For thousands of years, we've known that the Earth is in the shape of a sphere. It's not flat like they believed in the past. However, there are still some people who don't believe that this is true. You heard that right, despite all the evidence presented throughout the years, some people still don't believe that the Earth isn't flat.
If you happen to be one of these people, that's okay. It's quite easy to prove that the Earth isn't flat. All you have to do is perform some simple experiments. Sounds interesting? Read on to learn about these simple experiments. You can easily do these yourself. Maybe after these experiments, you'll start believing that our planet is actually spherical.
Head out and see it for yourself
For the first experiment, all you need to do is head outdoors and find a huge body of water. Once you've found a big enough body of water, try to search for a building or a ship that's far away. When you've spotted your target, move backward. The farther away you move, the more you'll notice that the building or the ship is descending into the horizon. If you're far enough, the objects may even look like they're below the horizon.
Here's another way to do it.
Go someplace where you can see the sunset. Ideally, you'd do this experiment at the beach. When you're in a good location, lay on your stomach. Make sure you're facing the sun and you can clearly see it when it sets. As you are laying there, you'll see how the sun gradually sets into the horizon.
When you cannot see the sun anymore, jump right up and you'll be able to see part of the sun again. As you're standing, you'll be able to see the sunset a second time.
It doesn't stop there!
You can get this same effect from an elevator which is going up. That is if the elevator is traveling fast enough. If you get the chance to ride such an elevator, go ahead and look at the scenery. The higher you go, the more you get to see. You will start to see more of the objects which are far in the horizon.
Go on a trip around the world
If you have the resources, you can book a flight to see the shape of the Earth for yourself. Take a tour around the world if you really need to prove to yourself that our planet really isn't flat. Just make sure that you're sitting on a window seat so you have a good view of what's out there. If you travel westward, you won't be able to see the sunrise, because it always rises on the east.
If you're planning to do the traveling experiment, try booking a night flight too. In doing this, you can look out the window and check out some of the different constellations. These are especially visible when the night is clear and free of clouds. If you're observant enough, you'll notice that the constellations vary. You'll see different ones depending on which side of the planet you're on. There are a lot of constellations in the sky. If you literally travel around the world, you might even get to see them all!
Stay home and stake some sticks on the ground
If you don't want to travel around the world, that's okay. You can still try and prove that the Earth isn't flat. Take a stick and plant it outside, on soft ground. You'll see that it will create a shadow (of course, it's better to do this when the sun is out). As time passes, you'll see that the shadow changes in position.
Plant another stick in the ground, far from the first. You'll notice that the shadow it creates is different. If the world were flat, these two sticks would create the same shadows. The shadows would have the same length, no matter how close or far apart you place the sticks. It's a fact that the Earth is round. And because of this, sticks which are placed in different locations will produce shadows of varying lengths.
Think about the time zones
This is another concrete way to prove that the Earth isn't flat. Think about it, when you live in New York and it's 12:00 pm, you'll see that the sun is right in the middle of the sky. At that same moment, most of the people in Beijing are sleeping because there, it's 12:00 midnight! New York and Beijing are at opposite sides of the Earth.
When the sun is shining on one side of the world, it means that the moon is reigning over the other side. This can't happen if the Earth is flat. In this case, then everyone in the world would experience the same time. When it's daytime in one country, it would be daytime in all others.
Different time zones exist because the world is round. What's more, it's constantly rotating on its own axis. This causes the change from day to night in all the parts of the world.
The Earth really isn't flat!
So are you convinced already? If you've done all these experiments and you're still not convinced, try searching for answers online. Search for real-life footage of our planet and you'll come up with a lot of videos to choose from. Then, all you have to do is sit back, relax, and enjoy the show. In those videos, you'll be able to see the beauty of our sphere-shaped Earth. If videos are not your thing, you can also look for different images of our Earth online. Trust us, there are hundreds of thousands of pictures for you to choose from.
All these are simple experiments. You can easily do them yourself if you really need to know if the Earth was flat or spherical, as most of humanity believes. Now you have different ideas to work with. All you need to do is choose the experiment which appeals to you the most and do it!
