The study of shapes and spaces in seven dimensions, where the seventh dimension is often considered the space of all possible physical laws—every possible set of constants, forces, and rules that could govern a universe. In 7D geometry, objects have seven perpendicular axes, allowing for forms that contain all possible universes with all possible physics. A 7D object would transcend not just our history but our very conception of reality. 7D geometry is what physicists invoke when they talk about the multiverse of string theory, where different "branes" (membranes) exist in higher-dimensional space, each with its own physical laws. It's the geometry of "what if gravity were stronger?" and "what if the speed of light were slower?" and "what if math itself were different?"
Example: "She invoked 7D geometry to explain why her diet wasn't working. 'In this universe, with these physical laws, calories matter. But in a 7D branch with different physics, maybe I could eat anything and stay thin. I'm just in the wrong dimensional slice.' Her trainer said to stick to the 3D reality where exercise also matters. She sighed, accepting that some dimensions are more inconvenient than others."
