 There are two key ideas that punctuate the historical development of the notion of retrocausality in quantum mechanics. The first proposal of retroactive influence in quantum mechanics comes from a suggestion made by Wheeler and Feynman (1945, 1949). They were led to this idea while considering the potentially classical origins of some of the difficulties of quantum theory. Consider the following problem from classical electrodynamics: an accelerating electron emits electromagnetic radiation and, through this process, the acceleration of the electron is damped. Various attempts to account for this phenomenon in terms of the classical theory of electrodynamics lacked either empirical adequacy or a coherent physical interpretation. Wheeler and Feynman attempted to remedy this situation by reinterpreting Dirac’s (1938) theory of radiating electrons.
