SexWarrior, that is precisely the type of "proof" that the video I linked above shows to be false. Essentially, when you repeat that to infinity, you don't get a circle, you get an infinitely-sided polygon with really scrunched up sides. (I *think* Miles Mathis's proof of basically the same, but he does a whole lot more math to get there.)
Except that circles do not actually exist in this universe, since the universe is quantized, space ultimately existing as discrete plank length units.
Does every discussion with you have to end in absurdity yes, in the limit "circles do not actually exist in this universe", but in any practical situation they certainly do. And, in for example the calculating length of the equator, the equator is an
imaginary line anyway, so I will choose to measure it (figuratively speaking) with a
1 km long plank!
Your measurements might be in "plank length units"! Is that a 2 m plank, though I usually use a 3 m plank for painting.
For very tiny measurements the Planck Length (1.6 x 10
-35 m) might be more appropriate.
I does seem strange that you seem familiar with the Planck Length which is defined as
when you presumably deny gravitation and hence the presumably the graviatational constant G.
But, more seriously! I do think you just trying de-rail any argument with comments like that.
Taken on a small enough scale the perimeter of any object takes an almost fractal nature and has an unlimited size.
When doing practical measurements, and that is what I am interested in even if you are not, we select an appropriate resolution.
