Default Question about Hawking Radiation



I read Kip Thorne's description of Hawking Radiation, but it seems
incomplete. He says that when particle/antiparticle pairs spontaneously
emerge in the space near the event horizon, sometimes the anti-particle is
sucked into the black hole and the real particle excapes into space, which
is observed as radiation. The captured anti-particle enters the black hole,
and consequently reduces the mass of the black hole by the exact amount of
mass that escaped into the surrounding space. My question is, why wouldn't
the real particle be sucked into the black hole just as often as the
antiparticle, thus offsetting the loss of mass on average over time?

TIA

Good question - and it made me look it up.

Whether an particle or an anti-particle is emitted is irrelevant - Since
they both have 'positive' mass it doesn't make any difference which type is
emitted.

With real mass being created from virtual energy in the vicinity of the BH,
the BH has effectively lost mass-energy.

The overview on Wikipedia's article explained it to me.
