A megaverse is a collection of many multiverses and the infinite links and dimensions between them. It's an infinite set of simultaneous multiverses that contain an infinite amount of instances and all laws of physics. By this definition, there cannot be time travel paradoxes or causality violations.
It is sometimes called the quantaverse because it can only be accessible after the discovery of 6d, the quantum dimension.
Many-Worlds Interpretation[]
The Many-Worlds Interpretation (MWI) states that all possible outcomes of quantum measurements exist in separate “worlds” or universes. This interpretation views time as a many-branched tree, where every quantum outcome is realized in its own universe, aiming to resolve paradoxes like Schrödinger’s cat. MWI is deterministic and local, and it implies the existence of infinitely many universes.
Ninth dimension[]
9d physics is the result of collateral force which is another version of fate as the decisions of others steers the whole. This totality of the multiverse means that fate cannot destroy time or merely bury the mass in a resultant redistribution against a causality paradox.
