We analyse aspects of the Big Bang program in modern cosmology, with special focus on the strategies employed by its adherents both in defending the theory against anomalous data and in dismissing rival accounts. We illustrate this by critically examining four aspects of Big Bang cosmology: the interpretation of the cosmic red-shift, the explanation of the cosmic background radiation, the inflation hypothesis and the search for dark matter. We conclude that the Big Bang's dominance of contemporary cosmology is not justified (...) by the degree of experimental support it receives relative to rival theories. (shrink)
