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 ...

Here’s what you’ll learn when you read this story: Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation ...

About a century ago, scientists were struggling to reconcile what seemed like a contradiction in Albert Einstein's theory of general relativity. Published in 1915, and already widely accepted ...
