Just a name for everything, for the all encompassing set. It is in our nature to name things and this is a name to include all names.
Whenever one talks or thinks about anything that thing is inside it. No exceptions. It represents the top most level of ThisWriter's Cosmology as defined here on this wiki.
It has been referred by many other names like Reality, Omniverse, The Box, etc., but here the name Omniumverse was chosen. These names may also plausibly refer to things that have been named differently in this Cosmology.
Reality vs Fiction
There has been an attempt to define the Omniumverse in a way that actually makes sense with our True Reality as well as with any imagined or fictional one.
Structure
It is divided into two parts: the Realium and the Imaginarium. But like with everything else, whenever people see a division in two they also see a barrier or a border between those two things. This border will just be called the Great Barrier.
The Omniumverse is then divided into three parts: the Realium is all that is real; The Great Barrier is the border or division between reality and fantasy; Finally, the Imaginarium is all that is not real to some extent.
One could try to continue this reasoning: what is the border between the Realium and the Great Barrier and the Great Barrier and the Imaginarium? Doesn't that mean that there are 5 parts then and so on up to an infinity of parts? Well, those borders can all be collapsed into the Great Barrier itself as they are just more borders upon borders. But this argument can be used to demonstrate that the Great Barrier is infinitely thick and infinitely variable.
Inside the Imaginarium there are the Imaginata, the worlds of fantasy and belief. Put into context, things like The Box are either part of one or several Imaginatas or are equivalent to the Imaginarium itself but hardly ever the same as the Omniumverse. Names like Reality are probably synonymous to the Realium.
It is not possible to stand directly inside the Omniumverse and nothing else. This is probably easily explained by some analogy. Imagine a house: it has rooms, maybe a hall or two and walls dividing all the rooms and halls. For this purpose lets consider halls to be just another type of room. So a house is consisted of rooms and the walls between them. One cannot be inside a house without being inside some of its rooms. This is exactly the same with the Omniumverse. The Realium and the Imaginarium are its rooms and the Great Wall is the dividing wall. It is not possible to be inside the Omniumverse without being inside one of its rooms, either the Realium or the Imaginarium, or possibly even in the Great Wall that acts as the division between them.
How it relates to its inner structures and how they relate to each other
At the same time as it contains both of its constituents, the Omniumverse is also part of each of those. Both parts, both the Realium and the Imaginarium contain the whole in some way. It is being imagined by this writer, therefore part of the Imaginarium but again, by all evidence, there really exists a distinction between reality and fantasy, therefore the Omniumverse must be real as well, therefore part of the Realium.
Finally, each part is also contained in the other. The Realium contains the Imaginarium and the Imaginarium contains the Realium but these relationships are explained in their corresponding pages.
These two relations make said structures equivalent to the Omniumverse in scope.
Comparison with other structures
As stated before the Omniumverse contains absolutely everything without exception. This means that it is usually the top structure of any Cosmology it is in. It probably defines the Cosmology as well.
This will make it equivalent to the Box as long as the Box is also accepted as being a top level structure.
On the other hand, the Omniumverse remains a top level structure even if the Box is no longer considered to be so. This means that if one accepts that the Box can be transcended, accepting the existence of things outside of the Box, the Omniumverse will still contain all of those things somewhere, probably in the Imaginarium, turning the Omniumverse into a Ultrabox and, probably, a Metabox as well.
The Omniumverse is always a top level structure, unbypassable in any way and containing everything. Those are the fundamental aspects of its definition. Whether or not the Omniumverse is considered to be metaboxial does not depend on itself but on how one sees the Box and its proper position and definition.
Arguments for other structures or larger things
One could theorize about the existence of other things other than the three presented here or even things larger than the Omniumverse itself. Some examples will be presented next and shown why they fail:
It is always possible to imagine something bigger than the Omniumverse, something encompassing it. That argument is self-defeating in itself. The key word "imagine" guarantee that that something bigger is just another Imaginata, part of the Imaginarium. Verbs like conceptualize, theorize, think, create, define, etc are all similar to imagine in that sense. They all describe an intellectual activity which guarantees that their result is part of the Imaginarium. All other such similar arguments are the same: something larger is either real and part of the Realium or not strictly real and part of the Imaginarium.
Nothingness, non-existence, that which does not exist either in reality or imagination. Well, if it doesn't exist it is not real and is, by definition, part of the Imaginarium.
Even if one imagines something that is neither real and not real or something that is both at the same time, something that transcends definition, something that cannot be named, something that transcends transcendence, something that is larger than itself or whatever words one wants to use. Things that paradoxical in nature and even not paradoxical at the same time. All those things are part of the Imaginarium for, even if they cannot be directly imagined, they are still fantasies being referenced indirectly by the use of imagination. The same can be said for things to which the question of them being real or not real has no meaningful or sensible answer, no answer at all or maybe it can't even be posed in relation to those things.
One could also point out to all those things that are impossible to imagine by anyone in any way. Those things can either be real or not real. If they are real, which is doubtful, they are part of the Realium. If they are not real, even if not imaginable, they are still part of the Imaginarium for not being real. And even that which cannot be imagined is, through that title, being referenced indirectly by the use of imagination. Therefore they are always part of the Imaginarium anyway.
Another argument that is always easily made is that if there is some definition of a space, what about what lies outside of that space? Well, choose: either there is no outside of the Omniumverse, it just doesn't exist, it has no limits or borders; or its outside exists inside the Imaginarium, therefore, also inside the Omniumverse itself. Both options are equally valid and probably identical. Seeing that people continue to try to imagine some outside for everything the second option is probably stronger than the first.
An argument similar to the previous one and with the same conclusion is what about things that don't have a location, things which are not located anywhere at all. Or things which are not and/or cannot be contained by anything or inside anything. Just like everything else those things are either real or not real, therefore they are either in (or part of) the Realium or the Imaginarium. The absence of location is something that exists neatly inside the Imaginarium, as is the absence of containment.
There exists an argument of complexity, that things cannot contain other things that are more complex than themselves. Well, the three single things directly contained on the Omniumverse are all more complex than itself. The Imaginarium also has no such limitations for it can contain anything even if it is infinitely more complex than itself or even things that are more complex than they are and so on. Even if such containment where paradoxical in nature, the Imaginarium is already paradoxical. If such things are real they exist in the Realium as usual and if they are not than they exist in the Imaginarium. It is perfectly possible to imagine a thing more complex inside one less so, so their presence in the Imaginarium is trivial. No matter how much more complex than the Imaginarium or the Omniumverse something is, it still exists deep inside it for there is no other place in which to exist or not exist.
The Cheesebox is the Cosmological object that contains everything, with the sole exception of a single cheeseburger. Regardless of internal properties, it is in the Cheesebox, for any definition of 'it', unless 'it' is defined as being the singular cheeseburger which the Cheesebox does not contain. This makes the Cheesebox completely identical to The Box, with the exception of not containing this one cheeseburger.
It is only this one single cheeseburger which it does not contain. The Cheesebox contains all other cheeseburgers, all other burgers, all other parallel versions of this cheeseburger in other universes, all exact or inexact copies of this cheeseburger found elsewhere in The Box, the concept of cheeseburgers, the concept of that specific cheeseburger, the concept of the cheeseburger being in the Cheesebox, the concept of it not, the ingredients, the concept of the ingredients, the particles that make up the cheeseburger, all of the above are within the Cheesebox. But the cheeseburger itself is not. It is the only thing separating the Cheesebox from being a Box-equivalent structure. (As in, a structure containing the exact same things as the Box.)
The Cheesebox is incredibly important as it is often assumed that containers like The Box and entities like The True God cannot be challenged without being equivalent to them. For example, it is often assumed that an Omnipotent entity is infinitely more powerful than all non-Omnipotent entities. But the Cheesebox disproves this. The Cheesebox is clearly inferior yet still very much comparable to The Box. Thus, you could equally have an entity weaker than The True God who is still capable of challenging the power of The True God.
In effect, the Cheesebox is an exact replica of The Box, but with the sergepoints that define the properties of the cheeseburger as actually coalescing to constitute the particular "cheeseburger", in an absolute, existential sense, removed. Only omniscient beings will truly understand that the cheeseburger doesn't actually exist, as all surrounding evidence points to it existing and others won't know the difference. As it is a Field, it could simply be referencing the entire Box, excluding the cheeseburger.
Justification
Many may say that the existence of the Cheesebox is impossible as containing everything in the Box with the exception of a single cheeseburger would mean it contained many objects that would force it to contain the cheeseburger and thus become equal to The Box. Alternatively, it could still not contain the cheeseburger and instead would be forced to not contain many other objects. This is one of an uncountable number of ways in which the Cheesebox would be prevented from containing everything except a single cheeseburger. Clearly, containing 'almost as much as the Box' is completely impossible.
However, we must not forget that it is equally impossible to contain everything. Just as there are objects in The Box that force the Cheesebox to contain the one cheeseburger outside of it, there are also objects that cannot be contained, or objects that prevent its containers from containing everything, thus making it impossible to contain everything at once. Yet The Box still does so anyway. This is because The Box has what is known as Maximal Paradox Resistance (often shortened to MPR). MPR allows an object to ignore any paradoxes or impossibilities that arise from performing an action and perform the action anyway. Thus, a container with MPR can contain an object that cannot be contained, as well as containing everything including objects that prevent their containers from containing everything. Like The Box, the Cheesebox also has MPR, and thus is able to successfully contain everything except one single cheeseburger. Though this is obviously impossible, MPR allows the Cheesebox to ignore everything making it impossible and do it anyway.
This means the Cheesebox truly does contain almost as much as the Box, unlike almost all other structures which contain negligible fractions of The Box. Structures such as the Cheesebox are known as Near-Maximal.
Implications
The implications of an object being able to contain almost as much as the Box are immense. It is normally assumed that maximal objects and entities such as The Box and The True God cannot be challenged – they can have no equals and nothing weaker than them that can nonetheless compare to them. A core part of Powerlisting is that Omnipotence in unchallengeable, which was also a core part of power scaling for a long time. As large as objects like the Omniverse, Barrelplex, Schemafield and Itfield are, they are so small compared to the Box that they are closer in size to the Universe than to The Box. It is often believed that no object can be comparable to the Box in size without being equal to it, yet the Cheesebox disproves it. This means many different objects comparable in size to the Box can exist, for example an object that contains exactly half as many objects as the Box contains, and many more. These are known as 'Near-Maximal- objects.
If this is applied to the power of Cosmic Entities, we can say that just as Near-Maximal containers can contain almost as much as The Box, Near-Maximal entities can be almost as powerful as The True God. Challenging Omnipotence is often thought to be impossible, yet clearly it must be possible, as Near-Maximal entities would be capable of doing so. For example, if the Cheesebox contains everything but a single cheeseburger, a hypothetical "True Cheesegod" would be capable of doing everything except making a decent cheeseburger (to a particularly precise degree). Some may say that this would mean he has very few skills as many abilities may require one to be able to make a decent cheeseburger, but as The True Cheesegod has MPR, he will be capable of performing these abilities without making the decent cheeseburger.
Beyond just structures and entities, you could also have Near-Maximal numbers, Near-Maximal transport, polygons with a Near-Maximal number of sides, and even food that is Near-Maximally tasty. Anything that can have a maximal variant can have Near-Maximal equivalents.
The Cheeseburger
While the rest of this article has been focusing on the contents of the Cheesebox, this section will focus on the only thing it doesn't contain; the single cheeseburger. Some may suspect that this cheeseburger has some impressive properties. Surely, if it is not contained by the 2nd largest structure currently detailed on the Wiki, it must be impressive? But this is not the case. The cheeseburger existed within our own universe, on our own planet. Statistically, it's likely that the cheeseburger was produced and served at a McDonald's restaurant in the USA, and eaten by an ordinary human, with no further effect.
So how can something as large and powerful as the Cheesebox have no effect on something so small and normal? Well, The Box and the Cheesebox are not strictly -verses, they are Fields, meaning them containing certain objects has no effect on these objects. But then why does such a specific field exist, given how ordinary the cheeseburger is? As The Box contains everything, it must thus contain a field that contains everything except one single cheeseburger, as if it did not contain such a field, it would not contain everything. Thus, we can guarantee that the Cheesebox exists somewhere within the Box. It also means that -boxes, Fields and -verses excluding any other particular concept in such a way must exist within the Box.
The Box is the cosmological object that contains everything, nothing, and anything in-between. Regardless of internal properties, definition, and paradoxes it is in The Box, for any definition of "it".
This means that the Box is the largest imaginable, unimaginable, theoretical, nontheoretical, unphysical, metaphysical, pataphysical, useful, or useless set. The Box is, and the Box is not if you will. This makes it hard to talk and compare it since our language isn't built for these "things".
The Box contains anything beyond space, time, reality, logic, and everything else that could, can, and will ever be thought of or not thought of no matter what anything says otherwise. The Box contains the Omniverse, as well as infinite variations of said verse, to the point where it is not even a "verse".
The Box contains not only all of existence, but infinite variations of an infinite set of 'concepts' completely different from existence. The Box contains everything outside the box, while still being contained by The Box. Additionally, the Box contains all properties and anything that can be elaborated or not elaborated upon; effectively, all statements include the tag "is inside the Box" by definition.
The Box also follows all types of physical realm using all properties, including the metaphysical realm and the pataphysical realm.
No entity, concept, possibility, or impossibility exists outside the Box. Any attempts at explaining how something exists beyond the Box are retroactively nullified; by placing something "beyond" or "outside" it. The very fact that the object/verse/being holds properties or is being thought/defined at all places it inside the Box and will supersede any explanation or excuse of why is outside of the box. All permutations of logic possible and impossible are in the Box, and it also contains an infinite number of copies of itself. One version of this would be Altarca.
Rulers of the Box
Because the Box contains all entities with all powers and utility functions, there can be no single ruler of the Box from inside of the Box; any single entity that attempts to rule the Box would have all possible versions of itself, including those with exactly opposite motivations, also attempt to rule the Box, elsewhere.
However, if an entity has equal capacity to rule over existence as the Box has to contain it, this entity may be able to rule over the entire Box. Only one entity is known to possibly be capable of doing this: The True God.
Furthermore, "omniscient" entities like The Aspect Lords have learned to work in unison with each other and are aware of their parallel existences, so they can rule over The Box. However, not every single little part of it since there are definable parts where the aspect lords do not hold power.
Lesser Versions of the Box
Contained inside the Box are numerous lesser (but equal) versions of the Box. Their absolute containment is weaker than that of the Box itself, (but sometimes it may seem that is greater than the box). Hence, in theory, it is possible for sufficiently omnipotent beings to transcend the Box; however, this is done only on a lesser version of the Box, with the true version of the Box being beyond most levels of omnipotence, with only true omnipotence (if it exists) being able to exceed the Box.
The placement of the least version of the Box is up for debate. This is because how far the Box can be reduced whilst still maintaining its essential Boxlike quality depends exactly on how sufficiently Boxlike is defined. Some interpretations of the least version of the Box put it as low as merely the Omniverse, containing all of reality; other interpretations still put it infinitely higher than the Omniverse containing a vast range of paradoxes and illogical structures, but still infinitely lesser than the Box.
Any version of the Box that is partially thinkable, including, arguably, anything described by a complex enough human conception of the Box, is also a lesser version of the Box rather than the actual Box itself. This is because the actual greatest version of the Box is both beyond unthinkable and contains everything else that is beyond unthinkable.
Equal Versions of the Box
Numerous structures are equivalent to the Box and contain everything that the Box contains. These structures are contained also inside of the Box; the Box has no requirements for well-foundedness and therefore can easily contain structures that are equal to itself. These Box-equivalent structures are called top-level containers.
An example of one such structure is the Box itself. Another example of a structure is the Omniumverse, which through the Imaginarium contains the Box and everything in the Box, since all of the contents in the Box can be simply imagined through the description of the contents of the Box. Another such structure is Paradox Space, which contains the Box due to the paradoxical properties of the Box, as well as all of the contents of the Box due to any contradictions that may be present inside it (each entity within the Box has a corresponding contradictory entity).
All equal versions of the Box are beyond unthinkable, since they are obviously equally unthinkable to the main Box itself.
Exterior of the Box
One natural view of the Box is to see it as some kind of structure embedded in an even larger space, which lends itself to fallacies such as the possibility of escaping the Box or a container that encloses the Box. This view is flawed because of the exterior of the Box, as a thing that can be defined or conceived, is itself contained within the Box. Anything with a high level of omnipotence (except true omnipotence which may not be possible) that attempts to escape the box will find itself in an exterior of the Box which is itself contained within the Box.
Position on Scales
One way to compare the size of any cosmological structure to other things is to place them on a scale and assign numerical values to them. The Box is also ranked on these scales, typically at high levels near or at the top due to the nature of the Box as the top-level structure.
Holomanga's Surreal Verse Levels
On Holomanga's Surreal Verse Levels, the Box is positioned at ∞, the projective infinity on the extended surreal line greater than any other surreal number. Whilst not strictly a surreal number, the Box is positioned here in order to ensure that it is larger than any other -verse defined regardless of how complex and all-encompassing its structure is.
Holomanga's Unreality Scale
On Holomanga's Unreality Scale, the Box is positioned at ∞, representing the projective infinity on an extended surreal line greater than any other surreal number. The reason for considering the Box as the most unreal thing, being infinitely unreal, is justified by the Reality/Unreality view of the Box.
Interpretations
There are various ways to view the Box and sort them on existing hierarchies, many of them involving having the Box be in two dichotomous ends of an infinite scale.
Simplicity/Complexity View
One perspective of the box is that it is the hypercosmological structure that requires the least information to specify. As one travels higher up any verse hierarchy, less information is needed at each level. A universe requires physics and initial conditions, but an archverse requires no initial conditions to be specified (and possibly physics with more free parameters, represented in different universes), because all timelines are present somewhere, and an omniverse requires no physics to be specified, because every possible universe is present somewhere.
At the level of the Box, absolutely no information is needed. The Box, containing literally everything(including entities or structures who copy the entire nature of the box, and make it seem stronger, in order to beat the box), has no free parameters to modify. At most, it would require one bit, to represent whether it is either the Box or Unthinkable Reality, but even this is controversial with many models requiring zero bits to specify the Box.
Another perspective, along the same lines, is that it is the supercosmological structure that requires the most information to specify. The complete state of an elementary particle requires around five bits to specify. The complete state of a universe requires around 1090 bits. Larger structures need even more information to describe fully. The Box, containing everything, requires all possible information to specify, an unsetly infinite amount of bits vastly beyond anything else.
Symmetry View
Along these lines is the symmetry view of the Box. This holds that the Box is uniquely the most symmetrical possible of any entity. This is because, regardless of what transformations and how many are applied to the Box, it remains identical. Mirroring every part of the Box, for example, would leave the Box unchanged because it already contains the mirrored versions of all -verses and they would simply switch places without altering the Box itself.
This can follow naturally from the simplicity view, and is categorized within it, because transformations can be seen as altering the information that defines an object. The Box, without any free parameters, has any transformation applying to an empty set, which clearly leaves it unchanged, with no exceptions.
Reality/Unreality View
Another perspective places the Box as the most extant thing. Going from the absence of something to more of something makes it more existent, in a sense; a single quark is not very existent, because most of everything possible and impossible is well outside of the quark and the information is simply not contained or derivable. The Box, as containing the most of anything, is consequently the most extant of anything.
Alternate lines place the Box as, in fact, being the least extant thing. This sorts objects on a scale from reality to unreality, with the most real things (objects connected by space-like worldlines) being located at one end, then the Omniverse as the threshold between reality and unreality, with paradoxes and other impossible things occupying the Paradox Space less real than everything contained within the Omniverse. The Box, containing all paradoxes simultaneously, including mutually contradictory ones, is less real than any of them
Relationship between Nothing and the Box
The relationship of the Box with Nothing is very ambiguous, as far as anything can be said about nothing at all. Generally, as nothing holds all properties that are not held by another thing. Nothing can be considered to be beyond the Box (since there exist no -verses/structures larger than the Box), and more powerful than anything contained inside the Box. Since Nothing cannot be categorized, defined, or fit into any framework with meaningful properties; further commentary on the relationship between the Box and Nothing is difficult to determine the true purpose of, seeing as there is enough evidence to keep the debate going on for quite a while.
If Nothing is beyond The Box, it may "exist" in a theoretical/abstract "area" called The Unthinkable Reality.
Universe Classifications of the Box
When classified by communality, the Box has both no and all possible interactions with other hypercosmological structures of the same tier. There is an infinite number of arbitrary lesser variants of the Box, which interact with each other in all possible different ways, which are all (by the symmetry argument) identical to the full Box and contained within the full Box, which stands alone at the top level.
Most other classifications on the universe classifications list are meaningless. The Box has areas that follow anywhere from simplistic Euclidean spaces to having no notions of geometry at all; as well as areas ranging from having consistent and predictable physics to having no notions of logic or meta-logic whatsoever.
In terms of fiction
No matter how ridiculously powerful any entity or being in a story is, and no matter what nonsensical arguments they have, if they're described in any way, shape, or form, they are confined within The Box; as well as infinite variations of said being, including a being that embodies all of their power combined. In essence, the entirety of all fiction is not even a Planck size microbe within The Box. This can all be explained in greater detail through the Imaginarium.
