Retrocausality, or inverse causation, refers to a model of non-linear causality in which the effect may precede the cause or influence the conditions of its own past. Used in quantum physics and philosophy, it challenges chronological linearity by suggesting that the future can exert an influence on the present. The chain of causes and effects ceases to be an ordered sequence and becomes a symmetric feedback loop, where time loses its hierarchy. From this perspective, retrocausality converges with symplanicity in an acausal and atemporal logic, where the relation between phenomena unfolds not in the succession of time, but in the coincidence of planes or of meaning.
