Even a Kid Can Prove the Earth Is Round: Here’s How

Despite many scientific evidences, Flat Earth Society is convinced that we are living on a disc rather than a globe and now Mike Hughes, a believer of the flat earth theory, is determined to prove it by building his own rocket and seeing for himself that the Earth is flat.

For half a century now we’ve been able to view pictures of the Earth from space, but knowing how easily images can be changed together with the growth of internet conspiracy theories has fueled a resurgence of belief in a flat Earth.

Hughes’s idea is not that bad and maybe if more people followed his exam they could see for themselves the evidence. This way we might reverse this worrying trend.

Another good idea is if kids are given the chance to try out simple experiments on this matter in schools.

One of these experiments can be achieved simply by comparing the shadows of two sticks in different locations. When the sun is directly overhead in one place, the stick casts no shadow there, but at the same time in a city around 500 miles north the stick casts a shadow. If the Earth was indeed flat, both sticks would show the same results, because of their same angle position towards the sun.

It’s a simple experiment that dates back to ancient Greeks who used it for determining the Earth’s roundness. Even then, they concluded that the Earth was curved and tried to calculate its circumference, getting it to within 10% of the true value, which is not bad for around 250 B.C.

This aside, another piece of evidence that the Earth is not round is the difference between the night skies in the southern hemisphere and the skies in the northern one. The view from these two points is completely different, because our planet is pointing at a different direction.

There are many evidences, not including pictures, that show it’s very unlikely that the Earth is a flat disk.

Fake science

When done incorrectly, science experiments can appear to give the opposite results and then they quickly spread among people.

A perfect example is the Bedford Level experiment carried out back in 1838. It was used to prove that the Earth was flat and it involved placing a marker at a set height at either end of a canal about six miles long.

According to the experiment, if Earth was round one marker should appear lower than the other when viewed through a telescope at the same time.  The explanation was that the furthest marker should have fallen away with the curvature of the Earth, but the experiment reported that the markers are the same height, suggesting the Earth is actually flat. This theory is used by modern day Flat Earth theorists.

What’s wrong with this experiment is the fact that it doesn’t take into account the optical effect of the air over the intervening water, which bends the light and makes it look like the markers are the same height.

Some schools experiment by sending a camera up in a high-altitude balloon. Providing the means for people to test these theories themselves and to understand the results they get is better than the endless arguing on the internet.
