# PhysEvolve: Verifier-grounded Self-evolution for Physical Reasoning with Executable Worlds > Source: > Published: 2026-10-28 04:31:14+00:00 Physical reasoning underpins how embodied systems understand and act in the physical world, yet vision-language models (VLMs) remain unreliable on questions about dynamics and physical causality. Progress is critically constrained by the scarcity of grounded counterfactual training data, as observat
