What is Aleph Null?
This is an alternate universe. It is a canon adjacent thought experiment, the base of which is Homestuck's Alternia. It takes the known basic concept from canon and fills in blanks. It makes logical hypotheses about how a functional Alternian Empire would work. The question was proposed:
What if sburb never happened? What if Alternia were to be dropped into a science fiction galaxy with other alien races?
As a result there are different rulers, different ways the empire functions and is heavily cyberpunk and sci-fi based. The latter is because as the brain behind this AU I love both of these genres and Alternia in canon was already heading that way.
Why Is it called "Aleph Null" ?
Aleph Null or ℵâ‚€ is the first smallest infinity and it is the cardinality of the set of natural numbers. It is not a real number and it is not naturally occurring. Just like this AU, it technically does not exist, even though some concepts may seem real or logical. It's sort of like a "Schrodinger's AU" where things could exist but it also canonically doesn't. Not to mention the fact that this AU is one of an infinite number, there are probably a vast amount of people out there with alternate universes of their own, this is just one of many.
