Procedural/mechanistic viewpoint on the arrow of time

flèche du temps = arrow of time = (deep understanding synonym) causality bias = biais de causalité

**Procedural/mechanistic viewpoint** on the arrow of time

An egg is created by a single complicated procedure. We break the egg. If we run time backwards that doesn't lead to an egg as erroneously presented in popular science videos [1. quantum mechanics prohibits the collection of all the data we want in tandem, 2. broken eggs usually don't dwell inside a mechanism which produces eggs in reverse timeflow (chickens ARE correct mechanism for producing eggs in forward timeflow [replace chicken with universe])], but it leads to a humongous number of alternative configurations of atoms (a negligible percentage of solutions = reversed timelines leads to eggs).

Why? Because the egg is **procedurally** produced by the chicken mechanics. A timeflow reversal of a broken egg, doesn't start inside a mechanism created to guarantee a desired specific result.

The chicken procedurality/mechanism sounds stupid, but that way of thinking (more elaborately and mathematically presented) leads to the definition of the arrow of time.

Destroying a book created by a mechanism is a similar example, because the torn pages aren't put in the correct place of a well functioning mechanism. Thus the torn pages of a book which "experience" a reversed timeflow, would create a humongous amount of Everettian alternative molecular configurations; and correct books would be a negligible Everettian range of solutions (most solutions don't lead to books and correctly ordered books).

In the text above I didn't reveal that the constructor (see: constructor theory) of our Universe, works in forward solution series.... Hmm... The universe might work in reverse, but these solutions cancel out due to causality restrictions. But modern physics has gaps.

What would happen if we reversed the timeflow of the universe to see what would happen to a very recently broken egg?

A naive person would say: an infinite number of Everettian alternatives is possible, and a negligible number of alternative universes would produce a complete egg.

A more savvy thinker would have a different opinion. Reversing all forces is very simplistic. It's not an intricate mechanism. OK. You reversed the timeflow of the universe and all the forces on the chunks of the fragments. These forces have too simplistic paths, not complex enough to produce an egg. Thus not even a single alternative reality would result in an unbroken egg. Even a time-reversed universe has to obey the physical laws. We cannot have magical and specific outcome procedures way more energetic than quantum jitters and without the spatiotemporal conditioning for a Big Bang (which still doesn't immediately produce one egg, but many later on, with too much extras).

Also it's impossible to reverse the specifically defined forces without to define them by hitting-measuring them thus also causing many other changes; but OK, we may imagine we reversed some wavefunctional characteristics which don't lead to uncausally strictly defined outcomes; thus a huge number of Everettian alternatives will result in different universe-strains. If you hit glass on glass and eggshell on eggshell it usually doesn't create a well formed merger. It's a very simplistic procedure. Also gravity works against the whole process thus reversing the forces isn't enough.

Huge connectomes of quantum interactions start to behave classical-like because time reversals and other quantum phenomena are filtered out by quantum decoherence. Large quantum cohere objects (bars in the lab, degenerate stars, etc.) maintain some quantum properties but not those that will cause quantum decoherence (one explanation for neutron star earthquakes).

An overall Hubble volume (causality sphere; see: Hubble volume) causality bias connectome can lock the overall arrow of time in one direction, by cancelling out (Feynman's paths + quantum contextuality) the inverse direction of the arrow of time.
