Implications of the statistical bootstrap model for cosmology and galaxy formation
The statistical bootstrap model suggests that the hadron level density is sigma (m) ~ Cm/sup 3./ exp(m/T/sub h/). With a spectrum of this type, massive hadron resonances will predominate in the early stages of the big bang, and the Universe will evolve out of equilibrium. The decay chains of these resonances may be so lengthy that the hadron era is prolonged far past its conventional end. The subsequent radiation era will be considerably foreshortened with the following major consequences. (i) Large density fluctuations are produced during the hadron era. The foreshortened radiation era is insufficiently lengthy for these fluctuations to be damped out. Thus, unlike conventional models, this model allows the causal development of galaxies from an initially homogeneous and isotropic state. (ii) During the hadron-dominated era a secondary gas of photons, leptons, and baryons builds up from the products of hadron decay. This secondary gas comes into equilibrium allowing the production of the present day 3 deg blackbody radiation despite the foreshortening of the radiation era. The buildup of the secondary gas involves the production of a considerable amount of entropy and thus helps in explaining the presently observed magnitude of the entropy density. (auth)
