WM's misrepreetataion of it is the thing that is wrong, just like his misrepresentation of a simple bijection as being a homomorphism of linear spaces. > > > > It is clear that you completely fail to understand > > that. > > Cantor failed to understand his proof too?
No, Only WM misundertands it.

WM may think that he thinks, but he is wrong.

What Cantor proved was that the existence of an infinite list of binary sequences proves its own incompleteness, thus no complete infinite list of binary sequences can exist:
THEOREM: IF there is a countable list of binary sequences, THEN that list is incomplete.
PROOF: GIVEN such a list, one can define from it a binary sequnce not in it.
The only way for Cantor's theorem to be false would require the existence of a complete infinite list.
So that in WMytheology, such a complete infinite binary list must exist. > > > Here it is again.

Then it follows that the hyporthesis is false and theorem is true!
***********************************************************************
WM has frequently claimed that a mapping from the set of all infinite binary sequences to the set of paths of a CIBT is a linear mapping. In order to show that such a mapping is a linear mapping, WM must first show that the set of all binary sequences is a vector space and that the set of paths of a CIBT is also a vector space, which he has not done and apparently cannot do, and then show that his mapping satisfies the linearity requirement that f(ax + by) = af(x) + bf(y), where a and b are arbitrary members of a field of scalars and x and y are f(x) and f(y) are vectors in suitable linear spaces.
By the way, WM, what are a, b, ax, by and ax+by when x and y are binary sequences?
If a = 1/3 and x is binary sequence, what is ax ? and if f(x) is a path in a CIBT, what is af(x)?
Until these and a few other issues are settled, WM will still have failed to justify his claim of a LINEAR mapping from the set (but not yet proved to be vector space) of binary sequences to the set (but not yet proved to be vector space) of paths ln a CIBT.
Just another of WM's many wild claims of what goes on in his WMytheology that he cannot back up.
