Einstein's Quantum Riddle FULL SPECIAL | NOVA | PBS America

Quantum entanglement is poised to revolutionize technology from networks to code breaking–but first we need to know it’s real. Join physicists as they capture light from the universe to prove Einstein’s “spooky action at a distance.”

Respect to the cameraman for capturing the universe himself for this documentary!

[dkexpat]

Thank you America for sharing this with the world, love it.

Beautiful! Knowing now that space does not exist (space is nothing but entangled particles), makes life extraordinarily meaningful. The cosmic oneness that is!

Pbs did a couple of great documentaries decades ago and then retelling those stories ever since.

Brilliant ! This brings into focus another variable or measure apart from the usual length (L), mass (M) & time (T) that we usually associate with Space (Space-Time). The fourth measure is Frequency that is used in Communications & can't be ignored as a Physical quantity - for the full understanding of Universe. It is the bread & butter of Communications engineers.

Never seen it before. That was wonderful! I learned so much. Thanks for posting! I have a much better understanding of Quantum Computing now.

" the most incredible aspect of the Universe is that it is credible " Albert Einstein

[FARDEEN.MUSTAFA]

This was a great documentary about Quantum mechanics and Quantum entanglement which is famous as spooky action at a distance by great Albert Einstein.
His General Relativity also interacts with modern Particle Physics to predict theory of Single Graviton Particle which is outstanding.
The Single Graviton Particle is million times powerful than electron and other particles. A beautiful article can be written about theory of Single Graviton Particle to predict Its mass, energy, light and power.

This blew my mind!! 😲 Thank you for not only explaining but showing the entanglement made the hair stand up on the back of my neck!! So much more to learn and I can't wait to learn more myself!! 👏👏

I think Murphy's law should fall into the realm of quantum entanglement. "If it can go wrong It will go wrong and if it shouldn't happen it will happen".

[ericephemetherson]

I am very much confused by physicists using the word ''perhaps''. Also, the issue of cause and effect is rather incoherent because the effect can actually be obvious without any cause. Also, the video exaggerates the fact that Einstein married space with time. We have a definition of space but there exists no definition of time and using time in equations is simply an inadequate approach to express time mathematically. For what is time if there is no no definition of time? A clock cannot be applied to math for it is not something that represents time. Quantum entanglement says that two particles communicate involving no time. And again, how can we know that if no definition of time is applied to this spooky action at a distance?

a problem with saying its a cosmic bell tests, if a superluminal signal can travel faster than light.. then the selection of measurement setting and its randomization could be considered local just as well as if the randomness source was in the same room, it doesn't really matter how far away your source of randomness is, just whether you have a distribution of settings that are roughly uniform over the different settings, but even then it cannot be shown at this level of description whether the particles individually have information about the whole system, or whether there is no explanation of this same fact needed, aka whether this is considered non local or local in an absolute sense.

[charlesbromberick]

Modern physics has moved beyond my reach.

[terrytwotoes]

Are the particals ever together before they are separated and measured because if so then the information is already there and nothing needs to be connecting them

[solomonmeteku]

Is it not possible that the wave from the quasars when observed turns into a particle (quanta) and when again fired /shot to two zorgt location (travels)/ flows as waaien only to turn to observable exact particle when observed/seen at the locations????

22:00 Quantum entanglement 22:27 y la Tecnología surgida de la mecánica cuántica 23:05 46:40 Sí hay entanglement 48:00 Bohr was right ...the spooky entanglement happens

[dco]

I don't quite get the experiment...what are they measuring about the state of the proton? And why is it weird that both are the same at measuring since both exist due to the same Impulse....?

If you drop a marble in a uniform liquid can we not conclude that the wave is the same (sort of) at the opposite side of where we measure the wave?

[AmyWinehouse.]

So in theory if two quantum signals were sent to control a light, one to turn it on one to turn off whould the light stay on or off?

[alexsuited]

So, even though the light is the same from the quasar it won't affect the test. I would argue that from each quasar the light that's emitted is identical. Why, because it's neutral light sterile if u would. Regardless of gases or material when the light comes off the quasar it's identical to any other quasar. I'm just curious if that would affect the test? Or would this be a benefit? The reason I ask is because the spheres or quasar are identical as they are born from the same material. So I guess what I'm saying is those quasar would naturally select the same filters at the same rate because that's all that can happen all things being equal, so should be the result?

[jimkyriacopoulos]

Why are the detectors equidistant? They should move one closer to see if the effect is the same? Are they sure 2 photons are released and really it's only one expanding in all directions
