All the war talk got you down? Well, consider this. Robert Caldwell at Dartmouth University has proposed the death of the universe 20 billion years from now in The Big Rip. The Big Rip is so named because something is causing the universe to expand, and if the effect were to accelerate, it would eventually rip apart not only galaxies, but matter itself. So now cosmologists have three models of the end of the Universe – The Big Rip, the Big Crunch, and the Cold, Dark. Cosmologists are really a happy, jolly bunch of people, aren’t they? So I hope this gives you a little perspective on your problems. 

Still worried? If the fate of the universe is a little abstract consider the Earth itself is going to boil away in just five billion years. Happy now?
