The study of phenomena across five dimensions: spacetime plus probability. In 5D sciences, every event exists not just at a specific spacetime coordinate but across a spectrum of probability branches. The 5D sciences investigate how objects and events are distributed across these branches, how they interact between branches, and why you always seem to end up in the branch where you forgot your keys. 5D sciences explain déjà vu (brief overlap with a probability branch where you've already experienced this), intuition (access to information from branches where you already know), and regret (awareness of branches where you made better choices). It's the science of "what if" made rigorous.
