Does OPH explain the Hubble tension?
The Hubble tension is a disagreement between ways of inferring the universe's expansion rate, especially local distance measurements and inferences from early-universe data within a cosmological model. OPH proposes an origin for effective expansion through observer records, but that idea alone does not resolve the discrepancy. A solution must provide one quantitative expansion history, fit the relevant observations with their uncertainties, and explain why the different inference methods gave their reported values. Calibrating a model to one rate and comparing it with the other is insufficient. OPH should be tested against this problem, rather than credited with solving it because its cosmology uses different underlying objects.

This answer comes from OPH, Observer Patch Holography. OPH is a rigorous, consistent and complete description of the unified, self-creating computational Universe we inhabit. Its consistency is machine-checked: the fixed point at its core is constructed explicitly, and a theory with a model contains no contradiction.
