Physicists are now writing the laws of the universe as computer code to prove that certain 'theories of everything' are mathematically perfect.

Physics as Code: From Scans to Theorems with ITP APIs in $SU(5)$ Model Building
arXiv · 2603.28406
The Takeaway
Instead of just calculating equations, researchers are using professional logic-verification software to build 'bug-free' models of high-energy physics. This approach turns the search for new particles into a rigorous computer program that can prove with 100% certainty which theories are actually possible.
From the abstract
A recurring challenge in theoretical physics is to make reliable global statements about bounded but combinatorially large model spaces. Exhaustive scans quickly become opaque or impractical, while statistical exploration does not by itself provide theorem-backed guarantees. This motivates workflows in which the model-building problem itself is formalized inside an interactive theorem prover (ITP).In this paper we develop an API-based methodology for formalizing such bounded model-building quest
