Regarding “light clocks” and how moving clocks run slow: Does this mean that, if you were on the ISS or some other satellite, clocks on Earth run slow?

Question

I’m still very confused by how clocks could end up out of sync in this way. For example, if you were to send a clock into space, it “runs slow” for awhile, then bring it back to Earth, would it then be permanently “behind” unless it’s manually caught up?

Answer 1

yeah moving clocks tick at different rates, GPS had this exact problem, allegedly some scientists didn’t believe it, so they launched the clocks synced to the earth, and GPS immediately started drifting until they applied the correction for relativistic effects
