Instead of the Big Bang, some physicists have
suggested tha t our universe may have come from a big bounce following another
universe contracting – but quantum theory could rule this out.
Did our solar system had a beginning that was before God
created it at the beginning, Some evolutionists think so, but others are not
so sure.
Could our universe be expanding and shrinking back into a tiny point, reliving a kind of
big bang over and over again? Probably not, according to a mathematical
analysis that argues that the laws of physic forbid such a cyclic universe.
A key moment in the life of a cyclic universe is the big bounce, an alternative to the big bang as the beginning of the known universe. The big bang starts with a singularity – matter and energy packed into a point so dense that gravity becomes strong enough to elude the laws of physics as we understand them – followed by an endless outwards expansion. But if the universe began with a big bounce, we could look beyond what we think of as the beginning and see another universe contracting to form an incredibly dense point, but not necessarily a singularity, before bouncing back out into the expanding universe we live in today.
