The process of black holes colliding and merging has been studied a
good deal, mostly by computer models based on General Relativity. You
could say that a black hole is already a sort of tear in the space-time
fabric, but if I understand correctly, no really new effects come out
of the collision of black holes. However, the resulting gravitational
radiation might be measurable, which would be pretty exciting.
