oscillating Universe theory

views updated

oscillating Universe theory Variant of the ‘Big Bang’ theory in which it is suggested that the universe passes through successive cycles of expansion and contraction (or collapse). At the end of the collapse phase, with the universe packed into a small volume of great density, it is possible that a ‘bounce’ would occur. The universe would thus oscillate between Big Bang and ‘Big Crunch’ episodes, and so be infinite in age.
