The Moon Is Not the Same Gravity Depth as the Earth

The way GPS works is of course based on a common timing signal and GPS satellites broadcasting kind of their time. So our approach to GPS like position in navigation capabilities does rely on very precise clocks and timing signals really. And so there is actually this special relativity issue of how do we think about approaches to clocks that account for the fact that the moon is not the same depth of gravity well as the earth? How do you coordinate time between earth and places that are not gravitationally on the surface of the earth? I think one of the exciting things about our solar system is we have a lot of places where someday, some day humans might be living and creating communities. We're just going to
