Today I finally got around to looking up "the power cosmic". You see, my roomie and I have had several conversations with people about the silver surfer and whether he could beat X superhero, and they always go, "But, he weilds the power cosmic." But no matter who it was, they could never exactly say what the power cosmic was or how it worked, only repeating the tautology "but it's the power cosmic".
The first several descriptions I found described it as, "the ability to control the four elements of the universe, giving the surfer a variety of powers"...
But what does that mean?!?!? Nothing! It sounds like something some stoner came up with on some trip -- and that trip was an acid trip.
Finally, we found a more difinitive description. I am now satisfied.
