High-energy Astrophysics and a Possible Sub-nuclear Energy Source

Abstract

ENERGY is always released when, due to the natural interactions, more bound states are formed from less bound states. This happens, for example, during the gravitational contraction of a given mass, the energy release being related to the long-range gravitational attraction and to the macroscopic properties of the matter. This is also true of nuclear reactions, when the process is connected with the nuclear structure of the matter and the short-range nuclear interactions.
