According to estimates of the mass of Dark Matter, the universe may have a volume-specific mass about 6.5-times higher than that of visible matter alone. So if I apply this to my Black Hole Inflation Hypothesis, the radius for the event horizon of our universe is 6.5-times further away than the edge of the visible universe. Our visible volume then is just one of 275 such volumes within the bulk (geometric) universe. Although still causally connected, the redshift between each of these volumes is extreme, caused by the accelerating, perhaps even superluminal growth of a black hole approximately 13.7 billion years ago, which gave birth to the universe as we know it.
