    Better question: What curvature of space is necessary for the apparent value of π to be 5?

    ~~honestly I don’t know if there is any way to measure curvature of space , but its slightly more curved than the surface of a ball (where π=4.712)~

    edit : its more complex than that and topology of non euclidean spaces hurts

      Kind of curious how you got that value. I think the ratio of circumference to diameter (“pi”) is actually smaller in spherical geometry, in the most extreme case (the equator) it’s just 1. You could say “pi = 5” for circles of a specific radius in hyperbolic geometry, I guess.

        my mistake was using the sum of angles in a triangle which was kinda dum but whatever . I also tried calculating via the circumstance of a circle placed at a pole where π was 20x smaller for the case I was using but its not linear so I looked deeper which was a big mistake .

        BTW the ratio of circumstance to radius for a circle which is also an equator of the space is ¼ not 1 (r=½π₀ , C=2π₀) .

          I think you mean 4, which makes the ratio of circumference to diameter 2 (either way, no idea how I messed up that one).
