relativity established by theoretical physicist Albert Einstein is an important theory that is the basis of modern physics, but there is also an image that it is related to complicated phenomena such ...

Einstein's theory of general relativity has passed its toughest test with flying colors, a new study reports. General relativity, which Einstein proposed in 1916, holds that gravity is a consequence ...

DOES it really matter? Albert Einstein’s theory is an argument upon which the very nature of space and time — and the fate of the universe — depends. At its core, the idea is simple: Space and time — ...

A new study validates Einstein's theory of general relativity in a distant galaxy for the first time. This study supports our current understanding of gravity and provides more evidence for the ...

Einstein’s theory of relativity has explained the universe for more than a century. But under certain conditions, cracks ...

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 ...
