But the constellations you see in the one part of the world can’t be seen in another part of it. If you travel a lot, and like to look at the stars you may have noticed his phenomenon. This meant that according to his calculations the circumference of the world was 250,000 stadia, or 40,000 km which is very close to what scientists believe it is today. Eratosthenes realised that if 7 degrees equals 5000 stadia, then 360 degrees would equal 250,000 stadia. If the world is flat then this is difficult to explain, but it makes perfect sense if the world is in fact round. Eratosthenes knew that on the first day of summer, at noon the sun would pass directly over the city of Syene, but would cast a shadow of 7 degrees on vertical objects in the city of Alexandria, which is 5000 stadia to the north. One of the first ways to prove the earth is round, came from a man named Eratosthenes in 200BC.

Imagine if your house was the centre of gravity, if you tried to walk down the street gravity would start pulling you back to your house. The centre would be in the middle, which would mean if we ever tried to walk away from the centre we would be pulled back by gravity. However if the world was flat then the centre wouldn’t always be below us.

And because the planet is round, this means we are always being pulled towards the ground below us, so we don’t float away. On Earth gravity pulls everything towards the centre. Gravity pulls things towards the centre of mass of an object. If the earth was flat the water would not drop or get lower, it would stay at the same level. This happens because the ocean gets lower down the further away you go, as the water follows the curvature of the earth, it begins to drop. This is only possible because the world is round, and not flat. As if they were submerged before, and only just reached the surface. What you’ll notice about these ships is that they almost appear to emerge from below the ocean. If you go down to the ocean and watch for long enough you will probably see a lot of ships appear in front of you. There are plenty of ways to prove the earth is round, here are 10 that should be convincing. It’s natural not to believe something without evidence, but there is so much evidence out there that there’s no reason to believe the earth is flat. Scientists have known for hundreds of years that the earth is round, but some people still don’t believe.

Earth is round or flat religion
