(1) The consistency of a rich enough system S cannot be proved in S.
Moreover,
(2) If S is consistent it is not complete
PROOF Of (1). If consistency of S can be proved at all, in general, it would be via constructing a model of S.
So, let me prove that a model of system S mentioned above cannot be proved within S . Instead of giving a proof covered with 20 tons of cold lava and obfuscating the whole issue, I will give you an example.
Let S be the system describing the planet Earth. It is impossible to construct a model, i.e., a GLOBE, G on planet Earth which will model the (new) planet Earth system S + G . Because now on planet Earth you have put a Globe G and that glob G which was supposed to model planet Earth does not describe S + G. (and no finitely many repetition of S+ G+ G' + ...+G' will do the job). However, the consistency of S can be proved outside S. Indeed on planet Moon you can construct the Globe G which will faithfully describe S.
PROOF OF (2). If the system S mentioned above is consistent then it is not complete. Indeed, you can always enlarge S to the a consistent system S+H where H is a Globe of S constructed on the Moon, and repeat the process to show that you will never obtain a complete consistent system extending a sufficiently rich enough consistent system S.
