Quantum Mechanics Reveals a Faster-Than-Light Effect
SMRTR summary
A new Veritasium video explores how quantum mechanics allows particles to instantly influence each other across vast distances, seemingly violating Einstein's rule that nothing travels faster than light. When two entangled particles are separated by thousands of light years, measuring one particle's spin immediately determines the other's spin, creating what Einstein called "spooky action at a distance." Bell's theorem and experiments in the 1970s-80s proved this quantum effect is real, though it cannot transmit information or violate relativity.
