Unifying physics just got harder: Study challenges fundamental test of quantum gravity
SMRTR summary
Scientists at Royal Holloway University challenge a key test for quantum gravity by showing that classical gravity could create quantum entanglement between objects, not just quantum gravity as previously thought. This discovery complicates efforts to prove gravity operates quantum mechanically through tabletop experiments, potentially making the unification of physics more difficult.
