“The passage of time is fundamental to the theory of relativity: how you realize it, how you calculate it, and what influences it,” said Bijunath Patla, a physicist at the National Institute of ...

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.

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the difference, showing that Mars clocks tick slightly faster—and fluctuate over the ...

Time has an arrow: It only ever seems to move in one direction. The future is always unknown to us, while the past forever remains locked and inaccessible. And yet, the vast majority of the laws of ...

The Sagnac effect, first observed over a century ago, remains central to our understanding of relativistic kinematics and the operational definitions of simultaneity. Fundamentally, this effect arises ...

Here’s what you’ll learn in this story: Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with.
