Third: On a flat, non-rotating Earth, the water would go directly towards the center of the sink, the same everywhere. This would not happen on a flat planet either. If you look for information for Dubai, you will learn that in the Burj Khalifa building, which at 2,717 feet high is the tallest in the world, the sun sets three minutes later on the highest floor than on the lowest. Tables with sunset times are available online for almost every place in the world, so people can know exactly when to break the Ramadan fast. Islamic astronomers studied this very well. Moreover, and in relation to the previous point, the time at which the sun sets in each place also depends on the height from which you look at the horizon. If you think about it, this would not be the case on a flat Earth. Second: The times of sunrise and sunset are different in every part of the world. And vice versa: if you are in a port and you watch a ship arrive, first you will see the mast – the highest part of the ship – appear, then the sails, and finally the hull. This has been known since ancient times, and that is why lighthouses are placed on top of a tower so that they are visible from a greater distance. But that is not possible, due to the curvature of the surface of the Earth. With a powerful telescope you would see from New York to Madrid. If the Earth was flat, this would not be the case, as you would be able to see all the way to the end of the planet from any place without relief, even the sea.

There is much mathematical evidence that the Greeks calculated thanks to their knowledge of geometry and navigation – however, here we presented just five simple, easily verifiable arguments that explain why it is impossible for the Earth to be flat.įirst: Everybody knows that the higher we go, the further we can see. The Earth has been known to be round for more than 2,000 years, long before the satellites and the first circumnavigation of the world. But the debate is no longer scientific if we cannot trust the evidence offered by others imagine having an orange in front of your eyes while the flat-earthers tell you that what you see lacks credibility and insist that the orange is flat. However, many flat-earthers claim that all these images are fake.

There are about 5,000 satellites orbiting the Earth, taking daily photos that show the planet is round.

By now, humans have explored and measured the planet in a thousand different ways airplanes fly between all points of the map and the distances are well known. It is the flat-earthers the ones who would have to refute the roundness of the Earth, because the current evidence shows that the planet is round.
