No, you still misunderstand me ;-) not correspond in the sense of
non-existing, not in the sense of existing but not number.

The idea was that the numbers encode moments which don't have successors
(the guy who transports), that's why there exist alien-OMs encoded in
numbers which destroy all the machines (if we assume that arithmetic is
consistent).

This is the issue at stake: from what do you gather that all machine
states have a continuum of successor states (the aleph_0/aleph_1 is not
at issue now; it suffices to say: at least one successor state)?

After all, there are halting computations.
