What do you mean by "after all THE problem?" Do you mean "it is still a problem"
or "understanding of time is always a problem that cannot be understood?"

Agreed.

I agree completely.

Your TGD may be one candidate for a solution and it is good as such. I myself am
trying to give an understanding of the problem by considering the role of
subjectivity in physics, whose existence has been ignored in physics or at least
physics has been pretending to think that "subjectivity" is not a subject of
physics. I recognize here some points common to your TGD and my theory.
Best wishes,
Hitoshi
