Your actual assertion was that you stated an experiment to test your assertion so:

IF08: State your experiment that tests your assertion: no spacetime is possible without observer. Give the results of running that experiment.

Which reminds me that these questions need to be answered after you cut and paste your PDF into the thread.

IF01: Show how you derive Newton's laws from your theory (include your work) (N.B. this is not a F=ma equation appearing out of nowhere).

IF02: Show how you derive the Schrodinger equation from your theory (include your work).

IF03: Show how you derive the Dirac equation from your theory (include your work).

IF04: Start with "assume vector nature of electromagnetic field," and show how you derive Maxwell's equations (include your work).

IF05: Show how you derive relativity of simultaneity from your theory (include your work).

IF06: Give your derivation of curved spacetime from your theory (show your working).

IF07: Show your step by step building of "Minkowski spacetime on basis of Euclidean space"
