Why do people believe the Earth is flat?

So my friends and I were wondering. Do you really believe the earth is flat or are you just trolling?

Like, for realsies.

Thank you!

Yes, I got the order of places wrong, since the Arctic Sea is a long way from Antarctica - but also yes, they would eventually cross the Arctic Sea. It’s a globe, you know.

Excellent effort, but you missed a closing parenthesis.

I just watched that. Like the reviewer says in the link you just posted, I was actually impressed by how many of the flat earthers in the documentary had the critical thinking skills, technical ability and willingness to conduct controlled experiments to test their theories. Too bad they were unwilling to accept the results of their own tests.

If the more simple methods for observing the curvature of the earth don’t work for you, try explaining how a flat earth holds its shape.

You can run tests to determine the structural strength of the stuff the earth is made of, and you can determine the strength of gravity at earth’s surface. These facts are directly observable, you can do the tests yourself with a little knowledge. You can then do the calculations to see how strong a substance would have to be to be as big as the earth and to resist being pulled into a sphere by that much gravity.

You can walk and sail over the earth and measure it’s surface area if you don’t trust satellite measurements. If you don’t trust seismic echo imaging to tell you how deep the earth is and what’s down there, you can, of course, drill holes in it and see how far down it goes (and then explain the heat and layers of molten rock and metal on the “underside” of the earth). In any case, you can figure out how much mass it has from direct observations you can do yourself, given enough time, money and perseverance.

And then - well, nothing we know of on earth is sufficiently strong to resist that much gravity. Which is why the earth (and all the other planets and moons) are spherical: gravity pulls their matter into spheres.

If the earth really is flat, you have to prove (among many other impossible things) that it is made out of stuff that’s stronger than diamond, so it can hold its non-spherical shape against the force of gravity. Can you do that?

And can you explain how gravity pulls downward everywhere on earth, even though (as of course you know) on a flat earth as big as ours gravity would be stronger and stronger towards the edges, and would increasingly pull inwards towards the center of the disk (or square or whatever), not straight down? So things should fall at an angle towards the center of the disk (or whatever) on a flat earth, you couldn’t stand upright out towards the edge, and a ball on an even flat surface would roll towards the center of the disk (or whatever). Do you see these things in your “experiments”?

It’s fine to question everything, but if you don’t like other people’s answers, you have to prove that their answers are wrong. You guys can’t do that because you just don’t know much about the real world and how it works. Most of this stuff was figured out hundreds of years ago - you’re behind the times.

That guy pretty obviously doesn’t believe in gravity and it seems acceleration in general.

That sounds hard, can’t I just say your wrong enough times until public opinion changes and science gets defunded?

Edit: forgot the/s, I don’t want to gather supporters

I work in astronomy. From what I’ve seen, it would take a pretty small pin to poke that many holes in the top to make all the stars so we can breathe.

I feel bad for these flatearthers to have such a limited view of such an amazing universe.

It’s a real testimony to the power of the brain to resist cognitive dissonance. You can see it on their faces that it’s at times almost physically painful to keep ignoring the evidence, but some part of them NEEDS to so they keep rationalizing. When one believes in a conspiracy, all evidence is just evidence of the conspiracy.
