A Humorous Study on the Annihilation of Sadako via Dual Television Systems: Sadako, the infamous entity from the Japanese horror film "The Ring", for cultural context

This study presents a conceptual and humorous model of the phenomenon known as ``Sadako''—an information-based entity that manifests in the real world via domestic television devices, as depicted in the Japanese horror film The Ring. In this model, Sadako is treated as an entity whose existence is realized through information, while the television functions as a boundary-mediating device. By coupling two televisions, the manifestation of Sadako can be conceptually annihilated, producing residual energy such as visual noise or light. This process is analogous to particle-antiparticle annihilation in quantum mechanics, maintaining the principle of information conservation. While the paper is intentionally humorous and hypothetical, it provides a playful yet coherent bridge between cultural horror phenomena and physics-based reasoning, suitable for educational and cultural discussions.
