The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the seconds between 'then' and 'now'. Down at the quantum scale of buzzing ...

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

Measuring time might not seem like that complex of a thing. After all, we rely on simply counting seconds between the "then" and the "now." But when you really start to break time down to the quantum ...
