The sun is not infinite, when it runs out of fuel it will be gone too.
Wouldn't it already be annihilated by photons from the sun?
It's a tempting thing, given the sun will eventually burn out.
Lets hope it doesn't dim our sun...
Then nothing is, as the sun will burn out at some point (since we are nitpicking :) )
Indefinitely? The sun will eventually blow up.
Would a run away reaction turn earth into a sun?
Interesting how he predicts the reason for Sun demise.
Well, our sun will eventually explode, which will certainly chew up the biosphere.
The Sun you mean is now a white dwarf inside a black hole. If you want to know when you might find closure, you need to ask an Oracle ;-)
