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

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

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 ...

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 ...

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

1915 and the theory of General Relativity: In 1911, Einstein starting talking about the idea that space is curved. In 1915 Albert Einstein put fourth a theory that mass, or a large object, like the ...

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 ...

Very few people outside of Germany had ever heard of Albert Einstein in the early part of 1919. Even his mother was once unsure of his greatness. Asked if her son would amount to anything, she once ...

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 ...

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 ...

Like Max Planck, Albert Einstein first studied mathematics because he was told that everything interesting in physics had already been discovered. But in 1905, Einstein, a young cleark at the Swiss ...

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 ...
