The “minute” on your phone is not a natural thing. Nothing in the sky divides an hour into 60 equal parts. Humans invented ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

And because the speed of light is very, very large compared to everyday speeds, very small mistakes in the measurement of time get reflected into significant changes in distance. So if you make small ...

Physicists long believed time was a basic feature of the universe. But it may just emerge from cosmic information.
