For centuries, humans have thought of time as a linear concept - but time dilation challenges that perception. Just as gravity pulls things down, time simply moves forward at a constant, unwavering ...

Time is a fickle thing. Depending on your frame of reference, it can appear to pass slower or quicker, thanks to a wonky phenomenon known as time dilation that was described in Albert Einstein's ...

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 ...

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 ...

Time moves faster on Mars than on Earth. Physicists have confirmed this effect, crucial for future space missions. Even tiny differences in time matter for spacecraft navigation and communication.

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 ...

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.
