The Hubble Tension as a Signature of Psychegenesis: A Two-Phase Cosmology Model with Collapse at 555 Million Years Ago

Previous versions of this document contained AI-generated mathematics which contains mistakes I cannot fix. This version contains the philosophical argument I should have been making all along. The Hubble tension—a stark discrepancy between early- and late-universe measurements of the Hubble constant—has emerged as a crisis for the standard ΛCDM model. Efforts to resolve this tension through modified physics or exotic fields implicitly accept the ontological validity of early-universe inferences. We challenge this assumption. In this paper, we develop the framework of Two-Phase Cosmology (2PC), in which reality undergoes a phase transition from a pre-physical quantum superposition to a post-collapse classical universe, triggered by the emergence of conscious observers. We show that 2PC (1) eliminates the need for inflation, (2) dissolves the ontological status of ΛCDM before observation, and (3) reframes early-universe "measurements" as retrospective model fits rather than physical detections. Consequently, the Hubble tension is not a physical problem requiring resolution, but a philosophical confusion to be dissolved. We end by proposing a new observational program rooted in a 2PC-compatible cosmology, reframing cosmological inference as the reconstruction of a stabilized post-collapse reality.
