@physicsgene on Instagram: "QUANTUM PHYSICS JUST FOUND A NEW WAY TO MEASURE TIME—WITHOUT A CLOCK ⏰⚛️ Scientists discovered how to measure time using quantum interference in atoms—no ticking, no gears, no oscillations. Time measured by the changing shape of atoms themselves. The Concept: A clock that doesn’t tick. Time is measured by observing how quantum states evolve in Rydberg states—atoms with electrons in extreme orbits. How It Works: 1. Laser excites atoms into Rydberg wave-packets 2. Wave-
