• Dark numbers destroy the diagonal proof

    An infinite digit sequence cannot contain only identifiable digits. We
    see this by reflecting an infinite sequence like -C = 3.1415... at the
    decimal point. The integer part of the reflected number ...5141.3 cannot
    be determined. Every integer with digits at only identifiable positions
    is defined. -C must have dark digits. They destroy Cantor's diagonal
    argument.
