The thing is that space and time exist INDEPENDENT of humans.But you define tham via human perseption.
Remove humans  and all the physics of spacetime remains the same.
Also, you can not define time (or space) ONLY as a set of numbers as you did in your hypothesis  this is too broad definition, because anything which can be expressed mathematically is a set of numbers.
As I told you before, there are some errors in your math (like deltafunction in eq 1.21 can not be equal to 1 unless z=c).
Some time ago you claimed, that your hypothesis yeilds the value of Plank constant (or origin of Heizenberg uncertainty principle  both are central to quantum mechanics), but I did not find that in your writing. Instead, you simply put known value of h (and c) in your theory "ad hoc" (by hands) multiplying eq 215 by hc to make Shredinger equation out of it.
Shredinger equation in QM is usually derived by minimizing pathintegral (using least action).
In Ch. 3 you just copy relativity textbooks (adding a concept of "center of mass" which is completely irrelevant to SR)  and you copy it "in reverse"  from constancy of c to Lorentz transformations, although correct way is vice versa  from fundamental symmetry (invariance) of spacetime interval under continious rotations (in spacetime) to the Lorents transformations and the constancy of c as a consequence.
And, again, there is no such thing as a "center of mass of the Universe" (which in your hypothesis is a consequense of your incorrect definition of time).
Sincerely, Alex.
