Your wrong, You can't prove a hypothosis by assuming it to be true and
showing something.
By assuming that "H simulates the input correctly and correctly
determines that in input will not halt" is assuming that this CAN be
done, which it can't.
The fact that you can't recognize one of the fundamental fallicies of
classical logic shows that YOU are the one being amateurish.
That the statement is wrong can be done by a simple demonstration.
First Show that H(D,D) returns 0.
Then run D(D) and see that it halts.
SInce the DEFINITION of a Halt Decider is that its answer is supposed to
match the actual behavior of running the input, H is obviously wrong.
To claim that it correctly predicted what a correct simulation would do
is obviously wrong, as shown buy just running UTM(D,D) which will also halt.
To claim that it correctlr predecited whaat a correct simulation by H
would do is wrong, because we just showed what a "Correct Simulation"
does, and a "Correct Simulation by X" must match what a general "Correct
SImulation" does, or it isn't actualy a "Correct Simulation"
Thus the claim that H "Got the right asnwer" is invalidated. It is
proven that H never did a correct simulation to correctly show
something, since that isn't what is true.
Any claim that it is, is just a claim that a false statement must be
true "Because". All that it proves is that the logic used to say
"Because" must be wrong.
Please specify exactly which FACT I quoted you consider incorrect.
