Understood. But what about another black hole?

Has anybody got an insight on weather this is possible?: If two black holes of a similar size were attracted to each others gravitational pull, would the effect on the light absorbed by each black hole be negated for any period of time? If so, what would we gain from this knowledge? I read somewhere recently that if a human was able to reach a large black hole, one which is large enough to have its effects on passing its event horizon were slowed way down, then that human would be able to see everything that ever has or ever will be sucked into the black hole, including things from the beginning of the universe, because of the speed you are travelling and its effects on time. Would there ever be a use for creating a particle with technology such as the LHC, that is that massive, that we could use it to affect a black hole? Thought and opinions please.
