I am glad you asked (me:-) that. Pi exists in every circle, since is
the ratio of great importance. Circles exist, don't they?

As for "spacetime", looks like it has had it's day, as a mathematical
abstraction from reality. Meanwhile, I must get back to "Superstrings:
A Theory of everything" by F. David Peat... you'll believe a "point"
can spin!

          I didn't get where I am today by not recognising
               a cotangent bundle when I see one.
