Did you perhaps quote something? That's the ending code for quotes.
Assuming those names are of separate unique universes rather then timelines of something else:
That seems more like each unique universe branches its own timelines. Still Iow 1-C, however.
And assuming they are branched timelines of some other universe and they themselves branch the same way further, that at least implies a 1-C 6D via an Aleph-1 x Aleph-1 amount of 4-D timelines.
This was my train of thought
spacetime itself has a power set of 2 aleph-0, since that's the cardinality of a continuum.
Which if every coordinate in the universe of both space and time were creating uncountably infinite timelines wouldn't that lead to a space with cardinality 2^2 aleph-0?
Also I don't remember what I was trying to quote
Edit:
3D space is infinite, and the wiki assumes the 1 dimension of time to be infinite as well.
What's important to know that in the spacetime continuum everything is moving through coordinates in both 3D space and the temporal Coordinates. Everything I'm Saint Seiya is constantly in motion even atoms through naturally occuring solar cycles and atomic vibration. And as we see in the same quote the universe has a uniform natural progression of time as all things die through the progression of time.
Now if we took the 3D+1D space time continuum and pause everything in it. You would see 1 snapshot of the Timeline at that moment it was paused in. By wiki default assumption the universe has at minimum an infinite # of Snapshots of the 3D+1D timeline unless there is contrary evidence.
Now with that information, we know that the Saint Seiya universe is infinite and with it, there exist an infinite # of stars. By that we get an extension of an infinite # of atoms, Galaxies, etc. If we took 1 snapshot and pause the universe. We would then have uncountably infinite branches for that 1 snapshot as the same reason in the other section of this crt.
Now extend that to infinite snapshots.
Putting it far more simply
For every coordinate in 1 snapshot that an atom exist on (which is infinite coordinates) you get uncountably infinite timelines.
Thought this sounded like a better explanation
