    Because there’s less gravity on the moon, time there moves a tad more quickly – 58.7 microseconds every day – compared to on Earth.

    Okay, that’s even cooler than I thought.

      so atomic clocks on the moon would go out of sync over a long period compared to those on earth…

        When you are measuring precise distance to the Moon using lasers, 50 microseconds is about 1.5 kilometers.

          Except the light is also affected by time dilation so surely it wouldn’t matter.

          It would only matter if you were measuring a distance between a satellite and the surface.
