Hello Jayakar ,
I have always thought the same, that the zero doesn't exist physically speaking .You know I love maths but I think many confusions appear due to the used tools .There it is logic to have constrains if the strings are inserted ,on the other side this perfect balance between forces in its evolutive harmonization has no constrain .The constrain is just an invention of the human ,thus we invent several models to encircle the cause of this constrain ,but in globality ,these constrains don't exist .Thus why to invent them .
You say
"I think we may have to re-configure Planck time with elementary volume rotation, in that hidden variables are essentials as durations."
It is relevant about this planck scale ,the volume is a main part with the rotation of the puzzle .I am not too a supporter of the hidden variables implying a duration for exemple ,simply because I consider in my model some universal constants and irreversibilities .The time ,the mass ,....don't change their sequences due to the ultim intrinsic code of the main center in my opinion .
I am curious dear Jayakar but why do you consider the strings like foundamentals ,it exists many tools to understand our Universe and many physicians and pepole have invented beautiful axioms ,my favorite are simply Newton ,Copernic ,Gallilei ,Bohr,Maxwell,Hubble,....only the real foundamentals are necessary ,furthermore with these laws ,equations ,axioms ,...all is synchronized ,never a confusion appears with the good tools .
I see simply that the strings imply the confusion about the real physicality and its relations .
Thanks for the discussion dear Jayakar
Best Regards
Steve
