The cosmic star formation rate is seen to peak about a redshift of 3, about 11,500,000,000 years ago, when the universe was about 2,200,000,000 years old. It has fallen off by about a factor of 10 since then. See, for instance, Hopkins & Beacom, 2006. |
The conclusion that all observational evidence is consistent with the standard model framework is simply not true.
One of the outstanding features of the ‘early’ universe is that galaxies out to redshift 7 appear to have normal stellar populations (Richard S. Ellis, Caltech, 2004).
Using data obtained with the Frederick C. Gillett Gemini North Telescope on Mauna Kea, Gemini Deep Deep Survey took the deepest spectra ever of very distant galaxies. The galaxy populations encountered look identical to local groups, with astoundingly no sign of evolution during this important era that was believed to be one of most significant change.
"It is quite obvious from the Gemini spectra that these are indeed very mature galaxies, and we are not seeing the effects of obscuring dust. Obviously there are some major aspects about the early lives of galaxies that we just don’t understand.” Said Patrick McCarthy (Observatories of the Carnegie Institution).
“Studying the chemical composition of the interstellar gas, we discovered that the galaxies in our survey are more metal-rich than expected." Sandra Savaglio (Johns Hopkins University).
Hold on, there’s more: Isobel Hook (see Hook et al, c2004), head of the UK Gemini Support Group, (Oxford University) is part of the Gemini Deep Deep Survey (GDDS) team whose objective is to capture the faintest galactic light ever detected. Three hundred galaxies were scrutinized. “These highly developed galaxies, whose star-forming youth is in fact long gone, just shouldn’t be there, but are," said Co-Principal Investigator Karl Glazebrook (Johns Hopkins University).
Others too have found that distant red galaxies in the Hubble Ultra Deep Field (Toft et al 2005) present morphological properties that suggest “complex stellar populations, consisting of both evolved populations that dominate the mass and the restframe optical light, and younger populations, which show up as patches of star formation in the restframe UV light; in many ways resembling the properties of normal local galaxies."
The supposition that the morphology of galaxies in the Hubble Deep Fields is very different in the past than in the present is not a confirmed observational fact, when redshift and surface brightness are taken into account (Buta & Block 2001, Thompson, R.I, 2000, Ellis 1997, Takamiya 1999).
