Most of us don’t hear a whale call and think, ‘Wow, look at the special theory of relativity in action.’” Tachyons are a hypothetical particle generally thought to be incongruous with Einstein's ...

In 1905, a 26-year-old patent clerk named Albert Einstein looked at the universe and discovered that time was not what we thought it was. It was not linear. For centuries, everyone assumed the same ...

EVER since Arthur Eddington travelled to the island of Príncipe off Africa to measure starlight bending around the sun during a 1919 eclipse, evidence for Einstein’s theory of general relativity has ...

Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at ...

OUR most accurate clocks are probing a key tenet of Einstein’s theory of relativity: the idea that time isn’t absolute. Any violation of this principle could point us to a long-sought theory that ...

Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet ...

How would our world be viewed by observers moving faster than light in a vacuum? Such a picture would be clearly different from what we encounter every day. "We should expect to see not only phenomena ...

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 ...

Yes, Einstein wrote something along the lines of “time is an illusion.” But it’s not altogether clear what Einstein meant — and to understand what he might have been saying, we must dig into the ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. It's difficult to appreciate how revolutionary of a transformation it ...
