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 ...

Travelling into a black hole would do strange things to time (Credit: Edouard Taufenbach/Bastien Pourtout) Einstein correctly predicted that time slows when you're flying fast, but to experience "time ...

Cool research story with connections to atomic clocks, Einstein and quantum mechanics. The research shows the 'spooky' interference that can impact even the most sophisticated clocks. A phenomenon of ...

The world’s most precise atomic clock has confirmed that the time dilation predicted by Albert Einstein’s theory of general relativity works on the scale of millimetres. Physicists have been unable to ...

Despite more than a century of efforts to show otherwise, it seems Albert Einstein can still do no wrong. Or at least that’s the case for his special theory of relativity, which predicts that time ...

Tracking time is one of those things that seems easy, until you really start to get into the details of what time actually is. We define a second as 9,192,631,770 oscillations of a cesium atom.

Physicists from JILA — a CU Boulder and National Institute of Standards and Technology institute — were able to measure an effect called time dilation at the smallest scale ever, which they say could ...
