The gravitational Bohr radius (GBR) characterizes the size of a hypothetical ground state hydrogen atom wherein the binding interaction between its nucleus and its electronic structure is, When DSR’s scaling is used to calculate the GBR the result about 2pi times the conventional Bohr radius for the ground state of hydrogen. The same DSR scaling gives a Planck radius, mass and time, Robert L. Oldershaw Amherst College Amherst, MA 01002 USA ABSTRACT: The gravitational Bohr radius (GBR) characterizes the size of a hypothetical ground state hydrogen atom wherein the binding interaction between its nucleus and its electronic structure is purely gravitational. The conventional calculation of the GBR, based on, 6 BLACK-BODY RADIATION AND THE EARLY HISTORY OF THE UNIVERSE INTRODUCTION: In Lecture Notes 3 and 4 we discussed the dynamics of Newtonian cos. ology under the assumption that mass is conserved as the universe expands. In that case, since the physical volume., In this study, a radical hypothesis concerning the wave-particle duality exhibited by extremely small objects in nature is explored by developing a Planck lattice model of space–time that, The radical hypothesis concerning the physics of gravitational black-body radiation is placed on a more solid statistical mechanics foundation in this study..
