The argument can be (and is being) made that gravity does not pull. It pushes. Problem is, to push it depends on some sort of as-yet undetected “ether”. But it solves some of the paradoxes, like light slowing down in water and then speeding back up when it exits it.
They why are gravity wells like dimples in the fabric of space time? Or maybe they aren't?
I don't know.
It seems electromagnet force does, but not gravity, for its effect is not affected by the accumulation of itself... :)
