The Science of Biological and Atomic Continuity: A Biophysical Analysis of Post-Mortem Matter Transformation vs. Concepts of Reincarnation

The concept of reincarnation has historically been framed through metaphysical and theological perspectives. However, physical sciences, specifically thermodynamics, biochemistry, and ecology, provide a quantifiable, material framework for the post-mortem fate of organic entities. This paper investigates the law of conservation of mass and biogeochemical cycles to demonstrate how biological matter undergoes complete atomic recycling post-death. Rather than disappearing or undergoing mystical transmigrations, the chemical elements constituting living organisms are continuously integrated back into the Earth's atmosphere, hydrosphere, and lithosphere. These recycled elements subsequently become the building blocks for new plant, animal, and human life. Thus, this article presents a mechanistic explanation for biological continuity grounded in material chemistry.
