TRUE FACTS ! 📽 📸 people definitely behave differently when they know they're being filmed [even security surveillance has proven that fact 😅] I'm a Photographer & Videographer, mainly been doing Event Photography at raves for the past 14 years, and because of the fact that people act differently when in front of a camera, I became a "self-proclaimed Master" of Candid Photography !

This have me some Stanley Parable vibes

Simple. All particles and all matter exist as a waveform before the fact of observation by a human. The fact of observation makes it a particle. Animals can not do it, by the way. It's been tried, actually.

@@sd789sd so... whoever is observing has to be aware that they are observing, and that they are observing the way the light will react? Like, what about say... a 3 yr old child that doesnt know what they're supposed to do?

@@SeeMeRolling Nope. It is a fact of observation itself. Has to be a human though. 3 years old will do if we somehow make 3 years old interested enough to watch. )) it is our attention that manifests energy as matter. If you serious, there are couple books you can read. )

@@sd789sd sir, what are those books?

@@sd789sd But what about animals that have the intelligence of a 5 year old human? Perhaps a crow, or an elephant?

Simulation

Yup. Like measurement error.

Yes! That's exactly how I often feel.

@@carpathianhermit7228 Oh, that's kind of theory that can explain everything without explaining anything. How would "simulation" solve the fact that the first pair of photons end up being polarized because their counterparts are polarized, which prevents interference? No, of course, we can speculate, that there's probably an algorithm that calculates the universe infinite time ahead on each step of Plank's time for each particle, but don't you think it's too much to ask?

the secret is ... if science can not measure it, they say it does not exist. This experiment prove sciences = scienctism.

Charles Uwakwe lol just noticed the puppy 🐶 ^.^

Ok... But how you explain the experiment at 8.41 with two detectors A and B that can be far away but you will always obtain no interference pattern in the screen if they are on. Seems like information goes back in time.

So when do we get to read your entire paper? And surely you have a theory on how to prove this without variables with the act of the observation removed? Let me know please. I think you may be on to something.🇺🇸💪🇺🇦🖕🇷🇺

Yes in the delayed choice quantum eraser the particles that had their information scrambled did not collapse

@Svenson c+d did get an interference pattern due to their path not being measured. That's what was explained.

There is no "collapse" in quantum mechanics.

Sadly, he got it wrong, so you are pointing people to bad information. The pattern on the screen does NOT change depending on what happens to the entangled partner. Their states are entangled and you can see correlation when you measure everything later, but it doesn't work like he described here.

It is not actually accurate. There's an element missing. Look up The Delayed Choice Quantum Eraser Debunked by Sabine Hossenfelder video. She explains the wave patterns from each side when combined produces the full scattering appearance because they're slightly apart. The "no interference pattern" is actually two interference patterns combined together, slightly offset, to produce a full field. That's something Joe and many others missed.

Finemann actually suggest once that there might be only one photon in existance going back and forth through time. Turned out to be wrong but still... :)

Or in quantum world the time itself is subject to tunnel effect / is quantizied.

Unfortunately it still sounds crazy to tell people that you experience/sense time non-linearly.

Problem is, the delayed choice quantum eraser should work in this way also if You consider quantum particles with mass and that therefore actually "experience" time...

I'm not sure but this might have been tested with other particles like electrons too. I think it applies to any particles in a superposition and entangled state. Electrons, protons and atoms certainly don't travel at the speed of light so they do experience time in the traditional sense. So in theory, anything in a superposition would experience this bizarre effect, even macroscopic objects, assuming you can set them into a superposition.

that sums up joe :)

That means you understand it I think

I think I understand what he was saying....that doesn't mean what he said made any sense....quantum physics is *WEIRD.*

"if you think you understand quantum mechanics, you don't understand quantum mechanics"

That traveling back in time is my favorite!

Hey, that makes about as much sense as any of the leading explanations 🤷‍♂️

Actually very reasonable. Only calculate collapse wave functions when they matter, otherwise just use the mean value of stuff.

Can you explain that a lil bit

The simulation answer is a non-answer.

I think you are absolutely correct. Only render it when someone is focused on it, otherwise just use an approximation and you can cut down on the computation load.

Because of Joe?

I don't see a question there. It's a little difficult to answer a question that hasn't been asked. Both Relativity and Quantum Mechanics require that in order to exist, an object must interact with the universe. It must engage in one or more of the four fundamental physical interactions: Strong Nuclear Force, Weal Nuclear Force, EM, and Gravity, or it just is not real. An object comes into existence when it is realized, for example, in a Hawking interaction at the event horizon of a black hole. Let's think of perspective, for a moment. We are creatures of electrons and mass, so to us the universe, although quite sparse, is alive with gravity, chemistry, and light. Consider the perspective of a Neutrino, though. To it, Gravity is almost non-existent. It only feels the effects of Gravity to any noticeable affect near a Neutron Star or Black Hole. Light doesn't exist at all, and we humans, even the entire Earth are so ghostly as to be almost imaginary phantoms. Stars are a bit like fluffy clouds: definitely there and not totally insubstantial, but more like a low density foam than a massive object. Our aforementioned friends the Neutron Stars are definitely quite solid, and while a black hole probably can't tear a Neutrino apart the way it can a human body, or even an atom, it is still a daunting object. To exist, then, is to be affected by some force. A force, however, is taken to be an exchange of Gauge Bosons. When one charged particle passes another, its path is altered by their electric and magnetic field interactions, mediated by virtual photons. We can infer the position and momentum of the charged particle by observing the particle's effect on the other particles near it. In doing so, however, we alter the very things we wish to measure, since the object not only affects the test particles, but the test particles also affect the object in question. In this scenario, we are not observing the object directly, but rather through its affect on other objects. The point is, whether the interaction we observe is direct or indirect, the fact the object exists means it not only affects the universe, but it is also affected by the universe at each and every interaction. The fact is there is no such thing as a direct observation, but If we want to observe the object a bit more directly than inferring its properties from the effects on the rest of the universe, we can employ a real Vector Boson, rather than a virtual one. (We can, of course, also employ collisions with non-gauge particles, but we can set that aside for now.) Any Vector Boson might be employed, depending upon the nature of the object, but let's just talk about light. If we want to know the position of a particle, we can send out a barrage of photons and see which one bounces back, pinpointing the particle. That, or if the particle is self-luminescent, we can just wait for it to emit a photon, and see from where the photon came. There are two problems, however. The first is the photon has a finite spatial extent quantified by its wavelength. We can only pinpoint the particle's position at the time it emitted / reflected the photon with an accuracy no better than the wavelength of the photon. If the photon has a wavelength of 1000nm, then we only know the position of the particle to within 1000nm. In order to nail down the particle's position better than that, we must employ a photon of shorter wavelength. Practical matters may intervene, but theoretically there is no finite limit to how accurately we can measure the position of the particle. That brings up the second problem. Even if the particle was at rest when it emitted / reflected the photon, it isn't any longer. By conservation of momentum, we know the particle's momentum must change after interacting with the photon. What's more, the amount of change in momentum depends upon the momentum of the photon. The greater the momentum of the photon, the greater the change in the particle's momentum. Since the particle's position cannot be known precisely, this also means the momentum cannot be known precisely. Furthermore, the shorter the wavelength of the photon, the greater the uncertainty of the momentum of the particle. This leads directly to the Heisenberg Uncertainty Principle, but the point here is the observational limits are not just an empirical hardship, but are in fact the fundamental nature of the universe, and of space-time itself. In the very deepest sense, reality *IS* observation.

Thank you for this comment. I was confused. By "observe", I thought he meant "to look", but the sensors were actually interacting with the beam of light in order to measure it. Now, it makes sense that it would behave differently under "observation".

Interference while measurement doesn’t explain or account for the strange behavior that occurs during the experiments that measure and then “forget” the measurements. Though measured and interfered with, the light particles somehow reacquire superposition, which is plain nuts.

if an entangled particle can affect the other instantly through space it makes sense it can do it through time - time is another dimension much like space, we just seem to be moving at c through it.

It erased my brain

Joe should create a separate video for this

But were they in your pants before you threw them up?

Not a smart guy here, but I think since splitting the entangled particles failed they had to split it a couples more to change the point of origin. Splitting one entangled particle will not technically separate them as they act like they share the same WiFi signal. But detecting half of the particle on the measuring device does not give them any new result since the other half is still reacting no different. Kind of like someone pretending to be 2 different people on 4chan but in the end they're just using the same ip address and you can see that. So why not he use his computer with his WiFi. Pull out his tablet and pair it with his neighbors WiFi and then on top of that use his phone with its mobile data. It looks like multiple people are sh!t posting but little do I know, it's all synced up to one device. I would not know that so I would go on arguing with 3 people not ever knowing its just one.

The act of meeting one neighbor automatically makes the other neighbor a stranger. Stranger is RIGHT!

Not even that... just the moment to moment subjective experience of thinking you're in a real world.

@@etahydri That's assuming that subjective experience CAN be "rendered". Maybe it's not possible to simulate consciousness, or it's extremely hard to do so. Anyway even if possible, this would still be prohibitively expensive to compute.. I mean, to simulate a single experience of a human in 2019 you would have to go through the evolution of the whole observable universe up until that point. So what would be the difference from the "real thing"? None.

Well, and the spawn chunks

THE DOUCHEBAG Funny cuz it’s true. True that some people actually believe that! 😂

@@crownspecialties there's absolutely no way to prove or disprove it without the "aliens" actually interfering from outside. I'm not sure why you find it laughable. You have no evidence to disprove it, and that fact should make it a little humbling. What if the Bible (Either Hebrew scriptures or New Testament, take your pick) might be about beings coming to interfere in our simulation. Almost any religion can be re-interpreted this way. Think about it.

Cuvtixo D Believe in any crazy thing besides the obvious, that we and the universe were created by god. Of course I can’t disprove aliens and I never said they don’t exist. If Aliens do exist on some other planet who started saying that they were the ones that created us, that’s so far-fetched. And why do we need to live in a computer simulation, this is real life you’re talking about a movie. We have zero proof that Aliens exist and tons and tons of proof beyond common sense that we were created by something intelligent. We have the Bible!! The Word of God. We are a design. This universe is a design. It didn’t just happen accidentally. Something intelligent planned this out then meet us. And that something is the God of the Bible. But most people don’t like what the Bible says most people just want to be their own guards and seek sinful pleasures to obtain temporary happiness.

so many don't realize this it's insane.

Well, what's your interpretation? The particles more or less take similar paths, the only difference being that in some cases we can't tell which was path was taken and in some, we can. The physical systems in both cases are basically the same, so what actually changes from the perspective of the photon that makes it act differently?

From the photons perspective the interaction with the physical experiment and the physical means of the observer detecting the photon. In general what I’m saying is that we don’t “know” squat. The theory is either incomplete or wrong.

Even more generally, just because the maths work doesn’t mean it’s right in describing what’s happening in our physical world. If a math equation doesn’t have a corresponding physical explanation that can be pointed at then I am automatically skeptical. ( constants and other non physical values)

Not remotely close to "proof" of course ;)

Photons have no mass. The energy they carry does.

It actually weighs bcz light has momentum

@@anandsuralkar2947 The momentum the light carries doesn't mean it has mass, it means it has energy. Even though mass and energy are somewhat interchangeable, it's not accurate in this case because in order to move at the speed of light you need to have either no mass or infinite energy.

@@armchairgravy5148 energy doesn't have mass. What book are you reading lol There's a few specific reasons a photon in a mirrored box seems to weigh something vs. a photon in an unbound state.
