Newton’s law of universal gravitation conceived gravity as a force acting at a distance within an absolute Euclidean space and universal time. This framework was superseded by the geometric paradigm ...

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 ...

Classical electrodynamics describes the interplay of electric and magnetic fields with charges and currents through Maxwell’s equations. In their covariant form these equations are naturally expressed ...

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

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Physicists from the Eötvös Loránd University (ELTE) have been conducting research on the matter constituting the atomic nucleus, utilizing the world’s three most powerful particle accelerators. Their ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Spacetime is often described as the stage on which the universe unfolds, a four-dimensional blend of space and time that bends, stretches and shifts as matter and energy move through it. However, ...

Could the route to the stars be paved not by impossible physics, but by spacetime itself? A new warp drive model has been ...

A ring in space, at least on paper, can do something a black hole cannot. It can connect distant regions without forcing ...
