Longer term, it'll turn into a ball of stable iron, though, so the

I am not so sure about that..


Might end up as a supernova..

Very unlikely indeed, in the absence of a companion star to ours.
There isn't enough mass in the solar system even if the sun engulfed

Ah but when the universe does the heat death thingy, wont it all
collapse back, or does it expand infinitely into a sort of never ending

"They" don't know, and opinions differ.

the Cosmological Constant, whether it is, in fact a constant over time,
and the amount of Dark Matter.

I should have listened to Patrick Moore...

He says he doesn't know, either. HTH.

In a few more years, it'll be a an S.E.P. anyway. Unless the Buddhists
