Understand Einstein’s General Relativity with a clear and easy-to-follow explanation that breaks down complex ideas like ...

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 ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

Einstein’s equations were written for chalkboards and paper, yet they now sit at the heart of some of the most visually ...

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 ...

The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...

Einstein's theory of general relativity is our best description of the universe at large scales, but a new observation that reports a "glitch" in gravity around ancient structures could force it to be ...

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 ...

After Albert Einstein published his special theory of relativity in 1905, he spent the next decade trying to come up with a theory of gravity. But for years, he kept running up against a problem. He ...

A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...
