I have some questions concerning the Standard Hot Big Bang model versus the Inflationary model.

I've read that the Standard model cannot solve the Horizon and Flatness problems but Inflationary cosmology can.

Firstly, is this so?

Any replies that are pitched at my basic level of understanding would be appreciated.

Secondly, it's my understanding that within the discipline of science a model or theory of greater explanatory power will supersede one of lesser power. Am I on the right track here?

Thirdly, I've read that in the Standard model there was no viable mechanism to solve the Horizon and Flatness problems. Is that so?

Lastly, assuming that the Standard model

*does*suffer from these weaknesses and the Inflationary model

*doesn't*is there any viable case for continued support of the Standard model over the Inflationary one?

Thank you,

Cerenkov.
