Asymmetry of Time Symmetry by Eric Aspling

Hi Eric,

Your excellent essay clearly presents a fundamental conflict about time. This conflict arises from the determinism and time-reversibility of physical reality. Determinism and time-symmetry are not mandated by empirical facts, however. Resolving this conflict requires an analysis of the assumptions underlying fundamental determinism and time-symmetry.

My essay presents an alternative model that is consistent with empirical facts, in which randomness and asymmetry are fundamental. As further developed in a referenced essay (Reinventing Time), this alternative model can accommodate both CTRS and LTRS as distinct special cases.

Dear Dr. Eric Aspling,

Your Logical thought experiment is very good!!! Your words.......................Under the first interpretation, you have truly reversed time in which Schwartz tells us particles become antiparticles traveling backward in time...........

Confusion arises when anti particle annihilates with a particle of same type, it will result in eternal NOW???

In "Dynamic Universe Model" time is having only positive direction as we see on earth. See for further details see my essay .....

I am looking for your comments please

Interesting, well written essay on the nature of time.

However, your essay does not mention the word "entropy", which is central to defining the arrow of time in many-body systems. This relates strongly to probability - a glass shattering into a thousand pieces is highly probable, whereas the pieces spontaneously reassembling is virtually impossible. Past and future are clearly distinguishable in a many-body system.

A very interesting topic actually. Your essay is amazing, I don't even know if I could ever do something like that. When I had problems writing any paper mainly for college I used https://papersowl.com/fast-essay-writing service since I am not very strong in this area. Fast essay writing service helped me in my physics classes because sometimes I had problems with the correct expression of my thoughts through creative work. Your work is inspiring.

Dear Eric,

Very good essay about Time and conundrums around it.

All problems arise from the fact that time is considered as some independent substance that flows (passes), in which you can move forward or backward. In reality Time itself does not exist. There are only motions. Motion is used as the time standard. The time is handy way to compare motions. Universal time (expansion rate of Universe) is irreversible. Local movements can be reversible, i.e., the local time can be reversible. More in: About Arrow of Time. http://viXra.org/abs/1902.0495.

According to the principle of symmetry, the antimatter must have a negative mass which repels ordinary matter. Therefore local time of antiparticles in comparison with Universal time is negative, i.e., direction from Future to Past.

Hi Eric, it's great to see an entry from you in the contest! This is actually something I have thought about for many years. I'll have to send you some of the things I've considered. I'm of the opinion that, at least from a pseudo-operationalist standpoint, time-reversal symmetry doesn't make any real sense and only CPT-reversal actually accomplishes what we expect. But CPT as an operation is necessarily anti-unitary which seemingly creates a problem.

Eric:

Confusion about the nature of time insures questions about physical reality will continue.聽 And puzzles about physical reality promise puzzling opinions will continue with "time."聽 Examining the nature of what is called time is an excellent way to solve a multitude of聽 physical mysteries.

I find your essay confusing, but doubly so because you commit the heinous sin of casting your argument in the language of flowing or passing time, conflating the passage of time with time asymmetry. Right at the outset you write: 'If you proceed with time moving

forward again, what do you see?' Time moving? Time cannot and does not move. Time simply is. (How fast does your time move? One second per second?) The flow of time is a psychological illusion; time asymmetry is a property of matter, not time.

Dear Eric,

I believe the 'flow of time' is a most important concept in physics. Not to be confused with Prof. Davies human subjective flow, which he mentioned above.

Einstein's relativity has taught us that the flow of time varies across space according to the energy embodied in that space. In this way we can conceptualise the flow of time as a sort of time dilation map of the universe which will generally accord with a gravitational map, but with a twist if you entertain the idea of an aether, as the energy of motion will also be integrated into the time-flow map.

Check out my essay which has a section on time reversal, as well as a new slant on presentism.

Erik,

Interesting and original approach. Nicely written. Do you consider reversing a reversible physical process to return a state to it's previous condition, has any parallel with time reversal? e.g.

Take a polarising interaction; absorption/re-emission where the polariser electron has some polarity and changes the state interacting with it, which is what's found (i.e. Zeilinger ref in my essay, where it has 'no memory of it's previous state'). An inverse electron polarity, at the photomultiplier for instance, could then return it to it's original state (or the same one repeated just 'square' the new amplitude).

Sorry that got a bit complicated! But do you think states can revert (or keep being changed) while time just ticks on in no particular 'direction'?

I've suggested it can and show in my essay that seems to bring exceptional resolving power!

Nicely done for yours.

Very best

Peter

Hi Eric,

I will try to remember to e-mail you some stuff. If I forget, just pester me.

Thanks for the information.
