The name of this post should be "What? The sun could last forever?" instead of what I typed.
I was randomly looking around on the web and I came upon a question on "wiki.answers.com" that asked "How long does the sun have left?"
The top part, I knew, but that bottom part intrigued me. I've never heard of this experiment. How can the life of the sun be infinite? I'd imagine that it wouldn't be looking anything like it currently does in a few billion years. Anyone here know of this theory and care to elaborate? My instinct says that it's nonsense, but then again, I'm not a physics expert so I decided to ask here about it.

The responses is: "Nobody really knows, since we haven't been around long enough to observe the entire life cycle of a star. By putting together clues from the stars that we can observe, I've seen estimates that range from 6 billion to 10 billion more years, based on an age of 4.5 billion years so far. Stars are apparently fairly short lived, compared to the galaxies in which they are formed and live out their lives. If the sun was a very large star, it could have been gone long ago, as the bigger the star, the faster it burns up its initial fuel, so that some stars are done in only 10 million years! Ours is probably going to be around for a very long time to come.
Edit: Through the use of modern un-melting magnets, estimates have shown that the suns life span can be infinite."
