The Many Worlds Interpretation Has Exhausted Its Chips

The blog post argues that the Many Worlds Interpretation (MWI) of quantum mechanics suffers a fundamental flaw: its branch‑counting probability measure μ is undefined without a preferred basis, making empirical predictions impossible. It likens this structural deficiency to the Rayleigh‑Jeans ultraviolet catastrophe, where a missing binding condition caused a divergence. The author contends that self‑locating uncertainty merely relocates the measurement problem rather than solving it, and that an external ontological condition—dubbed the n+1 planar primary—is required. Consequently, the MWI has exhausted its explanatory power and needs a new foundational premise.
