Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Lorentzian geometry forms the mathematical cornerstone of modern spacetime theory by providing a framework in which the causal structure and metric properties of the universe can be rigorously ...

A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

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 ...

A recent study published in Nuclear Physics B examines how hidden dimensions might influence the physical reality that we ...

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 ...

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 ...
