Sorry, no. I've not heard of them. If this is UFO kind of stuff, I tend to avoid that topic because it is almost exclusively in the realm of eyewitness testimony, which I don't trust.
It's one of 2 major causal hypotheses about how all those fires broke out at approximately the same time. It hypothesizes that remnants of Comet Biela set them. The other is that it was an entirely tropospheric fire storm. Otherwise there are those who say their synchronicity was neither as close nor as surprising as they might seem -- that conditions were just good for fires, and that there'd been a lot that summer, and chance takes care of their coincidence.
The Biela hypothesis is then taken as mutually reinforcing w the low-mass, high-energy hypothesis of the nature of some or all comets by devotees of electric universe thinking, because mass impacts don't usually favor starting fires. Accounts of the nature of the fire breakouts are taken as evidence of the fires' having been started by electric discharges.
What specific examples can you give?
From when I was teaching a general science course to undergrads (+ other general knowledge I had), there is just a relatively small amount of overlap between the data scaling astronomic distances at different scales by different means. Therefore there's a lot of bootstrapping going on that would give a great deal of leverage to a relatively small amount of new data, should it be produced, that would upset the scaling. The changes would propagate to produce a manifold difference in the estimates at the greatest distances. There's a lot of circularity in the determination that red shifts increase w distance, & that distances increase w red shifts. Using A as a proxy measure for B, using B as a proxy measure for A. There have been changes of orders of magnitude in the estimates of some astronomic distances, & I'm not confident that they're nailed down yet just because the past changes weren't recent.
I'm used to experimental methods of data gathering & hypothesis testing, so I tend to be skeptical of findings in non-experimental sciences.
