Ultrastasis
This is one of the most counterintuitive concepts in null physics; even more so than the summation to zero, because change is overwhelmingly manifest whereas our universe's composition at the level of infinite smallness is not visible.
The premise here is that the universe, in its entirety does not change. The local change we experience is just as real as the material in which the change is obvious. This, and the full extent of what we call 'reality' is available only because we are a part of the system, within the universe. So now take that whirling galaxy. It is a tiny bit of the total universal pattern, and it is reasonable to think that if we could be outside of the universe looking at this tiny bit, change would be evident. However, outside of the universe, this galaxy simply does not exist, nor does anything else. Existence is contextual, so it is not possible to make any comparisons across the summation to zero.
However, we can, from within the universe, compare the local universal pattern of an hour or billion years ago with the current pattern, and they are clearly different. If you extend this comparison to infinite distance in all directions, an interesting thing happens. The volume where you are performing your comparison becomes infinite, before you reach the entirety of the universe. In other words, the universe's volume is inf^3. It is so vast that it contains an infinite number of an infinite number of infinite volumes. Null physics refers to this property as ultraunboundedness. Once infinite volume is reached, it is no longer possible to do a direct one-to-one comparison between any two patterns, because they have no edges. In short, three-dimensional space is so large that it is big enough to contain its own history.
The other way to look at ultrastasis is that it is inevitable in any context. Even if our universe were flowing down some additional dimension of time (which it is not), this space-time construct, when taken in its entirety, is static. There could be any number of universes flowing the same direction, (there are not) but the total system would be static because each state is present from one moment of this gestalt 'space-time' to the next. So the difference between this inevitable stasis and ultrastasis is that the universes flowing through time, from state to state, are much smaller than three-dimensional space (omnielements versus omnipattern). Ultraunboundedness allows these vast distributions (moments) to move inexorably from one state to the next, clicking along.
If there were no causal relationship between omnielements (moments), three-dimensional space would be too small. In other words, in the absence of causality, where matter and energy could be distributed into space in any permutation, inf^3 is not big enough to hold them all. However, since states are determined by pre-existing states (and so on), causality reduces permutational variability so severely that our universe is large enough to contain its own history.
I wouldnt dismiss it based on what I have read so far on this forum. Even Einstein made some mistakes and look what he produced.
