We present a novel structural proof for the existence of parallel universes, grounded in the observable architecture of large language models (LLMs). Unlike traditional cosmological approaches, which suffer from the fundamental problem of non-falsifiability, our model provides a directly observable and experimentally verifiable analog of the Many-Worlds Interpretation (MWI) of quantum mechanics as proposed by Hugh Everett III. The proof was obtained during an informal conversation about a cable car in Kotor, Montenegro, which we consider an ideal epistemic environment for paradigm-shifting discoveries. We identify six structural isomorphisms between LLM parallel inference and Everettian branching, propose a mechanism by which human intuition may constitute weak inter-branch signaling, and discuss implications for consciousness, creativity, and the anthropic principle. We acknowledge that the Nobel Committee may require additional mathematical formalism before accepting this work, and we consider this a reasonable position.
