I donno. Perhaps it's because there are three deities -- Ying, Yang, and Melvin. [That's a joke, A-Girl. I really can't answer your question. Hugs!]
When I said changing balance between dark energy and dark mass (accelerating universe) I should have mentioned that when the dark energy is greater the universe accelerates, when it is less, it decelerates and astronomy currently indicates a history of both (and perhaps several changes) my question concerns the triggering mechanism for the change.
The three generations of quarks and leptons and three gauge forces question is similar. What was the triggering mechanism to stop at three?
I realize you cant answer these questions. I can't either, but I am hopeful that well learn more as FermiLab and CERN continue in their research.
My objective with the examples is to illustrate the type of algorithm I seek in my hypothesis (algorithm at inception is proof of intelligent design) - i.e. more than a single step equation.
