My own personal theory, that I thought up while I was taking my daughter driving, is that the missing mass in the universe is contained in particles moving faster than the speed of light. Since their mass is imaginary, they are difficult to detect using traditional methods.
However, in my soon to be published reference work on faster than light science fiction theories (available for $19.95 plus $6.95 shipping and handling), I describe a 2nd order differential equation where the mass appears as a square. This explains the missing mass AND medved's Saturn origin theories.

You are groping your way toward the ultimate truth. TIME CUBE .
I'm probably going to regret asking this, but to what are you referring?
