Haven't you heard of the Big Rip Theory? It seems that several

That's extremely speculative at the moment. Mainstream thought has the
Universe simply cooling forever.


If this theory is true then it does put an upper limit on how long the
Sun will remain in the white dwarf stage. I suspect that if this
theory is true the Sun will have cooled so it no longer appears white.

Depends on what you mean by white. In 20 billion or so years, the Sun
will still be very hot and certainly glowing brightly.

It seems a logica consequence IF the expansion is accelrating. At
somepoint it should overcome even gravity. Of course who is to say
the accelration will continue forever. I am certain someone will come
up with a new theory in other decade or so.

By white i was referring to the color. I am sure it will still be
bright, but I am thinking it may well be yellowish after 20 billion
years.
