Recently, some celebrities have put forward the (wrong) idea that the earth is flat. Not only does this make basically no sense, but there is also overwhelming evidence that the earth is round! Some of this evidence consists of pictures taken from space, individuals who have actually orbited the earth, and even some wealthy people who have taken flights around the world. Of course, some people need to see things in order to believe them, so is it impossible for these kinds of folks to actually get proof the earth is round?

Nope! As it turns out, there are plenty of ways to go about debunking flat-earth theories right here on our own planet. Some of these things you can do in your backyard, and some might need a little more cash. However, all these things can be done without going into space, and should help show nay-sayers once and for all that our planet is a globe.

Okay, proving the earth isn't flat might not be possible when it comes to some flat-earthers, but these are still some interesting things to try for yourself! After all, not everybody can be an astronaut.

You Can Watch A Ship Sail Away

Have you ever stood on the beach and watched the ships sail off into the distance, growing smaller and smaller? Believe it or not, just doing this can be used to show that the earth isn't flat. If the earth was indeed flat, the ship would get farther and farther away, until you couldn't see it anymore, and that would be all. But if you pay close attention, ships on the horizon don't do that. Instead, they appear to begin to sink below the waves, not only growing smaller, but also dipping down past where we can see. This happens because the earth is curved. Even though it's so slight that we can't easily perceive it with the naked eye while on the ground, the smoothness of the ocean allows you to see far enough that you can begin to observe ships moving over the curve away from you.

If the earth was flat, one would assume that it would be the same time everywhere. The sun above us might appear in a different area of the sky, but it would still be day for everyone until the sun went to the other side of the big flat-earth. But, as you might guess, that doesn't happen. This is because we have a little thing called time zones. These time zones mean that times are different in different parts of the country and different parts of the world. If you were to call up New York, and you were in San Francisco, they would tell you that they were three hours ahead of you in the day. Not only that, but if you did so in the late afternoon, you would hear that, in New York, the sun was already setting or getting ready to set!

This would not happen if the world was flat, because the sun would appear to set at basically the same time for all of us.

It's unlikely that you'll see as spectacular a solar eclipse as happened in 2017, but if you can figure out when the next lunar eclipse is, you can use it to prove that the earth is round. You see, a lunar eclipse happens when the earth is between the sun and the moon, and this then casts a shadow over the surface of the moon. That shape on the moon will then show you the shape of the earth, by it's shadow. If you check the shadow, it shows that the earth is round, like both the moon and the sun. Most flat-earthers still acknowledge that the earth spins, but if that was the case, an eclipse would sometimes look like a flat shadowy line, rather than a perfect circle. This means not only is the earth round, but it must be a sphere.

Who doesn't love a relaxing evening looking up at the stars? You can use this relaxing evening to also prove your point to non-believers that the earth is round.

Based on the time of night, you will look up and see several different constellations, or formations of stars, which could potentially still be true if the earth was flat and just spinning. However, the constellations you see also differ based on where you are in the world. If you live in the northern hemisphere and were to travel to the southern hemisphere, you would see constellations that you'd be genuinely unable to see back at home. Some constellations may also appear at different angles! The Big Dipper appears somewhat upside-down as you move from one hemisphere to the other. If the earth were flat, we'd all see the same constellations for the most part, and anyone who has traveled knows that's not how it works.
