Olliversan Multiverse model

The Olliversan model of the Multiverse is an explanation of the structure and functions of a universe, the Multiverse, and general fiction, as well as the interrelation between the three. It was developed by a large number of Olliversans across several universes and unified and generalized by Hypercube Organizations. It was developed in order to safely travel the Multiverse and intends to unify concepts of the Multiverse and general fiction, taking into account the latter's strong influence on the former.

Due to the Multiverse's incredibly dynamic nature, the Olliversan model is among several other models of the Multiverse.

Definition of a universe
The exact boundaries of a universe remains unclear. The Olliversan model describes a universe as a self-containing collection of matter and energy that is under the influence of the same time and space. The reason for the difficulty of describing a universe is due to the diversity of universes in shape, size, and content.

The size of a universe and how much matter it contains varies from universe to universe, and it depends on how much of the universe can be accessed, let alone observed. It is understood that a universe is extremely large and extremely massive. The specific physics in each universe may also vary. A universe is entirely contained within an “ububble” [uh-buh-bol] that is smaller from the outside than it is from the inside.

Some universes divide all of its matter into smaller subworlds, also known as dimensions or realms, which are self-containing collections of matter which themselves are contained in a universe. The properties of these subworlds in each universe greatly vary, making it impractical to generalize the subworlds of all the universes, so the concern of subworlds fall under their respective fields of study in each universe.

A universe has several timelines. A timeline is an ordered set of events that have occurred in a universe. The reason a universe has several timelines is because timelines can branch from other existing ones, which all trace back to the sacred timeline, the timeline that is not a branch of any other timeline. Determining the sacred timeline is difficult, though it is typically the timeline that an exouniversal entity experiences first upon entering a universe. The concern of timelines fall under their own field since their overarching nature is usually not important to the study of the Multiverse.

There are three main ways universes are created:
 * Spontaneous creation — there is no explanation for this.
 * Divine creation — An entity with immense power may have the capacity to create entire universes. This includes the beings from the Upper Reality.
 * Universe derivation — The matter in the universe doubles, then divides into two identical universes, each with their own ububble. One of these two will transform radically in such a way that the original won’t.

Universes can deteriorate (or ‘die’), and upon doing so, leave behind their ububble. Universes can die through natural decay or to the hands of a being with enough power.

Basic movement of universes
There is an innumerable amount of universes. Most likely this was decreed by a being from the Upper Reality. This collection of universes is known as the Multiverse, which is thought to be boundless.

Universes may either be found in groups known as universe clusters or wandering alone. A universe cluster may contain a countable or innumerable amount of universes, and a universe may be a part of multiple universe clusters. Though not always the case, the universes within a universe cluster may share multiple characteristics such as physics, inhabitants, and concepts, though determining these shared characteristics is difficult without resorting to intuition.

Universe clusters are typically formed naturally, though their formation through divine intervention has been witnessed several times. The movement of universes in relation to each other wildly varies among each universe cluster. Some universe clusters may follow an orbiting system, while others remain mostly motionless. Chaotic movement and artificial order of movement has also been observed.

Two universes can bump into each other. This bump is known as a crossover. When a crossover occurs, some matter from both universes doubles and transfers over to each other. On a living scale, this amount is a very high amount, but on a universal scale, the amount is not much. In extreme cases, two universes may collide and fuse with one another. This event is known as a fusion. In this event, the ububbles of the two universes combine into one, and the matter from both universes “mix” together. The result is a single universe that has the combined volume of the previously separated universes. Both crossovers and fusions occur very rarely.

On Reality, the container of the Multiverse
The Multiverse is contained within a reality, though it is usually referred to as simply ‘Reality’. The beings of the Upper Reality call it ‘Fiction’. Also contained within reality is the Fourth Wall, an impenetrable barrier separating Reality from the Upper Reality. The composition of the Fourth Wall is indeterminable, but is thought to be as tall and wide (or is it long and wide?) as the Multiverse is. Anyone within Reality cannot see through the Fourth Wall, but it is speculated that the beings from the Upper Reality can see through the Fourth Wall and even influence universes from behind the Fourth Wall.

Universes containing popular media from the Upper Reality are noticeably closer to the Fourth Wall than those containing more obscure media. The popularity of a universe is measured by its frequency of observation from the Upper Reality, as well as the number of active memories about a given media. This is the basis of the Popularity-Based Concentration (PBC) theory. The theory states that the concentration of universes increases as distance increases from the Fourth Wall, as there is more obscure media than there is popular media.

As the popularity of a universe increases, its distance from the Fourth Wall decreases. The inverse is true; an unpopular universe is far away from the Fourth Wall. The movement of universes in relation to the Fourth Wall is greatly affected by events in the Upper Reality. For example, before the Internet became a highly used system, movement to and from the Fourth Wall was highly frequent. As the Internet rapidly grew, universal movement further tended towards the Fourth Wall, with some obscure media even seeing a resurgence. That being said, there are still a number of universes drifting away from the Fourth Wall.

An obstacle preventing the PBC theory from further flowering is the increasing uncertainty of the number of universes as distance increases from the Fourth Wall. Dubbed the ‘Great Unknown’, this area of the Multiverse is largely unexplored and the number of universes remains uncounted. Either there are a staggering number of or barely any universes, and it remains unclear because it is not known how much extremely obscure media there are.

Also unknown is the fate of a universe when it is no longer remembered whatsoever. Forgotten universes may be subject to immediate deterioration, but this has not been observed to happen. There is a rumor across the Multiverse that further away from the Fourth Wall can be found a being of infinite size, consuming universes that have been truly forgotten, even from the subconscious of an Upper Reality being. This being distant from the Fourth Wall is dubbed the Devourer of the Truly Forgotten. This is, of course, speculation, and should not be seriously regarded.

The idea of an alien Multiverse
So far, beings observed in the Upper Reality are humans; these humans watch and remember media associated with universes in our Reality. Although it is common knowledge in a high number of universes that humans are not the only sentient beings (and some universes even lack humans), other universes with humans continue to question the presence of intelligent alien life.

In a similar fashion, the humans in the Upper Reality are still largely unsure of whether there is intelligent alien life in their universe or not. In fact, most non-Earth entities found throughout the Multiverse, while indeed “alien”, are very similar to entities found on Earth. This is because it is simply not possible to think of something completely new without taking inspiration from pre-existing information, which, for the humans of the Upper Reality, is based on what is found on Earth.

If, however, intelligent alien life does exist in the universe of the Upper Reality, then it is possible that they may have their own forms of media and so have their own equivalent of Fiction. An idea is that alien-created fiction exists alongside human-created fiction in the same Reality. Alien-created fiction would, however, exist extremely far away from human-created fiction.

All of this assumes that aliens do exist in the universe of the Upper Reality. There’s an equal possibility that those humans are alone in their universe. For this reason, the existence of fictozones cannot be determined.
