@layman,
meanwhile, in the real world, none of you guys can explain any of the problems I raised here.
No one can explain how or why it could possibly have any effects on physical processes, to take measurements from here, or over there, from this place beside this rock, or from that place on fast rocket.
No vantage point for taking measurements can possibly cause the merest hint of any real changes to any physical processes.
Time, length and mass can never be warped simply because some idiot takes measurement for some other position moving or not.
Imaginary "inertial frames of reference" are IMAGINERY, as is the ABSOLUTE origin and frame of reference, its able to be imaginary too, if I want it to be "here", then here it is, and its valid for the experiment I'm doing.
If anyone here in this forum thinks that imaginary reference frames can change physical properties and affect physical processes, then he is delusional.
Argue all you want about the meaning of Math, but math cant prove anything other than math is able to support almost any theory. Its like silly putty, mold it to what shape you want.
