Abstract: The presentation exploits several recent advances in understanding the nature of the Universe and its space medium. They include: (1) the DSSU theory of gravity, recently validated by successfully predicting observed patterns of galaxy clustering; (2) the new velocity-differential mechanism, a non-Doppler spectral shift; (3) the remarkably simplifying concept of particles, based on the photon, championed by physicist J. G. Williamson; (4) the unique subquantum medium founded in DSSU theory and the manner in which it conducts photons. Based on these concepts, which are essentially natural processes, it is clearly shown, with the aid of 15 figures, how the photon, the Universe’s fundamental energy particle, is causatively linked to gravity and how it plays a major role in gravitational collapse. The main focus is on the nature of end-stage collapse and the processes that maintain a stable state; the detailed discussion includes the calculations of the mass and radius of the final collapsed structure—the Superneutron Star.Abstract: The presentation exploits several recent advances in understanding the nature of the Universe and its space medium.
