the world will end LONG before the galaxy could collapse in on itself.

The Sun is only going to last another 5 billion years, so when that happens, the earth will essentiually be swallowed up when the sun becomes a red giant. And if you think humanity is going to last even a million years, then we have a lot of work to do. Unless we start to spread out to other planets soon, I doubt humans on earth will be around very long.
