To start off, put yourself into the "shoes" of one microscopic plankton in Lake Superior . All this entitiy experiences is the Lake. To try and make this microscopic planton fathom the experience and existence of Land or of Outer Space is impossible. Now what does this have to do with Black Holes? We humans are very small compared to the vastness of the Outer Space. Just like the vastness of the Lake the microscopic planton sees, we see the vastness of space in the same way. Conventional thinking is that there is only a vast Outer space, with relatively few concentrations of elements in their own concoctions. What if black holes brought us to the "land" that the plankton can't experience due to its microscopic nature. What if there's a type of cosmic vastness that isn't outer space or anything we have ever fathomed?
Maybe our perception of THE UNIVERSE, ALL AND EVERYTHING IN BETWEEN is just one "Lake" of Outerspace, when there is all this "Land" and other "Lakes of Outer Space" to explore, and to find the "ocean" of outerspace...
Are you following? It's hard to describe the "land" and "Ocean" when all we know is this "lake", just like that microscopic plankton can't describe the land on earth... Maybe Earth is just a minute fractal of the Cosmos... Maybe some black holes lead to the "land", while some get us to different corners of our "Lake" Check this video about Black Holes by Carl Sagan http://www.youtube.com/watch?v=Y-db4iC0aHw
