  Physical cosmology tries to understand the Universe at large with its origin
and evolution. Observational and experimental situations in cosmology do not
allow us to proceed purely based on the empirical means. We examine in which
sense our cosmological assumptions in fact have shaped our current cosmological
worldview with consequent inevitable limits. Cosmology, as other branches of
science and knowledge, is a construct of human imagination reflecting the
popular belief system of the era. The question at issue deserves further
philosophic discussions. In Whitehead's words, "philosophy, in one of its
functions, is the critic of cosmologies". (Whitehead 1925)
