In 1915, Einstein published his paper on general relativity, a theory of gravitation. While Newton’s gravity explained everyday phenomena, it did not explain the nature of gravity itself.

Researchers say they may have achieved Einstein's vision of a "unified field theory" that can unite two of nature's ...

A new recipe for gravity could help solve some of the universe's greatest mysteries. It suggests that the concept of "quantum ...

this theory introduced brand-new ideas to science. It opened up an entire field of physics, but left Einstein with some nagging questions. The problems of gravity and acceleration would not go away.

Einstein’s general theory of relativity can be summed ... general relativity is one of two pillars of modern physics – our working theory of gravity and of the very large, of planets, galaxies ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String ...

A new theory links gravity to quantum entropy and introduces the G-field, possibly explaining dark matter and cosmic ...

Using the mathematics of Einstein's 1915 theory of gravity, called general relativity, scientists can model the interior of a black hole. The problem is that, when they do this, general relativity ...

You may have seen the recent news of dark energy observations that alter our understanding of the cosmos, but where has the ...

Images of Einstein have become even more common ... “He was single-minded in reconciling general relativity with Newton’s theory of gravity, and he hit a home run. But he was also single ...

This effect, predicted by Einstein’s theory of general relativity ... This approach could reshape our understanding of gravity, black holes, and eve ...

Physicists have taken a bold step beyond Einstein's special theory of relativity, proposing an expansion of special ...
