If you thought Time was a past-to-future arrow, think again.
This mind-blowing translation of the workings of Time drifted from the ether of Wheeler-Feynman Absorber Theory, which found that particles such as electrons don’t restrict themselves to the forward-moving arrow of time we perceive, but are subject to equal demands from the past and the future, via waves known as ‘advanced’ (those coming from the future) and ‘retarded’ (those coming from the past). This enables electrons to behave the way they do, both electronically and electro-magnetically. The ‘absorber’ part of the theory describes the process by which time is essentially ‘absorbed’ within the wave packet of the electron, allowing it to operate in real-time as if the present moment were the only one to exist. Here, an article goes into more depth about the implications of retrocausality, where "getting rid of Einsteins' spooky action at a distance" actually implies that non-locality and time symmetry are connected.
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.
