Is there vacuum at the Event Horizon of a Black Hole?

  1. Nov 29, 2014 #1
    As all of us know that in a vacuum the particle antiparticle pairs or the virtual particles are created violating the law of conservation of energy.

    So even near an Event Horizon of a Black Hole virtual particles are formed. One of the particles gets sucked into the black hole but the other remains emitting a radiation called Hawking Radiation.

    So is there vacuum at the surface of the event horizon due to which particle antiparticle pairs are created?

    Yes, but there are vacuums and there are vacuums. Ask what the mean free path might be near the horizon.
