From Cantor. > > The computable Reals cannot be listed. > > Therefore according to you they are uncountable.
Also according to Cantor. He said (in a letter to Hilbert) that uncompuatble numbers are nonsense (he actually said infinite definitions are nonsense, but that is the same) and of course he is right.

No. There is no uncountability. That needs to be understood. Uncomputable numbers are not numbers, because nobody knows what they are.
