👉 Platens is a mathematical concept in quantum mechanics that describes the distribution of energy within a system. It was introduced by Albert Einstein and Renato Janssen in 1947, but its precise definition has been debated among physicists since then. In general relativity, which describes gravity as a curvature of spacetime due to mass, platens can be thought of as the density or concentration of energy within a point-like object. However, the exact meaning and interpretation of platens in
