Proofs That The Earth Is Spherical
Humans have known for millennia that the Earth is not flat. I want to show you more ways to prove that the world is round. I have few ideas how to do this, but I got an interesting push when the evil astronomer Phil Plait wrote about the Flat Earth Society. He says that bothering to deny the Flat Earth Society is pointless – I tend to agree. But the history of our species’ intellectual pursuits is important and interesting. You don’t have to condemn all science and knowledge and believe in conspiracy theories to enjoy the historical facts of human space exploration.
The Bizarre Tale Of The Flat Earth Convention That Fell Apart
Now that humanity is positively convinced that the moon is not a piece of cheese or a god of fun, the phenomena that accompany it (from monthly cycles to lunar eclipses) are well explained. However, A bit of a mystery to the ancient Greeks, and in their search for information, humans made insightful observations that helped us discover the shape of our planet.
Aristotle (who made some observations on the spherical nature of the Earth) noticed the silhouette of a satellite during a lunar eclipse (where the Earth’s orbit is placed directly between the Sun and the Moon, creating a shadow). The face is round. This shadow is a planet, It is the perfect proof for around the world.
Since the Earth rotates (see Fouac’s pendulum experiment if you doubt it), its constant oval shadow at each eclipse proves that the Earth is not round, but spherical. Definitely not flat.
If you’ve been walking near a harbor or along a beach recently and staring blankly at the horizon; You may notice a very interesting phenomenon: approaching ships do not “pop” on the horizon as they should. If the world were flat, it would appear to come from under the sea.

But as you say, Ships sink as they approach us and never rise again (except for Pirates of the Caribbean, which we think is a fake movie series). The reason ships look like they “rise from the waves” is because the world is not flat.
Visualize an ant walking across an orange screen into your vision. If you look at the orange “head” you will see an ant slowly rising from the “horizon” due to the curvature of the orange. If you were to do this experiment with an ant approaching from a distance, Instead, the reverse will happen: the ant will slowly “realize” (depending on your vision).
This observation was originally made by Aristotle (384-322 BC), who declared that the Earth is round, judging by the different constellations we see as it moves away from the equator.
After returning from a trip to Egypt, Aristotle said, “In Egypt and Cyprus, in the northern regions, unseen stars are seen.” This phenomenon can only be explained if people look at the stars from a round surface. Aristotle said that the sphere of the earth is not a large size; Otherwise, the impact of a small change in location may not be noticed quickly enough, he said. .
Planet Earth Facts And Information
The further stars from the equator toward the horizon are the “known” constellations that will be replaced by different stars. This wouldn’t happen if the world was flat.
If you stick the stick to the ground (sticky), a shadow will appear. The shadow moves with time (this is the principle of ancient shadow clocks). If the world were flat, two sticks in different places would cast the same shadow.
Eratosthenes (276-194 BC) accurately calculated the circumference of the Earth using this principle. Watch my test video on Eratosthenes and the Circle of the Earth to see a demonstration of this.
You stand on a flat plateau and look forward to the horizon. After straining your eyes, get out your favorite binoculars and look through them as far as your eyes can see (with the help of the lenses).

Then climb the nearest tree – the higher the Be careful not to drop the binoculars and break their lenses. Then look again, Keep your eyes peeled and look at the telescopes on the horizon.
The higher you are The more you can see. Usually we attribute it to earthly obstacles such as houses or other trees blocking our view on the ground, and when we go up we can see clearly, but this is not the real reason. Even if you are standing on a clear plateau with no obstructions between you and the horizon, you can be seen from a height higher than the ground.
This phenomenon is caused by the curvature of the Earth and would not occur if the Earth were flat.
If you have ever traveled outside the country; You may notice two interesting things about the plane and the Earth, especially on long trips.
How Ridiculous Ideas Gain Traction. We’re Looking At You, Flat Earth
It is true that Earth is different from other planets. after all, We have life; We haven’t found any other planets yet. However, All planets have some characteristics in common; Each planet behaves in a certain way or has certain characteristics. Especially if these planets are in different places or were created under different conditions. The planet itself.
In other words, If many planets created in different places have the same property under different conditions, it is likely that our planet will also have the same property. All of our observations show that the other planets are spheres (it’s also clear that they have that shape because we know how they were formed). Unless we have good reason to think otherwise (and we don’t), our planet is the same.
In 1610, Galileo Galilei saw Jupiter’s moons revolving around it. He stated that it was a very difficult description (observation) for the Church to accept as small planets orbiting a large planet. This observation also showed that all the planets (Jupiter, Neptune, and later Venus) were circular and all revolved around the Sun.
A flat planet (ours or any other) would be a surprising observation that would contradict everything we know about planetary structure and behavior. This includes everything we know about planetary formation, but also about star formation (our Sun would be completely different to fit the plate theory) and what we know about speed and motion in space (e.g. planetary orbits and the effects of gravity). In short, we have no doubt that our planet is merely spherical. We know.
What Shape Is The Earth
It’s 12:00 noon in New York City as I write these words. The sun is in the middle of the sky (though it’s hard to see because of the current cloud cover). It’s 12:00 midnight in Beijing and the sun is nowhere to be found. The time is 1:30. Australia Over 13 hours early in Adelaide. The sunset had long passed there, so the sun would soon rise again to start a new day.
This can only be explained if the Earth is round and rotating on its axis. At one point, when the sun shines on one side of the Earth, the other side is dark and vice versa. It allows you to set time differences and time zones, especially times greater than 12 hours.
Timetables; Another thing about the sun and the earth: the sun is a “beam” (directed high so that it shines only in one spot), and if the earth were flat, we would see the sun even if we couldn’t see it. . . It makes us shine (as you can see in the picture below). Similarly, You—the crowd—are sitting in the dark, but you can see them coming from the lights on the stage. The only way to create two clearly separated timelines is if one world is completely dark and the other is completely light.
Here’s the interesting thing about mass: things attract. The force of attraction (attraction) between two objects depends on their mass and mass.
