The Terrifying Quantum Entanglement Theory That Breaks Reality

Summary by Krater

This video explains the concept of quantum entanglement, how it challenges classical physics and the assumption of local realism, and what it implies about the fundamental nature of reality and space.

Answers: What is quantum entanglement and why does it challenge our understanding of reality?

• quantum entanglement
• local realism
• Bell's inequality
• spooky action at a distance
• decoherence

What it concludes

• Quantum entanglement reveals that particles do not have definite properties until they are measured.
• Albert Einstein rejected quantum entanglement and proposed the existence of hidden variables to preserve local realism.
• Bell's inequality provided a clear experimental test to determine whether hidden variables exist or local realism must be abandoned.
• Experiments have consistently violated Bell's inequality, proving that local hidden variables do not exist.
• Entanglement implies that reality at its deepest level is made of relationships rather than independent objects.
