There absolutely is. The speed of light is the speed of causality. It is very tightly integrated into the framework of modern physics.
Maybe you are confusing causality for the arrow of time?
- layer8 1y agoModern physics says little about causality. The fundamental laws are all field equations. Those set constraints about how the physical state of a system can evolve between two points in time, but there is no notion of causation, only of consistency or (im)possibility. Causation in physics is a complex and problematic notion: https://plato.stanford.edu/entries/causation-physics/ https://plato.stanford.edu/entries/causation-physics/
- adastra22 1y agoI think we are talking past each other. Defining how the system evolves is defining how initial conditions must lead to (cause) intermediate and final states. That’s causality in the logical sense. What I’m talking about is most similar to the “Causal Explanation” section at the end of the article you link.
