Regarding the

Vorpal Blade hater's

writeup, the following should be pointed out about the

value of

pi: The

constant pi refers to the

ratio between certain geometric aspects of a

circle in

Euclidian space! But as we know, real

space is

noneuclidian. This is

Bad News for any claims regarding the invariance of, say, the ratio of a

blood vessel's

cross section to its

radius (assuming the radius controls the

pressure in this manner). Since this cross-section lives in a noneuclidian geometry, it is subject to change according to the

local curvature tensor (or even just

curvature, if you just want to do this in

3 dimensions). In other words, it is not constant!

We may therefore conclude that standing near a black hole might not be such a Good Idea. In the past, I placed a few warning signs near them, but somehow they all vanished.
