Many interesting things happen when black holes collide (at least
theoretically). One is that the final resulting black hole has an apparant
volume less than the sum of the apparant volumes of the two colliding holes.
As for particles being pulled in two, it wouldn't happen. Quantum fluctuations
alone would ensure that the particle went one way or the other. Then again, in
an area of such extreme gravitational stress one would expect to see lots of
spontaneous pair production, one particle of each pair being sucked into each
Finally, there was an interesting science fiction short story in which one
researcher was extracting information from micro black-holes by colliding them.
She was (somehow) intercepting infinitely red-shifted photons that were being
pulled out of one hole and falling into the other, at the exact moment when
their event horizons touched.
