Because the moon has less gravity than Earth does, time passes slightly differently there. This effect was first predicted by ...

The researchers used measurements from the Moon's gravity to program a software package that can measure lunar time.

The way in which time progresses on the Moon is becoming increasingly relevant as both countries push toward their next lunar ...

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.

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...
