Talking about Pie... MMM pie....
No seriously... Pi IS A PHYSICAL CONSTANT.
You don't agree, Ok let me ask you a question then, What constant determines how curved space is (and i dont mean curved by gravity but) naturally curved so that to go in a straight line forever gets you back at your starting point.
If you still have trouble getting it, imagine space is a sphere, now draw a circle on that sphere, what is the new ratio between diameter and circumference dependent on (don't say the length of the radius, analogies don't work is EVERY aspect)
