Query: Primordial Black Holes in Phantom Cosmology   We investigate the effects of accretion of phantom energy onto primordial
black holes. Since Hawking radiation and phantom energy accretion contribute to
a {\it decrease} of the mass of the black hole, the primordial black hole that
would be expected to decay now due to the Hawking process would decay {\it
earlier} due to the inclusion of the phantom energy. Equivalently, to have the
primordial black hole decay now it would have to be more massive initially. We
find that the effect of the phantom energy is substantial and the black holes
decaying now would be {\it much} more massive -- over 10 orders of magnitude!
This effect will be relevant for determining the time of production and hence
the number of evaporating black holes expected in a universe accelerating due
to phantom energy.
