Which is a whole different thing from
floating.around.the.universe mumbo.jumbo.
You can't prove that
there is no x e IR such that x = 1/0.

This is why I drone on and on about definitions:
If we give a definition of
what a non.existing thing allegedly is,
in a language which describes existing things,
we can prove by contradiction that
it isn't one of those existing things.
Translate ¬∃ᴿx = 1/0
to ¬∃ᴿx: 0⋅x = 1
Prove that.
