That's just swell! The universe could end any time, although the odds are rather low really, but still what a thing to stay awake at night worrying about. After figuring out that the universe was expanding, cosmologists wondered if the universe would end in a Big Crunch, sort of a reverse of the Big Bang, or in a Big Chill, expanding outward forever. Then the discovery, sort of, of Dark Energy suggested that the universe would end in some sort of particle decay, a Big Rip, something that sounded rather like the show at Milliways, the Restaurant at the End of the Universe. But no, the universe will end up being gobbled up by an expanding bubble of alien (to this universe?) energy, a Big Gulp. What to do?
