A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the ...

Since 1915 when Albert Einstein published his theory of general relativity, scientists have worked on testing its limits, and with the results of this 16-year test, it still holds up. Professor ...

Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.

(Inside Science) — Just six years ago, scientists with the Laser Interferometer Gravitational-Wave Observatory, or LIGO, in Louisiana and Washington measured a unique undulating signal when the ...

In another verification of the validity of Einstein's theory of general relativity scientists have used two finely tuned optical lattice clocks to make new ultra-precise measurements of the time ...
