The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light moves through space at a constant speed has supported some of physics’ most ...

University of Adelaide applied mathematicians have extended Einstein’s theory of special relativity to work beyond the speed of light. Einstein’s theory holds that nothing could move faster than the ...

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 ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...

GENEVA - One of the pillars of physics and Einstein's theory of relativity - that nothing can go faster than light - was rocked Thursday by new findings from one of the world's foremost laboratories.

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

Uncrowned is a new destination for all things MMA, boxing, wrestling, and more, featuring Ariel Helwani. Yahoo Racing is powered by Motorsport Network, providing expert reporting, analysis, and ...

"A three-body problem is extremely complicated. Now we're dealing with four: the sun, Earth, the moon and Mars. The heavy ...
