Phenomenological Evidence for Three Horizon‑Scale Coherent Energy Regions and Cosmic Anisotropy

Observations of the Cosmic Microwave Background (CMB) reveal persistent large‑scale anomalies at low multipoles (ℓ≲30), including the Cold Spot, the quadrupole–octopole alignment (the so‑called “Axis of Evil”), and hemispherical power asymmetry. Independently, late‑time observations indicate coherent bulk flows, large‑scale attractors, dipolar signatures, and a persistent tension in the Hubble constant H₀. We propose a phenomenological interpretation in which these effects arise as the observational imprint of three physically real, horizon‑scale energy regions. These regions generate coherent and persistent gravitational gradients that introduce direction‑dependent gravitational contributions to the observed redshift and induce coherent bulk flows. The resulting anisotropic redshift component produces direction‑dependent variations in H₀ measurements, providing a causal explanation for the Hubble tension. This framework operates entirely within General Relativity, relaxing the assumption of global statistical isotropy and offering a testable phenomenological model for multiple cosmological anomalies.
