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 ...

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

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges. Now, ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

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 ...

While you already may be aware of Albert Einstein and his Theory of Relativity, it’s worth a refresher before we discuss the theory of financial relativity. There’s a famous example of his theory ...

Help me arsians.<BR><BR>We've been having a discussion here at work about Special Relativity, specifically regarding time dilation. I understand, albeit in layman's terms, about how it functions and ...
