Gosh, it's fun, though. Plus, we still can't explain gravity. (In the basic sense that gravity is not the primary influence on the formation of the universe, and we don't yet know what has been.)

Ok. But the fact, that there are things with no theory to explain it only solidifies, that science is to be trusted, when there is no counterproof. Since it shows, that not vague theory came up to fill that gap, when it can not be proofen.
