Transcript:
You've heard about quantum entangled particles?
Yes.
Where I can create a pair of particles that know about one another and that they're separated in space and in time.
And if you observe that other particle,
it instantly changes the state of the particle back.
The other particle that's back where I am.
And by the way, they communicate instantaneously,
faster than the speed of light.
When you say if you observe...
but you have to do something.
You have to do. You have to. Yes. So something has to interact with. It's not woo.
The problem is the word observed people thinks is a is a psychological thing.
But in physics, it's got nothing to do with...
It's a measurement. It's a measurement thing. Right. And so, in other words, if we're measuring if there's a if there is an electron sitting in the middle of this table and all the lights are out, I can say I think there's an electron here. Let me find out. And the moment I turn on the lights, the light interacts, a photon interacts with the electron and kicks it somewhere else. So the more I try to measure its position, the less I know its position.
Ooh!

Sometimes in the morning i like to drink coffee while i watch neil talk and i pretend like i understand it.
I too like to drink and listen to Neil but it's more of an adult beverage.
Photons from a light pushing an electron off a table is pretty easy to imagine. Imagine the light as a laser and the the electron as a balloon.

DeGrass Tyson- “You heard about quantum entangled particles?” Rogan -“Yeah.” LOL
It would’ve been hilarious if Neil asked Joe to explain it to his audience
I don't think of myself as a smart dude or anything and I've heard of it bro 😁
Might've been from Ant Man lol
@@blobbydigital5610 no 🤣
yeah, from his last dmt trip
I like how Neil gave a simplified example for Heisenberg's uncertainty principle without actually saying it's the Heisenberg's uncertainty principle.
Well, it’s actually more than just that🤷
Right? I can't explain any better but Neil's explanation sounded very simplified to me.
Not only that, he kinda explained all three interrelated theories of the Uncertainty Principle, Copenhagen Interpretation & Schrodinger's cat. All three of them are based on uncertainty.
because it isn’t heisenberg’s uncertainty principle.

Exactly! In quantum physics, measurement is no longer passive action, it's an active action that can and will effect the particle you're looking at
Kinda similar to reading blood pressure they know for a fact that unless you have a massive amount of self control just them doing a reading changes your BP.
Dirac's Equation or The Love Equation
The concept contained in the equation is that: “If two systems interact with each other for a certain period of time and are then separated, they can no longer be defined as two distinct systems, but become a single system.”
THANK YOU, THANK YOU SOOOO MUCH!!!
For so many years I've been having to listen to assholes like Michio Kaku try to spin some relevance into their pathetic lifes by making it seem like science has elements of mysticism or magic. It doesn't....... whats more, it doesn't have to, this stunningly amazing universe that we're lucky enough to find ourselves in is beautiful enough all by herself
Is it called the love equation because whenever you meet someone, your destinies are forever intertwined with each other?
This is false. Why do you say random stuff in the internet?
Y'all sound smart and I'm not. I want to ask a question might be silly but I want to know lol. If I can turn the direction of one electron and the other one instantly changes, wouldn't that be like unlimited energy? If I get the output of 2 turning when I only put in the energy it takes to turn one, doesn't that violate that thermodynamic law where I can't get out more than I put in? If that's wrong (I'm sure it is lol) I would like to know how

Cool
Well it’s not really observing, if you were to try & take a measurement so that you can observe it, it changes its state immediately so that you would actually be observing something entirely different than what you intended to observe.
@@calicoesblue4703it’s called the “observation theory”

The game of hide and seek. Most choose to seek rather than hide. Just like the game, you have to want to be found. This is the principle of manifestation.
Sounds like the Tao....always infringeing upon religion is this guy
So you’ll find it where you least expect it, just don’t go looking for it.
It's because it's connected in the 4th spatial dimension. So it can travel faster than light because it exists at all points of time at the same time. It's hard to comprehend because it is entirely outside our ability to perceive it.
"Entirely out of our capability" pfftsh speak for yourself
"Its not 'woo'" summarizes Joe Rogans process of thought perfectly
No
Hahahahha
In another instance, he would say... Boo!
😂😂😂😂 I didn't get it til you said it... And seen that movie like 6 times... Smh 🤦🏾♂️ and hilllllarrrious
Haha!
That's a great and simple way to explain why it's so hard to "see" certain particles
That is also Heisenberg's uncertainty principle, in case anyone wants more detail on it
“The problem is that people think the word observe is a psychological thing. But in physics, it’s a measurement”
Yeah, that’s because scientists picked the wrong word to describe what they mean. If everyone thinks your word means something, it does.
This is why, every time we remember something it will be different than how we remembered it last.
Well probably not but it’s a really interesting idea.
Heh
😂
The best discription of the Heisenberg's uncertainty principle I've ever heard.
People who do not know anything about quantum mechanics/ physics/ chemistry, they think if "observe" as "to see something". The problem with that is, these particles are way to small for us to see them, so we prove their existence by interacting with them, and since we can interact with them, they must exist and from that interaction we can gain information about for example their size, "charge", speed OR position. That is an "observation" and the reason why, whenever we try to observe quantum mechanical particles such as electrons, they become more and more difficult to describe "unscharf" (ger.). By observing them, we make the informaiton we gained a thing of the past, since its already changed because we observed it.
this is the best i can do without going into qm-theory and in english
Whenever I tried to approach my crush, I just couldn't. So that's quantum mechanics!
The reaction was gold🤣
I now know what “observe” means. It’s all makes sense now.
🤣🤣🤣
Quantum entangled particles are important for space travel because they allow for instant communication over any distance. They would be amazing for online gaming as well with almost no latency
Imagine being so weak you're knocked out by a photon.
Jimmy pull up a picture of electron diets
@@lysandertavish1684 Electron 'bout to get some massive quark gains
LOL perfectly describes leftists these days . . .
These are eventually going to enable instantaneous communication across stellar distances. We just have to learn more.
Yup 100%.
Amazing! That was my thought while he was speaking. Instant, interference-free communication across vast distances.
Nah, we just have to not go extinct first. Until oil and gas industries are gone and billionaires and governments stop starving us to d3ath en masse, there's very clearly no point in tackling a currently non-existent problem.
Yeah. But quantum physics is very subtle, and nonlocal in functioning. We’ll have to design tech for manipulating bits of energy in superposition.
Me looking for something I was holding 2 seconds ago
You've heard of quantum entangled particles? Joe Rogan: YES
Rather uncertainly principled, though.
Einstien: Light has no mass
Quantum physics: Hold my electron.
The beauty of quantum entanglement is that some particles become linked somehow, and we may not know it or be able to see it, but they communicate and affect each other. We are made of particles and so we are all linked, somehow, and sometimes we feel unexplainably attracted to a place, or a person or a thing.
I believe that scientists are able to use this effect to instantly communicate information. For instance a receiver on Mars or even on a space ship thousands of light years away can provide instant communication.
All you said is wrong, I'm sorry
I think it's more accurate to think of quantum entanglement as 2 particles becoming one or behaving as one instead of becoming 2 particles that are linked to eachother but remain separate. It is known as quantum nonlocality I believe
@@alessandroc.4543 don’t be sorry. I’m glad to be proven wrong, as I can learn from it and grow. As I came back to this I laughed at myself
Adds new meaning to, “sending thoughts and prayers your way.”
He's describing Santa Claus in quantum lingo
I believe if we can fully flesh out our understanding of quantum entanglement we will be able to teleport instantly across the cosmos with no time loss and communications will have no range limit.
That makes sense 🤔
@murphy just because you dont understand doesn't mean it doesn't make sense
@murphy I understand how it doesn't make sense.
Finally someone who explained it well. It’s about the delicate interaction between elementary particles. It’s the measurement. By doing a measurement you adding energy to the experiment. Not the misleading word “observer”, that lead someone to think about the human mind influence/consciousness.
Bro the act of measurement is literally the act of observance. You cannot measure without observing. And who is measuring?? The human consciousness- AN OBSERVER. How are these two concepts so difficult to grasp in their unity is so mind boggling to me. People will doANYTHINg to separate spirituality of our consciousness with scientific quest that they forget the entire universe is first and foremost spiritual. It is literally magic. Have you seen how crazy it is up there? How did we even get here? Why are we here? The very question of the “why” is phenomenally magical. If you can’t unify the two then you are looking at one side of the coin and calling it the only side when you KNOW coins have two sides.
Measurement IS observation. You CANNOT measure without looking at the damn thing first. Looking at it and expecting some kind of probable outcome IS the act of trying to measure it. Switching on the light in the room to see where tf the election is, IS observing it. You cannot observe in the dark can you? The only way to observe is to LOOK AT IT. You can only look at it when you create some circumstance like switching on the light to observe it.
I love the moments when my deep brain goes oh yeah I get it, and then the other 99% of my brain goes w*f did he just say
Yep
He mixed entangled particles with Heisenberg uncertainty principle, which has NOTHING to do on how to measure the position. It has to do with the intrinsic impossibility to measure anything with 100% certainty ( the operation is not commutative). Not because of the instruments, but due to a natural limit.
I feel like soul mates are quantum entanglement. There’s an indescribable bond that you cannot explain.
Yes!
There is no souls LOL 🤣👌

As a kid I perfected my hide n seek strategy from an electron
No. It doesn't change. You just know the state of particle a, when you know the state of particle b.. That's a big difference
I just wanted to know if you saw where I left my keys, Neil..
For those wondering.
When you are about to call someone and they call you first?
When you're thinking of someone randomly and they all of a sudden contact you?
Some people believe that is quantum entanglement, or 'soul mate'. Eternally connected and one directly effecting the other.
Thank you for the explanation/translation ❤️
Ya, but guys like Neal won't be talking about that for a long time.
I feel so many never apply their theories to their lived reality. "It's just a coincidence if it's outside the lab" kinda cognitive dissonance
Firstly: the particles have had to interact with each other first , then can be separated by any distance, supposedly! Secondly: when you do observe (take readings of) one of the particles, it's 'entangled partner', wherever it may be, surely would be opposite!
Particles have what we call states....and what state or it's character such as spin, charge...so when you measure or observe one, and it has say an upspin position the other one surely will be downspin. So it's not like the particles are communicating as such, it's just that one will be opposite to what the other one will be.
Then goes on to speak of particles being somewhere then when observed they move or disappear 🙄...he's talking about not being able to pinpoint exactly where every particle is in the famous double slit experiment (can look it up) and instead it's only the most probable area percentage of where it may land....and turns out it does a wave function...so that's how we know they can be both a particle and a wave at the same time. 😉
I agree with your first point. I too am unable to understand what's so fascinating about quantum entanglement. Can it not be that the information is stored in the particles when they first interact and later on, when you read one, you know the state of the other.
Secondly, I think he suddenly switched to hiesenberg's uncertainty principle about measuring the position or the momentum of a particle. I dont know how or why that information was necessary for explaining quantum entanglement.
@@huzaifasajid6830 i think he mentioned the uncertainty principle in order to really demonstrate how unpredictable and random these things are. Making the fact we can know the state of entangled particles across theoretically ∞ distance that much more shocking and interesting.
I like the explanation, only thing I’d suggest to add is throw in the term superposition when mentioning the initial interaction between particles.
@@huzaifasajid6830 yeah it was a bit mixed up. Niel is a nice guy and he has some insight but I just don't quite know what his main field of expertise is...think it's astronomy...but I do get a bit confused with some of his explanations ...or he isn't sure but continues on. Either way some specialists in the field of particles and quantum physics always say, once you think you understand it, you don't know quantum physics 😄...which I think is so true.
He just explained humanity...to put it bluntly.
I heard about this a while back. I am totally freaked out by this.
A good way to imagine it (i believe i read it in one of brian greene’s books) is:
Let’s say you try to observe a fly, first you attempt to measure it’s position in your room. The more precisely you know it’s position, for example with an extremely good camera, the more the fly will look static. You know the exact position, but it seems not to move, therefore you cannot know it’s speed at the same time. It looks frozen = 0 speed.
Now you do another observation, focusing on it’s speed. The more accurately you measure it’s speed, the less you can tell where it actually is since everything around it will be blurry.
That’s one way to explain this principle, hope it helps :)
@@lunahri4173 - thanks for the explanation. It is not that I don't get it at a fundamental level. The mechanism through how particles become entangled, i can't begin to fathom. What weirds me out is how two particles connect by what ever force allows the spin, they can be separated by space and time and still subject to the effects on each other. Totally weird. The theory as I understand it predicts that the entanglement is instantaneous through space time, right? So this force isn't just faster than light, it is infinitely faster than light. Like a particles can reach 13 billion years into the future or across 13 billion light-years of space to affect the spin of its entangled partner. What is up with that?
This kinda explains dreams for me.. my whole life I've had very vivid and crazy dreams and I forget some but so many I can remember vivid details even when they make no sense to my mind when I wake up but in the dream I'm reasoning between two trains of thought...one with more feelings (in the dream) and one in more logic (being conscious)...I have a lot of dreams where they feel like they are in a different space and time kinda... sometimes in an ancient future... sometimes in alternate past or realms that sometimes go back and forth with one another, because the world and people there understand time space and existence...and I'm just stuck there witnessing it just like I am here even if I can control some aspects there is still some kinds of laws ...but always different somehow.. in some dreams im telling my brother I feel like I came back in time in a different timeline through my dreams and he's like the only who understands that ..there and here ...he's open minded like I am but dreams I think are part of an observation point... Then when you dream you are measuring those particles in another space and time... That's what just hit me when I heard this..maybe other chemicals in the body and spiritual chemicals folks use also do the same... 🤔 Who really knows for sure ...? Some things you can just feel even when they make hardly any sense..not to say it's wrong just to say it feels right instead of the other way around...I'm learning that feeling doesn't always make things real in an actuality standpoint but it helps motivate an individual nonetheless... Lol 😂🤷🏽♂️🙆🏽♂️🙅🏽♂️..who else has super wicked dreams that have stuck with them and become actual memories you remember when you woke up and still can remember..wether it was today yesterday ten years ago... I'm obsessed with dreams and how you can recognize people you've never met... Maybe we connect that way too it's insane to think cuz it's limitless in idea... ✌🏽😎😴😪🤤💤
thats literally your left and right brain talking/clashing... ADHD helps make overactive brains.
@@cyber1ifeconnor interesting theory, but don’t act like it’s fact. Good guess lol
@@cyber1ifeconnorOveractive or under-stimulated? Our ancestors used to have the time to study the stars so hard we can now predict their movements with to-the-minute accuracy. We had time to think up machines so sophisticated we don't even understand how they work anymore with all our tech of today, to hyperfocus so hard we built multiple astrological systems with nothing but the stars and some hand tools. We're under-stimulated. Nay, under-thebootofcapitalism.
I'm most thoroughly impressed by the fact that Joe was able to not only interrupt NDT, but get him to acknowledge this was a conversation.
What crazy is that they teach this in class 11 it's Heisenberg Uncertainty principle well not quantum entanglement but the electron part
No that's not the uncertainty principle, he just made it up.
Man i was searching for this comment, i laughed so hard when he said yes so instantly
Tyson just barely understands any of this.
The instantaneous communication is what bothered Einstein, and is still debated to this day.
"The electron knows where it is at all times. It knows this because it knows where it isn't. By colliding with a photon, or not colliding with a photon, whichever seems to happen, it obtains a difference or deviation."
I thought they were gonna bring will Smith in
Wow you actually heard the word entangled and associated it with Will Smith....So you watch TV...You failed at humor and in life.
Tyson startin one topic, ending in another... I luv token scientists
But he didn't?
@@thename5069 Exactly
He talks about this as if it's a thing. "I can create a pair of particles that know about one another, separated by space and time..."
It's a theory. That cannot be measured... therefore not observed.
And yet it has been measured, and therefore observed.
Measurement is a psychological thing because it is the act of being consciously aware of a quantity
Well it’s like some humans on TV. You know the camera crew is here so you act nicer, dress better and smile brighter.
My brain trying to understand this: 🥴🥴🥴
Heisenbergs uncertainty principle is a fundamental problem with measuring. We currently cannot measure subatomic particles without altering the state of the particle.
Guys something's wrong here, he's basically saying electrons are kicked away by photons when we switch light on that's why we're unable to measure.
But it also means that always electrons are kicked away by light even if no one's measuring it.
So no measurement is needed
Someone explain to me if I'm wrong
“You’ve heard of quantum entangled particles?”
“Yeah”
You big fat liar Joe Rogan.
He’s a grown ass man who has really smart individuals on his podcast nearly daily. It’s not surprising he’s heard of them at all.
Yeah but I wish a real physicist would communicate instead of popularise stuff. As a physicist I want public to know how beautiful this is but not everything is entanglement and “black holes”.
As much as I love Scientific pursuits, I can't take Quantum Entanglement seriously.
How can nobody here is mind-blown by the fact that a particle can affect another particle separated by space and time. That's sci-fi stuff, almost paranormal stuff being discovered.
They don’t communicate, they are part of the same system
“You’ve heard of quantum entangled particles?”
Joe Rogan:………..Yes
This reminds me of the double slit experiment
Saying that it communicated is somewhat wrong. Instead it’s that both particles already have a state when together and retain that state when separated. This is why you couldn’t use this for FTL communication
I learned about quantum entanglement from Mass Effect 2.
This is the story of Orpheus and Eurydice. Apollo gave his son Orpheus a lyre and taught him how to play. It had been said that "nothing could resist Orpheus's beautiful melodies, neither enemies nor beasts." Orpheus fell in love with Eurydice, a woman of beauty and grace, whom he married and lived with happily for a short time. However, when Hymen was called to bless the marriage, he predicted that their perfection was not meant to last.
A short time after this prophecy, Eurydice was wandering in the forest with the Nymphs. In some versions of the story, the shepherd Aristaeus saw her, and beguiled by her beauty, made advances towards her and began to chase her. Other versions of the story relate that Eurydice was merely dancing with the Nymphs. While fleeing or dancing, she was bitten by a snake and died instantly. Orpheus sung his grief with his lyre and managed to move everything, living or not, in the world; both humans and gods learnt about his sorrow and grief.
At some point, Orpheus decided to descend to Hades to see his wife. Any other mortal would have died, but Orpheus, being protected by the gods, went to Hades and arrived at the Stygian realm, passing by ghosts and souls of people unknown. He also managed to attract Cerberus, the three-headed dog, with a liking for his music. He presented himself in front of the god of the Greek underworld, Hades and his wife, Persephone.
Orpheus played his lyre, attracting Hades. Hades told Orpheus that he could take Eurydice back with him but under one condition: she would have to follow behind him while walking out from the caves of the underworld, and he could not turn to look at her as they walked.
Thinking it a simple task for a patient man like himself, Orpheus was delighted; he thanked the gods and left to ascend back into the living world. Unable to hear Eurydice's footsteps, however, he began to fear the gods had fooled him. Eurydice might have been behind him, but as a shade, having to come back into the light to become a full woman again. Only a few feet away from the exit, Orpheus lost his faith and turned to see Eurydice behind him, sending her back to be trapped with Hades forever.
Wow interesting
First, the Heisenberg uncertainty principle: You are in the dark, in the basement. Concrete floor. Empty except for one billiard ball somewhere on the floor. You have to find the billiard ball's location. You can't turn on the lights. Your only method of detection is to roll another billiard on the floor and listen for a collision with the original ball. IF you hear a collision, you know where the original ball WAS located, but now it has a new speed and direction, and a new location. You can't know BOTH a particle's position, AND momentum at the same time.
Second. The entanglement part means that if you change the spin of one electron in a pair, the other electron will change instantaneously; even is they are thousands of miles apart. The information that makes them change spin "travels" instantaneously--faster than light can travel.
How do they know it interacts with the other particle because they would have to observe the other particle which has then changed its state because it’s been measured
NGY: "You've heard about quantum entengled particles"
Joe Rogan: "Yes 🧐"
He is talking about Heisenberg Uncertainity Principle in later half of this video. When I read it in my high school physics book, I was surprised how little we are in control of the task of "observing a little electron accurately and realistically". We affect the events or objects around us at the mere act of observation at microscopic level. We can never observe the particle without affecting it.
Observation = interaction. Not just merely looking at it with our eyes as conscious observers.
@@vanillaglue Where did I say it's not?
This seems like an impossible thing to observe based on everything he said.
Entangled particles can be separated by space, but they aren't separated by time, NDT is wrong.
They are in the same time, otherwise they wouldn't be entangled, entanglement is by definition a simultaneous relationship.
That's why you've gotta measure where it isn't to know where it is. Missile logic
Lol
It’s hypothetical.There’s no way you can measure one to know the other in light years away instantaneously.
I think at best two entangled particles having super synchronization. So you measure one, you can assume the other instantaneously, because there are SYNCHRONIZED not ENTANGLED.
There is no mechanism that one particle can control the other, and vice versa.
It's the same as the instant i understand is simultaneously instantaneously when I don't.
I think entanglement is a primary feature of quantum mechanics not present in classical mechanics the particles are spinning both directions and the act of observing it changes its current state
I am no scientist but their is logic. If becoming aware of a particle alters it that would at a minimum imply a connection between those particles. Which implies we are probably more connected then we’d like to Imagine.
Hey,I actually get the idea now. This is the best I've heard it explained
That ooh at the end. 😆
"Jamie, pull up that video of the quantum entangled bears'''"
That last bit though!
This is literally just Heisenberg's principle where you can at a time only know for certain a particle's momentum or position. It can't both be determined for the same instant of time.
The video felt incomplete. He was explaining Heisenberg's uncertainty principle.
That particle Was here just now
Heisenberg uncertainty at the end
