Virtual particle production beyond the event horizon.

  1. Apr 19, 2012 #1
    Good morning. I am wondering what is the nature of virtual particle production beyond the event horizon of a black hole. When a particle-antiparticle pair is created from the vacuum, it takes time for them to attract electromagnetically and annihilate; but since the event horizon separates space-time into two different regions (time even stops there I believe), how do quantum processes get affected by the intense curvature created by the black hole? Space is falling inward much faster than light + time has stopped, so technically nothing even has time to happen. What is going on?

    CarlosLara, Time does not stop inside a black hole, or on the surface. What happens is that the outgoing photons become infinitely delayed. Locally however the spacetime is perfectly normal. If you consider the usual Schwarzschild coordinates r and t, inside the hole they reverse roles: r becomes the timelike coordinate and t becomes spacelike. A falling particle experiences a finite elapsed time before it strikes the singularity.

    When a virtual particle-antiparticle pair is created beyond the event horizon, space will drag the pairs as soon as they are created, thus making them real before they annihilate (it takes time for the two particles to exchange virtual photons in order to mediate the crucial electromagnetic force associated with their respective charges). Space can do this by being energised by the mass of the black hole to the point that space falls inward faster than light. Therefore, the black hole should absorb all of the dark energy contained beyond the event horizon into its singularity, assuming the speed of the dark energy particle agrees with the speed of light. Where is all of this energy going? Somehow it seems that any amount of energy always fits in a very small dimension.

    CarlosLara, Everything you say is nonsense.
