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 ...

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the ...

In many universes, typically those on TV shows or in movies, time travel is not much more difficult than driving downtown in any major city during rush hour. Sure, the traffic can get gnarly, but no ...

Time feels like the most familiar thing in the world, yet it hides one of physics’ hardest questions: why do we only remember ...

"Nobody knew that before. It improves our knowledge of the theory itself, the theory of how clocks tick and relativity. The passage of time is fundamental to the theory of relativity: how you realize ...

“The chief attraction of the theory lies in its logical completeness,” wrote Albert Einstein after publishing his general theory of relativity in 1915. “If a single one of the conclusions drawn from ...

Everyone knows Albert Einstein was a genius, but can you explain what he’s famous for? Arguably his foremost theory, his general theory of relativity, turns 100 years old this week. It was actually ...

New York — More than a century after Albert Einstein proposed it, his theory of general relativity has passed another test. With giant telescopes pointed at the center of our galaxy, a team of ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

A South Korean physicist has proposed a theoretical framework that could support the unification of quantum mechanics and the ...

In the gloomy days of January, time seems to drag. According to the Einstein theory of relativity, it actually does—in a minute amount that means little to anyone except a scientist. During its annual ...

NIST scientists calculated that clocks on Mars would be an average of 477 millionths of a second faster than clocks telling ...
