science ⚛️ Gravity theory challenged in quantum cat experiment
A new experiment has eliminated one major explanation for quantum decoherence involving gravity. Researchers at INFN Gran Sasso National Laboratory conducted the test to check gravity's role in quantum states. Data gathered over 62 days showed no predicted radiation signal from spacetime fluctuations. This finding rules out an important version of the Károlyházy model concerning quantum mechanics. The result narrows the search for theories connecting gravity and quantum mechanics.
