Einstein's Gravity Just Passed Its First Real Quantum Physics Exam

A new interferometer split 20,000 rubidium atoms into two paths and found the predicted phase shift, researchers said.

Summary by studyfinds.com
A new experiment measured how gravity affects a falling atom in superposition, confirming a 100-year-old physics prediction.
