Why?
If you believe there is an error in what I have said, identify it.
Or give me at least a hint. As a start, my argument rests on two observations:
1. Cantor's diagonal construction, when applied to a purported list of all computable Reals, will produce a computable Real not on the list. Therefore you cannot provide a list of all computable numbers.
