Question

do the laws of gravity differ greatly between single solar systems

Answer 1

after the big bang the universe was created by itself, with it the laws of physics, so if physically don't exists, is not from this universe.

Answer 2

Sorry, Tanya, but your answer doesn't make very much sense to me. But I think that since we're talking about solar systems, we are talking about systems similar to our own. I say this because solar means that we have a sun and then you pretty much know the rest. But anyways, the laws of gravity don't differ, but there may perhaps be a circumstantial difference in that the size of the Star will effect the strength of it's gravity. And so is pretty much the only reason I could think of that there would be a significant difference.

Answer 3

The laws of physics is same all over the universe
