> Off topic: > > - Is the big bang theory the scientific consensus on the origin and evolution of the universe ? Yes, because this theory currently best describes our observations, but there are still many anomalies. Like dark matter / energy / quantum physics / axis of evil. > - What are the alternatives ? The big crunch, where the universe ultimately shrinks again. You also have a theory that it expands and shrinks and loops like that. You also have several string theories where they propose that the whole universe is a hologram projection of a higher dimension. But these theories are lacking certain important explanations of certain observations we have, that most people still keep the Big Bang Theory as the most accurate.
