The Fredditlore Multiverse

The Multiverse is the conglomerate of all the Universes in canon. Each Universe is a timeline with its own concepts of space, time, matter, energy, information, physical laws and constants that describe them.
Although the Multiverse is infinite (comprised of every branching timeline), usually in lore when we say the Multiverse we refer to a section called the Finite Multiversal Curve, a part of the Multiverse accessible to the citizens of the T.B.C. A.N.A.L. Multiversal Conglomerate.
==The Fredditlore Multiverse==
The Finite Multiversal Curve (or the Fredditlore Multiverse, the Fredditlore Curve, the Curve, or sometimes just referred to as the Multiverse, even though it does not have every single Universe in it) typically has Universes similar to one another, that is, with differences in timelines but with similar physical laws: for instance, the presence of gravity, atomic structures, etc.
Beyond the Fredditlore Multiverse, the Universes get weirder and weirder, more different and more incomprehensible. No living being aside from Jeff the Securitron has traveled beyond the Curve. 
The canon stories occur within Fredditlore, hence the name. Should any story conflict with present canon, it's ruled that its Universe exists beyond the Fredditlore Curve, thus getting rid of any conflicts with already established timelines and Universes.
The weirder and more different the Universe is, the further it is from the Center of the Multiverse, also known as the Multiversal Capital. The A.N.A.L. Council controls around 98% of the Fredditlore Multiverse, with the remaining 2% being on the outer edges of the Curve.
==Universes==
Each Universe is attributed a designation by the A.N.A.L. MELEC Catalog (Multiversal Entities, Locations, Events and Creations Catalog). It's comprised of a name (IP) and a five digit number (PORT). For example, Freddit-25565 is the official designation of the Mainlore Universe.
The timelines in the Fredditlore Multiverse can vary wildly, but a lot of the same characters are present in most timelines. For example, Zoo Man is estimated to exist in 87% of all Universes in the Fredditlore Curve as different kinds of variations of his Mainlore counterpart (for example, Tiny Zoo Man, who is a Zoo Man the size of a football).
All of these Zoo Men are variations of the same being, and thus they share the same UUID (Universal Unique Identifier) assigned by the MELEC Catalog. The variations of the same entity are called selves.
==Entities in the Multiverse==
Conscious beings are classified as entities (or selves) in the Multiverse. They include Humans, robots, Spurrians, Cakepeople, and anything that is considered sentient.
The criteria for consciousness is simple in Fredditlore: if they have Secondary Balls, they are a conscious being. Every single sentient being has them - including Jeff the Securitron. 
Secondary Balls are theorized for being responsible for consciousness. The growth of Secondary Balls inside an entity seems to equate to the same time they become sentient. 
Note: the surgical removal of one of the two Secondary Balls seems to cause severe hallucinations, while removing both causes an almost immediate catatonic state. No entity has survived not having Secondary Balls. 
The presence of Secondary Balls is observed in robots as well. Some Securitrons and Psychanics are known to grow Secondary Balls. However, not all Artificial Inteligence is sentient. Zoocan ADA, the Cock-Boy virtual assistant, is not sentient and does not have Secondary Balls. TBCLABS-25565's most powerful supercomputer, CaSE, has not grown Secondary Balls despite its immense intelligence. In contrast, T.B.C. Lightbulbs have Secondary Balls and are conscious, confirming the theory that intelligence does not imply sentience.
Variations of the same self have the same anatomy of Secondary Balls. Their composition, molecular & cellular structure, form and anatomy are the exact same when compared. This is the criteria behind the definition of a "self".
When two beings from different timelines have the same Secondary Balls, they are confirmed to be variations of the same self, and thus must be assigned the same UUID by A.N.A.L..
Note: no two beings from the same timeline have the same Secondary Balls - even if they're clones, twins or exact replicas. This phenomenon has been confirmed time and time again. Clones and twins always have different Secondary Balls.
The UUID is attributed by reading an entity's Secondary Balls, the organ that exists in every single conscious being (including robots) that can be accessed by the T.B.C. Nipple Gun. Variations of the same self will always have the same Secondary Balls, making them the equivalent of a fingerprint of their self.
Example: Mainlore's Zoo Man and Filesverse's Zoo Man have the same Secondary Balls. Any Nipple Gun reading will reveal the same organic composite in both these entities. Comparing to the MELEC database, they'd both be attributed the same UUID, as they're a variation of the same self. Zoo Man's UUID is 2fa14272-2ac2-41ff-bb3b-f33c2499552d. Any variation of Zoo Man will have the same Secondary Balls and therefor the same UUID, assigned by A.N.A.L..
No matter how different, if two entities have the same UUID, they are variations of the same self. Even if they're different in name, species, age, gender, or any other attribute, if they have the same UUID, it means they are a variation of the same entity.
Example: Mainlore Zoo Man and Spurrlore-24442 Zoo Man are the same variations of the same entity (since they have the same UUID), even though Spurrlore-24442's Zoo Man is an ape-like gorilla with zero cognitive abilities and with terrifying urges of ripping people's skin off.
==Physical Laws of the Multiverse==
*Entities with the same UUID cannot have originated from the same timeline. This means if two beings have the same UUID, they must've come from different Universes. For example, the Mainlore Zoo Man and the MCEO Zoo Man have the same Secondary Balls, meaning they're variations of the same self. They cannot both originate from Mainlore, as by its definition a variation implies a different timeline.
*No particle can travel faster than FAST-8. F.A.S.T. (or Full Asynchronous Speed Transfer) measures the desynchronization speed of a particle. Beings utilizing Cock-Boy travel usually traverse the Multiverse at a FAST-4, while an above average speed would be considered at FAST-7. FAST-8 is the Apyr-Null threshold. Particles traveling faster than this threshold will become fully, irreparably desynchronized and their fate ultimately unknown, disappearing into thin air.
*No being can exist in the space between the Universes (unless they're inside a Death Chunk). This is due to the nine-dimensional nature of the Multiversal Gap. Molecular structures disintegrate into a nine dimensional shape if they step outside a Universal boundary. The only two exceptions to this rule are Hooplex particles which seem to originate from the Gap itself in the first place, and Jeff the Securitron because he's Jeff the Securitron.
*There can only be one Hyper-aware entity in the Multiverse. This rule has not been tested, verified or falsified. It was said by Jeff the Securitron. We're taking him for his word here.
*Time travel between Universes is not possible. Although it's possible for, in certain Universes, to time travel. This may be hard to grasp, but here's an easy example: if you are in 2019 in a Universe, and you go back to 1958, and you travel outside to another Universe, you pop up in 2019. This is because you never actually left 2019 - you just rewound that Universe's time to 1958 while it's still 2019 for every Universe around you. The only exception to this rule is Jeff the Securitron.
*Desynchronization is a dangerous phenomenon to sentient beings. This occurs when the Multiverse is misplacing your identity with other variations of yourself, and attempts to correct the issue by eliminating other probabilities. This means nearby variations start rapidly appearing and disappearing in your own timeline, as the Multiverse attempts to collapse your selves into one. However, this has the opposite effect, as now every move you take is mistaken for other variations in a positive-feedback loop, hence the term desynchronization. If this occurs, stand still and call T.B.C. emergency services. They can resynchronize you by utilizing a Cock-Boy. No matter how weird things get around you, do not move, as every move will desynchronize you further and further.
*To breach a Universal border into the Multiverse, you must puncture the fabric of space-time using Hooplex particles and continuously exert an incredible amount of energy to keep it open. This is because the space outside each Universe (called the Multiversal Gap) keeps all timelines contained and actively attempts to close any breaches. The Hooplex particles are required because they are the only ones that can travel in the Gap, and thus are the most efficient to breach the border. They're also used to keep the breach open.
*Death Chunks are wormholes between realities. They formed in the Great Cataclysm, although some have been artificially created. They exert continuous force against the Multiversal fabric to remain open. Their borders are made of trillions of Hooplex particles, pushing against the other trillions of Hooplex particles that come from the space between Universes (aka the Gap). When the balance for some reason is broken, and the outside Hooplex particles triumph, the Death Chunk is shut off. Terrain from the end point Universe falls to the entry point Universe, creating weird chunks of misplaced land, while at the end point a vacuum is created.
*Longer Death Chunks have a point of no return. If an entity has an uncontrolled descent into a Death Chunk, they may get past the point of no return. As they accelerate more and more, their FAST speed builds up. If they breach the FAST-8 threshold, they will be desynchronized past the point of no return and will vanish from thin air. This occurs even if the Death Chunk has a endpoint Universe (i.e., if it has an entry point in one Universe and an exit point in another). You will not fall safely in the other end. Only the Death Chunk's length and the being's time of descent matter - if it has an endpoint or not is irrelevant to this dangerous and lethal phenomenon. Do not jump into ANY Death Chunk.
