Following this question on the Entropy at the Big Bang where I asked:
Since Entropy always increases (in general); its expected that the entropy at the beginning of the universe should be the lowest possible.
One answer to this by Chris White suggested that:
This is a logical fallacy. From the premiss "entropy always increases," we can derive the conclusion "the entropy at the beginning of the universe was lower than it is now." We cannot from this one premiss say anything about the absolute entropy back then. In particular, there is no reason it need be close to zero or a minimal value in any sense. Is simply cannot be maximal.
But this seems to be, to some extent invalidated by another answer where its stated that
The quark-gluon plasma has been shown to be a [minimal entropy fluid] .
This plasma existed a few milli-seconds after the Big-Bang; it seems rather incredible that entropy can be at a minimum slightly after the Big Bang, but not at it (if or when this can be given a meaning).
This leads to a question: If the Quark-Gluon plasma is as far theoretically we can go far back, and its entropy is at a minimum; then can we not set it as zero - thus making entropy absolute, in the same way that temperture is absolute.
