Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

Physicists have long believed that detecting the particle of gravity—the graviton—was fundamentally impossible, with the ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear ...
