I don't know the maths, but I think I understand the principle.
General
relativity predicts that space in the vicinity of massive bodies is
curved,
or non-Euclidean, like the surface of a sphere or a saddle. This will
effectively change the value of pi, as defined as the ratio of a
circle's
circumference to its diameter, and make the angles of a triangle
sum to a
value ofther than 180 degrees. You can see this on the surface of
the Earth
Yes, except that conventionally pi is a constant, so you should be
saying that the ratio of tyhe circumference to diameter becomes less
than
pi. Just a small nit picked.
Just about all of modern maths goes out the window if pi changes
value, as nearly happened in Indiana
(http://en.wikipedia.org/wiki/Indiana_Pi_Bill)
Actually, that is a rather instructive example of crackpottery!
Interesting indeed.
