Yes but it is consistent on Earth right? So that speed, a certain amount of feet a second, could be transfered into space. Its just not somthing they would normally do.

Um, I always thought it was taught in chemistry that hydrogen may take valancies of both +1 and -1.

Now I won't carry on with this discussion, because it's absolutely pointless! :) (Or unless someone else decides to carry on.)

"Mach"?...mach is a gauge of velocity relative to the speed of sound in atmospheric conditions; There ain't no "mach" in space--that would be an anachronism. (I seem to recall a promo line from some sci-fi space movie--perhaps "Alien": 'In space, no one can hear you scream'. That about sums it up)
