Lab Triggers False Vacuum Analogy with Ring of Rydberg Atoms
Physicists at Tsinghua University used a ring of highly excited Rydberg atoms to simulate false vacuum decay, engineering two competing vacuum states that act like false and true vacua. By breaking symmetry with lasers, the ring transitions toward the true vacuum, producing a quantum bubble that mirrors how a lower-energy state could nucleate and, in theory, sweep across the cosmos. The experiment provides a controllable platform to study the quantum–relativistic crossover and test predictions about how such a transition might unfold in principle, without posing any danger to reality.
