you saying the sun is a star and like a light bulb has a certain life

http://map.gsfc.nasa.gov/m_uni/uni_101stars.html gives a decent
explanation of stellar evolution - the gist is that, in a few billion
years, under current theories, the sun will extend to somewhere around
Jupiter. Probably a good idea to have moved out the neigbourhood by
then, if we're still around...

Fascinating,

Thanks for the links and info, much to read. Do we have a plan of escape in place
or is it sort of like cross the bridge when we come to it? I mean it's like give or
take thousands of years right? That's allot of lives.
