General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from ...

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

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 ...

A photon emitted from a star a billion light-years away arrives at a telescope having experienced no time whatsoever. Not ...

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

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, Einstein’s revolutionary theory of gravity, reinterprets gravitational interactions as phenomena emerging from the curvature of spacetime rather than as forces in the traditional ...

In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to ...

A team of physicists has proposed a specific modification to Einstein’s general relativity that could eliminate the Big Bang ...

A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

Albert Einstein's general theories of relativity have been used to create tiny microscopic robots that can essentially "swim" ...
