Theoretical physicists have spent decades wrestling with a disorienting possibility: that the flow of time is not woven into the basic laws of physics but instead emerges from gravity’s effect on heat ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth curvature of spacetime, the other the jittery statistics of particles and ...

Researchers at the Indian Institute of Bombay have developed a new diagnostic tool, dynamical fidelity susceptibility (DFS), to test the quantum nature of gravity.
