Quantum Entanglement Proves Universe Isn't Locally Real! #shorts

[00:00:00]In 1964, a physicist named John Bell published a paper with a key insight.

[00:00:05]Bell had figured out how to turn Einstein's philosophical argument into a testable mathematical prediction. He proved that if hidden variables existed, if particles really did carry predetermined instructions, then measurements taken on entangled pairs would only correlate up to a specific statistical threshold. If experiments found correlations above that ceiling, hidden variables were dead. They just couldn't be true and Einstein would be wrong. And the universe would definitively not be locally real. The Bell inequality was violated. The correlations were too strong. No hidden instructions could explain it. He designed an experiment where the measurement settings were switched after the entangled photons had already left their source in billions of a second.

[00:00:52]Way too fast for a signal to pass between them. Too fast for any pre-written instructions to account for the change. The Bell inequality was violated again. In 2017, his team used light emitted by stars hundreds of light-years away to randomly set the measurement parameters of the experiment. If some hidden cosmic conspiracy was faking entanglement, it would have needed to be set in motion before those stars emitted that light.

[00:01:21]Centuries before anyone designed this test, before Einstein was even born.

[00:01:26]Didn't matter. The Bell inequality was still violated. In October of 2022, Aspect, Clauser, and Zeilinger were awarded the Nobel Prize in Physics for this body of work. The official citation was for experiments with entangled photons establishing the violation of Bell inequalities and pioneering quantum information science. Scientific American ran the headline, "The Universe is not locally real" and the physics Nobel Prize winners proved it. Hopefully this far in, you guys see that that's not flowery language. That's the conclusion of the most rigorous experimental physics of the last 50 years.
