Naturalness Without Fine-Tuning: Structural Admissibility and Einstein's Question Revisited

The naturalness problem in modern physics arises from the apparent fine-tuning of low-energy parameters—most notably the Higgs mass and the cosmological constant—relative to expectations from high-energy quantum field theories. These discrepancies are often framed as requiring either coordinated cancellations between ultraviolet (UV) contributions or anthropic selection within a multiverse. In this paper, we argue that the naturalness problem is a category error rooted in force-first, reductionist ordering. When physical description is reordered such that geometric and structural admissibility precede dynamical force contributions, the apparent fine-tuning dissolves. Small infrared (IR) parameters are reinterpreted as survival signatures of persistent structures rather than improbable outcomes of blind microscopic processes. This framework provides a non-anthropic resolution of naturalness and yields a concrete answer to Albert Einstein’s question of whether the universe could have been otherwise: persistence collapses the space of viable worlds, rendering the observed structure inevitable without invoking multiverse sampling or UV–IR collusion.
