For a century, physicists have sought to reconcile the quantum world with Einstein's curved spacetime, yet the seam between them remains unstitched. A new theoretical framework from researchers at Kyushu University, the University of Waterloo, and Stockholm University now reveals that some experiments believed to glimpse gravity's quantum nature may instead be witnessing something far more familiar: quantum particles traversing an entirely ordinary spacetime. The finding does not close the door on quantum gravity, but it does clarify what genuine evidence would need to look like — a rare and v
