Blog 20190529 "Time reversal" a product of regressive desperation
Jesse
and Piotr commented on this silly article in Newsweek:
Scientists Have
Reversed Time in a Quantum Computer.

Jesse:
“These
people are so far out there. My kid has his building blocks scattered all over
when he dumps them out. I (a program macrocosm) put them together in a
structure. Then he knocks them all down again. Depending on how complex it is.
I can generally reassemble the same way.
Me and my kid reversed time.
These people are just idiots. I can’t mince words anymore.”

Piotr:
“There
is a pattern here: the more they are stuck in their research, the more
ridiculous ideas they publish.
It's
desperation.”

I agree. You don’t need a computer to “prove time reversal” occurs—as long as
you forget about the macrocosm. The experiment involves a
typical violation of the 6th assumption of science complementarity
(All things are subject to divergence and convergence from other things). On
Earth, plants live and die. They grow when they receive converging sunlight;
they die when they don’t. That is what regressives do when they write about the
“heat death of the universe,” assuming that the observed universe is finite and
has nothing outside it.
And of course, it is a blatant violation of the 7th
assumption of
science, irreversibility (All processes are irreversible). Any experiment I have ever done
required outside inputs to obtain a former state. The sci-fi dream of “going
back in time” is rampant among regressives and their followers. It is easy to
demonstrate how fallacious it is whenever you include the macrocosm in your
analysis. For instance, the night sky is unique. Celestial objects, being in
constant motion, do not appear in the same locations two nights in succession.
To go “back in time” even one day would require you to move each of those
objects back to their former positions. Good luck with that!]

If there are novices reading this they should know that Thermodynamics ONLY includes closed systems. The Universe is not a closed system.
Also, physical materialists are all determinists, I believe. This means, among other ideas, that cause and effect move only in the direction of time. The universe evolves, it does not change its arrow of time. That is impossible
Bligh:
Thanks for the comment. You are correct, although I try to avoid the "direction of time" phraseology. Time is motion. Universal motion is the motion of each xyz portion of the infinite universe with respect to all other portions. Those motions are sometimes toward and sometimes away from other portions. Also, evolution is motion, so I would not say the universe evolves, although each of the portions evolve.
