Multiverse

Multiverses take up their own massive contained areas in megaspace, containing their own predetermined laws of physics and properties.

Formation
Megaspace is constantly bombarded by cosmic storms from the particles that compose reality, which is part of why the environment is extremely difficult to inhabit permanently. If these storms collect and come together in just the right formation, a multiverse can start to form as these particles combine themselves together and form the laws of physics for the young multiverse. These early stages are highly volatile, however, and in many cases either no physics are properly formed or they are formed in a self-destructive fashion. Many multiverses never form properly, either falling apart due to failing to form physics or eventually decaying under the weight of their unsustainable laws.

If a multiverse successfully manages to avoid collapsing and forms cohesive physics, it will slowly start to expand and take shape according to the laws it has created. The multiverse membrane will also start to grow around it, giving them their own These primitive multiverses start to develop their own inhabitants. In this state they still can suffer flaws, but if they do so their growth is more likely to be stunted and half-formed rather than falling into pieces. Eventually, it will grow to a fitting size with a stable membrane and start to settle, which is when advanced societies inside of them can begin to form.

Properties
The mechanics of how multiverses regulate their laws of physics is rather unknown. One theory is that they create their own fields of reality warping in order to regulate the area according to their laws. Since the natural state of megaspace is an unregulated territory with very sparse laws of physics, doing so would be trivial. This also explains why beyond the confines of a multiverse their laws of physics apply on the megaspace on their edges, as the effects of their fields take a bit to diminish outside of their membranes.

Despite the theories of some timelines, multiverses don't infinitely contain all possibilities. They do contain a very large set of possibilities, but this is very different than every single possible thing in the infinite expanse of possibilities. They're more akin to galaxies, in that there's a vast but limited amount of things contained inside of them.

Similar Multiverses
It's a noted phenomena that similar multiverses tend to form within the same neighbourhood. Since the process is on paper random, it's somewhat puzzling why this happens. One piece of speculation is that even outside of notable influence, neighbouring multiverse still have an ever so slight influence on the laws of physics in the area. It's barely visible and often lost by the pull of other multiverses, but it's strong enough to influence new multiverse to be more likely to form some similar laws of physics. Exact copies of another multiverse in this manner haven't been observed, so if this theory is true it isn't absolute.

Another theory states that similar multiverses forming are due to a deviation in the formation processes. When a multiverse is still forming, certain events can cause them to split in half, with some laws of physics determined already. When the split happens, the formation of each separate multiverse gives them different laws deviating from that point, resulting in multiverses with similar properties in some manners.

Dimensions
Although the individuals on the net and from this multiverse use the system of dimensions to measure things, dimensions are not necessarily a vital aspect of multiverses. There are some that have vastly different timeline structures, their own local time, and no timelines whatsoever to name a few. While dimensional measurement works for the purposes of the nets framework, it is not exactly an accurate model in of itself when taking into account how reality functions. Therefore scholars and scientists who originate from outside of this multiverse use a difference system altogether.

Prime Chronoverse
The main multiverse where TTN takes place, it consists of multiple timelines and has some rather understood laws of physics. Sometimes just shortened to Chronoverse.

Nullwhere
A multiverse very similar to the Prime Chronoverse, but still with some notable change. Instead of matter, everything in nullwhere is made up of antimatter. In addition, the timeline structure forms in such a way that timelines themselves and even the entire multiverse can gain their own sentience. Otherwise, its laws of physics are identical to the Chronoverse. It neighbours the downskew.

Due to the fact the entire multiverse birthed an entity called V'ana that wanted to consume the Chronoverse, it was practically nuked through being filled with matter by Alex. While it was initially filled with nothing but energy for a bit, Nullwhere eventually started to recover. It's now at the stage where it's started to create timelines again, mostly being cleared of energy - meaning that a new lifeform of some type might be born from there soon.

Kelthine
Kelthine neighbours Nullwhere on one of its skews, and is characterized mainly by the resonance sentience has with the physical matter of reality. Its timeline stucture is also vastly different, to the point that timelines are non linear and often fold into each other or other timelines. They also have three types of naturally occurring soulforms: Kels, Cores, and Sparks. Not much is really known about it by the travellers of TTN.

 * Space within a multiverse and outside of a timeline are referred to as "hyperspace".
