i'd argue, no. there was a singularity. infinite density in an infinitely small volume. inf/(1/inf) does not = 0.
therefore, it was LOW entropy, but not zero.
i think people are making some entropy mistakes somewhere b/c as i understand it (please correct me if i'm wrong), every moment in time that has passed since the big bang, there are more ways to order the universe as there were in the previous moment.
so S = KlogW necessarily increases every moment since the singularity, including what started inflation and during inflation.
inflation supposedly started due to quantum fluctuations in the "skin" of the universe (i.e. imagine a balloon being blown up, small distances/differences become larger as an easier way to think about it), thus there are some small discrepancies in the CMB while it remains globally homogeneous. prior to the start of inflation, there were still fewer and fewer ways to order the universe.
at no point in my understanding did we go from a high entropy state to a low entropy state.
second, if we did assume at first there was literally nothing, that still goes from S = 0, to S>0 from one moment before the existence of the universe to the moment the universe began.
so can we clarify where the entropy issue with the origin of the universe came from? to me it seems that we've always gone from S->S+x, where x>0
