AI Summary

Physicists tested a long‑standing hypothesis that minute spacetime fluctuations from gravity could collapse quantum superpositions. The experiment was conducted deep underground at Italy’s Gran Sasso laboratory using a highly shielded germanium detector. Over 62 days of data collection, researchers looked for an extremely faint radiation signal predicted by the theory. No such signal was observed, challenging the idea that gravity‑induced fluctuations are responsible for the loss of quantum behavior in everyday conditions.
