Kyushu University finds quantum gravity tests may mirror normal gravity

Researchers from Kyushu University, the University of Waterloo, and Stockholm University are challenging how physicists search for quantum gravity, the long-sought theory uniting quantum mechanics and Einstein’s gravity. The team developed a new framework called “Relativity of Spacetime Superpositions” that reveals some proposed quantum gravity experiments may simply reflect quantum particles within ordinary gravity. “What we found is that some of these scenarios can be viewed from two equally valid perspectives,” explains Associate…
