There was a short-lived conspiracy theory in 2018 about the moon having 'moved' or the earth having 'moved' due to a video posted of the moon that seemed to show it being occluded by the earth horizontally instead of vertically. It was explained at the time by a number of people (I don't remember the explanation, but it had to do with where the moon & earth were in their orbits.) I wonder if she came across the old video?
