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 This framework was superseded by the geometric paradigm ...

Describing natural phenomena with geometric language is one of the most important achievements of modern physics. In the context of general relativity, Einstein treats spacetime as a dynamic geometric ...

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 ...

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 place in the universe where the ordinary rules simply stop working. Time slows to a crawl. Space curves back on ...

Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their physical existence. One theory suggests that these ...

A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole physically twist the fabric of spacetime around it. By tracking the death spiral ...

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 isn’t something that exists; it’s a model for describing how events happen. Treating events as objects creates philosophical confusion and fuels misconceptions, such as time-travel paradoxes ...
