The metaverse is the "internet" equivalent of verses; it is a network of "computers" simulating universes, and is set within a Xenoverse. It contains a huge amount of multiverses, collectively representing a lot unique multiverses under a continuous set of laws each with their own combination of matter, space, energy, time, etc.
Due to the limitations of data, the multiverses within a Metaverse within normally can only get so precise, so as a result, Metaverses do not usually host a infinite amount of multiverses.
Metaverses are also too "artificial" to be natural, so as a result of this, they have their own unique methods of formation, which are typically executed by high level civilizations.
The term of a "Metaverse" was coined in Neal Stephenson's 1992 science fiction novel Snow Crash, where humans, as avatars, interact with each other and software agents, in a 3D space that uses the metaphor of the real world. Stephenson used the term to describe a virtual reality-based successor to the Internet. Concepts similar to the Metaverse have appeared under a variety of names in the cyberpunk genre of fiction as far back as 1981 in the novella True Names. Stephenson stated in the afterword to Snow Crash that after finishing the novel he learned about Habitat, an early MMORPG which resembled the Metaverse.
The structure of a Metaverse somewhat resembles the data structure of a hard drive but on a much larger scale.
The metadata of a Metaverse is located in the central hexagon/heptagon of a Metaverse to minimize "jump distance" of signals.
Every heptagon in a metaverse has randomly arranged hexagons and heptagons in it that are the "files" of the Metaverse. These heptagons themselves have their own "files", and so on. The edges of each heptagon and hexagon in the Metaverse are also allocated for the metadata of said heptagons and hexagons.
Typically, the hexagons and heptagons are made of Electrium, an un-naturally conductive substance. This allows for the ease of transfer of signals with minimal data loss.
