Jebrim. You keep saying how "you can't foresee anybody doing this", or how "nobody has ever done this before". I'm pretty sure most of us don't disagree. This is theory, just like how infinite money or cannoning cave crawlers for effigies is theory. None of these things are realistic, but technically, they're possible. For these time calculations, whether or not someone has done this is irrelevant. Whether or not someone will do this is irrelevant. It's whether or not it's physically possible that matters.
