Yup. Points are fictionals as are infinities 0D, 1D, 2D, 3D are
all fictional.
As far as we know at present, everything in the Universe is 4D
at minimum. It's rather ridiculous, in a sense, talking about
an infinity without referring to an infinity [of what], as if an
infinity stands by itself.
Seems to me, a problem of reification here.. [unless you believe
in the Platonic realm, which is, of course your right to believe
in if you wish] Prior to mathematics, you have geometry. At the
root of geometry is axioms and proofs.
At the root of axioms is.... We need to dream and inspire.
But when the dreams and inspirations are being treated as
science fact rather than science fiction, it's immoral to teach
it that way.
