Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy. Scientists could soon test Einstein's theory of ...

In 1916, Einstein announced his holy grail theory of general relativity. Basically, Einstein realized that space is much more than the "space" we live in and that time transcends the clocks we've ...

It is difficult to picture the curved geometry of general relativity, but if one thinks of space-time as a kind of fabric, then a massive object stretches the surrounding fabric such that anything ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

Jut think about it, on the flat spacetime diagrams of ... fleshed out all of general relativity yet, but there's one experimental fact that I can use to show you that space time must be curved ...

His eventual breakthrough was to realize that space-time could be dynamic and curved, and that the effects of that curvature are what you and I experience as “gravity.” The fruits of this inspiration ...

For the first time, a mathematical framework proves that Einstein’s theory of general relativity, which explains the ...

In the curved space­time of general relativity, a cat or an astronaut can pull off more impressive stunts. Our hero covered the distance back to his spacecraft in somewhat more than an hour—no ...

2015 will mark another important Einstein anniversary: the centenary of the presentation of his general theory of relativity. Among physicists ... Newton’s force of gravity with a warping of ...

In general relativity, the distortions of time and space are predicted to be the same; in other theories of gravity, this is not always the case. That means that by measuring the distortion of ...
