Is Earth Actually Flat
Hey, Vsauce. Michael here.In 2003, researchers did the measurements and found that Kansas is in fact literallyflatter than a pancake. Of course, the Earth is not flat, the Earthis round. Otherwise travellers would be falling offthe edge all the time. Righté Wrong. If the Earth was not a ball shaped, but wasinstead a flat disk, like this plate, well with the weight, density and thickness, livingin 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 togetherthis great simulation. The person and buildings obviously aren'tto 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 atright 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 quot;don't fall off the edgequot; fear, on a flatworld because of gravity, the scary risk would
actually be falling away from the edge androlling all the way back to the centre. Once you stepped over the edge, instead offalling 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 morethan few hundred miles in diameter is round.
Or so we've been told.What if gravity isn't realé What if the Earth is, in fact, flat and sciencehas been wrong all alongé It's a misconception that Christopher Columbusdiscovered that the Earth is round. Virtually every scholar and major religionin 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 believedthe Earth was flat likely began in the modern era, as a sort of insult.Well, your people recently thought the Earth was flat, so why should we believe you nowéThe smear was repeated and published so often it became accepted as historical fact.quot;FlatEartherquot; became synonymous with quot;Antisciencequot;. It might seem flat over short distances, butover longer ones, well the Earth is pretty darn curvy. The Verrazanoâ€“Narrows Bridge, connecting Staten Island and Brooklyn, had to be designedwith Earth's roundness in mind.
