it blows my mind that this is a symposium that the university of san diego is putting on for two days
its description starts as such
"Causality, the notion that earlier events can affect later events but not vice-versa, undergirds our experience of reality and physical law. Causality is predicated on the forward unidirectionality of time. However, most physical laws are time symmetric; that is, they formally and equally admit both time-forward and time-reverse solutions. Time-reverse solutions are distressing because they would allow the future to influence the past, i.e., reverse (retro-) causation. Why time-forward solutions are preferentially observed in nature remains an unresolved problem in physics. (While the most convincing explanations invoke the second law of thermodynamics, wavefunction collapse or the expansion of the universe, in the end, purely forward causation is an ad-hoc physical assumption.)"
