Lawhood Criteria for Multiple-Time Retrocausal Models

Ascertain whether the multiple-time, retrocausal Fixed Point Formulation satisfies recently proposed criteria for lawhood in all-at-once retrocausal theories, such as those articulated by Adlam.

Background

The paper advances a deterministic, event-symmetric, all-at-once retrocausal formulation of quantum mechanics and argues that probabilities follow from the structure of the universal wavefunction. Adlam has proposed criteria for understanding laws of nature as constraints in such retrocausal frameworks.

The author explicitly invites examination of whether the Fixed Point Formulation meets these lawhood criteria, thereby testing the framework’s standing as a fundamental, law-governed description.

I am optimistic that the ideas contained in this work can be connected to many open research questions, some of which I sketch here: Can the multiple-time, retrocausal model developed here satisfy new criteria for lawhood () in all-at-once retrocausal theories?
