Understanding Causal Invariance

Causal invariance is a foundational concept in Wolfram physics that plays a critical role in deriving both special relativity and quantum mechanics from the Rolfram model. It refers to how different branches within a multi-way graph can return to a common point, indicating that various paths through the universe may lead to similar outcomes. This concept challenges traditional views in physics, especially in the context of the Many Worlds interpretation of quantum mechanics, where universes branch off without interacting. The ability of branches to come together introduces a framework where multiple realities could eventually collapse into a single, objective reality.
