A new physics paper proposes modifications to Einstein’s theory of relativity that could solve one of the biggest issues ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1963, Roy Kerr, a New Zealand-based mathematician proposed a set of equations that explain the properties of rotating black ...

The study of black holes within the framework of general relativity continues to advance our understanding of gravitation under extreme conditions. Black holes, with their intricate interplay of mass, ...

A peer-reviewed paper published in The European Physical Journal C presents a modification to Einstein’s general relativity ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

Three physicists have proposed a modification to Einstein’s general relativity that, if confirmed, could eliminate the ...

A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...

New impressions A visualization of a curved space–time “sea” from the general-relativity simulations carried out by the authors.(Courtesy: James Mertens) From the Genesis story in the Old Testament to ...

What if the technology you use every day depends on a subtle distortion of time itself? The answer lies in a century-old idea ...

General Relativity reinterprets the force of gravity not as a traditional force but as a manifestation of the curvature of spacetime. Its formulation rests on a rigorous mathematical framework built ...
