The ability to detect gravitational waves is rapidly propelling us into a new era of both astronomy and physics. New instruments like the Laser Interferometer Gravitational-Wave Observatory (LIGO) ...

Albert Einstein can rest a little easier: The first effort to measure how quickly gravity exerts its influence indicates that it more or less matches the speed of light, scientists reported Tuesday.

COLUMBIA, Mo. – Scientists have attempted to disprove Albert Einstein’s theory of general relativity for the better part of a century. After testing and confirming Einstein’s prediction in 2002 that ...

More precise measurements would be needed to lower the margin of error, but the astronomers claim "You can rule out a speed of gravity greater than twice the speed of light with a high degree of ...

SEATTLE -- Einstein was right. The speed of gravity matches the speed of light, according to astronomers who took advantage of a rare planetary alignment to measure one of the fundamental forces of ...

Proof of gravitational waves came on Sept. 14, 2015, when two giant, L-shaped, 2-mile-long laser instruments, one set up in a swamp in Louisiana and the other in Hanford, Washington, detected a tiny ...

Albert Einstein may have been right that gravity travels at the same speed as light but, contrary to a claim made earlier this year, the theory has not yet been proven. A scientist at Lawrence ...

In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley ...

Two stellar mass black holes, if they merge in the vicinity of a supermassive black hole, could have their gravitational wave signal affected by the strongly curved space around them. If Einstein's ...

A small but incredibly fast unwanted guest is about to swing past Earth at the speed of light. Yeah, this is the tiniest ...

Scientists have attempted to disprove Albert Einstein's theory of general relativity for the better part of a century. After testing and confirming Einstein's prediction in 2002 that gravity moves at ...

The speed of the wave propagating along the string is the speed of gravity.<HR></BLOCKQUOTE><BR>I think your string analogy would work better if you make the string very long and instead of "yanking" ...
