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. Many of our observations in geology, such as plate tectonics, are not explained by a flat Earth.Ī spherical Earth is also a fundamental fact of navigation.Īnd of course we have many photographs of a spherical Earth from space.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. We now know that if the Earth were a flat disc instead of a sphere, gravity would also tend to pull people at the edges inwards towards the centre, not just down towards the surface-with all sorts of strange effects that we do not observe. The Greek mathematician Eratosthenes and the Roman-Greek-Egyptian mathematician Ptolemy were able to estimate the circumference of the Earth quite accurately, by measuring the angle of the sun in different places at the same time. Indeed people were able to demonstrate this in several ways more than two thousand years ago.Īristotle, for instance, observed that the Earth’s shadow on the moon during a lunar eclipse is always circular. There are many ways to prove that the Earth is spherical. You can help us take action – and get our regular free email
