11D Physics

The study of physical laws across eleven dimensions, the maximum framework required by M-theory, which unifies all string theories into a single 11D structure. In 11D physics, the universe is understood as a vast, multidimensional landscape where different regions have different dimensional geometries, different physical laws, different realities entirely. 11D physics investigates the ultimate nature of existence—how dimensions relate, how membranes interact, how the entire cosmic manifold fits together. This is the physics of everything, everywhere, all at once—the most comprehensive, most ambitious, most unprovable framework ever conceived. 11D physics explains everything and predicts nothing, which is either its glory or its fatal flaw, depending on whether you value testability or beauty.

Example: "She tried to explain 11D physics to her mother, who asked what practical use it had. 'It unifies all forces,' she said. 'It explains the fundamental nature of reality. It's the theory of everything.' Her mother asked if it would help find the car keys. She said no, but in some 11D branches, they were never lost. Her mother found them in her purse. 11D physics had failed again, but at least it was beautiful."

Multiverse Physics

The overarching discipline that studies the physics of the multiverse—the laws, forces, and phenomena that govern not just one universe but the entire multiversal landscape. Multiverse physics asks questions like: What determines the laws of individual universes? How do universes interact, if at all? What is the origin of the multiverse itself? This physics is highly speculative, drawing on string theory, quantum gravity, and cosmology, but it's also the most ambitious intellectual enterprise ever attempted—nothing less than the explanation of all reality, everywhere, in all forms. Multiverse physics is either the ultimate science or the ultimate fantasy, depending on your tolerance for untestable theories.

Example: "She studied multiverse physics and could now explain why our universe has the laws it does: it's just one random outcome in an infinite multiversal landscape, no more special than any other. The explanation was either profound (we're not special) or trivial (things are the way they are because they could be otherwise). She wasn't sure which, but she had a PhD."
