There Is Something Faster Than Light

Summary by Krater

This video explores the Einstein-Podolsky-Rosen paradox, Copenhagen interpretation of quantum mechanics, local hidden variables, and Bell's theorem, explaining how quantum mechanics is non-local and cannot be explained by local hidden variable theories.

Answers: Does quantum mechanics really violate locality?

• quantum mechanics
• EPR paradox
• Copenhagen interpretation
• local hidden variables
• Bell's theorem
• entanglement
• nonlocality
• quantum physics

What it concludes

• Quantum mechanics requires instant influences across distance, violating locality.
• The Einstein-Podolsky-Rosen (EPR) paper argued that quantum mechanics is incomplete and proposed local hidden variables.
• Bell's theorem proved that local hidden variable theories make different statistical predictions than quantum mechanics for entanglement experiments.
• Experimental tests of Bell's theorem have consistently confirmed quantum mechanics and ruled out local hidden variable theories.
• Quantum mechanics is non-local, but this non-locality cannot be used to send faster-than-light messages.
