Well, the reason for the seemingly weird question is this.
Pi represents a measurement of 2d to 1d ratio, if we were in a curved spacetime, say on an apple surface, the value of Pi would be different.
So my real thought is, is Pi actually 3.0, and the .14159 just an effect of the expansion of...
Ok,
This probably seems a silly question, but has there been any 'serious' attempt to measure Pi PHYSICALLY, like in a lab, using say a light fiber in a circle and one down the radius?
If so, where can I find the results/paper?
Thanks!
What is the equation for how a light beam is bent by a mass?
Say a mass M way out in space, and a light beam is aimed from VERY far away such that it should pass at a radius R from the mass.
