You always ask the simplest darn hard questions...
"- Does the the Fibonacci series have a final finite end as you say, and does this have a size? Does the series also have a finite end on the large scale or could it be infinite?"
The Fibonacci does indeed have a finite end as two one tiles. While most suppose the series begins with two ones, it is equally valid for a Fibonacci series to end in two one tiles and that is my universe.
The Fibonacci universe has a very large but finite number of particles when collapse begins and we are only through about 1/3 of the contraction pulse. At our destiny of two, an antiverse expansion begins with antimatter and antilight and antigravity until the next contraction pulse.
"- Any ideas what the fundamental 'qualia' could be?"
Each object that we sense has the qualia that we associate with related objects. Red, bright, large, and so on. Every object and every action in the universe is related to the fundamental qualia of the universe axioms: matter, time, and action.
"- In your claim, that calculus has resolved Zeno's paradox, would you know the size of the final infinitesimal step, because surely it must be taken to complete the race?"
I perhaps should have been more explicit...but there were only nine pages in which to cram way too many ideas. Calculus provides the math tools that allow us to deal with the infinitesimal and that is what I meant by resolve.
You are still very correct to point out that the Zeno's notion of infinitesimal points in space still results in difficulties in science. The whole mythology of black holes is based on these kinds of paradoxes. Of course, matter time sidesteps all of that silliness with the idea of space that emerges from action and time, not the other way around.
In a finite universe where action is driven by exchange of finite bits of matter, there is no problem in completing any motion including the race you mention. Although that is not yet the universe of mainstream science, that is my universe.
"- Finally, how would you cut a 'real' or 'platonic' line in a perfect mathematical universe as you call it? Taking note that by definition a 'point' is uncuttable."
A perfect math universe is perfectly suited to the infinities of the infinitesimal. In other words, we can imagine and believe in infinities all we want to. As long as beliefs do not threaten our survival or preclude an accurate prediction of action, beliefs can range.
However, when it comes to a more accurate prediction of action, the finite point that we use is the point that provides a prediction of action with an acceptable uncertainty.
