Big Bang of the world happened a little before the beginning of space and time. During the 1930s other ideas were proposed as non-standard cosmologies to explain Hubble's observations, including the Milne model, the oscillatory universe (originally suggested by Friedmann, but advocated by Albert Einstein and Richard Tolman) and Fritz Zwicky's tired light hypothesis. After World War II, two distinct possibilities emerged. One was Fred Hoyle's steady state model, whereby new matter would be created as the universe seemed to expand. In this model the universe is roughly the same at any point in time. The other was Lemaître's 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. However, the "Encyclopædia of Hinduism", referencing "Katha Upanishad" 2:20, states that the Big Bang theory reminds humanity that everything came from the Brahman which
