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 ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the ...

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 ...

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

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

The French philosopher Renee Descartes took some time before convincing himself that he really existed. Or, in his words, “Cogito, ergo sum,” which is Latin for I think, therefore I am. While most of ...

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 ...

A new software package detailed by Chinese scientists promises to tell what time it is on the moon, accounting for effects of ...

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire field ...

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 ...
