The idea I have is a sphere (I know, it's been done. I came up with it before reading the cliche list) who's volume, radius and circumference only make sense if Pi is exactly 3.00 instead of 3.1415 etc. In an three metre sphere around it the value of pi is three affecting all formulae which contain or equate to pi or it's multiples, objects both living and not would warp or bend to try and fit this new reality while any written statements related to pi are altered as well (eg. Pi=3.1415 changes to Pi=3.0000)
Is this idea any good, and more importantly has it been done before? As a side question what formulae would this affect and how would objects be affected by this change?
