Five Testable Predictions of the Infinite-Dimensional Multiverse Model (IDM)

The Infinite-Dimensional Multiverse Model (IDM) postulates an infinite number of spatial dimensions and infinite nesting of neighbouring universes. Within the IDM, the fundamental constants of physics are not random or fixed, but represent evolutionary attractors – equilibrium states toward which the system is drawn under the action of an infinite number of weak interactions with neighbouring universes. The model offers five specific, falsifiable predictions that distinguish it from the standard ΛCDM model. First: fundamental constants are not independent but form a low-dimensional manifold (attractor). Second: ultra-weak spacetime variations of constants should exist at the level x/x 10^-6–10^-5, correlated with the large-scale structure. Third: the cosmic microwave background (CMB) power spectrum should contain statistically significant anomalies at multipoles l = 2, 3, 4. Fourth: compact regions with anomalous values of constants should exist in the large-scale structure. Fifth: the cosmological constant is not strictly constant but slowly evolves in time ( (t) 1/t²). For each prediction, the verification method, the threshold at which the prediction would be considered not confirmed, and the expected data timeline (2026–2040) are specified. The thresholds are not derived from first principles of the IDM but are based on the actual experimental capabilities of telescopes (JWST, ELT, SKA, Planck, DESI). If, after reaching these thresholds, the predictions are not confirmed, the IDM is either false or requires substantial revision (e. g. , lowering the predicted range of variations). The model loses its status as an empirically supported alternative and returns to the realm of speculative hypotheses.
