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

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 ...

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

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 claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

A rare manuscript featuring early calculations that led to Albert Einstein's general theory of relativity sold for just over $13 million at an auction in Paris Tuesday, becoming the most expensive ...

China has quietly solved a problem that only becomes obvious once you try to live and work off-world: clocks on the moon do ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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 ...

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 ...

It was co-written with his lifelong friend, the Swiss engineer Michele Besso. LONDON -- A rare manuscript by Albert Einstein that changed the course of modern science was just sold for over 13.3 ...
