That is still my belief. I am not saying the rock isn't orbiting the big rock, just that Gravity alone does not adequately explain it.
What other force or mechanism could there possibly be to even assist in the smaller being held in orbit around the larger, static electricity, magnetism...?
No one knows mostly because no one looks for anything else, but Gravity is a very weak force when you consider the inverse square rule. There are more than a few Freepers that seem to lean toward an "Electronic Universe." I have no dog in either fight and really don't much care but a lot of consensus science defies common sense. The moon sucks the Oceans up toward it but ignores clouds full of water, ok then.
