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.

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) ...

PHILADELPHIA, April 7 (UPI) -- Although scientists generally agree the attractive phenomenon of gravity actually travels, its rate of speed remains undetermined, a physicist said Monday. Clifford Will ...

SEATTLE: In a test critical to theories of cosmology, scientists have for the first time measured the speed at which the force of gravity moves. SEATTLE: In a test critical to theories of cosmology, ...

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 ...

Astronomers are taking advantage of a planetary alignment to measure the speed of gravity, one of the assumptions of Albert Einstein's general theory of relativity. Einstein predicted the speed of ...

A ground-breaking experiment is being carried out to measure the speed of gravity. Thanks to a useful planetary alignment, physicists hope to test the general theory of relativity. If we find that the ...

Scientists who announced a landmark first measurement of the speed of gravity on 7 January are fighting back against criticism that their experiment mistakenly measured only the speed of light.

The speed of gravity is the same as that of light, say two physicists. Knowing the speed of gravity is important for theories that attempt to unify the two pillars of physics: general relativity and ...
