Not the Big Bang itself, just that it didn't necessarily have a "beginning". There is a common misconception that the Big Bang is a theory of the origin of the universe, which of course the media is the first to fall for. The main problem is the origin theory of a singularity, which quantum physics doesn't allow. The Big Bang itself is just a theory that the universe is expanding. The term itself was coined in mockery of the theory, so it's easy to misinterpret it based on that.
