As I said, "suspension of disbelief", you either accept the idea or you don't. This particular line doesn't work for you. I don't have a problem with it. And to engage in "realism" arguments against it, when one could engage in any number of "technobabbleiean" rationals for it, to me, is unnecessary. You either accept this particular idea...or you don't. I do. You don't. It is that simple. No one else is required to measure this according to your own gauge. I would be ecstatic if this was the worst "problem" of this film, which it is plain it is not.
