A profound paradigm shift is occurring in theoretical physics: the transition from a mechanistic view of reality (forces acting locally over time) to a constraint-based and information-theoretic view. This unified framework is supported by several interconnected concepts across fundamental physics:

• Action Principles and Symmetries: Instead of calculating localized "pushes and pulls" (like Newton's laws), modern physics relies heavily on action principles (Lagrangian mechanics), which determine a system's path by looking globally at energy tradeoffs between starting and ending points. Coupled with Noether’s Theorem, this reveals that conservation laws (like energy and momentum) are not arbitrary forces, but necessary mathematical consequences of a system's continuous symmetries.
• Quantum Constraints: The Pau ...
