A 100-year-old theory might explain what’s wrong with quantum mechanics

AI Briefing

• – De Broglie's pilot wave theory, proposed in 1924, suggests that particles like electrons have a definite position, rather than existing in multiple places at once. This theory was initially rejected in favor of wave-particle duality, but some physicists are now re-examining its potential to resolve long-standing problems in quantum mechanics. The theory proposes that particles have a 'pilot wave' that guides their motion, rather than existing in a superposition of states.
