I took a second look at my cosmology, and I realize that I made a tremendous mistake when I dismissed my original theory about the possibility of paired universes due to the fact that I couldn't make a stable system out of that setup.
It was, of course, a fundamental error on my part to assume that interuniversal stability was required of the multiverse. The known universe is unstable everywhere, so there's absolutely no reason for me to have rejected my original theory on the basis of the unfounded and unnecessary assumption that stability was required within interuniversal space.
This reasoning also partly contradicts Professor Marsini-Houghton's "hotel room" concept, as, although each universe must begin on its own energy point ("hotel room"), there's nothing that necessarily prevents the guest in the next room from digging a hole through the wall into your room. In other words, universes may collide.
Very embarrassing for me, a guy who prides himself on his clarity of thinking, particularly as I'd already discussed the possibility of the motion of universes through interuniversal space, seeing as motion itself is necessarily the result of instability
Therefore, I've rejected my new forulation, and have revised my original one: that the distribution of universes in interuniversal space is non-uniform, which fact does not preclude the possibility of the pairing of universes (i.e., a level of orgainisation intermediate in scale between the universe and the multiverse may exist).
Hope I got it right this time!
