THE 1.5 HYPOTHESIS: A Unified Geometric Framework for the Hubble Tension and Neutrino Mass Anomalies via Spectral Fractality

Abstract

La cosmología de precisión ha entrado en una fase de tensión crítica. Las discrepancias observacionales entre el Universo Temprano ($z \sim 1100$) y el Universo Tardío ($z < 2$) sugieren una ruptura del modelo de concordancia $\Lambda$CDM. En particular, la Tensión de Hubble ($5\sigma$) y la reciente preferencia por masas de neutrinos negativas en los datos de DESI Y1 apuntan a una incomprensión fundamental de la energía oscura y la geometría del vacío. En este trabajo, proponemos que estas anomalías no requieren nuevos campos cuánticos, sino una revisión de la topología del espaciotiempo en el régimen ultravioleta (UV). Postulamos una dimensión espectral fractal $d_s \approx 1.5$ a la escala de Planck, asociada a la fase de bifurcación en Triangulaciones Dinámicas Causales (CDT). Demostramos fenomenológicamente que esta dimensionalidad induce: (1) Una entropía de horizonte super-extensiva (clase Barrow $\Delta \to 1$) que genera una energía oscura fantasma efectiva ($w \approx -1.5$), resolviendo la tensión de Hubble; y (2) Una masa efectiva para los neutrinos mediante una resonancia geométrica análoga a la Anomalía de Kohn. Utilizando argumentos de ruptura de simetría en grupos excepcionales ($E_6$), derivamos un límite inferior de masa $\sum m_\nu \gtrsim 0.06$ eV, restaurando la consistencia física ante los datos de DESI.
