T.P. Walker, G. Steigman, D.N. Schramm, K.A. Olive, H.S. Kang, "Primordial nucleosynthesis redux," The Astrophysical Journal, 376:393, 1991. Terry Walker (Ohio State University, Columbus): "The standard model of the hot big bang assumes a homogeneous and isotropic universe with gravity described by general relativity and strong and electroweak interactions described by the standard model of particle physics. The hot big bang model makes two unavoidable predictions: (1) the presence of a low-energy background of relic photons, and (2) the production of primordial elements about one minute after the big bang (referred to as big bang or primordial nucleosynthesis). "The relic photons were first observed by Penzias and Wilson in 1965 and more recently by the COBE satellite (G.F. Smoot, et al., Astrophys. J., 371:1, 1991). "Although it is difficult to disentangle the primordial abundances of deuterium, 3He, 4He, and 7Li from observations made today, our paper shows that there is...
