I really appreciate your very thoughtful approach and all of the work that you have done. I agree that saying I understand the body of your work is probably a little too strong of a statement to make...
You use many compounded questions in your statements and see nothing wrong with explaining definitions. You say that time has no definition since it is a duration that defines time...and what is a duration? Why of course, a period of time. You deny a definition of time, then use a synonym for time, duration, and then seem to claim that there is some hidden truth or meaning to defining time as time or a definition as a definition or any number of other conundrums.
In fact, there have been many books written about such topics as the meaning of nothing and those writers are equally convinced that they have revealed some hidden truths about absolutely nothing. There are many math examples that show 0 = 0 or that 1 = 1 in very complex ways that seem to have meaning, but are much ado about nothing as well.
Prediction of action is what is important, not explanations of definitions. You have used the deflection of a photon to define gravity. This is fine except for the factor of two needed to explain why a photon gravity is twice regular gravity. You do not even bother to mention this.
Your theory of everything does not mention quantum phase or entanglement or decoherence. All your equations do is reformulate the existing algebra of classical physics. Since you cannot seem to see that simple fact, it is a very deep rabbit hole that you are in.
What is temperature? Temperature is energy and energy is mass. Something that is hotter weighs more than something that is colder. Temperature is not hard since it is not axiomatic. The mass that defines temperature is hard because mass is what everything is made of and mass is simply something in which we must believe. Mass is simply mass, an identity. Likewise for action. Action has no definition and is a pure belief or identity. Action is simply action.
These are axioms and are part of our self evident reality. You choose to use more complex axioms, but you also have a simple set of beliefs. There are a large number of different ways of describing the universe and as long as you predict action well, there is nothing wrong with your method. However, a simpler set of axioms is better and so matter and action are much better since they are simple and easy to communicate.
You claim that quantum entanglement implies instantaneous communication between two observers, but all communication is limited by the speed of light. What you evidently mean is that quantum entanglement implies that classical cause and effect is limited between an observer and a source, which is true. However, that does not mean that two observers can communicate faster than the speed of light. Rather, it simply means that an observer cannot precisely know the cause of every action. Some causes in the quantum universe are simply unknowable by classical methods, but we still can predict the actions of sources pretty well despite the quantum limitations of what we can know.
