No thank you. The nanodiamond problem will eventually work itself out with new atomic-probe tomography techniques and better sedimentary and meteoritic nanodiamond extraction techniques, and when and if Osiris-Rex ever returns some pristine carbonaceous materials that should provide some better selection of working materials as well. At best I am only willing to comment on new results, pro or con, when they arrive, here in these talk pages. The order of hypothesis rejection at this point needs to progress from 1) the sedimentary nanodiamonds do not exist, 2) these nanodiamonds are not real 3) the nanodiamonds are not impact nanodiamonds 4) they do not represent impact proxies and 5) there was not an impact at the Younger Dryas boundary. Many of the original points of the original hypothesis have already been refuted, and I have my preferred alternate already. Falsifying that has demonstrated to be a difficult and expensive long term task.
