Chaitin's Omega: Uncomputable Halting Probability Reveals Randomness in Arithmetic — E8 Intelligence Research

FINDING: Chaitin's Omega is an algorithmically random real number encoding the halting probability of a universal Turing machine, proving that some mathematical truths are unprovable and that randomness exists in arithmetic. MATH: - Ω = Σp halts 2-|p|, where |p| is the length of program p in bits. - Ω is normal in base 2 (each binary string of length n appears with asymptotic frequency 2⁻ⁿ). - Ω is uncomputable: no finite algorithm can output its binary expansion. - Ω is algorithmically random: its Kolmogorov complexity is maximal (≈ its length). - No finite axiomatic system can prove more than finitely many bits of Ω. CONNECTION: - The base-2 equidistribution of Ω's binary digits mirrors the uniform distribution of points on a circle (angle 2π × binary fraction). This ties to equidistribution on the 1-torus, a foundational case for homogeneous space dynamics. - The halting probability sum over programs of length |p| uses powers of 1/2, reminiscent of dyadic ra Author: Andrew Stewart Caldin, Independent Researcher, UK.
