Why can't we use the 3 particle entanglement described in the experiment to communicate instantly over a distance? Suppose Alice has the atom and Bob has the electron and positron. If Alice measures her atom, the spin states of Bob's particles become defined. Then he can do an interference test and discover that there is no interference, and know that Alice made her measurement. I know that this isn't supposed to work, but I can't figure out why.

Interesting, video, thank you for making it. There is no tide in the bathtub because it is all under the same force. Water isn’t really compressible, so less gravity isn’t going to make it expand. The water at the edge of the bathtub will experience the same force as the water in the center of the bathtub, so no tidal bulge.

If I moved forward would my cosmic event horizon actually change? 🤔 As I move forward, time for me slows down to compensate, so my overall spacetime stays the same - thus my cosmic event horizon stays the same right???

Funfact about predetermination: It's real. Another fun fact: It will have zero effect on perception of free will. Humans do not have the unmodified capabilities to know what will happen more then a few second in the future, and even then their accuracy is terrible. This is the absolute universally strongest example of 'ignorance is bliss'. We have free will due to our inability to know what will happen next or to connect all the dots that are inexorably converging into inevitability. Even your denial/acceptance of it all is part of it; you were built this way from before your birth and molded by each second of your environment, even if that knowledge leads you itself to another environment. Let that sink in, and then slowly realize it doesn't matter. Perception of free will is as good as the real thing because we would not know either way.

Before I watch Ill answer what I believe. Yes. Yes they exist in the same way the end of a long rope exists even when you cannot see the end of the rope, or even a few feet from where you are on that rope. You're only allowed to travel a certain speed along the rope and it gradually comes into view. This is only true if predetermination exists. I personally believe it does, and human science is slowly coming to this as a fact as we sort through reasons why it doesn't exist (not being able to see or understand something, does not prove that it doesn't exist, it only proves that it not knowable to us in either those approaches, or possibly any approach under the laws of physics. Indeed, existence should be impossible, yet here we are, so there was a catalyst and infinity has a beginning) Everything in existence has a infinitely precise story behind it that reaches back to the beginning of all creation.

What if we could graphically represent human intelligence as a kind of highly detailed "Mind Mandela?" Each area of the mandala would represent some subtle thought behavior that the "average" human mind gravitates to under certain sensory stimulus. Now let's speculate that we encounter an alien species, and we are able to represent their intelligence as a "Mind Mandela." Now let's further speculate that we lay both Mandelas side by side...the human Mandela...and the alien Mandela. It very probably would be that, much to our surprise, the Mandelas look dramatically different. It also may be that the alien Mandela is much more complex than ours. I think this is the situation that we find ourselves in currently. We believe we are alone because the only thing that convinces us otherwise, is if we find intelligence that looks exactly like ours...and that will probably be very unlikely. We may be surrounded by different types of intelligence even more complex than our own... But we feel alone, because we can't recognize it or relate to it.

I'm realy gonna mess with everyone's head. Ok so let's say on the 6th of October,! (my conscious present), we have a conversation and I asked you is this day the present, You laugh and say 'yes of course it is'. Now, let's say, your conscious present is on the 20th of December. You would have a memory of a crazy person 😜 me, asking you is the 6th October the present. my conscious present would be your past, but, when the 6th of October was your conscious present it would be my future. I haven't lived yet, my conscious present would be two and a half month previous to this event. Everyone in the world could be living in a different conscious time, within there own lifetime. Imagine all of time has already played out, everything the whole universe is born and ends in a flash the only thing that gives the univers meaning is what we perceive as the present, Look at it a different way. A 100 year old man in a care home seems to have lived he's entire life but maybe he's conscious present is 50 years before now or maybe he was only just born 🤔 So the past present and future could all exist, and consciousness is spread throughout, space time. Or i could be an alien messing with head

There's an idea. I vote we stick a frozen apple pie on every long distance space probe from here on. "Greetings from Earth, we're glad you / we made it this far. Here's an Earth delicacy in the hopes we can someday be friends. Its molecular construction is included in the case you lot are deathly allergic to it. Don't eat the burnt bits, as it was also used as heat shielding for this probe. Also the metal thing with the fins gives off significant radiation, so don't open that and maybe clean it up if it's all over someone's house. Give us a call, terawatt microwave beam should do. Tootles." - Earthlings.

@8:06 I heard this so often, black holes evaporate and then there is nothing left. what, happens to the particles and the radiation they evaporate if there is no mass beside those black holes left? They have to feed themselves again, also "stuff" can't get removed from the universe (at least that what I learned in school physics) it can change, but never removed? Also, they say the inflation of the universe is due to "dark energy" if those dark particles decay too, why should the universe continue with the inflation? Wouldn't it start collapsing?

Trashman 5 саат мурун
While this is all interesting, I think that while your 'getting off' on seeing the planet from different directions and points of view and stating: "Time is different!" In fact, everyone seeing the planet is seeing the photons NOW, regardless of where their NOW is... For all observers, the planet has moved on, isn't where they are seeing it - they are seeing the photons reflected by the planet, not the planet itself. It's the same as the black hole problem I have: If black holes are infinitely dense and time stops at them - how can we still see them? Wouldn't they simply 'wink' out of existence? Stuck somewhere in the past if time has stopped for them? I just feel there's something else going on - we just haven't noticed it yet, haven't quantified it. Just as because a photon travels at the speed of light it is infinitely dense - which means it can't go anywhere or forms a black hole... but somehow manages to travel to the end of the universe instantly because time doesn't exist for it, yet it takes 8 minutes for light to get from the sun to us... I understand how 'not getting it' means I do get quantum physics? But I just feel, like many others, that there's just other 'stuff' to the universe we just haven't got a clue how to discover, never mind discover - and with us only knowing what 6ish percent of the universe actually is? I feel quietly confident in my belief. After all, if we discover another 6ish percent of the universe? It could be just as complex as the known 6ish percent - and we've still got 88ish percent to go...

Hi Professor Matt, I have a childish question. QED describes particles as an excitation of the respective field. But what is a field? We say the field is the property of space - like say the presence of a magnet modifies its surrounding space in a way that pushes or pulls other magnets. But in this description, a field just becomes a mathematical quark - A few scribbles on some piece of paper. Definitely real particles can't be the vibration of a few scribbles made of ink. Then what is a field? If it's actually a real entity then what kind of entity is that?

I laughed out loud at the end. I already had the notion that maybe the observation of space-time gave us a single slice. And when i say observable I give that job to the universe and everything in it. So when Matt mentioned the quantum physics gives us a possible multiversal future then that gives us our singular past. I know this is wrong, but I love discovering the next steps as educators like Matt, Neil, Brian, and many more give us amatuer scientist more digestible info.

Do the Past and Future Exist? Only now with the sun and moon counting "time" for us. But in eternity - everything just "is".... as God just "is".

Accept Jesus as the death sacrafice for your evil deeds in this lifetime, to spend Eternity in His presense - ON THIS EARTH after He re-creates 😁
