Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Time runs faster on Mars (477 microseconds/day) due to relativity. Discover how this fundamental physics challenge requires dynamic correction to prevent massive GPS errors and secure future deep ...

Did you know that moving a clock one inch toward the ground would result in a slower tick compared to the same clock positioned higher up? Gravity doesn't just pull things; it also bends time.

Santa Claus is not breaking the law. He is just using Einstein's physics to bend the rules of time and deliver presents to ...

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.

Tiny “Ferris wheels” made from light and extremely cold particles could allow researchers to test a facet of Albert Einstein’s theory of relativity on unprecedentedly small scales. Theories of special ...
