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 ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

The tiny bots follow patterns of light and "artificial space-time," navigating like craft following the curved space around a ...

One of the most mind-bending aspects of Albert Einstein's Theory of Relativity is time dilation. Time moves more slowly for a person in motion compared to a person at rest. This effect also applies in ...

In Einstein's famous theory of relativity the concepts of immutable space and time aren't just put aside, they're explicitly and emphatically rejected. Space and time are now woven into a coexisting ...

A millimeter might not seem like much. But even a distance that small can alter the flow of time. “This is fantastic,” says theoretical physicist Marianna Safronova of the University of Delaware in ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

Thanks to Albert Einstein, the US Government wants to establish an official time zone for the Moon. It has less to do with jet lag and more to do with how gravity affects time and can throw a lot of ...
