A Normal pocket Dimension / Reality is a small reality space with extremely varying size and dimensionality, ranging from around a femtometer to a couple million lightyears at the very extremes.
The difference between a Normal and Special pocket dimension is pretty complex, so here is a graph of all the details and differences:
Normal Pocket Dimension | Special Pocket Dimension |
- Has a generally 'Normal' set law of physics - Can be *relatively* easy to artificially create - Very common compared to special pocket dimensions - Limited dimensionality, 0d to 11d is most common, but any positive finite number is still allowed - Very stable in structure, almost never collapses | - Free in terms of bound laws of physics - No known way to create; only found naturally or from a high level god or entity - Very rare, the only places where it is considered 'common' are usually where gods reside - Can have up to infinite dimensionality and even negative dimensions - Highly unstable and chaotic, however still isn't likely to collapse |
There has even been an organisation which's purpose is to allow people access of a pocket dimension, in what is known as the Small Pocket Dimension Complex, containing a grid of Normal pocket dimensions each 1 kilometer wide.
