I agree that the value of the circumference of a circle to is radius will approach pi locally for a small enough circle. While this is true and that every 'point' in space is flat, beyond a 'point' space is not flat and can take different forms. (Every point on the surface on Earth is flat, but...

I was reading up on this at the link below. http://www.maxwells-equations.com/materials/permeability.php at this site I saw that permeability in a vacuum is defined as μ=4(pi).10(exp-7) which is what got me confused?

Pi is constant only in Euclidian geometry / space. Pi is defined as the number of times the diameter of a circle divides into the circumference. If flat Euclidean space that is 3.14 and remains constant. However, space time is not a flat Euclidean space. It can be curved (by the presence of...

As per Maxwell's equations the speed of light is c = 1/√(permeability X permittivity) I find that both permeability and permittivity have pi in their calculations. Since spacetime is not flat, the value of pi would change due to the curvature of space near large masses. Does this mean...
