Space and time are one thing. Spacetime. Space is expanding, therefore time is expanding. Objects in space bend space, cause time to go by more quickly and attract other objects. All of which increase with the size of the object. Everything is traveling through time or more specifically time is expanding for everything. On Earth, all of our time moves almost exactly the same and we are attracted to Earth the same. Get away from Earth and these two items both reduce. Is this because gravity is the same thing as being pushed through time by the larger object? Is getting off of the Earth in spacetime on your own, similar to jumping off of a moving train, no longer being pushed along at the same relative speed as the larger object, am I free to have my own speed relative to time, which is much less due to the much lower drag I have to keep me going as fast as time rushes by me? Is gravity the product of two objects having different relative motion in time from each other?
