Modest, I want you to know that your interest is very important to me. Above you I might only place Qfwfq and Erasmus00 but Qfwfq has apparently found other interests and Erasmus00 seems to have found questioning modern physics to be blasphemy. I appreciate very much the willingness to examine other possibilities.

Change in information is change in information;
the actual “t” index assigned to that change in information is an open issue. I have not defined that assignment. The actual assignment is to be provided by the explanation. The definitions, as I have given them, are still open.

With an explanation involving the nature of video cameras and coins and patterns of that sort we can predict another subset of information—the heads/tails value of the actual coin.
When the information changes we now have a coin spinning on the table. The camera’s memory and screen contain no subset of information revealing the coin’s value.

I am afraid that you have misinterpreted what is meant by “the past is the information available”.

There is a very great difference between “the information available” and the information contained in a particular present. What is or what is not available to the production of an explanation is quite a different issue.

Yes, I am quite aware of this issue and I actually find it to be a distraction from the central issue. I hope you can recognize the problem embedded in the attitude expressed here.

Of course I think I do; however, it is your opinion which of interest here. Do you think I understand what you mean?
Have fun -- Dick
