Brief and simplified suggestion to complement recent discernment https://www.epistemologyontologyfoundationinstitute.org/nature-decode/on-philosophy-and-science-of-the-wave-
function. And as well as diverse past discernments:
Causality and retro-causality have been of great wonder or mysteries across philosophical and scientific spectra. However, the solution, despite of great or complexity literally out of the known physical world (which also implied hidden and subtle aspects), is to develop based on the concept of "Dependent and Interdependent Origination", "Dependent and Interdependent Arising", and "Sum of Parts of the Greater Whole. And the Whole is Far Greater Than Sum of Its Parts". And which implied not only non-linear nor simple interdependent and interconnected mechanism, rather beyond or as intertwined and entangled universal process of being and becoming of sum of parts of the greater whole as wholeness of oneness. And which also implied causality and retro-causality are irreducible. Otherwise, it would be impossible to comprehend.
In philosophical content and context, the closest would be irreducible Dharma-Karma concept or philosophy.
