Wikipedia -Retrocausality (also called retro-causation, retro-chronal causation, backward causation, and similar terms) is any of several hypothetical phenomena or processes that reverse causality, allowing an effect to occur before its cause.
Retrocausality is primarily a thought experiment in philosophy of science based on elements of physics, addressing the question: Can the future affect the present, and can the present affect the past? Philosophical considerations of time travel often address the same issues as retrocausality, as do treatments of the subject in fiction, although the two terms are not universally synonymous.
A few legitimate physical theories have sometimes been interpreted as leading to retrocausality. This is not considered part of science, since the distinction between cause and effect in physics is not made at the most fundamental level
Scott Aaronson is trying to completely sidesteps the “mystery” of free will and determinism, in much the same way that an NP-completeness proof sidesteps the mystery of P versus NP.
