Einstein was right: Quantum object falling does feel gravity, finds new research

SMRTR summary

Scientists confirmed for the first time that falling quantum objects experience gravity exactly as Einstein predicted. Using ultracold rubidium atoms and a Quantum Galileo Interferometer, researchers split atomic waves into two paths and measured a quantum phase difference matching Einstein's equivalence principle, opening doors for future experiments on larger quantum objects.
