A speculative field studying the physics of outer spacetime regions—universes beyond our own, dimensions beyond the four we know, realms where different physical laws apply. Outer Physics asks: if there are other spacetimes, what physics operates there? It's physics extended to the multiverse, physics as a local phenomenon rather than universal law. The field is necessarily speculative—we can't observe outer regions—but it's a necessary thought experiment for understanding whether our physics is unique or just local.
"Our physics works here—but what about there? Outer Physics studies the physics of other spacetimes, other dimensions, other realities. Not science fiction, but necessary speculation: if the multiverse exists, it has physics. Outer Physics is the attempt to imagine what that physics might be."
