I was hoping for someone who actually believes this but I'll take what I can get.

1. you don't weigh less at the horizon.

While flat-earthers will contend that there is no such thing as gravity, this force unites the entire universe. It"s everything from what makes the numbers jump on a bathroom scale to the reason why planets and stars form. It uniformly pulls everyone on the surface of Earth toward our planet"s center of mass (roughly the exact center). That"s why you"ll weigh the same in Los Angeles as you will in Jakarta.

If the Earth was flat, gravity would no longer pull everyone the same way. If the flat Earth would be something like a disk, those at the edge of the disk would be pulled relatively sideways, while those at the center of the plate would be pulled straight down. The difference would change your weight enough to confuse a bathroom scale. Considering that humans have been to every landmass on Earth without celebrating sudden lightness, we can rule out a flat planet.

Where is the edge of the world according to flat-earthers? The answer changes, but it usually involves some impenetrable barrier at said edge that prevents people from going past or falling off. Global conspiracies apparently prevent people from investigating these boundaries. But in reality, humans have circumnavigated the planet in planes and ships, and no one has fallen into space. Rather, when ships traveling large distances on the ocean do appear and disappear on the horizon, they do so either mast or hull-first, respectively. If the Earth was flat, and you had the right optics, you could watch a ship sail from New York to Africa without losing sight of it. You can"t because the curve of the Earth makes the ship dip below the horizon.

YOU DON"T ALWAYS SEE THE SAME CONSTELLATIONS
Hit up a friend in Australia and ask them what constellations they can see at night. Now tell them which ones pepper your patch of darkness. They won"t be the same. Because the Earth is a shape other than a flat disk, when looking into the night sky the Earth itself can block your view.

If the flat Earth theory were true, everyone should be able to see the same constellations all the time, as if we all were staring up from the same section of summer grass. Here"s one you can try at home. If the Earth were flat, you could drive two sticks into the ground at any place on Earth, and the shadows those sticks would make would be the same length. (Because the Sun is so far away from Earth, its incoming rays can be considered parallel).

Place a stick in the ground on a sunny day, then measure the length of the shadow. At the same time, call a friend who is at least a few miles away from you and tell them to do the same. The lengths you measure will be different! The curvature of a spherical Earth means that sun rays will hit each stick differently if they are far enough apart.

Measuring shadows like that is how Greek astronomer Eratosthenes very nearly calculated the exact circumference of the Earth in"250 B.C. Yep. We"ve been certain the Earth is round since maybe 500 B.C., or 2500 years before a rapper dropped a flat Earth diss track.

TIMEZONES EXIST
To make the seasons work with a flat Earth, advocates claim that the Sun orbits in a circle above our disk, like a tetherball on an invisible string. But timezones exist. Try calling someone in China right now and convincing them that you are experiencing the same time of day (and then apologize).

A flat Earth can"t account for how some parts of the planet are provably in darkness while other parts are bathed in light.

THE REST OF THE SOLAR SYSTEM
Like how we"ve seen the Earth from many angles and found it round, we"ve sent cameras to the rest of the planets in our solar system and snapped photos of them from many angles too. They all appear to be spheres. That makes sense if gravity is the main force in the universe pulling cosmic gas and dust and rock together to form planets.

The chances that the Earth is the only planet in the solar system that is non-spherical, yet subject to the same forces as other planets, are zero.

ECLIPSES SHOW YOU EARTH"S SHAPE
Have you ever seen a lunar eclipse? It"s when the Earth passes in between the Sun and our moon and casts a shadow over the lunar surface. If you look closely, you can pick out a slight curvature.

Curvature is possible with a flat disk, but even flat-earthers admit that the Earth spins. If the Earth were flat, there would be some people that occasionally see a straight line projected on the moon (the edge of a disk). That hasn"t happened since humans looked up, so a sphere is the logical shape to assume.

@tanner_1230 there are more flat earthers out there than you think.

Would like to make something very clear, I do not actually support the flat-earth!!! I'm just doing this debate for fun.
