4D Sciences

The systematic study of phenomena across the four dimensions of spacetime—length, width, height, and time. Unlike 3D sciences, which treat time as a separate parameter, 4D sciences integrate time as a full dimension, meaning objects are understood as four-dimensional "worldlines" extending from birth to death. A person isn't a 3D object that changes over time; they're a 4D object—a spacetime worm—with their infant self connected to their adult self connected to their future corpse. 4D sciences explain why you can never step in the same river twice (the river's 4D shape is different), why your past self feels like a stranger (they're just far away in the time dimension), and why you should be nice to your future self (they're literally the same 4D object).

*Example: "She applied 4D sciences to her relationship, viewing it as a single four-dimensional object rather than a series of 3D moments. The fights weren't separate events; they were just points on the relationship's worldline. The good times were other points. The whole thing was one continuous shape. It didn't make the fights hurt less, but it helped her see them as part of something larger."*
