Planets orbiting two stars were expected to be everywhere. Instead, astronomers have found only a few, and new research ...

Astronomers have long been puzzled by a cosmic mystery: planets orbiting two stars—like Star Wars’ Tatooine—are surprisingly rare, even though they should be common. New research suggests the culprit ...

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 ...

Three physicists have proposed a modification to Einstein’s general relativity that, if confirmed, could eliminate the singularity at the origin of the universe. By adding higher-curvature terms to ...

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 ...

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 ...

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 ...

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 ...

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, ...
