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 ...

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

Consider two identical accurate clocks, one stationary and the other moving at close to light speed. Due to the effects of special relativity the moving clock measures a shorter time than the ...

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

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.

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.

Einstein correctly predicted that time slows when you're flying fast, but to experience "time dilation" most spectacularly, you'd have to travel into a black hole, says astrophysicist Chris Lintott.
