You make a lot of this dynamic between past and future. As I understand it, the flow of time isn’t necessarily real in physics. There’s one view that says both what we call past and future exist simultaneously as a block of spacetime which comprises the whole universe from start to finish at once. The flow of time is an illusion.

An alternative view is that only the present exists and what we call the past and future are unreal. We remember the past and expect the future only in our present mental states. The talk of past and future would be pragmatic as we try to explain the changing present.

My question, then, is whether your talk of the flows from past to future and from future to past is meant as a figure of speech or whether you mean to commit yourself to saying that there really are such reverse flows.
