The Sun has been active for approximately 4.6 billion years. However, it only has enough fuel to go on for another five billion years (Y5B). At the end of its life, the Sun will start to fuse helium into heavier elements and begin to swell up, ultimately growing so large that it will engulf the Earth. Life on earth will change as we know it. First we will have mildly warmer temperatures, then a heat wave will be with us, and finally it will get cold....real cold. Thus, the Year Five Billion will be here. Will we be prepared for the billionennium(tm) bug ? Y5B.com will try to help.
