NASA / WMAP Science Team Alternatives to the Big Bang Theory . While the Big Bang theory is the most widely accepted model that explains the origins of the universe and is supported by all the observational evidence, there are other models that use the same evidence to tell a slightly different story.

The Big Bang theory describes the formation of our universe as a sudden, rapid expansion of matter and energy about 13.8 billion years ago. Evidence for the Big Bang includes cosmic background radiation and the redshift of most stars and galaxies, which shows that the universe is growing larger. However, scientists still don't know for certain what caused the Big Bang, because the laws of

The Big Bang Theory is one of the most plausible theories of how the universe has evolved, I cannot say there is evidence against it but there are many different theories to as how the universe was created. Physicists at Princeton University in the 1960's tried to resolve the question of another theory (steady state theory) against the big bang theory. They came to a conclusion that if the big

The Big Bang is the main theory that explains the origins of the universe - how everything was made, including the stars, the planets, and everything that lives on those planets, like us! It's widely believed by most astronomers, as it came about through scientific understanding of physics and chemistry. Even though it's a bit of a silly

The cyclic model of the universe he helped pioneer is just that: a theory that the universe forms itself again and again in cycles. Proponents of this model are asking us to rethink the Big Bang and the rapid inflation of the universe. They contend that doing so could fill in some of the biggest gaps in our common understanding of the way space
