The Semantics of the Universe Itself: Towards a Computational Perception of the Unfolding of Events

The Standard Model of particle physics—our best, current under- standing of the universe—is normally specified as a Lagrangian density, evaluated via the machinery of quantum field theory. We propose to recast it in the language of structural operational seman- tics (SOS)—the formalism that underpins programming language theory and process calculi. In this view, particles are processes, in- teraction vertices become inference rules, and amplitudes decoratetransitions. Probabilities emerge by applying the Born rule to deriva- tions. This reformulation does not alter physics, but it rephrases the Standard Model as a probabilistic process calculus, making it amenable to the full toolbox of computer science semantics. We sketch preliminary SOS rules for QED (Quantum Electrodynamics) and issue an open invitation: if the events of the universe unfold as computation, then the Standard Model is essentially its programming language: The Universal Calculus and computer scientists are, in fact, (already) uniquely equipped to reason about it through half a century of experience with all kinds of (abstract) computational models.
