Dark Matter

There are news reports out that cosmologists may finally be able to "see" dark matter by using gamma rays. The existence of dark matter has been postulated for years even though it cannot be seen any way. It's believed to exist because the movement of galaxies seem to be affected by a certain amount of gravity that cannot be accounted for by any observable mass.

This is all well and cool, but I'm kind of hoping there is no actual dark matter. How cool would it be if the source of gravity were not unseen mass but something completely unforeseen? Collision points with extra-dimensional universes? Some new branch of physics where very, very large bodies have their own rules, like the opposite of quantum physics?

I'd love to see the mystery solved, I just want the solution to live up to the romance of the problem.
