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 ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.

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 ...

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast cosmos. Quantum mechanics rules subatomic particles, while general relativity ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible. Tachyons are a ...

"God does not play dice." This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics. Paradoxically, his theory of relativity has become an essential tool for ...
