Chronological Symmetry

Raum-Zeit-Punkt

In the here & now we are present, and there is a (my) truth in this space-time point.
(That is why it is so important to keep going back to the here & now).
Starting from this point (in the pasta image the loop) there is a bundle of future options, of possibilities. A potential, therefore.

For example:
I am sitting here at the table and eating a sandwich.
The future could be: I order another one. I order a coffee. I pay and leave. And many more options, a potential bundle, therefore.

Since the universe is based on symmetry (hermetic laws, etc.), shouldn’t the bundle also extend into the past? Further thought, is there also a potential bundle extending into the past?
One might initially reject this as an idea, right? “The past was just the same, and for everyone…”

And what if not?
(This can also be nicely visualized with Mikado)
