The branch of physics describing how objects move and interact across the multiverse—how they navigate between universes, how they maintain identity across branches, how they respond to the multiversal landscape. In multiverse mechanics, motion is not just through space and time but through the space of possible universes. Objects can have trajectories that take them through different realities, different physical laws, different dimensions. This mechanics is purely theoretical—we have no evidence of actual inter-universe travel—but it's mathematically coherent and conceptually thrilling. Multiverse mechanics is the physics of "what if we could move between realities?"—a question that has haunted dreamers forever.
