The Formal Theorem

No Halt-Checker exists

Analytical Intuition.

The Halting Problem is the Limit of Logic. No program can look at another and tell if it will stop or run forever. Turing used self-reference to create a logical loop, defining the edge of the computable world.
CAUTION

Institutional Warning.

The CS version of 'This sentence is a lie.' If the checker says it halts, it loops; if it loops, it halts. Logic breaks the machine.
