There does not exist a complete computer model of the economy of Australia
How do you know?
I am of the opinion there are many computer simulations of economies, utilizing many different economic theories.
When I attended Fresno State University in 1981, we did computer modeling in my Macro Economic class (actually using PUNCH CARDS for data entry!!! LMFAO!!!)
Please provide evidence of your assertion.
Plus, there are no competing theories on regard to the heliocentric model. You have an accepted theory governed by specific Laws of Motion and Thermodynamics.
nor a model of ridership on the tube wrt each individual;
Why would a model of any subway be broken down to the individual riders?
A demographic model would be of far more value.
nor a model of the electrical wiring in the Louvre.
Well, this is just about the most ridiculous claim I have ever seen in my life.
Does not even deserve an answer.
As an aside, the models which you are proposing are so far removed from the CGI rendering of the Solar System it could be considered quite meaningless as a base for arguing the issue.
That models of these things have yet to be made
A dubious claim which requires more evidence than your word, I am afraid.
is not evidence that economists don't understand Australia, nor urban planners the tube, nor electricians the Louvre. At best, it is evidence that making these models is not necessary to prove they exist nor to understand them effectively.
You need more evidence models do not exist.
So it is with the solar system; or it would be, except that computer models of it do exist, as so many examples were given in the previous thread you made on this exact topic, that went so well.
None of which fit the bill.
I again present solarsystemscope.com to the forum, and again decline to participate further in this highly-regarded shitshow.
It would be smart of you to decline further participation as your argumentation is flawed and baseless. Your model is in the wrong thread. Plus, it has no verified pedigree. Plus the rest of the forum disavowed your model as accurate.
