 years ago I got in bed around 10 and suddenly the back of my head felt like it was hit and started hurting so bad I threw up and got so sick. lasted a few minutes. didnt hit my head or anything.. Then the next night same time going to bed tried scooting back against the head board to sit up in bed and hit that spot against the wooden head board and felt the same pain for the same amount of time. I literally hit myself so hard i felt it 24 hours earlier. There are things in this world that dont make sense (also my wife was there both nights and says my memory is right just in case someone was wondering if I hit my head so hard it messed with my brain and made me think I felt it the day before)
The answer is that the experiment did not, and never has, “shot” particles through the slits. It’s only and always a wave, which is not a thing - a “wave” is a field perturbation, nothing more. The act of “observing”, ie interacting with the wave with matter, is what messes up the wave and causes the lack of an interference pattern. When they stop using matter to interact with the wave (“observing”), it goes back to the normal interference pattern. There is no “duality”, and nothing weird going on here. The only thing that’s weird is scientists belief that the universe behaves in inexplicable ways.
It is not just looking! Even in the two slit experiment it is turning on an electronic detector the collapses the wavefunction Ψ. This video explains the experiment: ruclips.net/video/MTDwUeIolAQ/видео.html
Gravity waves are a fairly recent twist on the situation right? I hope this will explain some things that just sound like they used the process of elimination without knowing all the possibilitys.
+crowtep1 yeah, I could be talking out of my ass because I'm speculating that particle positions are not only quantized when in atomic orbits but in all dimensions (however many there are). Since gravity waves bend/stretch time and space, the quantized positioning would be further apart toward the peaks and troughs of waves. In the "observer" experiment the particles lose some energy due to the measuring process and thus skip across fewer quantized positions making the "double slit "shadow".
+believerornot do we know how much g waves will effect positioning yet ( probably right in front of my nose, sorry it's late). Might there be a gravitational effect of observation/ measurement that would effect the energy in the results?
crowtep1 well I'm speculating that gravity and gravitational waves do have an effect. I'd like to see the double slit experiment performed in the space station.
Joe, I tried to tell you "Existence and CONCIOUSNESS are Synonymous!" We've been anylizing the universe from the wrong perspective. We assume that we (lifeforms) are the only perceiveor! Not necessarily true. All lifeforms are expression's of, and extensions for, universal conciousness...
So here's my thought. Perhaps the double split experiment during observation gives credence to the hologram, OR the matrix theory. As if it was a program fail safe in case we (the observer) discovered this. And as a result the photons arrange as if we would have expected them to in the first place. I dunno just a thought that was provoked from your video. Keep up the good work!
This poor explanation makes the same mistakes that all the other poor explanations makes. I particularly dislike the part when they say a particle "knows" if it is being observed, etc etc. And then it devolves into erroneous conclusions involving "consciousness". The correct explanation is really quite simple: A particle is not simply a particle. It is a particle that is propagated outward "on" an invisible wave, just as radio waves are invisible. And yes, the propagation is probabilistic. Thus, waves are an inherent aspect of all particles, so there is no such thing as "just a single particle" without its inherent wave qualities. If two slits are open, the wave of course travels through both and the two then interfere. Since reality is literally infinitely times more complex than this reduced example, just imagine the infinite complexities of every particle's radiating spherical waves interfering with infinitely more other particle's radiating waves. It is a complex world out there, on the quantum level.
The most unsettling aspect of this experiment is how little attention it has received considering how fascinating it is.
If you read the comments on Reddit you see that almost everybody trivializes this experiment as meaning nothing because it is not understood.
This may be the single most important experiment ever.
It very well may be the first proof that were in a simulation

@@naakatube its not that simple.

This is an invitation to see a theory on the physics of light and time!
I have a theory, concerning "observation wave collapse"...
The field emitted by the test equipment induced union among the photons. Photons are, by nature, charged particles... as such, they are sensitive to any fields within their environment and must react to them.
Yucky man, simulation theory. The light waveform exists to save processing power. When not observed an approximation is sufficient, when observed all the maths get done and a specific location is determined. Kind of like textures changing quality in a video game when an object moves from the background to the foreground. The truly terrible part is because shortcuts are being used while rendering our existence, we can be moderately certain we are not on a high end computer in a laboratory running a perfect simulation, but on some kid's playstation where you need a few tricks and shortcuts to keep things running smoothly.

One more thing, the most mind boggling part of the experiment was left out of this video... where a detection mechanism was placed directly AFTER the slit. The waveforms collapsed BEFORE the slit indicating that beyond the slit the particles “knew” they were “going to be observed” and therefore “should act like particles”.

No. What's happening is the virtual reality rendering engine does not render what no one is looking at or track the movement of every particle in the universe. That is a huge waste of computational resources... so it cheats and uses probability distributions.. it saves more than 99% computational resources that way..

I'm five years late but there seems to still be conversation here. My favorite interpretation of these results is not that the act of observation collapses the wave function, but that when we measure it, it becomes entangled in its environment. This gets into the Everettian interpretation of quantum mechanics, and removes the collapsing of the wave function as a piece of QM. Instead, all possible outcomes really exist in different branches of the wave function, and by detecting it at the slit, you've limited the possible outcomes of its position because you are also entangled with the environment that the particle becomes entangled with. Not only does Everettian QM provide an explanation for the double slit experiment, it provides an explanation for the Delayed Choice and Quantum Eraser variations of the the double slit experiment. Whats more is, it doesn't just provide a framework that makes these outcomes make sense, it is the expected behavior. But, we have to come to grips with the mind boggling strangeness of the idea that every possible reality that ever could have happened from the beginning of the universe up til now and beyond all exists in a real quantum superposition. There's a branches where i've died of cancer, branches where the nuclear bomb at hiroshima didn't fire, a branches where our sun and solar system never formed; but we will never access them.
Sean Carroll goes further in his book Something Deeply Hidden, where he then uses Everettian QM to derive spacetime from entanglement, and gravity as an emergent property of entangled particles; eliminating the need to quantize gravity, something we have been trying to do for nearly a century with no success. It allows QM and GR to play nice.

@@Sharperthanu1 "Question:Why isn't the wave function entangled with its environment BEFORE we measure it?"
In a way that's what I want to know. More specifically, what events make the wave function collapse ?
I mean, even in the vacuum of space there's still something, there is no (truly) empty space. In our world there's also air, and lots of light (these experiments are not done in the dark, right ?). So why isn't the wave function collapsing all the time ?
First of all, there is no collapse of the wave function. The wave function is not a physical object. Secondly, entanglement is a reversible process. Measurement is, by definition, irreversible. More precisely, measurement is irreversible energy transfer and if you do a measurement on a quantum system, then you have irreversibly destroyed the system.
From this point going forward I shall address you as "Lord Joe Archibald Scott"...Bringer of wisdom and humour and......Stuff!
I'll allow it.
When I first heard about it actually changing when observed my mind was blown. I literally said out loud "there is NO WAY that happens!" It just seems unbelievable and surreal.
The "which way detector" is an active detector. Human eyes are passive detectors. The which way detector actually alters one slit's wave pattern such that it does not interfere with the other slit. Hence no interference is interpeted as particle behavior. Observation itself has nothing to do with the change.

I agree. I believe the detector is altering the results. Nothing more nothing less. Because the behavior is consistent it's obviously not 'a flaw in the matrix'@@FreeSkeptic

There is no need to introduce “consciousness” into the description. Once any information is gleaned about the electron, it’s fundamentally changed. It takes a energy to retrieve information from the probability wave function, and that inspection (be it light, or a detector) changes the probability from anywhere to somewhere. All “which way” data that you can have will always require you to alter the probability.
The only way you can ever have an interference pattern is if you have no information about the electron, which would keep it traveling through both slits and interfering on the other side of the slits. Collapse anywhere, and the wave becomes localized.
THANK YOU. It's extremely frustrating hearing people say things like, "when you LOOK at it," as if when a human scientist's eyeballs are "watching" the experiment.
It's because the detector ITSELF interferes with the wave. Misunderstanding these opens the door to so much woo and pseudoscience.
@@unknownuser8838 not so fast.
They put the detector behind the screen. After the particle had passed through the slits.
Here is the problem with what you are saying. It is true that making an observation (measurement) has some affect (even if very minute) on the photon, but how does it know if someone is taking a measurement (watching) , or if it is just passing by something else that just happens to be there like say a gravitational force, or some other particle, or some small piece of matter?
@@danricci7855 Reality is always watching, the information is censored, so we cannot know.
Even when the measurement occurs after the event , it changes itself backward in time.
The common denominator is knowledge, if we gain knowledge of the system it self censures.
@@gerardjones7881 Yes it appears that it could be that the photon knows what the future is and adjusts accordingly, but if that were true then that would be deterministic, whereas quantum data strongly shows randomness, not determinism.
Terribly explained, when the particle is "observed" it's not a conscience observation, these things are way to small to observe through any microscope so you must bounce another particle with a known velocity off the photon and measure how that changed your original particle velocity. Through this you can determine which slit the photon went through. And the act of doing this collapses the wave state into a particle state. In physics the term observation means to interact with the system in some way. not necessarily see it. (Im not a physicist so my explanation is awful but not filled with fake info like the vid)
Well, if this all is a simulation, one way to optimize it is to render only what is observed.
EXACTLY
Towards the end, at 5:54, you mentioned "How does conscious observation change the nature of matter?". The fact is conscious observation does not collapse the wave function, measurement does. There is a distinct difference between the two. Great video, thanks for posting.
You're correct. I would like to know what the "measurement" procedure is. A tape with inches and feet? What is the process scientists use to "measure" light waves/particles?
Good point. But, the measurement is a record of something in a collapsed state because it needs to be. The information is preserved/a record for eventual conscious observation. A delayed, conscious observation is still a conscious observation. The particles can't be tricked. I've always felt this behavior, and how entangled particles behave, to ultimately be connected.
maybe as thw water in the tank experiment. the light is in fact a particle that avels in waves, and thats it. the observation with electrical devices afect them
@@elpelagabriel1755 or the light is always the wave which can be observed only when it collapsed to a point-object state. the measurement (interaction) collapses the wave (making it concentrated in space coordinates)
@@JoeL-kn9tc there is no measure.. it just conscious observation
Double slit experiments kinda support the simulation theory in such a way that our reality/universe blinks in of existence only when needed or when someone's looking. Very similar to computer games where graphics are being renderred only when the character has to interact with the environment which needs to be renderred. What a great and clever way to save up on processing and computing resources :) Just my 2 cents

Would doing the experiment itself be an act of conscious observance?
What a fantastic comment!
Nope, because you could just set it up, walk away, and then come back later to see the results. Also, as was stated a few times in the vid, these experients have been run many times, in many different ways, and the results are always the same.
Also, the way the experiments are set up are just for lab conditions, for ease of observation - they happen naturally in nature all the time, and is observable and predictable.
There seem to be two schools of thought. 1) I've heard that the "observation process" collapses the wave function. By this people are thinking that a conscious observer (or something special about the organic matter making observations) is influential on matter being observed. I can see why this is attractive as we are organisms made up of the very particles in observation. As we see a great deal of connection in all phenomena throughout the course of our daily lives... certainly we'd like to see this same connection at more fundamental levels too.
But then there is 2) And from this I've heard that it's the "MEASURING PROCESS" that collapses the wave function. And I need to be very clear here that I'm talking about MEASUREMENT and not conscious observation. This to me suggest that the matter we are dealing with is so small in magnification that the properties with which we extract measurement are inaccessible (kind of like a truck scale weighing a piece of dust).
So my questions from this video and these two different schools of thought is.... What is really collapsing the wave function? Is it consciousness or measurement? I don't think these two things are the same. There must be more conclusive data and experimentation with which we can affirmatively rule out or tie in consciousness. If it's measurement... and this is creating the major difference in the double slit experiment... what are the fundamental properties of measurement? A measuring device and its process must be in some way composed of the very matter being measured.
Another way to say this might be to say...."One hand can shake another... but a single hand cannot experience the 'hand shake' by itself.' We're approaching a point where matter cannot deliver an understanding of itself now matter how it's re-assembled for the purposes of the question. Even Allan Watts the philosopher said too. "The Godhead cannot be the object of its own knowledge".... fire cannot burn itself, the tongue cannot taste itself... teeth cannot chew themselves... etc etc.
At the end of the day..... Matter might not be able to explain itself.. (or Matter to itself).
I have no Physics background whatsoever.....but this stuff does seem quite important and has contributed to our lives greatly... therefore I do try to understand. :)
We're trying to understand reality with brains designed for finding better berries. I don't think it's going to work too well.
Its 2. Measurements.
Indeed the measurements are not passive. This has the same dilemma as our attempts to study signs of life on Mars: To analyze the samples that our rovers collect, we INCINERATE the samples. Even if Curiosity collected a bunch of Martian microbes, we still wouldn't "observe" that as anything other that traces of organic compounds. Because we incinerated the microbes to "observe" them.

I found the Kubrick variation to be the best. He used a pair of entangled party girls to demonstrate the double slit experiment in Eyes Wide Shut.
I took a hard look at the data and came away satisfied. Perhaps if I had kept my eyes shut, my waveform wouldn't have collapsed into a load of messy particles.

Stop saying 'observed' when you mean 'interacted with'.
A reply to your double slit experiment! Question the observer effect, that changes the results! What or who is the observer? That answer seems to elude everyone in a scientific field!! It annoys me!
Who is the observer is the key to double slit experiment.
When asked who are you, I’ll give my name, my work, my family, etc etc etc!
But really who am I? Let’s compare the heart and the brain. Dr’s can remove a patients heart and reconnect it to a pump to keep the patient alive! We can’t do that with the brain, so it has to be a thought experiment! Let’s imagine that such a procedure could be preformed! Now with the brain removed and you ask the patient “where is the me that has a brain?) . “I” “Me” most people believe that they have a brain, as if there were a separate entity that possess a brain! There’s the rub! When I say the words “I or me” there is a mis-perception” , that there is a tangible entity “me” or “I” that has a brain separate, apart, that “I” possess!!!
The “I” that believes that “I” exist, is the error! What the so called “me” actually is, is in the make up of the brain itself!
The neural network, the synapsis and receptors, all the connections, the memories, the upbringing, the experiences, the programming of society! All of that creates the (mis) perception that I am a tangible entity that I call me!
That gives the “i” the observer in the
“Double Slit Experiment” results! The belief that “I” am objective entity or observer exist!
The belief that “I” can observe objectively is false!!!
The belief that I am a separate entity observing the experiment has an effect on the experiment!!!!!
A belief in an “I am” separate from the experiment creates the conflicting results!
Like trying to objectively observe the laws of nature, when I am a part and product of those very laws! It’s impossible! To be objective, you would have to be separate
from those laws!
With the revelation that there is no tangible “I”, dare I say that “I” don’t exist, well not as I believe I exist!
With the (mis) perception that I am, a tangible separate from; the universe, the
Double Slit Experiment cannot be understood!
“I” life itself, this seemingly different form was labeled with a name Randy!
Once upon a time I believed that I had a brain a mind that is mine! Now I realize (if only intellectually) that I don’t possess a brain/mind,
But am a product of the brain!

Dude at first I was like what the fuck is he talking about and after two mind blows later I understood what you were talking about.
So could we in theory communicate through time with this? If the observer choses to observe it will affect the outcome so by chosing and not chosing you could send a string of 1 and 0 (garbled by probability so you would have to do it a lot of the time so the recipient of the message could see the most likely message). And what Joe said means that this works back in time too so it would effectivley be instant communication even though one party will talk a lot later. But the downtime between messages would be near zero.
Unfortunately no because in order to decipher the message you need to know the Futures pattern. That's the dumb way of saying it.
Sadly no because the person on the other end of the quantum entangle communicator collapses the wave function when they try to observe the particle/photon and thus have no idea if it was collapsed by your detector or theirs. All of them will be particles without the wave function so all would be ones or zeros in your scenario I think.

@Alex DelRio No, we would have proof that the wave function interacted with "something" physical and collapsed. Consciousness really has nothing to do with collapsing wave functions. In the double slit experiment, you can run it without a detector and see the wave pattern. You can then run the experiment with detectors that tell you which slit the particle/wave went through and you will have the particle pattern. You don't have to be in the room to consciously observe the detector. You can leave the room an go have a smoke and come back and the wave functions will still be collapsed.
I'm gonna say it. Any second now. It's a glitch in the Matrix. There we go.

Proving that reality is a collective hunch..
1:58 Wrong! All the slit experiments show that lights is waves, NEVER particles, the same is true for all frequencies of electromagnetic radiation. So-called 'photons' do not exist, there is no such things as light particles and there is no such thing as "wave/particle duality".
Physicists had developed a system for analyzing waves, so they applied their wave-system to matter by treating matter as waves, then followed the converse proposition by treating waves as matter. The wave/particle duality is merely the nonsense of misapplied system analysis.
Electromagnetic radiation (EMR) is waves at all frequencies, never particles. Every experiment shows light is waves, there are no EMR particles, there is no duality. What they call "single photons" is a high frequency interrupter relay transmitter switch used to produce single separate individual wavelengths, like this ~ ~ ~ ~ ~ not "photon particles".
Continuous waves produce interference patterns and intermittent separate single waves also produce interference but at a slower rate/intensity because of the gaps between waves. The interference is the proof that light is waves at all frequencies, never particles. "Probability waves" only exist in researchers imagination, that's why nobody (including de Broglie) could design an experiment which shows light is particles.
The photoelectric effect is easily explained by blue light having the right frequency of positive/negative magnetic induction (alternating push/pull) to magnetically agitate a negatively charged election out of it's shell orbit, that's why the photoelectric effect does not work at higher or lower frequencies - nothing to do with "particles". Did you believe red light was waves but blue light magically manifested 'particles' which disappeared again at higher frequencies.
Electromagnetic Radiation (EMR) is waves at all frequencies, all the experiments show light is waves, there is no experiment which shows light is 'particles'.
4:00 The "photon detector" is an imaginary mathematical idea, not a real device. It is impossible to passively tag a wave (or a particle if you prefer) with an identity as it passes through the slit, the only way to detect a wave is to put physical matter in the path which consumes the wave energy by absorption so obviously nothing would come out of that slit. It's the same wave which goes through both slits and causes interference from two separate slit sources on the other side. The interference experiments do not have any detector because that would block the wave and cancel the interference, that's why NONE of the interference demonstrations have detectors.
There are hundreds of videos showing the actual double slit interference but none showing the actual wave function collapse as the interference pattern disappears into observed "particles" because it's only a thought-experiment.
Quantum electrodynamics textbooks give a summary of the discussions between Bohr and Einstein in which they each propose a variety of impossible imaginary "detectors". They were just talking, the 'detector' was just an idea.
Physics had a well-developed analysis of waves, so as a thought experiment they started treating matter as waves, later they reversed the thought experiment and started treating waves as matter, the self-induced paradox of the two thought experiments created wave particle duality and 'spin' only exists in the minds of believers, not in reality. Schrodinger published his cat in a box thought experiment only to demonstrate the absurdity of the wave/particle duality idea, Schrodinger was later very surprised to see his absurd cat in a box story being used to demonstrate the true nature of state vector collapse wave/particle duality.
Relativity and Quantum Electrodynamics are thought experiments, that's why cosmology and QM are a cult-like belief system with a priesthood guarding their made-up doctrine by excommunicating doubters, for example, it is impossible to have academic career in physics if you say there is no proof that black holes exist. There are some places in the universe which seem to have more gravity than expected and some of these places seem to have more gamma radiation than expected, that's all we know about "blackholes", everything else is speculation, but if you publicly say this you become an outcast without any academic employment prospects.
Go and search for actual experimental evidence of wave/particle duality and you won't find it, because it does not exist. Electromagnetic Radiation (EMR) is waves at all frequencies, never particles. You must have suspected this surely?
obviously that detector has a bad motivator
Yes I like that LOL It is not just looking! Even in the two slit experiment it is turning on an electronic detector the collapses the wavefunction Ψ. This video explains the experiment: ruclips.net/video/MTDwUeIolAQ/видео.html

There is a version of this experiment where detectors on the slit determine which one the photon passed through, and there are two observers. One has the detector information and the other doesn't and both patterns emerge! So two observers can see very different versions of reality.

It gets weirder still. It isn't just photons that don't this but electrons and atoms too. I read that someone is trying to do this with a molecule the size of a small virus. If proteins can behave this way then what does that mean for biology?
I know I'm late to this, but you always have to remember one thing. Photons are MASSLESS energy particles (or waves......), while anything else is such as electrons and atoms DO have mass. So correct me if I am wrong, but I don't believe that proteins can act like this. (I'm only 12... don't judge me please xD)
Everything can act like a wave including molecules (proteins), it's just that the wavelength is inversely proportional to mass so it becomes undetectable at some point (the size of a very large molecule).

Yah this one was bad
I know this is an older video and you may not check the comments anymore, but I've always wondered what if a third slit is added? Is there any change in the results?
if photons travel at the speed of light then from their perspective time has stopped. a photon experiences the entirety of its existence simultaneously. so it doesn't seem so bizarre that it would "know" the future as it is experiencing that at the same time as our present; as one stationary line between where it started and where it ended. we measure one slice of that line and call it a photon. it's only from our perspective that it would seem odd that cause and effect are backwards. i know this doesn't really explain exactly how the photon "knows" to change the result we see, but it must be something to do with forcing a particular future to occur by knowing in advance which slot the photon went through. we can't know that information without it reducing the possible outcomes and from the photon's perspective that outcome is already happening as one static picture.
Ok... Now explain why it happens with particles with mass.

Observed = "Measured"
Yeah this really bothered me. There is no requirement for "conscious observation" for waveform collapse. This video is such woo-woo.
Exactly, it gets used sooooo much to support things that it simply doesn't support, it bothers me that rational people do this.
I've heard this argument before. But it is incorrect. Consciousness is absolutely required to collapse the wave function. Not only that but it must be your own consciousness. Every measuring device, and every other observer will necessarily become integrated with the wave function, including much of your own body and brain, until your own personal consciousness requires its collapse. It makes no sense to imagine a wave function collapsing for anything else. If you think it does, please explain what physical process can cause a wave function collapse.
entaglement in a quantum system (IE measurement) is what alters the wave. It's not consciousness. It's measurement.
If you want to consider a 'computer' conscious. Ok.
Read about Schrodinger's cat thought experiment. It explains how a cat can be both dead and alive at the same time. How is that possible? Because from the point of view of the external observer, the wave function did not yet collapse, because the contents of the box was not yet observed. But surely the cat would qualify as a measuring device, and yet the wave function does not collapse. Instead the cat becomes integrated with the wave function. And so would any conceivable measuring device.
Also imagine that Schrodinger's cat is inside Box A, and Box A and observer A is inside Box B. If observer A looks inside Box A, then observer A becomes integrated with the wave function contained in Box B. Only an observer outside Box B can collapse that wave function.
If you follow this to its logical conclusion, it means that the only consciousness that can actually collapse the wave function from your point of view is your own personal consciousness.
For every action there is a reaction. Why would people expect the action of observing be any different? Legitimate question as I am struggling to get my head round this.
Because it means that the human consiousness is a lot more intertwined with life itself than we may think
Particle, wave....
ruclips.net/video/nnkvoIHztPw/видео.html
Your confusion stems from you making a false equivalence. "For every action there is a reaction" is Newtonian physics, and it realates only to classical mechanics, in particular; mass and force. The 'action' in Newton's case was regarding the application of a force, not the 'action' of an observation. That's why people didn't expect the mere observation of a natural occuring phenomenon to have any effect on the experiment, because the action of observation didn't input any mechanical force into the proceedings, you see?
That it did in the double-slit experiments is what blew the lid off Newtonian physics (well, that and Einstein's Theories of Relativity) and ushered in Quantum Physics.
Dear Joe, you need to see the weak measurement experiment! If particles are weakly observed the interference pattern is not destroyed!
Technically it's still gets destroyed it's just not as badly destroyed because it's not as much observed.

I have yet to perfect that motion
I do a lot of 3D modeling for architectural visualization and have to render images at the end. One way to cut on render time is to pre-calculate light bouncing in 3D space in the scene and save it as a file the reuse it for the final render. Now, i imagine that a simulated Universe must have the same mechanism that will save on render time.
Albeit three years late, I will throw in my 'particle'. When we initiate an electrical beam (i.e. turn on a light), we actually give excitation to the 'field', where the entanglement begins... causing the particles (photons) to vibrate (oscillate, i.e. wave).
Since the particles are in superposition, they are "already in both places", just not yet vibrating at the other end because entanglement hasn't occurred on that other end. The excitation would travel at 186,000 miles per second.
In this way, light could be expressed as a wave AND a particle in the same model. Light is a particle, being vibrated (oscillated) in superposition in a field that is expressed as a wave at the speed of entanglement (not the speed of light).
Someone has to check this thoerie. Sounds interesting tho
@@mikeock2087 it's based on Quantum Electro Dynamics, QED, developed by the great Richard Feynman. He was quite disappointed to realize it comes with all the same baggage as, and explanatory problems of, treating light like a wave. Instead of the Ultraviolet Catastrophe, it creates the Vacuum Catastrophe. While some credit him with 'explaining' the DS experiments and even the phenomenon of Iridescence; he himself was well aware it didn't count as an Explanation of either phenomenon. Next theory...
Um.. if the observed data was encoded as the product of 2 multidigit (billion digit) primes, not individually observed, then if the wave collapsed this suggests that in future quantum computers could find the individual primes, thus giving comfort to those trying to develop quantum computers... or if the wave does not collapse - because it remains always computationally impossible to find the 2 primes - not.
I rewatched this, again. (I have watched virtually watched every one of your videos, kudos.) One thing you said may be pure genius. "Non-locality and non-temporality". Does this suggest something? Consider special relativity. Time and space are inseparable and are relative. Sorry to reDO YOUR BRAIN IN. But it strongly suggests that our observation of reality is, well, strongly relative. We can't explain our observations because we are the observer, not the participants. Just a thought. Maybe there is a unified theory if you quantise special relativity. (Visualise Einstein superpositioning in his grave). Worthy of a video?
In my unprofessional, uneducated layperson understanding of it, when you "observe" it, you are using detectors. In order to detect something, you have to interact with it. It's that interaction (however it is being achieved, I don't know how the detectors do the job) that causes the waveform to collapse. It's not that the particle/wave senses your gaze or your consciousness, it's that the detector has disturbed it.
vinsanity982, yes. This is so obvious, it’s incredible that any educated person could think otherwise.
Joel Tunnah The eraser theory disproves this
The Detector doesn't interact with the particles like you think, it just observes them and inside the detector and its software, calculations are made, just like a camera doesn't interact with you when it snaps your picture. Someone may be snapping your photo from across the yard, you wouldn't know it though. Somehow the light knows someone is hiding in the bushes, snapping their picture! This is my very slightly educated understanding anyway :-)

Can you explain how two planes crashing into two buildings could make a third building collapse in the exact same way the first two buildings collapsed. All three buildings collapsed at free fall speed, encountering no resistance.
I have asked and searched for the answer to this question for 20 years. No one can even offer a theory of how it would be possible. Can you?
'Observing' a photon means detecting the photon as it moves past the observer. How do we do that? Well presumably we measure the change in an electro-magnetic field as the photon moves through the field. Huh? Let's assume the photon is a super-tiny particle of light or a super tiny wave - whatever! My electro-magnetic detector is a device which produces an electro-magnetic field and it records changes in the field caused by some other field which interacts with it. That 'some other field' is the photon we are trying to observe. So the only way we can detect the photon is to hit it with another photon.... Yeah, I know this is getting probability and certainty all mixed up... but surely this has something to do with it?
This is the a quirk of how time works. For the photon, no time passes from its creation to its destination. But since we experience time differently. The reason the photon changes is because, from its perspective we are going back in time to change its timeline. Essentially it has already done what we are seeing it do. Therefore when we change something, to it, we are time traveling. So as I said, simply a quirk of time, and essentially the none existence of time at lightspeed. This is also why if you move close to lightspeed, you experience time slower than other people, essentially traveling forward in time in relation to everyone else. If you could move at lightspeed (without hitting anything) you would instantly teleport to the end of the universe. Both the end of time and the literal edge of the universe. To teleport, just move at lightspeed. This is actually the basis of the "relative" part of general relativity. So to warp everything. To the "big bang" the universe has already ended. To that blob that went "bang", the blob has already expanded to the end of the universe, while to us it's only the beginning and still expanding.

I actually heard the photon thing from Joe Scott on his video about, why is light so slow. I don't really have any math to back anything up. I just "put 2 & 2 together" and got that. I don't honestly have any way to test it. I just used logic and reason to make sense of things that baffle so many scientists. And I'd assume others have come to the same conclusion and the thing that baffles them is trying to find the math proves that hypothesis. And math doesn't like time travel, since time travel brakes causation. Causation is the basis of all math.
PS: I have other observations that talk about quantum fields and how the atom is probably the long sought Graviton.
night607000 please do share
This theory sounds plausible.
But since time wouldn't pass for the photon (or whoever was traveling at lightspeed), meaning it would take an infinite amount of time from the traveller's perspective, you would be stuck traveling forever before you got anywhere from your perspective.
"He's watching us again. Let's flip him out."
“Observing” the particle would be better explained as saying “measuring” the particle. The wave form collapsed because it was measured.
No!!! That is not compatible with the results of experiments.
@@aaroncurtis8545 That's exactly what's been done in all of the experiments. Looking at light doesn't make the wavefunction collapse. Measuring it does.
@@4Leka I think you think you're telling me something I don't understand... But I'm trying to tell y'all that there's something deeper there that you're not understanding. It's logically akin to people not understanding the difference between 'saying what you mean and meaning what you say' in Alice in Wonderland. But truly, you're missing something that the founders of QM saw in this process which has never been resolved and is still referred to as 'The Measurement Problem'. There's a Reason the word Observation was chosen, as opposed to the word Measurement, and you're not getting it.
@@aaroncurtis8545 "...and you're not getting it". That'll be because you are not explaining it.
What a misinformation stuf! There is no observer, there is measurement in physics, not observer! this is messing up with words…just for clickbait…
You can't passively observe subatomic particles, to measure them you must hit electrons with photons or some other means, an active process, which means it's impossible to observe their behavior without interfering with them and changing their behavior. They don't behave differently because they know they're being watched... that's woo woo.
Thank you so much. I’ve been obsessed with quantum mechanics videos for the past two years and non of the videos I’ve watch have defined what measurement or observance is until yours.
The "which way detector" is an active detector. Human eyes are passive detectors. The which way detector actually alters one slit's wave pattern such that it does not interfere with the other slit. Hence no interference is interpeted as particle behavior. Observation itself has nothing to do with the change. Some have speculated that this experiment somehow proves consciousness extends beyond the mind.
I think why they say “observed” they mean interacted with in same way. Eg. in order to detect a wave/particle you have to interact with it. My head hurts....
Particle, wave....

3:43 "this experiment has been replicated..." I cannot find any video on RUclips, or anywhere else on the internet showing this experiment actually being replicated, nor do I understand how you would replicate the experiment. I have seen the interference pattern in physics class in highschool, which explains that light acts as a wave, but I do not remember ever seeing the "switch" from when the light acting as a wave when observed/unobserved, to acting as a particle otherwise. Has anybody actually seen what this experiment involves? I mean, it's almost like a contradiction to say that if unobserved it acts one way and when observed it switches. How do you know how it behaved when it was unobserved.... if it was indeed "unobserved"?!
When we say unobserved we mean not using a detector to see which slit each photon went through. What you did in class was unobserved, as in you only viewed the projection
I'm guessing the reason observation changes the effects is because the quantum world is tiny as fuck. So any input of energy from a macroscopic scale is going to be like igniting a nuke to quantum particles, atoms, photons, etc.
wut... and I thought the concept of ten dimensions was mind-boggling...
It is not just looking! Even in the two slit experiment it is turning on an electronic detector the collapses the wavefunction Ψ. This video explains the experiment: ruclips.net/video/MTDwUeIolAQ/видео.html
This seriously keeps me up at night. Would like you to do a video that talks about the different kinds of matter that have worked the same way in the double slit experiment and ones that haven't.
It's a head scratcher.
Me too! It is not just looking! Even in the two slit experiment it is turning on an electronic detector the collapses the wavefunction Ψ. This video explains the experiment: ruclips.net/video/MTDwUeIolAQ/видео.html
@@Dyslexic-Artist-Theory-on-Time that's an empirically disproven statement based on a lie. Like, actually contemplate the last 120 years of experimental results, and that becomes obvious.

In my opinion, this is the most fascinating experiment ever conducted.
Your opinions are pretty weak, Dude. ;-)
There are no dualities in nature. Light is neither a wave nor a particle. Light is a coaxial circuit made up of both longitudinal and resultant transverse electro magnetic disturbances in the ether. Once we wrongfully believed the ether did not exist, every phenomena had to be explained using bumping particles. The fact is that everything is fields and fields are not particles. Light does not travel but is merely a propagation of a disturbance in the ether. Quantum theory is based on a misunderstanding and will one day face its deserved demise. Joe, you presented the current wrongheaded issue well however.
Joe has (I believe) advanced in his understanding of the double slit experiment since he made this video. His misunderstanding is well described and countered in other comments, but, basically, consciousness and his emphasis on it, is a misleading factor in this experiment.
What if they’re waves OF particles?
l don't believe you should think of this as your typical "wave" but rather as a probability wave... the particle can show up anywhere in the interference pattern but will only create the interference pattern after enough particle have gone through the slit to be statistically significant. This is the basic mystery... what does nature know or care about probability waves?
It doesn't help if we send them through one at a time, and they still interfere
@@aaroncurtis8545 What happens if you send them through one at a time every 12 days?
i will never understand this
Yeah probably better that way. Best not think about it till someone figures out how to explain it to normal people
I've always been amazed at how the universe has such strange properties as this (episode) and quantum entanglement yet in no way is it possible to send information backwards in time.
For example I'm sure the very last study in this ep - to affect a photon in flight by changing the end condition of its path - could not be used to send a laser communication around the world and provide the effect of negative latency when read at the mid point by affecting the light not when sent but when returned.
It has something to do with the endochronic properties of resublimated thiotimoline. There's a thesis somewhere that goes into detail about it.
I stopped looking for ghost and ufo's when i learned about this on youtube this is more disturbing and unsettling than anything supernatural.
In relativity, from the perspective of light itself, time around it has completely stopped and the light exists in all places at once…this must be some part of the explanation of the delayed choice experiment….as something approaches the speed of light time slows down, at the speed of light time stops, putting the light or object in all places at once, because there is no time for something traveling at light speed….so if there’s no time movement at all as it travels through space, there is no before or after, but as an enthusiast I’ve never heard this idea echoed before
obviously a simulation
#conspiracy
anyone else from 2019?
😮 I’m in 2019 right now! how did you know? 🤯
Going into philosophy, would anything exist without an observer?
That's the theory of biocentrism
Things exist without observers. Observers don't exist without things to observe.
+Congruesome It might be true that this relationship goes both ways.
+Congruesome: When you think about it, or bodies including the brains we use to comprehend the universe are made of the same stuff as is being observed/measured. We ARE a part of the universe. We are, ourselves, part of the observation.
+Congruesome The question becomes what is it that is REALLY doing the observing, and how far removed from the observation is it?
Nice work broseph, more quantum mechanics videoooooooooos pleeeease subbed and liked :)
+ERA IRiS Hehe... Thanks man!
I like this "Broseph" moniker for our friend Joe. I see it as an amalgamation of Josephus (famous Jewish historian) and The Dude, from the The Big Lebowski. The Broseph abides.
This is an invitation to see a theory on the physics of light and time!
Perhaps all matter and particles are merely the constructive interference of the very universe itself. This would explain why matter appears to not be absolutely definite at some points, and why events in the future might affect it in the past.
😂 feels like we are living in some sort of computer simulation. If we observe something there is no need for the wave to continue to calculate what the future state would be. Or if we know that in the future we will have a change no need to calculate the wave before this. My brain is melting.
Space-time is actually thought-energy and we are all just making it up as we go.
Thanks for coming to my TedTalk.
What if these quantum particles are ALWAYS a particle and a wave at the same time and these experiments are inadvertently filtering for one answer or the other?
How are they "observing" which slit it goes through? There must be some interaction with the particle along its path for this to be possible.
+Joe Scott
I guess the fact that we now have functioning quantum computers proves that the "creepy" duality is, in fact, real.
Err…No, quantum computers take advantage of quantum tethering which is a separate phenomenon.
Maybe the device we use to measure which slit it goes through robs the particle if it's "waviness". Maybe those waves are being cancelled before it enters.
I've never seen any video of this aspect of the experiment - the measurement of which slit it goes through - being conducted. I'm not sure if the technology exists to measure where a single particle will go with out stopping it… but the fact that the detector is only placed on one slit - the assumption being that if the detector does not register, that the particle must have gone through the other slit or collided with the frame - does, logically, accommodate for the possibility of the observation interfering with the experiment. If this experiment has actually been conducted with such a detector in place, and this phenomenon has indeed been produced then, yes, it is really weird. So, I've answered my own question.
the double slit experiment has always been the most interesting scientific experiment ever conducted to me and I love listening to the theories people come up with in an attempt to explain the weirdness of it and the possible implications
The "which way detector" is an active detector. Human eyes are passive detectors. The which way detector actually alters one slit's wave pattern such that it does not interfere with the other slit. Hence no interference is interpeted as particle behavior. Observation itself has nothing to do with the change.

i think it can be explained by our limit as the observer. We see the world but don't see what we aren't capable of, aka 4d, and then 5d, which creates interactions between light reality time and space that we cannot concieve with sight alone but we can imagine it only by accepting that we cannot
That skit of hitting your nose, well 6 years ago I got in bed around 10 and suddenly the back of my head felt like it was hit and started hurting so bad I threw up and got so sick. lasted a few minutes. didnt hit my head or anything.. Then the next night same time going to bed tried scooting back against the head board to sit up in bed and hit that spot against the wooden head board and felt the same pain for the same amount of time. I literally hit myself so hard i felt it 24 hours earlier. There are things in this world that dont make sense (also my wife was there both nights and says my memory is right just in case someone was wondering if I hit my head so hard it messed with my brain and made me think I felt it the day before)
The answer is that the experiment did not, and never has, “shot” particles through the slits. It’s only and always a wave, which is not a thing - a “wave” is a field perturbation, nothing more. The act of “observing”, ie interacting with the wave with matter, is what messes up the wave and causes the lack of an interference pattern. When they stop using matter to interact with the wave (“observing”), it goes back to the normal interference pattern.
There is no “duality”, and nothing weird going on here. The only thing that’s weird is scientists belief that the universe behaves in inexplicable ways.
the background music is creating an interference pattern in my brain
This comment section is hilarious :D
The role of observation within quantum mechanics sounds a lot like the chunk loader in Minecraft.

WE'RE IN A SIMULATION M8
It is not just looking! Even in the two slit experiment it is turning on an electronic detector the collapses the wavefunction Ψ. This video explains the experiment: ruclips.net/video/MTDwUeIolAQ/видео.html

Single best Double Slit Experiment video I've found (and I'm a collector)
1:53 How did Newton do that given he died 74 years before the experiment was conducted? 💀
Anyone else get a weird... doomed feeling watching this video?
GOD !
works in mysterious ways 🤔
Well God needs to spend less time in the slits and more time on world hunger.
Or the particles are being put into quantized positions on gravity waves?
Gravity waves are a fairly recent twist on the situation right? I hope this will explain some things that just sound like they used the process of elimination without knowing all the possibilitys.
+crowtep1 yeah, I could be talking out of my ass because I'm speculating that particle positions are not only quantized when in atomic orbits but in all dimensions (however many there are). Since gravity waves bend/stretch time and space, the quantized positioning would be further apart toward the peaks and troughs of waves. In the "observer" experiment the particles lose some energy due to the measuring process and thus skip across fewer quantized positions making the "double slit "shadow".
+believerornot do we know how much g waves will effect positioning yet ( probably right in front of my nose, sorry it's late). Might there be a gravitational effect of observation/ measurement that would effect the energy in the results?
crowtep1 well I'm speculating that gravity and gravitational waves do have an effect. I'd like to see the double slit experiment performed in the space station.
The result would not change.
Joe, I tried to tell you
"Existence and CONCIOUSNESS are
Synonymous!" We've been anylizing the universe from the wrong perspective. We assume that we (lifeforms) are the only perceiveor! Not necessarily true. All lifeforms are expression's of, and extensions for, universal conciousness...
Fascinating! I have more questions than before I watched the video
So here's my thought. Perhaps the double split experiment during observation gives credence to the hologram, OR the matrix theory. As if it was a program fail safe in case we (the observer) discovered this. And as a result the photons arrange as if we would have expected them to in the first place. I dunno just a thought that was provoked from your video. Keep up the good work!
This poor explanation makes the same mistakes that all the other poor explanations makes. I particularly dislike the part when they say a particle "knows" if it is being observed, etc etc. And then it devolves into erroneous conclusions involving "consciousness". The correct explanation is really quite simple: A particle is not simply a particle. It is a particle that is propagated outward "on" an invisible wave, just as radio waves are invisible. And yes, the propagation is probabilistic. Thus, waves are an inherent aspect of all particles, so there is no such thing as "just a single particle" without its inherent wave qualities. If two slits are open, the wave of course travels through both and the two then interfere. Since reality is literally infinitely times more complex than this reduced example, just imagine the infinite complexities of every particle's radiating spherical waves interfering with infinitely more other particle's radiating waves. It is a complex world out there, on the quantum level.
So, that does nothing to explain the difference in behavior. And physical interaction is disproven by experiment.
