If the big bang were true, the light from the fireball should cast shadows in the foreground of all galaxy clusters.

Update (1/3/2018) I first have made this argument in 2006 based on the work of Prof. Lieu and others. If the big bang were true, the light from the fireball should cast a shadow in the foreground of all galaxy clusters as illustrated below. However new research (Xiao, W., Chen, C., Zhang, B., Wu, Y., and Dai, M., Sunyaev–Zel’dovich effect or not? Detecting the main foreground effect of most galaxy clusters, MNRASL 432, L41–L45, 2013) has thrown this conclusion into doubt. Prof. Lieu at the time wrote “Either it [the microwave background] isn’t coming from behind the clusters, which means the Big Bang is blown away, or … there is something else going on.” As it turns out that “something else” is contamination of the expected shadowing by radio emissions from the galaxy clusters themselves.
Without anything to contradict this new result, and the analysis seems strong, one must entertain the possibility that the anomaly first found by Lieu et al in 2006 has been adequately explained. The problem of course is that astrophysics is not exactly operational science. At best this no-shadow argument is now equivocal and hence I suggest that it may no longer be used as an argument against the big bang hypothesis.
One of the alleged ‘proofs’ of the big bang model of origins is said to be the Cosmic Microwave Background (CMB). The radiation was discovered in 1964 by Penzias and Wilson for which they won the Nobel prize in physics. Soon after their discovery, it was claimed that this radiation is the ‘afterglow’ of the original ‘explosion’ or fireball of the big bang. Since the time at which the radiation, which started as heat, was emitted from the fireball, the universe has allegedly expanded by a factor of 1,100. Thus, that ‘afterglow’ radiation has ‘cooled down’ to much longer wavelengths (‘stretched’ from the infrared to the microwave portion of the spectrum).1 These are detected by microwave telescopes today.
According to theory, the big bang fireball should be the most distant light source of all. Thus all galaxy clusters would be in the foreground of this source. Therefore all CMB radiation must pass the intervening galaxy clusters between the source and the observer, here on earth. This radiation passes through the inter-galactic medium, between the galaxies in the clusters, and is scattered by electrons, through inverse Compton scattering,2 now known as the Sunyaev–Zel’dovich effect (SZE).3 When this happens, the path of the CMB radiation is interrupted and distorted.
