CMB. All matter radiates heat, regardless of its temperature. Astronomers can detect an extremely uniform radiation, called cosmic microwave background (CMB) radiation, coming from all directions. It appears to come from perfectly radiating matter whose temperature is 2.73 K—nearly absolute zero. Many incorrectly believe that the big bang theory predicted this radiation (h).
h. “The big bang made no quantitative prediction that the ‘background’ radiation would have a temperature of 3 degrees Kelvin (in fact its initial prediction [by George Gamow in 1946] was 30 degrees Kelvin); whereas Eddington in 1926 had already calculated that the ‘temperature of space’ produced by the radiation of starlight would be found to be 3 degrees Kelvin.” Tom Van Flandern, “Did the Universe Have a Beginning?” Meta Research Bulletin, Vol. 3, 15 September 1994, p. 33.
“Despite the widespread acceptance of the big bang theory as a working model for interpreting new findings, not a single important prediction of the theory has yet been confirmed, and substantial evidence has accumulated against it.” Ibid., p. 25.
“History also shows that some BB [big bang] cosmologists’ ‘predictions’ of MBR [microwave background radiation] temperature have been ‘adjusted’ after-the-fact to agree with observed temperatures.” William C. Mitchell, “Big Bang Theory Under Fire,” Physics Essays, Vol. 10, June 1997, pp. 370–379.
“What’s more, the big bang theory can boast of no quantitative predictions that have subsequently been validated by observation.” Eric J. Lerner et al., “Bucking the Big Bang,” New Scientist, Vol. 182, 22 May 2004, p. 20. [This blistering article critiquing the big bang theory was originally signed by 33 scientists from 10 countries.
