Results

• Solution for a stationary accretion of the
  relativistic perfect fluid with an equation of
  state p(?) onto the Schwarzschild black hole is
  presented.
• Accretion of phantom energy (?plt0) is
  accompanied by the gradual decrease of the black
  hole mass.
• Masses of all black holes tend to zero in the
  phantom energy universe approaching to the Big
  Rip.
