It seems like we keep chasing "reality", and by "reality" I think Physicists would mean the apparent rules of quantum physics which we hope would (if applied) lead to all the apparent known rules of macro-physics.
However ... It seems like we have had to create a few things to do that:
1. Ideas and concepts that we can test .. in our heads .. these are "models" of "reality" in our human brains.
2. Metalanguages that we use to communicate these ideas to each other (Language, Maths & Diagrams).
3. A reasonable working framework of logic "the rules of logic" (e.g. if X is true then it can't be false).
Unfortunately it seems that we have to keep altering these human-brain invented subsystems to fit reality.
Even the very rules of logic do not seem stable and safe (i.e. because the whole logic system is recursive and built on it's own sand as per 1. 2. and 3. above) - they all depend on each other !
For example we now accept that things can be in one place and another place (statistically) until "the wave function collapses" (or to state that in English "until the time we test that thing and then know were it is/was and when it is/was to a presumed statistically known level of certainty/uncertainty).
Another example might be that in future we might have to accept that "events" have no "time" at all.
i.e. there is no time - that would be fun !
What I am hoping for is broad agreement or discussion from the clever folks here that "our universe" just exists ... and all of our physics and maths and logic are just human constructs that allow us to get by and almost understand things for a short while.
Also perhaps this is all just a diversion from what seems like the depressing truth that nothing that humans think or do can alter anything at all in the future at all as only random quantum state fluctuations can alter outcomes. We can't control these, and so we can't control our thoughts, or even choose our own lunch !
It seems that these choices just occur on a macro level as dictated by the way the physics was going to do anyway in the normal macro-physics way (only randomly altered by quantum events that we can't control).
Also ... what if the universe is just saying (oh crap somebody is going to test superposition) I had better invent an outcome, as there has to be one, and spread that new rule throughout the universe instantly ?
Oh well ... anybody got any ideas or comments to cheer everybody up ?
I would love to be wrong ... i.e. It's all a bit depressing !
"so it goes" ... kbo
