Fisking a flat-earth meme

 I found this meme in two groups yesterday, by the same poster.  I didn't check to see if he posted it in more places.  Below is my response.


How to tell someone else has learned all their science from YouTube (even though that if they looked, they would also find videos explaining this there, too.

* They can't predict what the effects of Earth's rotation would be but they repeat "1000 MPH" instead of plugging that into the the formula for centripetal acceleration together with the radius of the Earth.

* They refuse not only to believe other's measurements of curvature, but refuse to try to measure it themselves. They will probably use an incorrect formula for how far an observer can see which does not take into account the height of the observer or observee. They may ignore that they cannot see the bottom of the observee. Or claim that a telescope can "bring it back".

* They use "perspective" as an all-purpose answer without knowing what it means.

* They don't understand aviation

* They don't understand how the distance to the Sun was measured. They certainly haven't tried to do it themselves. When asked how far it is, they will either refuse to commit to anything other than "local". They may show photos of crepuscular rays through clouds or ones that they claim show the Sun lower than clouds.

* They dismiss all photos from space are fake, whether from NASA or another source without explanation. They don't understand photography.

* The proofs have gone over their head, instead of asking for help to understand them (which they don't want, because their minds are already made up) they just say "no proof"

And one more:

* They respond with claims that anyone who disagrees with them is "indoctrinated", insults, meme dumps, laugh emojis, or simply don't respond.
