Universes Here: Many-Worlds as a Change of the Level of Description G

The article proposes a new interpretation of parallel universes: they are not located "somewhere far away," but exist in the very same volume of space as our Universe. Different universes are different sets of active elements of reality that we "read" from a single "set" at different levels of description G. The key metaphor is the airport board: the board is one and the same, but by opening different cells we get different symbols. Formally: Universe U(G) = P(G)(Ω), where P(G) is the projection operator, Ω is the complete set of all degrees of freedom. The transition between universes is a change of the level of description G, not movement in space. This distinguishes the model from Everett's many-worlds interpretation, where branching is irreversible: in the proposed model the transition is reversible. A comparison is conducted with existing interpretations: Everett's MWI, Tegmark's Multiverse, MIW of Hall, Wiseman, and Deckert, brane worlds in string theory. It is shown that the model occupies a unique niche: not branching, not interaction, not remoteness, but an ontological choice. Consequences for superluminal communication are discussed: the signal does not fly through a brane but switches to another G. Verifiable consequences are proposed: anomalies in the cosmic microwave background, vacuum fluctuations, indirect markers. The model is consistent with the principles of the projection ontology of EFOS and resolves the problems of the standard many-worlds interpretation: it does not require infinite energy, does not require postulating irreversible branching. Key conclusions: parallel universes are here, in one volume; the transition between them is a change of G; the model has verifiable consequences.
