[snip] I read something about this very theory at least a month ago. Was it something you posted or something on Phys.org I read? [/snip]

There’s a post, somewhere on FR, that I read literally in the past couple of days, before I saw this “red crucifix” thing, someone could recall learning (years ago) about some kind of celestial phenom (comet, meteor/ite, supernova) that appeared to lead to the Black Death, I think it was. :’) Wish I knew where. Someone asked me in open thread if I knew what it was.
