An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement ...

Add Yahoo as a preferred source to see more of our stories on Google. The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity. Now a new theoretical study pushes that weirdness into even stranger territory. It ...
