Cosmic Membrane Heart Hypothesis: A Self-Driven Cyclic Universe Powered by Meru Gravity — The Mythology of the Snack-Time Universe

A mythology born over snacks and juice. On the afternoon of May 19, 2026, in Fukui Prefecture, Japan, Yoshimitsu Katayama sat with snacks and juice and spoke the structure of the universe aloud. This paper is a verbatim translation of that conversation into physics. The Cosmic Membrane Heart Hypothesis proposes that the universe is bounded by an elastic spherical membrane (宇宙膜) that oscillates like a heartbeat — expanding in a Big Bang, contracting in a Big Crunch, then inverting its topology to eject the interior Genki Universe (元気宇宙) into the exterior. This ejected material accumulates as Mount Meru (須弥山) — a porous, cheese-like structure containing multiple universe-bearing cavities. Meru gravity drives the next contraction, creating a self-sustaining cosmic engine. Beyond Meru lies infinite pure space (無限空間) — ku (空), the container before Ma (間) is filled. The entire structure is a cosmic-scale Genki particle. Buddhist cosmology described this 2,500 years ago as the Three-Thousandfold World (三千大千世界). Physics is now catching up.
