In 1948, Fred Hoyle set out his opposing Steady State theory in which the universe continually expanded but remained statistically unchanged as new matter is constantly created. These two theories were active contenders until the 1965 discovery, by Arno Penzias and Robert Wilson, of the cosmic microwave background radiation, a fact that is a straightforward prediction of the Big Bang theory, and one that the original Steady State theory could not account for. As a result, the Big Bang theory
Religious interpretations of the Big Bang theory and several complained that the beginning of time implied by the Big Bang imported religious concepts into physics; this objection was later repeated by supporters of the steady state theory, who rejected the implication that the universe had a beginning. The view from the Hindu "Puranas" is that of an eternal universe cosmology, in which time has no absolute beginning, but rather is infinite and cyclic, rather than a universe which originated from a Big Bang.
