Roger,
I agree that they are not there yet. I checked your website. (Mine is very old, not up-to-date; physics of time speed)
Your grouping needs to be defined by a rule of impossibility in order to make it a truth system. From one impossibility all the possibilities will emerge. I mean, if everything and anything goes, well, we end up with no laws of physics no rules of logic etc. The impossibility to go faster than light is the impossibility from which Special relativity is born; all conclusions emerge from this fact or postulate. The impossibility to distinguish between gravity and inertia is the impossibility where general relativity begins. As you can see, they are both successful truth system but they emerge from different starting-defining impossibilities, usually very difficult to reconcile. (e.g. gravity vs QM)
In my model, the rule of non-contradiction (impossibility) defines the only possible exitent in it. Nothing else but the passage of time may exist in it without leading to a contradiction, i.e. existence and non existence cannot be at the same time... unless they are never found at the same time! The passage of time is an explosive process that meets the requirement. A contradiction that is never tested because never found at the same time. This passage of time is the substance. Well, you could call it anything since it makes everything, but, being a SUBSTANCE, we have no direct experience of it. Except within our own perception of time passed, due to consciousness and memory. These two attributes allow us to sense the substance and its effect on everything; motion, past present etc.
We have the rule of impossibility and the substance. We still need one rule of operation that must be built into a property of the substance itself. Here it is. Existence is more probable where time runs slower. (gravity) This is the only causal rule necessary for the whole system, including its expansion. (nothingness = no time = "slowest time" possible = spontaneous motion in all directions aka explosive).
In this model, we are not present as observers and the way we see and conceive up things to be is not interfering. This universe works by itself as it should.
Causality is all. Crunching the numbers is on a want to know basis.
If the universe is so simple, it should be explained in simple terms anyone on the street can grasp...
