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 ...

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

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

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

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

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

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

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 ...

Now it seems that wormholes, those shortcut tunnels through time and space that Albert Einstein theorized and that science fiction depicts as portals between two distant galactic points, are at the ...

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 ...
