Can π Encode Anything? Unveiling Its Infinite Randomness and Information Power

π’s endless, non‑repeating decimal expansion behaves like a universal information reservoir: any finite digit sequence—birthdates, historic years, or arbitrary data—appears somewhere, and if the unproven normal‑number hypothesis holds, π could serve as an infinite random number generator for cryptography, art, and scientific modeling.
