Hi:

When the sun becomes a white dwarf, approximately how long will it
take for it to cool off to a cold black dwarf that does not emit
anymore heat or light [or other energies] than the surrounding space?


Thanks,

Hasn't the recent discovery that the Universe's expanse is
accelerating put an upper limit on the lifetime of the Unverse? Or at
least the lifetime before every particle is froced apart from al te
particles? Of course I'm sure that with in another 20 years someone
will make another discovery which will throw that model out as well.
