A tiny glass sphere hovers in a laser beam. If its oscillations die out faster than calculations predict, quantum mechanics is coming apart at the seams. Physicists are setting up this experiment to capture the moment when the world stops being probabilistic and becomes definite.
🎯 A light beam holds a particle in a vacuum like invisible tweezers. This technology is used to manipulate living cells — scientists literally sort them as if playing billiards with bacteria.
