A dimension is a coordinate in reality. Thus, an n-dimensional object is one that needs at minimum n coordinates to specify a point of existence anywhere in it.
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. The word "brane" comes from "membrane" which refers to a 2d brane. Branes such as a tesseract are used to conceptualize higher-level dimensional structures.
Becaused the graviton (the quantum of gravity) is the lightest particle known, at 1.07×10^{−67} kg, higher dimensions are rolled up into tiny, compactified loops. They are therefore undetectable until the science exists to view them.
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.
Reality has infinite dimensions. Anything outside reality is unbound by dimensions and is sometimes referred to as "other-realmly". This wiki prefers to have all of existence defined by realms of different levels.

n | Dimension |
---|---|
{} | Empty set, or nothingness, or oblivion. Universes may arise from nothing. A black hole can regress into nothing. An outerverse particle is undefined and, at most, nothing. |
0 | Point {e} (a location in reality or an element in a set). A singularity is 0d. |
1 | Line (a collection of points along an axis). Cosmic strings are 1d. |
2 | Plane (height and width with x and y axes). |
3 | Space (height, width and depth with x, y, z axes). |
4 | Spacetime (the addition of Unidirectional Time, the temporal axis t which is analogous to the x, y and z axes) (can result in time dilation with special relativity as an object approaches the speed of light). Understood by 3d beings using a 4d analogous structure such as a tesseract. Traditional boundary of a universe until gravity is understood as a dimensional force. |
5 | Gravity is a strong force that holds a plane of probability together that contains branching timelines (can result in gravitational time dilation with general relativity). An infinitesimally small amount of gravitons leak into lower spacetime dimensions, creating visible evidence that gravity is weak, but is strong in a 5d reality. This was once known as the dark dimension. Inertial force that initiates a Big Bang. |
6 | Multidirectional Time, a plane bound by the four fundamental forces, allowing us to access all futures, presents, and pasts (within one instance). This was made possible by the quantum-gravitational Theory of Everything. This is the boundary of the multiverse and traditional spacetime with old laws of physics. |
7 | Quantum dimension with new fundamental forces, and new laws of physics. |
8 | All Possible Timelines where there is an infinite number of instances accessible via the quantum dimension. This makes a megaverse possible. |
9 | Subspace u-axis, with old and new laws of physics |
10 | Subspace v-axis, with old and new laws of physics |
11 | Subspace w-axis, with old and new laws of physics. This is the boundary of the current omniverse. 11 is the upper bound of M-theory. |
12+ | Unstable and paradoxical within the current omniverse, and particles naturally collapse back down into 11 dimensions. |
12...26 | Multidimensions of the hyperverse. 26 is the upper bound of string theory. |
>26 | Megadimensions of the hyperverse. |
∞ | Omnidimensions of the hyperverse. |
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.
