Hey, Vsauce. Michael here. In 2003, researchers did the measurements and found that Kansas is in fact literally flatter than a pancake. Of course, the Earth is not flat, the Earth is round. Otherwise travellers would be falling off the edge all the time. Right? Wrong. If the Earth was not a ball shaped, but was instead a flat disk, like this plate, well with the weight, density and thickness, living in the middle could feel pretty normal. But as you move toward the edge, gravity on a disk Earth would slightly skew, pushing at a greater and greater angle back toward the centre. My friend Nick from 'yeti dynamics' put together this great simulation. The person and buildings obviously aren't to scale but check out how such increasingly diagonal gravity would work. Although this is a flat disk, it would feel to a runner headed toward the edge, like they were fighting to climb up a steeper and steeper hill. The building foundations behind the runner reflect how you would have to build structures, closer and closer to the edge, so that people living in them always felt like down was at right angles to the floor - the way we feel it on our big, round Earth. As you approach the edge, things would get scary. Remember, this is a flat Earth, but it would feel like a sheer drop off. What's really cool is that contrary to the "don't fall off the edge" fear, on a flat world because of gravity, the scary risk would actually be falling away from the edge and rolling all the way back to the centre. Once you stepped over the edge, instead of falling off into space, you'd be able to relax. It would be a nice level place. This model, of course, neglects the fact that such a planet shape would be impossible. Anything as massive as the Earth, shaped like a flat disc, would, under its own gravity, naturally collapse back into a ball. This is why in outer space everything more than few hundred miles in diameter is round. Or so we've been told. What if gravity isn't real? What if the Earth is, in fact, flat and science has been wrong all along? It's a misconception that Christopher Columbus discovered that the Earth is round. Virtually every scholar and major religion in the West accepted Earth's rotundity, since at least the time of the Ancient Greeks, who, for instance, had noticed that boats disappear bottom first when sailing away. And, as you walk north and south, stars pop in and out of the view. The misconception that only a few hundred years ago lots and lots of people bel
