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 ...

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 travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...

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.

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 principle of relativity, as initially described by Galileo, posits that the laws of physics remain consistent regardless of an observer's relative motion. Einstein's special relativity ...

Black holes are strange and fascinating celestial phenomena that challenge the laws of physics. From swallowing up entire stars to warping the very fabric of space-time and generating massive gravity ...

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.
