It means classical physics is actually naive.
*Hi Cindy - - it means that CONSCIOUSNESS affects the natural world. GREAT video - - Cheers* 😊
I have a theory here: electromagnetism and electric field itself is not quantized, but the effects on particles it is, that's why you can observe single photons interferencing with itself. In reality there are electomagnetic waves emitted but they are too weak to trigger any measuring device. Prove me wrong.

@@Adam.Reader14 it's the best counter-argument to "i don't mind, i've got nothing to hide"
It's important to note that "observing" a particle is much more involved than what the word would imply. It's not a passive act, in order to observe a particle you have to hit it with another.
In such a sense, every single particle in existence isn't "observed" until it interacts with another, so for nearly the entire life span of a particle it doesn't actually exist, it's simply a solitary wave.
Underrated comment. When they stay stuff like this they make people think that literally “looking” at it changes it’s behavior and it’s like… no hitting it with another particle to see if it’s there or not changes it’s behavior, sounds way less mysterious this way tho.
What if information travels spherically outward from an event, then when an observer collects that information, it appears that the information exists only at the collection point?
@@marcusofranz1102 It’s still mysterious regardless. The act of observing, aka blasting photons to the particle so light can reflect back, changes it’s behavior for that specific time. When not blasted, the particle appears to be in two places at the same time. Still mysterious and more in the realm of quantum mechanics.
Yeah it seems just about every visual explanation of the dual behavior observed in the slit experiment depicts the observer as this passive eyeball or camera, and also uses the word "choose", as if the particle can somehow make a choice between passing through one slit or the other, or both, which is all extremely misleading.
Great comment, I've been waiting years for someone to bring this up. At the quantum level, how can the equip we use NOT interfere with matter?
Measurement, rather than observation. This is very important. Changes the idea of consciousness being involved.
Does it? What is a measurement without a result? How does a result become defined? It all leads back to a conscious observation.
@@steelersgoingfor7706 Correct. I wonder why that's so hard for people to understand. You can't have one without the other.
@@NATHANSREBELLION-zx4mn because people, whether aware or not, try to shape questions and answers in a way that at least leaves a possibility for understanding. Human fallacy.
@@steelersgoingfor7706measurement means using some kind of non-sentient tool to measure it, and the conscious mind can see the results at another given moment. Observation means that, at the time of the event, there has to be a sentient being watching it. You think those are the same?
Exactly, and I hate how wide-spread and misunderstood this experiment is. Much like how Schrödinger’s Cat was a thought experiment to show the absurdity in comparing our world’s physics to quantum physics, but instead every pseudo-scientist keyboard warrior on RUclips thinks the cat is somehow both dead and alive.
If physical reality manifests out of consciousness rather than the other way around then this makes complete sense. Everything is in a state of infinite possibility until the light of awareness shines on it at which point it manifests into existence
Ding ding ding. We have a winner. Also on that note everything is one and therefore we're all gods in a way as we can manifest whatever because all is us and vice versa anyway. Religion was made to take away our power and god was firmly placed outside of us to achieve that end. K byeeee

I think this is it. Using a graphics engine as an illustration, this experiment shows how the assets are rendered rather than show that we live in a simulation.
whose awareness, though? All organisms? or only humans?
Albert Einstein saying "God does not play dice" was not for the double slit experiment. It was actually for another Quantum phenomenon which he termed "Spooky action at a distance" (Quantum Entanglement).
Spooky action at a distance describes acausality. That means things happen for no reason.
Einstein didn't like that entanglement was described as an acausal quantum effect. He preferred to describe it accurately with the Einstein-Rosen bridge. In this way, entanglement isn't supernatural magic.
@@aaronjennings8385 to the frame of reference of something moving at the speed of light there is no such thing as distance

Indeed, it seems like 'Newsthink' just used chatgpt to write this article and as usual chatgpt got it wrong.
@Edmond White ask Leonard Susskind
This sounds exactly like Heisenberg’s uncertainty principle, in which a particle’s momentum and location in space cannot be determined at the same time, leading it to have multiple positions at once until observed. The same can be said about Schrödinger’s cat. In this thought experiment, a cat is in a black box with some poison. Next to the poison is a radioactive source. When the source reaches a certain count rate, the poison is released; the thing is the decay of the radioactive source is unpredictable, so cat at any point in time is both dead and alive until observed. Another analogy is if a tree falls and no one was there to hear or see it fall, did it really fall?
Both theories have been used to question the possibility of a multiverse where every possible outcome generates a new universe.
The idea of life being a “computer” program is logical, as almost all aspects of nature have mathematical attributes that are perfectly related to one another. Every possibility follows certain “coded” rules/axioms to carry out. In that case mathematics and physics is just the study of reverse engineering the program of the simulation. But when you reverse engineer a program and come across something that shouldn’t run, like photons arranging themselves when observed, you question whether this is intentional or an undefined natural error. It breaks the algorithm that we have documented for centuries.
The Heisenberg principle and Schrodinger's cat are derivations of this precise phenomenon.
Is math something created or discovered, either by the simulator or simulated?
We should be glad it hasn't been programmed by Microsoft or EA. HAHAHA
Interesting tying this all together, schrodinger's cat makes sense in this context, used to think it was a logic thought experiment (rather than trying to understand a physical phenomena)
Yes, the tree fell. But did it make a sound if there was no one there to hear it?
It is impressive that these physicists managed to isolate a single photon

What effect does the "measuring device" have on the photon? 1:29
What has been demonstrated is that this measurement device affects the photons, not that the photon knows it is being observed.
I think there is another exp were measurement got delayed and the system behaved like particles. So is not the measurement device, but the fact that it will eventually get measured, that make it behave like that 🤯
@@tomich20 yeah, before being measured it showed interference characteristics but after delay when it got measured, the characteristics instantaneously changed to photon
Yep iirc this is one of the main hypotheses put forward as an explanation for this phenomenon.
I agree her definitions and loose use of words is a not describing the effects accurately.
Wrong
Server admin: oooh they are observing, yo zuckerberg, change the code!
This actually makes sense if the particle is in a different dimension than us, and when we measure it we are taking a slice of that dimension and basically assigning only that slice to the particle.
This is sorta-kinda like many worlds.
correct, and don't forget particles (before observed) can be in many different states at once.
Very nice and concise video on the subject, with clear explanations and just enough mystery left for viewers to be curious.
I've been exploring this and related phenomenon for over a decade, and still your presentation captures my interest - makes me remember how I felt when I knew about it the first time.
I might follow.
Interesting....thanks for this. There is also the water experiment which consistently shows an interaction between the water molecules and the mind of the observer.
The problem begins with thinking of particles.
That’s interesting, are you loosely suggesting that, since we humans have theorized and done the math to believe they are particles, that’s what the wave ultimately displays…? Because it is a wave of probability after all.. I have thought about this before as well. I wonder if there’s another intelligent specie on another planet who went through a similar process as us, but instead of them theorizing about particles they theorized and did the math for something completely different, and what if that’s what they detect when measuring their versions of “particles”. idk, hope I made enough sense for you to understand me lol.
@@Stampedby__bonetti I wanted to say, that if you go into a theory with preconceptions that are too strong, you always will miss some important traits. So if you are tuned to see particles, you will see particles. It's like looking at clouds with pictures of animals in your head. But the same thing will happen, if you look at the former particles with an idea of probability waves. Both are concepts, that work quite well under certain circumstances. And both will fail under others.
Most people think, physics is about finding out how exactly reality looks like. But the first hard lesson is, that you can't. But you can find out, how reality behaves. The models and theories are made to understand that good enough to make smart predictions. And the analogies, like "photons behave like particles" (IF observed in certain conditions!), are made to get familiar with that stuff.
Let me mention one last point, if you're still sticking to a it"s one or the other idea.
Ask yourself, what a real particle would be like. A solid orb? Made out of what? Which diameter? Homogenious or not?
And how the heck would a complex probability function look like in reality? Etherial Numbers floating in space and time with real and imaginary parts?
So don't ask, what it is, but how it could be described best to make the maths consistent with the measurements.
Sorry to say that, but studying somehow demystifies the whole stuff, and i could have known.
Our world is amazing! The concept that the particles could change when being observed seems like a small change in variables but the consciousness awareness effects it in such a way that had plenty of people stunned! Even to this day people are amazed by this experiment!
@chetsenior7253 let's pretend your English was grammatical; are you saying it's asinine because you yourself was not present for the demonstration of the experiment and therefore how can you know for sure? Or that you can't trust what you seen?! And what's with (...) Are you planning on adding to your thought process or are you using ellipses for some sort of effect? Honestly you may want to revise your comment😪😂💁
BETTER EXPLANATION: "observing" the particle physically **affects** the particle causing the effect.
Thanks Cindy for always doing very interesting subjects that include a mixture of scientific theories explained in a easy-to-understand way. It's a great Channel keep it up!
read some of the replies as they make point on criticism.
I recently spent some time with a certain tribal, farming, backwoods community in India. Lovely, friendly people. And at a communal dinner one evening, I explained the double-slit experiment to the tribal elders. I was astonished at how quickly they grasped and understood the physics and the nature of the experiment and the baffling question that scientists faced. And these were people who had never attended school nor knew the English language. And within an hour, they were discussing among themselves the dual wave and particle properties of photons. They were drawing the diagrams in the dirt! Since that day, I've had a deeper respect for the remote, isolated tribal people of the world.
This sounds fake
Humans are smart. Without school trying to turn us into factory workers, we could be smarter. The key is education. These tribal people were educated and without schools command of obedience, they started thinking.
I often run into this wall with religious people when discussing history. School blinds the mind like a religion. Kids are always asking why until we break them of the habit.
@ Blackwingk... Surely you have met a community of aliens lost in spacetime who were figuring out how to escape from the bondage of simulation into.....?
Why? Because they knew intuitively what someone had to teach you? Lol.

"The mere act of observing"
Mere is doing a lot of rhetorical legwork here to make this seem wooshier than it really is. The instruments which observe the photons do so by *interacting* with them.
"The mere act of interacting with a particle in order to observe it causes it's behavior to change" sounds a lot less spooky, doesn't it ;)
Undestand that the term "observe" in this video means "interfer".
To "observe" the eletron they must use a photon.
Thats why its change from waves to particles

Very informative and makes us curious about physics

What if the universe doesn’t exist unless consciousness exists? Like how in a video game, nothing exists until you, the character you’re playing, observe the environment around you. Our brains are processors. Without a processor, a video game can’t exist. It’s just a bunch of information waiting to be interpreted
Was thinking the same thing, like rendering a videogame.

@@ypxgenuine thanks for the explanation
Was hoping for a bit more in-depth explanation;
Does the method of observation interfere with the light photons?
How was the picture taken?
Does the slits themselves have an effect on the photons?
AT what frequency is the photons fired?
What was that about time having an effect on the experiment ?
I'm no physicist, but I think by now we should have more experiments where the variables are changed to have a better understanding.
There are a ton actually, and the method of observation affecting things is one of the main explanations. After all, observing the universe at that miniscule scale requires special devices and techniques, so the act of observing them itself may introduce external interference from the observer.
Yes, the detector or measuring device used in the double slit experiment interacts with the photon and alters its behavior, causing it to act like a particle. This is because the act of measurement or observation involves the exchange of energy and information between the photon and the measuring device, which disturbs the photon's wavefunction and collapses it.
The type of detector used in the experiment is important. For example, a photon passing through a slit may be absorbed and re-emitted by a detector, which can cause a change in the photon's energy and momentum. This disturbance can alter the photon's path and cause it to behave as a particle, rather than a wave that undergoes interference.
Additionally, the act of measurement introduces uncertainty into the system, which can further disturb the photon's behavior. The position of the photon is uncertain until it is measured, and this uncertainty can propagate through the system and disrupt the interference pattern.
In summary, the presence of a detector or measuring device in the double slit experiment interferes with the photon by altering its wavefunction and introducing uncertainty into the system. These effects cause the photon to behave like a particle rather than a wave, and the interference pattern disappears.
@@sagarjamwal6182I have been intrigued in this topic for years and ironically a guy in a RUclips comment section describes it in the best way I’ve heard.
So in reality, what does the destruction of this wave function mean? Does it really mean that un-observed objects appear differently?
@@DarkSpice84 The wave function of a particle (or more generally a system) contains all the information about the state of that particle. It can be used, for example, to calculate the probability of the particle being in a particular position.
Let’s say you want to know which slit a electron went through without interfering with its current state (that is, you want to make a measurement and not change the wave function, so it keeps the cool wave pattern, as if it was not measured). Measuring some quantum state of a particle is basically applying a transformation to its wave function and reading the output, so you can’t directly measure something out of a particle and expect it to behave like you did nothing.
So the best approach here would be to copy the wave function, perform a measurement on the copy and the original keeps unchanged. Sadly, we can’t do that (search for no-cloning theorem for further clarification).
In short, you have a wave function 𝛙 upon which you can take measurements by applying some transformations to it, but whenever you do so, it changes to another wave function 𝛙’. You may try to clone this wave function, but the best you may get are imperfect copies. I hope this sums it up, cheers.
@@sagarjamwal6182this was AI generated, but good response.
Hi!
For a long time I have wondered what exactly we mean by saying "when the photons are observed" and I encountered this video when I tried to look it up. I'm a chemist and have learned from analytical chemistry that we can't measure anything without it interacting with the material of the detector. I was of course curious in how we exactly can "observe" something halfway through an experiment without fundamentally changing the experiment and therefore likely the result. So when I heard that "scientists used a measuring device to observe the slit that each photon passed through" it obviously peaked my interest. From my understanding, and please correct me if I'm wrong or misinterprets the experiment, the so-called measuring device or slit-detector is actually polarizing filters which do not perform any kind of measurement or detection themselves. By only filtrating forth polarized light from each slit (which I think are perpendicular to each other), it would presumably be possible to identify which photons passed through each slit later on. If this is the case, I think it is an extreme stretch of the definition detector or measuring device if no observations, measurements or analysis were performed by this so-called device. I realise that this is likely an extreme simplification made in order to illustrate other points, and while it is false (at least from my interpretation of what a measuring device is), there might be a valid argument that "we might as well view it as a detector for the sake of simplicity". So there is no magical detector. Darn it, another childhood dream squashed.
I still have some issues with general statements I've encountered such as "the photons change their behaviour because we observe them", which likely are simplifications of "in an experiment in which we tried to observe the path of the photons, they behaved like particles instead of waves". While I don't think either statements are necessarily false, they both seems a bit misleading if left on their own. From my perspective, the experiment when using the filters is, at least to some degree, fundamentally different from the one without filters. We can observe "that perpendicular polarized light behaves like particles instead of waves when passing through the slits", and don't get me wrong, it is definitely a interesting and wierd result that clearly illustrates the wave-partical duality of photons. However, to draw the conclusion/interpretation that "they behave differently **because** we try to observe their paths" sounds rather backwards to me. While it is true that we set up the experiment in order to determine their path, a less misleading way to express the result could be "they behave differently because we fundamentally changed the experimental conditions, i.e. we removed all photons that didn't exhibit certain properties (i.e. a certain polarization)". While this might be obvious for physicists and chemists alike (that we can't measure anything without interacting with it), I don't think it is as obvious to people with other backgrounds. The slit-detector is often breezed over in explanations of the experiment and is therefore more or less implied to be a passive observer. A reasonable explanation for this is that we can't explain everything in a 6 minute video. We would need to explain what polarized light is and why that is significant. Easily understood explanations are without a doubt important, and can be justified even if they oversimplify things (such as the slit-detector). However, when doing an over-simplification and just saying "we just observe the photons" it would be easy, and I think very reasonable, to add a large shining caveat saying "the detector is not a passive observer and that it by its very nature may influence the outcome of the experiment".
While this likely would result in some confusion, it would more importantly raise questions which are the bread-and-butter of curiosity. I genuinely think that Newsthink and physicists in general only have the best intentions in mind, but I find this sort of explanation (without any caveats) unnecessarily misleading nonetheless. While interpretations such as "photons change their behaviours/properties **because** we observe them" are alright to make, I personally find them missing the mark of what the actual experiment was about and what the results really showed (i.e. if I understand things correctly). Is it possible that the photons behaviour changed **because** we tried to observe their path? Yes anything is possible, but I find it rather speculative (to put it mildly) if this is the only data that they base it on.
In general, while it is easy to say "You should stay sceptical even when experts explain something" or "Of course the experiment is more complex than it seems, we're talking about physics and the video is 6 minutes long", I don't think that's something we should expect people from outside the scientific community to always take into consideration. And that is why i wrote this post (also because I wanted to know if I've misunderstood something). I would also be very interested for any information regarding other real experiments (i.e. not thought experiments) that deal with "whether photons behave differently if "observed"".
Have a nice day!
Wow
You're correct about the polarizing filters. Each filter blocks out a certain direction of the wave, x y or z. By combining two different polarizing filters you should be able to block out the x and y directions of the wave, for example, leaving only the z direction. It's true that these filters aren't "measuring" or "observing" anything in the more common way that we understand those words, but I think they do "observe" the light in a more quantum/abstract way than we probably understand. I'm a biologist though so definitely not my field of study.
@@SpencerfromEarth hi, thanks for your response.
It’s good to have confirmation about the filter blocks, so thanks again! After I wrote this comment, I spoke to a physicist friend of mine and thought a bit more about the experiments. Most of my criticism stands about how the concept was described in the video but today I wouldn’t have added the comment about that “I find it very speculative to say that the photons behavior changed because we tried to observe them”. I still find it misleading and very easy to make far-drawn conclusions from it, but I was also a bit too focused on the experiment where many photons were sent in and not the experiment where one photon was sent at a time. There is, as you say, clearly a quantum mechanical phenomenon happening at the filters as shown by the latter experiment. So it’s very likely that it also happened in the first mentioned experiment (where many photons were sent), so it’s not only that polarized light interacts differently than unpolarized light which effected the result. It’s therefore really a question of semantics, and while it could be interesting to delve into a deep philosophical discussion about what “observing” really is, I don’t really think it’s worth it. As I’ve mentioned, I personally don’t like the word *observing* to describe the phenomenon, but I don’t really expect people to care much about my stickler tendencies.
Hope you have a nice day!
wow, I had GPT to make it simpler for me to understand :p
I agree. In fact it's so misleading that you get people coming on the comment section talking about how this proves the universe is conscious... People love a good fairy tale.

That version of the experiment is unsettling.
This is an okay explanation, but not a good conclusion.
My theory:
There's a good chance that we haven't discovered an unknown energy that is Emmitted from every partical and so does from a camera sensor and from electrons
So the camera tries to observe
Electrons and camera sensor's energy entangle and lead the electrons to behave like a partical

How are we still proliferating this misconception? The behavior of particles change when we "observe" them because "observing" something so small means we have to bump something else into it (like the way electron microscopes work).

How do you explain the version of the experiment where they scrambled the results of which way knowledge after the light hit the detector with the “observing mechanism” (polarized filters) operating and in place - and the wave function reestablished every time the scrambler was turned on? The only variable appears to be knowledge in the mind of the observer.
HELP ! There's something I can't get my head around this experiment. How do we know how photons behave when they are not being observed?
One explanation for ordinary light and lightspeed is that light is prismed from a higher dimension. This means where light is can only be measured using probability, explaining why it never follows patterns like a hard, precise object yet is one.
so what does observing/watching actually mean?
to see something you need a photon to reflect from a thing you want to observe and land on the observing device (i.e. eye)
so when you are watching photons, you are hitting the observed photons with another photons - and that just changes the observable photons directions
No
@@straighttalk2069 'No' ? That's it ? That's your answer. Kindly explain if you want to be taken seriously
Yes, for most interactions, but photons do not directly interact. To observe which way, special crystals that split the photon in two can be used so that if the photon travels through one side, one photon can hit the screen and the other can hit a detector. All of these interactions still impart momentum which affect the outcome. MIT OpenCourseware has a great lecture series on this that actually gets into the math but also explain it clearly.
Yours is the first comment I see in this video that challenges the asenine solipsistic rubbish this channel is pushing. Bravo
I dont understand why awareness is ignored by science

I have a theory that this is what Stanly Kubrick was basing his movie on Space Odyssey 2001. The light sequence at the very end as being observed by the pilot (Boman i think) traveling through space after entering a monolith which looks exactly like a slit. The slit is solid black but after he enters he then observes a light show of colors that couldnt have been seen before.
Also , everyone knows how perfect kubrick directed his movie shots are, theres never an error meaning the continuation of the story is never out of sequence, except for 1 time i noticed and this could refer to the delay and observation of a particle correcting itself. The jacket appearing on a chair then disappearing in the next shot was thought to be an error which is unlikely, theres a lost and found alert is being said in the following screenshots, meaning that it corrected itself after the viewers observation.
A majority of the movie is presented with black and white backgrounds (duality) for example the ceiling is made of white light in the U.S. Spaceship just as the floor in Bowmans room is lit up in white light. We see this again in the meeting room ,black ceilings and corners with white light walls. The white light is also in the center of the ship thats rotating with Hal. Im suggesting theres an inside world and an outside world that exist simultaneously but not observable , its seperated by the light. The absense of light is the the monolith, solid black darkness and going through it brings you to the other side. Bowman went through it twice. 1st time as a pilot and 2nd time at his death bed where he becomes a star child made of light.
I cant explain all of it here but i think you can see where im going with this, im very interested to here what you guys think of this.
By watching this video I have understood what I was told a long time ago about life when they tell you you choose your path before you come here
I’ve seen a lot of people saying it’s the physical interaction of the observing device that interferes with the photon, by “bumping” into the photon and causing it to change. To reiterate, if the device is turned off, the photons return to being waves. So once turned on the observing device must be emitting waves or particles that interferes with the photons and causes it to act like a particle.
This makes the most logical sense to me as well. A photon behaving like it “knows” or has “consciousness” seems less likely to me.
So my question is, what if we put more than one observing device in the experiment? For example, one device pointed down (eagle view), another pointed to a horizontal view, and one behind the photon machine. All devices turned on. Would this change the outcome of the pattern the photons make? Would different amount of devices and angles yield different results? I’m not sure if this experiment has been done. I’d love to do it myself but I figure it’ll be difficult to get your hands on a photon shooting machine.
Thoughts?
The quantum eraser, delayed choice experiment disproves your theory.
I’m sure they have tried that and it’s the same….. even you will act differently when observed
Yeah you got point but i think theyve done it with the knowledge they have compared to Us they would be dumb to release such experiment without answering a simple doubt that an ordinary people like Us could imagine.
@@ligerwulf ordinary people simply don't have access to the expensive equipment to test their questions out. Ain't make them more stupid

A non-living photon changing behaviour when observed is more horrifying than horror movies.
A photon being "observed" in this experiment means being detected/measured by a device, which must interact with the photon to "observe"/detect it.
A detection device interacting with the photon is what causes it to behave differently, not someone "looking at it" or "consciousness"

If a detector interferes with the trajectory of the particles, I’m amazed that it manages to marshall them into two relatively neat lines.
Can you imagine how confused they were trying to figure this out?
It doesn’t change when it’s ‘observed’
It ‘changes’ whenever it’s forced into an interaction, that forces an outcome to the probabilistic wave function
We must flip on/off the observer camera like a strobe light and do it faster than the speed of light so that the light particles cannot keep up with the observer camera and be able to react fast enough, then we can see what up. However this might cause the light partical to go backwards as if time is being reveresed. We need mirrors to bounce it back the right direction as the camera is now observing light going backwards in time, i think. lol
Do you remember mirrors reflect light?so electrons would just pass through it too.a reflection is just light bent by the mirror
@tshade Electrons that make the light?. So, what now? It passes through a mirror or something. I dont know lol
Bro!!! 😮😮😮 I'm loving Physics.
Thank you for this excellent presentation. The double slit experiment seems to echo Schrodinger's Cat thought experiment.
Evolution of the Eye Ball begins in the translucent environment , before it discovered the transparent environment. Atmosphere obviously plays on light density and refraction. The slits are shown on a flat stencil against a flat wall representing a stop in space time continuum. I think results would be different if the stencil was curved against an opposite curved wall . Using black paper against black paper is different from using transparent or translucent emulsion against a solid wall .
So, if you did the experiment with 3 slits, would the outer 2 slits cancel the inner slit and make just 2 bright bands? The wave pattern should cancel the inner line.
Isn’t a simulation considered to be a designed creation? (: The Developer really knocked it out of the park with the whole perfect ratio and the Higgs Boson.
Some people believe that the universe we live in has many more dimensions to space, and as the universe has cooled, these dimensions curled tightly around each other. Now to 3D observers, we are convinced there is no more dimensions than 4 to our universe. 3 of space, 1 of time. The ratio these dimensions curled around each other is the golden ratio.
And the Higgs field. Which is an active massive universal field, which all other energies permutate within. The Higgs boson is an exotic particle that was theorized to exist toward the beginning of this universe and which split off into and collapsed into everything else.
Why wouldn't it be the case that spacetime is oscillating, or twitching back and forth while the photon is traveling a more straight path, and it's the location of the slit and the capturing surface that are moving, causing it to appear as if light acts like a wave?

What was the rationale for conducting the double slit experiment in the first place? I mean, did someone correctly hypothesize the results of the double-slit experiment?
They conducted the double slit experiment in order to follow up on the success of the single slit experiment. Next is either the triple slit experiment or the double double slit experiment, depending - then either the double triple slit experiment or the triple double slit experiment, but we should not forget the double single slit experiment.

I think a more subtle explanation can be made thusly; it isn't the measuring device that is causing the observed particle behaviors. It's our observations of the measuring device. Or, more succinctly put, that consciousness itself is what is causing the interpretation. Consciousness IS observation.
I think you're totally right. Somehow, the event of light being a particle or wave and consciousness observing it are linked at a quantum level; existing creates quantum events entangled with light picking a location
That's why time slows down for an observer who approaches the speed of light or is near an extremely massive object (i.e., high gravity)...the universe needs time to process all the information.
Except time doesn't slow down for any observer in his/her own reference frame. Only if you try to observe that person who is approaching the speed of light or is in a high gravity domain do YOU see that person's time slow down.
no matter how often i watch this experiment i will always be stunned be the result. this is so awesome. also it shows that all choices that we make is one out of endless possibilities.
This is the first time i finally understood the double slit experiment in one go.
Particle is like a naughty kid in a room, when not being watched it jumps around the room but when parents come to observe it stands still.😈
This truly is one of the experiments of all time.
I think it's more obvious that there's an error in their equipment than there is in a reality
That's a perfectly reasonable assumption. Unfortunately, it's been proven wrong.
In that picture, Leonardo's gears would've turned both the front set and rear set of wheels inwards towards each other or both sets of wheels outward away from each other causing the tank to remain motionless.
Edit: I swear I didn't see the explanation before writing this.
One of the problems I have with this experiment is that it seems to me that when we are saying it is "observed" with the detectors it causes confusion as it is actually observed al the time but the detectors, the big difference, are actually recording or measuring.
How do you, or a detector, 'observe' a tiny particle without some way interacting with it, and impacting its behavior. In our macro world, we can see a baseball without interfering with it. But when you are trying to detect a single photon or electron, how do you do that without interfering with it in some way?
I still don’t understand. Which slit was the photon emitter pointed at? Was it pointed between them? Nobody ever mentions this when describing the double slit.
I need the answer too.
Wait, they’re saying they performed this experiment ‘one photon’ at a time? Besides it being physically impossible to isolate a single photon, there’s something called the Heisenberg Uncertainty Principle.
I don't think we live in "simulation", but i do think that universe we live in, works similar to a computer program.
it's a FACT that by observing something, you are altering it. or to say it in a different form "you can't observe something without altering it". It's very simple concept, in order to observe something, you must interfere. for example if you are looking at something, then particles interact with your eyes, which is interference.
same happens with cameras. if camera sensor is able to see whatever it is looking at, then that object is also able to detect presence of the camera sensor.
more fascinating thing for me, is fabric of space. we know it exists, because that's what causes gravity. gravity is 4-dimensional. when on earth (or other planets), if you drop something, it will fall towards the core, but in space, if you place something on fabric of space, it will bend inwards, making a 4-dimensaionl "bowl" and things will fall into it.
if you'd be able to get in center of a planet, you'd be in 0g.
so if fabric of space exists, then it means that fabric of space MUST have shape and size. what is that shape and size?
I think it's a cube, because that would make most logical sense and also refers to the theory that it's all a big "simulation".
another interesting thing, is that there MUST be tiniest particles that cannot be destroyed, which act as 1s and 0s, as in binary. if particle exists, it's a 1, if no particle, it's a 0. which means that everything in universe is basically just data, that can be created, copied and/or deleted.
another thing about fabric of space, if it exists (which it does), then it must have particles, but what does it consist of? normal matter don't collide with it, is that what scientists call "dark matter"?
but yes, i too think that universe is more like a computer than "natural".
Simulation is not the word. Synthesis is. If it were simulated, it would be violating physics. It doesn't.
A synthesis doesn't violate physics. It's too perfect to be real, and it's highly statistically improbable, but it doesn't break laws.
The double slit experiment describes the nature of consciousness as an input. As an input, it changes experimental outcomes and directs our actions.
It does, in fact, suggest that there is a God.
Simulation doesn’t mean “violating physics”… synthesis isn’t even a word to describe what’s going on here lmao. Learn what definitions mean. All this suggests is that there is a creator or creators, not necessarily a god.

I don't understand why nobody talks about the physical impact of the observer, obviously is affecting the result and not just watching. For me this is not even a mystery, the observer just somehow radiates or emits something.
This is such a good video explaining a lot of
The real mystery is left out: if the observation is made AFTER the light passed through the slits, ie if observed in the future, the future event changes the behavior of the particles as they go through the slit in the past. Thus, a future event becomes the cause of the past.
I am absolutely sure there are some weird invisible ( to our eyes ) beings all around us laughing at us and causing endless misery for their enjoyment. Everything being recorded as if in some alternate reality. Well maybe not that basic, it's hard to express in words, but I get the impression that most humans get a feeling at one time or another/ or many times, that you are being watched by something unknown. One time when in Europe I accidentally took a large amount of a unknown psychedelic ( long story ) it keep me up for 4 days and I had thought I went mad. During this time a weird world revealed itself to me, there were these red balls like eyes everywhere constantly watching and monitoring every movements we humans make, you know the red eyes in the matrix sentinels, well I was seeing those things literally everywhere all around us, you moved and it followed your movements like a lens in a camera. There were millions of these things everywhere I looked. I hadn't seen the Matrix film back then as this was in 1993 and the Matrix wasn't released until 1999. You have no idea how terrified I was when I saw the film for the first time and those red eyed sentinels were in the film. Its not a coincidence that most people feel weird when looking into camera and asked questions or told to say something..
Those weird invisible beings you speak of are demons. Psychedelics cause humans to see into the spiritual realm. The truth is that demons do watch us, but so do god and his angels. If you believe in Jesus, demons secrets are revealed and they no longer pose a threat.

How observe with the device and watching with our eyes result in different ways since watching is also observing.

What I'm yet to understand is how the experiment measures the interference pattern without counting as 'observing' it.
Literally lol
But you are not observing through which slit the particle is moving. If you don't observe, you get an interference pattern, even though they're firing individual photons through one or the other slit. It's like without observing, the photon/electron doesn't have to give you the information about the slit, sort of like lazy loading in games.
@@dsego84but how do you not observe it? How would you know? If you do not observe it you can’t know. My point is. Whatever is used to observe it is affecting the photon.
I bet this is somehow related to the physical interaction between the observing device and the photon. As a rough example, imagine there is a bowling ball moving on the bowling path, and you throw another bowling ball that should hit the first bowling ball, bounce from it and go back to you to tell you that there was a moving bowling ball, from which your bowling ball bounced. And of course, after the hit not only your bowling ball bounced, but also the initial ball changed it's course. Something like that could be happening on a level of particles, in my assumption. The current explanation that the photons change their abilities because of some conscious spectator sounds like magical thinking, similar to that lightning is being thrown by Zeus etc.
But even still, why would firing individual photons through slits over time produce an interference pattern?
@@dsego84 you believe that part?
Cause without it, the whole thing is just a very well performed ruse.
Think about it.
@@palkys. why not believe experimental results? do you think this is conspiracy? I think you can do the experiment at home, there are videos on yt where people recreate it with a pointer laser.
The "current explanation" as you put it is nonsense. You won't find any actual physicists explaining it that way. Your intuition is correct. There is nothing spooky going on and "observation" is a technical term that basically means "poking the thing to measure it". The "poke" affects the thing being measured. It's really that simple (well, it's not actually that simple, but that's the basic idea).
@@dsego84exactly
That's probably why you can always tell when someone is looking at you
Not proof we are in a simulation. Only that our understanding is incomplete.
What is the device used to "see" which slit the electron passed through? It seems that device is what is interfering with the interference pattern - not us, as implied by this clip.

I STILL THINK THE OBSERVER EFFECTS BASED OFF HOW "SEEING" PHOTONS IS AN INHERENT INTERACTION BETWEEN THE EXPERIMENT AND THE EXPERIMENTER. YOU CANNOT OBSERVE WITHOUT INTERACTING WITH PHOTONS.
Observation of anything, means that you're shooting something at it(waves, photons etc) which if reflected back, you'll see the particle. So in case of photon it must allow other force to bounce back from it.....
The thing that gets me is how the photons create an interference pattern even when shot one at a time.
They're like little magicians 😀
Because they are in whats called a superposition which they are acting like a wave and particle both at once so the particle could be anywhere within said wave
.....finally at the end of the experiment, the photon sued the creepy scientists for invasion of privacy, anxiety , mental trauma and character assassination 😄
Yeah, and then the particle changed gender.
🤣🤣🤗
Perhaps there is an extremely subtle way, unknown to us, of observing photons that does not change their previous condition or behavior, preventing the interference pattern from being replaced by that of particles.
She said it defies our understanding and then explained it perfectly😮
The double slit experiment doesn't say as much about light as it does about consciousness being a physical thing.
No.
A photon being "observed" in this experiment means being detected/measured by a device, which MUST interact with the photon in order to detect/measure it.
A detection/measurement device interacting with a photon is what triggers the change, not someone "looking at it" or "consciousness".
This is ridiculous. It's not the "mere act of observation" that causes the superposition of a quantum particle to collapse. You cannot "merely" observe a quantum particle. You can't just whip out a microscope and have a look. To observe a quantum particle, it must interact with another particle, and it is the interaction, not the observation, that causes the collapse of quantum superpositions.
Exactly. She doesn't know anything about videogames either. They are not related in any way, a game is predetermined from the start, bound by rules even if its random. It culls objects out of view because its a waste of time drawing them, but they are there. The wave function algorithim itself follows rules based off the input. You cannot predict where a photon will hit, only the probability.
Nope. Based on experiments, even if the observation is done AFTER the photon has passed either of the slits, the photons will still behave as particles. With no observation, the photon will behave as a wave.
@@jkturtle So the observation retroactively changes the photon from wave to particle, so it's time traveling?
@@josemonge4604 yes. And it's wild.
You are wrong. Clever people managed to do it without direct interaction long ago.
Right On
This phenomenon is similar to the how we see the universe as well. It appears objects are moving away from us faster with distance gained yet the messuments as to the speed this is happening is skewed depending on which method is used to record the data know as the hubble tension. This fits perfectly with how light behaves when being observed. Its like it is programed to behave different ways if its being watched. I wonder who wrote the program.
This test needs to be conducted with several animal observers. If this effect is only observed whether or not a person views it, or whether a person has the potential to view it via a camera. This would prove that humanity is of a higher priority in existence and would suggest that there is a deeper meaning behind this experiment.
Could the speed of light limit be the result of the “clock speed” of the simulation for updating the position of particles in addition to determining their observed state?
I am a programmer and I thought about the idea, that the world might be programmed a lot. From this perspective the idea, that light behaves like a function whenever not observed closely seems like a typical optimisation. Why simulate a myriad of photons, when you really only need a macroscopic light/shadow texture.
I have many ideas about time, but it is very hard to order them. Time goes slower in proximity to large masses and obviously where there is a large mass there is a lot of matter and where there is a lot of matter a lot is happening and where a lot is happening a lot has to be computed - so it makes sense that the program needs a lot of time to calculate each frame in these regions and therefore time in these regions runs slower. This is obviously not a commonly used programming strategy since in basically all programs time is a global variable and not depending on space or anything else. Time also goes slower when moving very fast and this makes sense since an object that moves very fast potentially experiences a lot of different things in a very short time, which again is computationally expensive.
In the end I really can't wrap my head around all this though. It is an intriguing idea at the least and I'd really like to explore these topics deeper and gain a real understanding of it all.
I don't really understand how you want to connect the clock speed and the speed of light though?! It could definitely have something to do with it, but why would these two things be dependent?

Can someone do this experiment with 100 different ways of looking…. E.g. different distances, using a mirror, a quick peak, using a telescope to look, looking through filters, and loads of weird ways to observe. This would be very interesting.
There is no way to guarantee one photon being released in a double slit test. What you are seeing is multiple photons being released in a stream. Because the distance is so short that they travel, and since they are traveling at the speed of light, it appears that they are reaching their destination simultaneously. This is creating bands of light as two or more particles' wave formation is colliding. As for the last version of this test with multiple lasers on a reflective surface, the reflected photons are combining their waveforms with the photons not being reflected. This is creating harmonic waves that can be seen as different colors of light, just like in sound waves colliding.
Particles change their behavior when observed because of consciousness. When the consciousness of an observer connects to the consciousness of a particle there is an energetic and magnetic-like reaction. Much like blowing wind on a leaf, although that is still more random. Many of the big brains out there still have a problem with grasping the concept of consciousness related impact.

Consciousness/a human directly "observing" the photons doesn't play a role in the experiment, regardless of what you believe. The only reason to think that it does is if you misunderstood what the term "observer" as used in the experiment is referring to.
