Question:
Will the sun ever burn out and if it will do you know when it will?

Replies:
Yup. About 5 billion years from now, according to our best theories of the way stars get older. The first thing it will do is expand the outer surface of the star, probably to close to the earth's orbit, which will be pretty much the end of things here.
