This is not really a multiverse question, but rather a common query
relating to relativity and QM. See question 6 in part 2 of the
sci.physics FAQ, "How does the gravity get out of the black hole?", at:

The short answer is that when you model forces as the exchange of
particles, it is actually done as the exchange of virtual particles;
and virtual particles can go faster than light, hence can escape from
black holes.
