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 ...

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

In 1916, only a year after Albert Einstein had published his general theory of relativity, Karl Schwarzschild used ...

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 ...

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 ...

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 ...
