The Quantum Experiment That Breaks Time
Season 11
Episode 31
Modern physics is weird. Quantum mechanics gives us Schrödinger's cat, simultaneously alive and dead. Relativity gives us the twin paradox, where a spacefaring twin ages more slowly. But what if we combined them and sent a quantum twin across the galaxy? Could we be both old and young at once? What would that reveal about the quantum nature of time... and birthday candles?
