Non-thermal radiation processes

With my collaborators, Fred Hoyle and Jayant Narlikar, I am working on the nature of
quasi-stellar objects, the origin of the redshifts in these objects, and on Quasi-Steady
State Cosmology, an alternative to the Big Bang theory.

The Quasi-Steady State Cosmology

The Quasi-Steady State Cosmology is an oscillatory, general-relativistic cosmology in which matter is created in "mini-big bangs" of about 1016 M, occurring at intervals of ~ H0-1. In this model, 4He is produced by nucleosynthesis in stars. It is then thermalized by dust grains at epochs near oscillatory minimum to produce the observed cosmic microwave background radiation (CMB). The energy released in the synthesis of cosmic 4He from hydrogen is nearly equal to the energy contained in the CMB. This result strongly suggests that the 4He was produced by hydrogen burning in stars and not in the early stages of a big bang. In addition, we have shown that there are good arguments for believing that the other light isotopes, D, 3He, 6Li, 7Li, 9Be, 10B, and 11B, were also synthesized in processes within stars. By combining these results with the earlier, much more detailed work of Burbidge et al. and of Cameron, we conclude that all of the chemical elements were synthesized from hydrogen in stars over a time of about 1011 yr.

This cosmology is described in our article in the April 1999 Physics Today and in several of the publications listed below.
