The End of Everything - NYTimes.com: If the present trend of acceleration continues this is the forecast:
In about two billion years Earth will become uninhabitable as a gradually warming Sun produces a runaway greenhouse effect. In five billion years the Sun will swell up and die, burning the Earth to a crisp in the process. At about the same time the Milky Way will collide with its twin the Andromeda galaxy, now about two million light-years away and closing fast, spewing stars, gas and planets across intergalactic space.
