Testing Feynman's Infinite Quantum Paths

Richard Feynman famously proposed that quantum particles travel between two points by taking every possible path simultaneously, an idea that remained untested as a physical reality for decades. Researchers have now directly confirmed Feynman's postulates by measuring a single photon's probability amplitudes across more than 1.4 million distinct paths. The experiment proves that quantum probabilities emerge from the interference of all possible routes, with each path contributing an equal magnitude to the final physical outcome.
