The Fate of the Universe (as told by Wikipedia)

The universe is expanding. The universe looks (from our vantage) like it's expanding in every direction. No, we're not the center of the universe. It's like we're a raisin in a ball of rising raisin bread dough.

Even more creepy... The expansion is accelerating. It's as if the vacuum of space has a magic force that acts to push things apart, and is stronger than gravity over great distances. As the gaps get bigger so does the vacuum energy. So one day the universe will rend itself apart.

But don't let that prevent you from sleeping at night. The universe will have used all of the high quality energy leaving only borderline useless heat energy. Burnt out pulsars, black holes, frozen planetoids, and other bits of deary randomness will be all thats left. But before that the sun will have long since swollen up; either cooking Earth to a crisp or cooking it and then eating it.

That might be a blow to the positive thinkers in the crowd. Cheer up! This may not be the only universe around.
