Infinite-Dimensional Multiverse Model (IDM) Extension of the Open Universe Model

An Infinite-Dimensional Multiverse Model (IDM) is proposed as an extension of the previously developed Open Universe Model (OUM-1/190526). While the original OUM postulated a finite number of neighboring universes along one additional w-axis, IDM takes the next logical step: the number of spatial dimensions and levels of multiverse nesting tends toward infinity. The main conclusion of IDM is that the principle of conditionality (determinism) ceases to hold for the complete set of events in the entire multiverse. Some events in our Universe are fundamentally unpredictable — not due to lack of data or computational power, but because their causes lie in infinitely distant regions of reality, inaccessible to any observation. The model ontologizes unpredictability: the absence of access to a cause and the absence of the cause itself are different claims, yet for an observer within our Universe they are indistinguishable. The work analyzes in detail the connection between IDM and the fine-tuning problem of fundamental constants. Instead of an "improbable coincidence" or the anthropic principle, IDM proposes a reformulation: the values of constants may be evolutionary attractors in the space of multiverse constants, toward which the system is drawn under the influence of an infinite number of weak interactions with neighboring universes. The model is a speculative physical hypothesis of the highest level. However, it provides a new framework for understanding the limits of cognition, the nature of randomness, and the boundaries of the principle of conditionality. Physicists, philosophers, and methodologists of science are invited to dialogue and to further develop the model.
