If you watch a pendulum for long enough, you'll notice it starts to swing in a slightly different direction, which proves the Earth is rotating beneath your feet. This famous experiment was first demonstrated in 1851 by Leon Foucault and is now found in museums around the world. And even if it had a flat layer of liquid metal instead, the planet wouldn't rotate in a way that created a magnetic field. If the Earth was flat, it would have no core. Our planet has a magnetic field generated by the molten iron at the core of our planet. To explain seasons, Flat Earthers argue that the sun orbits in a circle above us.īut that doesn't explain time zones, though this is their attempt, which shows the sun as some kind of spotlight,Įveryone whose ever used a torch at night knows you can see its beam from the side - and that would apply to a flat Earth too. Take a trip to Antarcticaįlat Earthers argue that Antarctica is actually a massive ice wall around a flat Earth.īut, if that were true, the countless planes that fly over Antarctica would surely have just. To iron out this problem, Flat Earthers have concluded there is no such thing as gravity - you know, that force that pretty much holds the entire Universe together.īut if they were correct, you would not be able to weigh yourself at all. Gravity, which pulls everyone towards the centre of our planet's mass, means we weigh the same wherever we are in the world.īut a flat Earth would mean that those at the edge of the disk would be pulled sideways, while those at the centre would be pulled down. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA’s Terra satellite collected the land surface data over 16 days, while NOAA’s Geostationary Operational Environmental Satellite (GOES) produced a snapshot of the Earth’s clouds. But if the Earth was flat, their shadows would be the same.Įratosthenes, who conducted a version of this experiment, knew this 3,000 years ago 3. If you get two people at different distances from the equator, and they measure their shadows at the same time, their shadows will be different lengths. Look downĪn equally straightforward way to prove the Earth is not flat is to simply measure your shadow. One common example is the Bedford Level experiment, a form of which was first carried out in 1838 and used to prove the Earth was flat for over 30 years before an explanation was found. If the Earth was flat, everyone would be able to see the same constellations. Someone in Australia will see a different sky to someone in England at night - for example, you can't see Polaris, the North Star, from the southern hemisphere. When you look up at the night sky, you can only see certain constellations from certain points on Earth. So, with everyone staying inside over the course of the Covid-19 pandemic, we thought it was the perfect time to compile the ways you can prove that the Earth most definitely a globe. But a very, very small minority of us cling inexplicably to the idea of a flat Earth. Pretty much everyone knows the Earth is a globe.
