Memes are able to contain facts

Okay, but that doesn't mean flat earth memes are right.

Lol, you're commenting on FE memes, I know you have no proof of a spinny-wawa-ball, so I'll just sit here and laugh at your sad, angry, frustrated disbelief. Earth is flat, deal with it. :D

My proof of a spinny-wawa-ball? It would be physically impossible for the earth to be flat. It's like saying that the train you are on isn't actually moving, instead, everything is moving around it.

Actually, Snipers use Earth's rotation to shoot.

pssst: no sniper "adjusts" for the unproven 'Earth's rotation' you speak of. The only 'rotation' that may be taken into account, is the possible 'spin' of the projectile (bullet) used. Hint: A rail gun does not adjust for any magical 'Earth's rotation' either.

What proof do you have?

"I" have a few, but ones YOU can find are the best. Try Sagnac, try Albert Michelson, Samuel Birley Rowbotham MD PhD (aka Parallax), Alex Gleason, try Electromagnetic realm, try Airy's failure, try Michelson and Gayle, try 'Rectangle', these will lead you to a flat , non-rotating Earth. And c'mon, you're on Imgflip.. go onto some FB FE forums, or maybe YT, this is a place for fun memes, why you buggin'?

You're the one who started it. Also, you have names, and appeals to authority; your evidence is presupposed.

Citing sources is a common practice to improve understanding and spread information without dealing with the "telephone effect" (how stories change as they are passed on). An invalid appeal to authority is saying that something is true because somebody else believes it. Stuff like "they taught me this in school" or "scientists say..." would classify as appeals to authority. Saying "Here are some people who do these tests, go look them up first-hand and see what they have to say" is a proper use of sources
