Hi Jim, the choice you offer is black or white. The problem is a little more complex. You have made the assumption that when we consider time it is of just the one kind, 'time is time' so to say. So can only be accepted or rejected. However there is also -'it depends' (on what time is considered to be when answering.), or 'not necessarily'. I do agree with you when you say that "If time does not exist there are no pasts or futures somewhere."that prevents temporal paradox but it does require more to account for non simultaneity of observed events.

I like that your presentation is short. You have raised what you think are the most important fundamental issues and not dragged it out for the sake of it. Time is an extremely important issue. You have expressed your views clearly and reasonably. Personally, I don't think it has merely been the Earth's rotation that has caused confusion to humans but 'time' is a tricky conundrum involving different aspects of the universe and the relations between them, and with us. Kind regards Georgina

Hi Georgina,

I`m glad to hear that you found the choice "black or white". I worked at making it so.

Yes, I "made the assumption that when we consider time it is of just the one kind, `time is time` so to say."

I`m also glad that you liked that the presentation is short. Brevity seemed the best path towards clarity. As you said, I ...."raised what you think are the most important fundamental issues and not dragged it out for the sake of it."

Thank you especially for this quote, "You have expressed your views clearly and reasonably."

Thank you for your generous comments.

Dear Jim,

You say that time does not exist, but I think you mean something a bit different – that time is not a dimension like space. I would agree with that.

Further, you focus on the rotation of the earth as the basis for the perception of time. In fact, the diurnal rhythm is the basis for biological time, and all of our biological clocks are synched to it. The basis for the perception of past and future is in our minds, and does not depend on day and night.

Physical time is different, and is a parameter in dynamical equations. The treatment of time as a dimension was reinforced by the relativistic concept of 4-dimensional spacetime. In my own essay, I argue that spacetime is an unnecessary mathematical artifact, and that fundamental physical time is based on a rotation of a different sort – rotating vector fields associated with electron spin. Of course, this rotational period is about 10^-20 seconds, rather than a day.

Best Wishes,

Alan

Jim, you're good, I appreciate your essay for what you said to those who think that time is fundamental, that it is not. Fundamental is the moment between the past and the future and which is life. I'll give you a rating after your comment in my essay, in which I argue that space is a matter that we do not see, but which is. Sincerely, Dizhechko Boris Semyonovich.

Jim,

Love it! Strangely close to may own essays foundation of simply 'motion' mainly rotational. I hope you get to read it as the consequences are quite sensational.

Rather too brief, but you got the point across with clarity, and with some highlights none the less;

"Our clocks do not actually measure time passing, our clocks measure duration elapsing". ...and

" there is no possible time travel, since there would be no other times to travel to.

Thank god (whoever he is!) for clear vision and common sense.

Best

Peter
