what does it mean to say 'everything is relative'?? learn about the super wild concepts in special and general relativity using everyday, real world examples! It will blow your mind how weird and wonderful our universe is 💖
CORRECTION: due to gravitational time dilation, earth clocks run SLOWER than satellite clocks . this is because time dilation due to gravity slows time MORE than the time dilation due to speed of the satellites.
more info: At 3.874 kilometers per second, the clocks in the GPS satellites are traveling at great speed, and that makes the clocks on the satellites appear to run slower than the clocks on earth by about 7 microseconds a day. However, this apparent slowing of the clocks in orbit is counteracted by the weaker gravity around them. The weakness of gravity makes the clocks in the satellites appear to run faster than the clocks on earth by about 45 microseconds a day. Therefore, on balance, the clocks in the GPS satellites in space appear to run faster by about 38 microseconds a day than the clocks in GPS receivers on earth.
