What is Bell's Theorem?

Bell's Theorem is a fundamental result in quantum mechanics that shows that certain predictions of quantum mechanics are incompatible with local hidden variable theories.

Can you explain what local hidden variable theories are?

Local hidden variable theories are models that attempt to explain quantum phenomena by assuming that particles have predetermined properties, independent of measurement.

What are the implications of Bell's Theorem?

The implications of Bell's Theorem challenge our understanding of reality, suggesting that particles can be entangled and that information can be transmitted instantaneously.

How does this relate to quantum entanglement?

Bell's Theorem directly relates to quantum entanglement by demonstrating that entangled particles exhibit correlations that cannot be explained by local hidden variables.
