From what we know about No Man’s Sky, aging won’t be a source of in-game anxiety. Although characters can definitely die and the universe is big enough to explore into one’s dotage, the archbishop won ...

IntroductionIn this series, we are testing the idea that "the universe might be a simulation running on a giant computer" by ...

JILA physicists have measured Albert Einstein's theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that two tiny atomic clocks, ...

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 ...

What is time, and why does it seem to flow in only one direction? This video explores modern physics’ take on time—from the ...

Albert Einstein’s theory of general relativity is packed with weird insights about our reality, but perhaps the most mind-boggling is the fact that strong gravitational fields or incredibly high ...

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.
