Perfect Self-Containment and MDL: Why the Universe Has to Select Itself

Why do the laws of physics have the specific values they do? The Standard Model of particle physics is the most precise physical theory ever constructed, but it cannot explain its own parameters — it requires approximately 25 free constants that must be measured and inserted by hand. The UGP Physics framework answers this through two interlocking principles: Perfect Self-Containment (PSC), which requires that the universe's description be internally self-consistent without external reference, and the Minimum Description Length (MDL) criterion, which selects the simplest such self-consistent description. This tutorial explains both principles, their mathematical formulation, and how their combination forces the universe to select the specific polynomial and parameters that match the observed Standard Model.
