This article is about the physical definition of "causality". For causality in general, see Causality.
For other uses of "Causation", see Causation (disambiguation).
Physical causality is a physical relationship between causes and effects.[1][2] It is considered to be fundamental to all natural sciences and behavioural sciences, especially physics. Causality is also a topic studied from the perspectives of philosophy, statistics and logic. Causality means that an effect can not occur from a cause that is not in the back (past) light cone of that event. Similarly, a cause can not have an effect outside its front (future) light cone.
