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

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

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 ...

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, ...

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 ...

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.
