Generally about proposed solutions

[ReneZ]

For example, if I said "the earths flat" I might ask for a photo from space showing it is not.

This is not a bad analogy, because such obvious and straighforward evidence-based arguments still fail to convince flat-Earthers.
I am not aware of the latest status there, but in the past, the counter-argument would be that the curvature in the photo was introduced by the effect of the curved lense  (for example).
