There is evidence to indicate the Big Bang may have resulted from another, earlier universe collapsing in on itself, rather than from expanding from a point on infinitely hot and dense material. Instead, the universe appears to be going through constant phases of expansion (as it is at present) and contraction in a never-ending cycle. This theory of universe formation, known as the Big Bounce, was first proposed almost a century ago.
universe is one of the assumptions of the cosmological principle. Answer: FALSE Page Ref: 26.1 2) The Big Bang was an expansion of matter into empty space Answer: FALSE 5) The universe has been expanding at the same rate since its formation.nswer: TRUE 11) Pair production is how a proton and electron are formed together from two photons, with neutrinos also given off. Answer: FALSE. 12) Before the Planck time of 10-43 seconds, the Big Bang must be treated as a singularity, with even general relativity yielding no information about it.
