The Universe is a series of Tubes

I just read about a really fascinating theory that there are points in space that exist that the exact opposite of black holes. This theory came about after recorded bursts of random gamma radiation and the sudden appearance of new stellar objects in that point of space. Apparently, it is a point in spacetime that expels light and other objects which makes it the opposite effect of black holes. What if black holes were not the purely destructive force that we view them to be now? What if those black holes were just a hole in space time that leads to another point in the universe. That could possibly mean that black holes at the center of most galaxies doesn't eventually destroy it but merely moves it. Some strange theories surround this topic matter like the one that suggests that a big bang occurs whenever a black hole is formed and creates a separate parallel universe off of the parent universe. None of this can be tested of course seeing as the gravity of black hole's event horizon would theoretically rip apart anything that got near it's event horizon and that isn't even mentioning that fact that the a singularity occurs near that point which ostensibly slows down the flow of time for the object nearing. The gravitational fields of those things is massive but none of it can be really proven. It is interesting stuff regardless.
