Post-spacetime physics refers to the idea that our familiar 4D spacetime is not fundamental but emerges from deeper ...

Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could ...

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this ...

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 ...

Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure communication at scale, and to connect ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Bell's theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles. These ...

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 — ...

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 and the latter a point in space, but in both cases the normally ...

Quantum field dynamics in curved spacetime addresses how quantum fields—fundamental entities underpinning matter and forces—behave in the presence of gravitational curvature. Unlike flat Minkowski ...
