I'm not a cosmologist, or even a physicist. I'm trained in civil engineering, but have a profound compassion for astronomy and the cosmos. But...

My question to the board is this. Is it possible that the two ends of the spectrum that define the infinite number of universes some theorize would include our known universe, and that of the exact opposite of what we perceive? That is, the other extent of this spectrum would include a universe comprised almost entirely of mass, and very little space. Like a massive piece of Swiss cheese, where the holes would be where objects with mass are in our universe. Kind like a multi-dimensional negative of the universe we see.

In this opposite universe, gravity is not an attractive force, but a repulsive force. The big bang would have been a big squeeze; black holes would be emitting huge quantities of mass like giant white exploding stars. The sum of all the universes would then be bound on one side by our known universe, and the "negative" of our universe, with an infinite number of "partially" negative universes in-between.
