You are far more familiar with YEC outlooks than I am, but I again emphasise that I am speaking about established (or Orthodox) theological implications from debates related to some branches of science. The example you give deals with Chemistry, and if some decide to take a different view, that has little to do with theology.
I am trying to be charitable; if someone has a view on the age of the earth, all of the chemistry in the world would not change that if such a person believed it was theologically correct. Orthodoxy as I understand it does not take such a view. The Creation days are not taken as scientific statements, and since they deal with God's creative acts through the power of His Word, all discussions would revolve about what we understand by the attribute of the Creative power of God. If you are interested, I can refer you to a recent discussion of a paper discussing an orthodox teaching about the energies of God as we would understand the creative act(s) in Academia.com. Be that as it may, this is the sort of discussion that I see as relevant.
I have stated numerous times, I am not YEC and I know very little about this subject, except that they believe in a 6,000 yr time for the creation - so there is little that I can add, and my interest in this area is about zero.
