Invariant Set Theory: Violating Measurement Independence without Fine Tuning, Conspiracy, Constraints on Free Will or Retrocausality

TL;DR

Invariant Set Theory proposes a deterministic, fractal-based model of the universe that explains quantum phenomena without fine tuning or conspiracy, suggesting a new approach to unifying gravity and quantum physics.

Contribution

The paper introduces a novel invariant set framework that violates Bell inequalities without fine tuning or conspiracy, linking cosmology with quantum and gravitational physics.

Findings

Violates Bell inequalities via Measurement Independence violation

Invariant set has Cantor set structure and zero measure in Euclidean space

Quantum theory emerges as a limit of IS theory when p approaches infinity

Abstract

Invariant Set (IS) theory is a locally causal ontic theory of physics based on the Cosmological Invariant Set postulate that the universe $U$ can be considered a deterministic dynamical system evolving precisely on a (suitably constructed) fractal dynamically invariant set in $U$'s state space. IS theory violates the Bell inequalities by violating Measurement Independence. Despite this, IS theory is not fine tuned, is not conspiratorial, does not constrain experimenter free will and does not invoke retrocausality. The reasons behind these claims are discussed in this paper. These arise from properties not found in conventional ontic models: the invariant set has zero measure in its Euclidean embedding space, has Cantor Set structure homeomorphic to the p-adic integers ($p \ggg 0$) and is non-computable. In particular, it is shown that the p-adic metric encapulates the physics of the Cosmological Invariant Set postulate, and provides the technical means to demonstrate no fine tuning or conspiracy. Quantum theory can be viewed as the singular limit of IS theory when when $p$ is set equal to infinity. Since it is based around a top-down constraint from cosmology, IS theory suggests that gravitational and quantum physics will be unified by a gravitational theory of the quantum, rather than a quantum theory of gravity. Some implications arising from such a perspective are discussed.
