As I mused a few years ago in another document, rotation seems inevitable. Not rotating is just a unique case of rotation where the angular momentum is zero. Why would that be favored? It’s unlikely because with zero rotation, the axis of rotation is undefined. That means there are infinite axes along which rotation could happen. Infinite opportunities for instabilities.
Working off the concept that momentum is fundamental to our world, the simplest momentum is angular momentum. If our universe (multiverse) rotates in some way, it explains entropy and the single observed direction of time. Reversing time would mean reversing the angular momentum of the universe.
This restricts my assertion that the total momentum of the universe is 0 to the total linear momentum of the universe is 0, unless the universe is a paired system (or system of paired systems) with counter-rotating parts. This gives total angular momentum of 0 and total time of 0.
The universe is a 3D surface in 4 dimensions. The rotation must be a higher dimensional phenomenon. Recognizing it from a 3D point of view might be difficult. However, the angular momentum would have to appear in our perceived universe as energy somewhere.
