Did the Universe have zero entropy when it first began?

One of the most inviolable laws in the Universe is the <a href="https://en.wikipedia.org/wiki/Second_law_of_thermodynamics" rel="noopener ugc nofollow" target="_blank">second law of thermodynamics</a>. It tell us that, in any physical system, where <a href="https://bigthink.com/starts-with-a-bang/entropy-closed-system-increase/" rel="noopener ugc nofollow" target="_blank">nothing (no particles and no energy) is exchanged with the outside environment</a>, entropy always increases. This is true not only of a closed and isolated system within our Universe, but of the entire Universe itself. If you look at the Universe today and compare it to the Universe at any earlier point in time, you’ll find that the entropy has always risen and continues to rise, with no exceptions, throughout all of our cosmic history. But what if we go all the way back to the earliest times of all: to the very first moments of the Big Bang? What about even earlier: to <a href="https://bigthink.com/starts-with-a-bang/cosmic-inflation-past-hypothesis/" rel="noopener ugc nofollow" target="_blank">the epoch of cosmic inflation</a> that preceded and set up the hot Big Bang? If entropy has always increased, does that mean that the entropy of the Universe started from a value of zero at some initial time, and a state of what we might think of as “maximal organization” at some point? <a href="https://medium.com/starts-with-a-bang/did-the-universe-have-zero-entropy-when-it-first-began-2fe43224de46">Visit Now</a>
