It posits that the universe was very dense and hot, with a certain structure to its flictuations. That is sufficient to explain the creation of matter and subsequent evolution. Anything beyond that is speculation. A nontrivial mechanism such as inflation is required in the early phase in order to explain flatness homogeneity and the roughly scale invariant perturbation spectrum. What happens before inflation and how it gets started, is even more speculative.
This is the thinking today? Could you provide a link or two to articles that discuss this change of thought? Apparently, I have some catching up to do.
Thanks!
