Ooooo, I was a little confused there. Beshides, I think B5 or Halo is the most likely to happen to the human race. I'd rather have Halo happen, I'd prefer a to fight an enemy that I can kill at least. In B5, the Mimbari were basically imune to evrything the humans had except nukes. In Halo, humans could kill the Covenant with some ease because of the MAC guns. On a side note, the Magnetic Accelarator Cannon is actually possible to make, but on a small scale, you need super huge magnetic coils to fire the shell, there are few magnets that large from my knowlege.
