For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum ...

The first image of a black hole, captured in 2019, has revealed more support for Albert Einstein's theory of general relativity. The new finding has suggested his theory is now 500 times harder to ...

A preliminary analysis of data from the Gravity Probe B satellite has confirmed that the Earth's mass distorts the fabric of space and time as predicted by Einstein's theory of general relativity.

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...

Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet's intricate timekeeping system, ...

Aristos is a Newsweek science and health reporter with the London, U.K., bureau. He is particularly focused on archaeology and paleontology, although he has covered a wide variety of topics ranging ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

In 1915, Albert Einstein put forth a new theory of gravity: General Relativity. Instead of every mass in the Universe instantly reaching across to every other mass and exerting an attractive force, ...

In 1907, Albert Einstein had his “happiest thought” — people in free fall do not feel their own weight. This simple idea laid the foundation for his general theory of relativity, which Einstein ...
