Einstein’s Gravity Just Passed a Strange New Quantum Test

An experiment comparing falling and stationary rubidium atomic waves found a quantum phase difference consistent with Einstein’s equivalence principle. A rubidium atom can behave as a wave that researchers can split between two paths. This allows the same atom to effectively follow both paths at once, without being broken into pieces. Physicists have now used [...]
