Yet our observation of this upward process is downward. How might that affect what we see? Does it impose form, definition, constraints to a process, a dynamic, that might not otherwise be as clear? It does seem that's one of the mysteries of QM.

How might we consider this relationship between the process and the patterns we observe? The energy driving it is necessary, yet any form it manifests is only by the limits of this energy. Such as the frequencies and amplitudes of waves are an...


The problem does seem to be with the conceptual ontology of causation, maybe time, rather than the composition of the physical per se. Emergent properties with "downward causal impacts" seem to exist, but are still fallible to David Hume's early criticisms of Newton's cause-effect laws. Those criticisms still haven't sufficiently been answered.


Re: “Let's say you are a universe raising particles, who are you going to get to babysit them … A real particle that has given good service to the parent universe for a very long time may be given the opportunity to be born again in a new big bang and become a new conscious universe that can join universe society as a new member and raise particles of its own”:

Aww how cute: Baby particles!
