Comment: the image is interesting but probably not a good aspect ratio for the main page
Overall: I see that this is your first submission. Very nice! And an interesting subject, too. I could stand to see a little more detail on the precise way it was disproven, though -- it requires quite a lot of pondering to infer the true mechanism of action from the reasoning given here. jp×g00:12, 25 October 2023 (UTC)[reply]
Thanks, User:JPxG. I did not want to add what seemed to me like original research, so I've tried to elaborate a little with some information from sources. Let me know if I can add more. Ideally this would be helped by a diagram but I don't have one at hand. Corundum Conundrum(CC)18:14, 27 October 2023 (UTC)[reply]
