Validation & Falsifiability

Two different things get called “validation” casually, and this site keeps them separate on purpose: passing an internal simulation check means the theory’s own equations behave the way the theory’s own text says they should. Passing an observational check means the theory matches independently collected real-world data. Right now this corpus has real, verified 16/17 internal checks — and one honest gap (SPARC) where the observational data simply isn’t available yet.
