black holes - Hawking Radiation and virtual particles


Why is energy/ mass taken away from a black hole? Doesn't the energy coming from the virtual particle come from the vacuum energy? ...if this is so, why does the black hole have to pay the energy debt?


If the black hole creates the particles by its energy, what energy was used from the black hole to create them?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
