Astronomers freaking out, again. There's a reason, you know. You wouldn't want everything running into each other and eventually imploding, right? I've got one of those duds in my basement now. I've no idea how to turn it off! Boom - a Big Bang - then it stretches so far before it starts collapsing in on itself - then - Boom! - and the whole thing starts all over, again. There's no ESC button. It's very annoying.
So, deal with it. The main problem anyone left at the end will deal with be the how to forestall the inevitability of heat death.
