Hello, I have had this lingering curiosity for a while. I read through https://www.physicsforums.com/showthread.php?t=5732" thread a second ago and would like to kind of take it a step further on a tangent. I have only read about gravity effects and space-time as such they are "fabric-like", and seen many picture as http://images.google.com/imgres?img...rg.mozilla:en-US:official&sa=N&start=42&um=1". Which to me is very easy to understand, but I have never seen this model with a secondary satellite. Imagine our sun in the center and the Earth being the satellite in orbit, then the "ripple" in space-time that the Earth generates would be "inclined" or "tilted" as to that of the Suns "ripple". Now I am curious how this model encompasses the Moon. When the moon rounds the Earth towards the Sun the inertia and "downhill" momentum from the "tilted ripple" is not going to be the same as when the moon rounds the Earth away from the Sun ("uphill"). This would cause the Moon to rather trail into the Sun or Crash into the Earth. I know the above is not correct, and that space-time is not actually an entity. Can someone set me straight on how the spacetime model woul encompass the moon orbiting?
