What if the Earth was Flat?

You can see the shadow of the earth cutting across the face of the moon, and the shape of the shadow is bent because the earth is round. Because the Earth is orbiting (see Foucault's pendulum check for complete evidence if you doubt), the harmonious circular shadow it produces during all lunar eclipses proves that the earth is not just round, but round - completely.

Although the Earth appears round, it is close to the ellipsoid. We also know these days that the Earth is not a globe - it is a slightly ellipsoid (ovoid), mainly because of its orbit.

But Ms. Jayasuriya added that her appearance is the result of exposing a 3D space in a 2D plane. A flat earth model is an ancient concept of land in the form of a flat or disk.

As scholar and author Stephen Jay Gould once wrote, many people, including the Spaniards and Christopher Columbus, believed that the Earth was flat, a theory that was strongly influenced by 19th-century writers such as Washington Irving, Jean, and others. Contrary to popular belief, there is a belief that many serious, educated people once believed that the flat earth's theory was wrong. Cartographer Chandra Jayasuriya of the University of Melbourne said people used to think that the Earth was flat.

Although the heavens have been described in various ways as the umbrella that covers the Earth (Cai Tian myth), or as the circle around it (Hong Tian theory), or as empty as the celestial bodies floating freely (Xuan Ye theory) remains flat, though perhaps slightly swollen. If you were a flat person, you would not believe that such a thing ever happened, since the sun revolves around the sky like a circle. Since ancient Greek times, scientists have concluded that the Earth is round.

Surprisingly, there are still people who try to say that the Earth is flat, in part, in such things as the inability to see the curved atmosphere on the shore. If the earth were flat, the angle would be the same at both points. Although many measurements were incorrect, Ptolemy's concept of global cartographic integration, still in use today, was based on the assumption that the Earth was round, and indeed spherical. This meant that the rotation of the Earth was about 50 x 790 km = 39500 km.

Geodesy is the science that measures and regulates the size and shape of the Earth, including its magnetic field, and places points on the surface of the earth. But even without physical confirmation of images taken from space, many of the arguments used by the flat earth can be easily refuted using trigonometry or basic laws of nature. Many flat planets make great efforts to come up with other explanations for why the earth behaves as a circle when in fact it is flat, even though the Earth is aligned with the human perception of the earth in the past. a few years. a thousand years.

The flat earth's structure varies, but it usually involves a large disk-shaped surface with a small sun and moon orbiting it like lamps on a table.

Despite the scientific fact that the earth is round, pseudoscientific theories of flat earth are supported by modern flat Earth societies and, increasingly, by private individuals who use social media. But to put it bluntly, if the Earth were flat, it would mean that millions of scientists who deny that it is flat — and have done so throughout history — have conspired to do so in an incomprehensible way. Indeed, many flat-earth makers are more involved in conspiracy theories than they are in constructing an effective model of a flat earth.

But Effingham, who has been in contact with flat-earthers on Facebook, wonders if physics is the first place to fight these conspiracy-based ideas. Ashley Landrum, a Texas Tech University psychologist who also attended the Denver conference, acknowledges that flat-earthers are real and playful. Watch the latest episode of Vsauce to hear Michael give his best scientific explanation of whether the Earth is flat and see if it rises.

The flat earth model puts our planet in the center of the universe, but it does not think that the sun revolves around the earth. If the Earth were flat, we would find ourselves unable to explain everything we see in the sky, especially the sun, moon, and planets. If the earth were flat, we could see the same night sky from anywhere on earth. This could mean that the sun hits the whole Earth at the same angle, leading to the same shade.

This is because the Earth is round, so the way the sun strikes each place will be slightly different. If the Earth were flat but rotating, it would have a different shape at the time of the eclipse at different times of the day and night. So when the earth is flat and not rotating, the sun's rays always point upwards or downwards, when the surface in which we live becomes completely frozen or too hot to make water liquid, or it will turn. it will be horizontal, in this case, it would have been day and night, but all the water would have flowed out of the well because of Coriolis' strength. People who believe that the earth is flat believe that gravity would diminish, but there is no evidence that it works.

A flat object that weighs heavily on Earth will eventually collapse under the influence of the sun's gravitational pull, and then it will form into a round object. If Earth were flat, plate tectonics - the movement of solid plates that make up planetary plates - would not work, says James Davis, a geologist at Columbia University's Lamont-Doherty Earth Observatory in New York City. Many flat piles of the earth also reject gravity: the "British model" suggests that the disk itself accelerates to 9.8 m/s2 to provide the illusion of gravity. The problem, according to Davis, is that these interpretations are not based on mathematics or reality.

This can only be explained if the earth is round and orbits its axis. As the Earth rotates, half of the Earth faces the Sun, and a half - is on the other side. If the sun and the moon orb were to rotate on one side of the earth, there would be a rotation of days and nights. This would not only change everything we know about the structure of the planets but also about the structure of the stars (our Sun would have to behave in a completely different way to fit the flat earth theory) and what we do know about speed and movement in space (such as planetary orbits and gravity).
