Big Bang theory is the most accepted theory I know.But are there any mistakes in that theory and how much of these mistakes are present in that theory? Thanks.
<i>But are there any mistakes in that theory and how much of these mistakes are present in that theory?</i> If we knew about any outright mistakes, we'd be working very hard to correct them. In general terms, the big bang theory is accepted by virtually all astrophysicists. However, there are a number of unsolved issues to do with the theory, and a number of variant theories which incorporate many of the ideas of the big bang. We certainly have a lot left to find out about how our universe started, but in wide, sweeping terms the big bang is a very good explanation indeed.
