Oh I can show what nothing is poetically. Whether you agree that
   it is nothing that I am showing you would be an issue, but such
   is the same with mathematics or philosophy or anything a human
   attempts to convince another human of. Square circle is doable
   as well. Again - depends on the constraints of the system. You
   might not LIKE my examples of square circles but they'll be
   correct, because I will have shifted the context.
