Should I say "Scroll down"?
I've explained about UA repeatedly also the illogical things about gravity.
I wish FE websites had put my concepts about UA in their FAQ.
You have explained nothing about gravity. The problem is you have a tendency to ignore reality, case in point is your problem with pi.
The world is built using pi,3.14159265359, etc, Every rotating piece of machinery that has ever existed or will exist or any round or curved component ever manufactured or will be manufactured has used pi or will use pi to calculate its dimensions.
So far everything in the world works fine as there is no problem with pi, regardless of your constant unsupported claims.
If you have a car do the pistons not move with ease inside the engine block?...if the answer is yes then there is no problem with pi, just as there is no problem with gravity. Its just a couple of random thoughts you have in your head that have no basis in reality.
