A monocosm is an imaginary barrel that contains reality, and stops it getting out of control. Inside the monocosm are monocosmic strings that vibrate and keep it in its stable state. A monocosm can contain anything from 1 to 10100 Omniverses, the Outside and 2 Godverses for each Omniverse.
Our monocosm is The Barrel.
Unstable Monocosm[]
In the event that a monocosm does become unstable, unfortunately there is no way to escape it or stabilise it. (Unless one is a Type 37.0+ civilization). The fragments of reality inside it will break free and wander for countless millenia before finding a new monocosm to reside in. (Or Sometimes monocosm become so unstable that it can collapse and Destroy anything inside of it). Once the realities find a new monocosm and reside there, the laws of physics for each monocosm may change drastically.
Kardashev Civilizations[]
It can be hypothesized that a Type 12.0 Civilization can reside in the entirety of the monocosm and a Type 13.0 Civilization can break free and explore the rest of the Altarca beyond.
Or Maybe Type 37.0 Civilization Will Contruct or maybe change the laws to lower the chance of collapsing itself or broke apart.
