Howsoever this may be, the fundamental principle of Retrocausality is that the future in some way affects the past, via the present moment; in other words, cause-and-effect works both ways.
While neither Wheeler nor Feynman remain alive to see the revival, it stands to reason that reworking our perception of Time is going to prove beneficial. There is no need, after all, to worry about a future that is going to happen anyway. Nor is there any need to grieve about the past (although we all catch ourselves doing this from time to time). Prior to arriving at references to Retrocausality, I’d been led to believe (as have many people) that Now is the only point that counts, and that while time is a flexible commodity (having very little to do with clocks), there is a future sketched out with allowance for variations (since Uncertainty has to have its say in there somewhere), according to a grander scheme of things than we are given to imagine. We’re simply not permitted to know, for reasons known to greater powers, what it looks like. While most people could cite snippets of information about future events looking spookily like precognition, Uncertainty reigns in guarding the gates of things to come. However it may seem at the time, it's the timing of things beyond our control that makes the sum of a lifetime. We have scientists of the past to thank in providing sound platforms for the science of the future, where I’m absolutely certain we are all destined to share in the workable, worthwhile spoils.
