An international team of scientists has succeeded in proving, for the first time at the quantum scale, the "equivalence principle," one of the cornerstones of Albert Einstein's General Theory of Relativity.
Wild Experiment Reveals Quantum Objects Do Obey Gravity
Quantum mechanics and Einstein's general relativity explain how the Universe works at the tiniest and largest scales, respectively. Quantum mechanics has revealed the probabilistic nature of fundamental particles, while Einstein's general relativity describes how the fabric of spacetime is warped by mass and energy to produce gravity.
When Einstein Met Quantum Mechanics: Landmark Experiments Shed Light on the Gravity of the Microcosm
An international team of scientists has performed a landmark experiment that for the first time directly examined how gravity affects a quantum object in free fall. The experiment used extremely cold rubidium atoms, which were placed in a quantum superposition so that each atom behaved as if it were following two different paths at once.
