Dimension

A dimension is a coordinate in space. Thus, an n-dimensional object is one that needs at minimum n coordinates to specify a point anywhere in it. A dimension is the term used in the formal science to define a cosmological ontology. Dimensional can also be use in philosophy to purely abstract about ontological being.

A realm has an infinite amount of dimensions. Anything inaccessible through the concepts of dimensions is "other-realmly".

A brane is a physical object that generalizes the notion of a point particle to higher dimensions. For instance, a point particle can be viewed as a brane of dimension zero, while a string can be viewed as a brane of dimension one. It is also possible to consider higher-dimensional p-branes. The word comes from "membrane" which refers to a 2d brane.

Pocket Dimensions (subspace child matrices) are small extra pockets of space that are attached to our own. Much like an actual pocket, they are often used for some extra space where you can get things bigger on the inside. Examples are the Bag of Holding and the TARDIS.

It should be noted here how the megaverse can have infinite dimensions, and yet the omniverse can include the megaverse, and the hyperverse can include the omniverse. Well, there are different sizes of infinity according to set theory. Set theory of transfinite numbers, absolute numbers and the continuum hypothesis talk about higher infinities, or sets that have larger infinities than their subsets. This relates to the number of dimensions in each verse.

The universe goes up to 4d, the multiverse 6d, the megaverse 7d to 11d (which is the first subset of infinity), the omniverse 11d (which has a higher infinity but includes the subset of the megaverse), and then the hyperverse which is greater than 11d up to an infinity of dimensions, of which the omniverse is a subset.
