In general relativity, gravity changes time. Gravitational potential = - G M / R. Time change r = At/t = A/c². A satellite (e.g., GPS) orbits 21 km above Earth surface, and gravity at the satellites are a little different from Earth surface. The distance error is Ad = c At. Ad is km in one day Please do not copy and paste. Thank you!
