Varlaug said that the earth is a doughnut. What's going on? Watermelon video takes you to explore.

do you think that science is rigorous? Not really! As we all know, the earth is a round sphere, but some scientists think it is actually a doughnut shape. What's going on? Let's take a look at the watermelon video creator "Hipopularization".

in p>28, at the forum of horizon society, the theory of earth doughnut was put forward for the first time.

In p>212, Varlaug added a complete argument and details for this theory: the doughnut-shaped body is scientifically called a ring planet. In order to prevent the outer ring from collapsing to the center of the earth under the action of gravity, it must maintain centripetal force and centrifugal force through rapid rotation; The light does not turn with the curvature of the edge of the environment, and we can't see the hole in the middle because the light will be weakened and reflected when it goes straight.

Therefore, theoretically, it is possible to have a doughnut-shaped earth. Although planets do not naturally form doughnut shapes, the laws of physics allow the doughnut-shaped earth to exist. What if the earth really becomes a doughnut?

The escape speed of the doughnut near the equator will become smaller, about 6.5 thousand meters per second, making it easier to launch a rocket; The gravity in different places is different, and the equatorial position will probably drop to 3%. Walking in these places is like jumping on Mars, and there will be no fat people (because the weight is three times lighter than before).

due to the unstable structure of the doughnut-shaped earth, in order to maintain the existing shape, it is necessary to speed up the rotation speed and increase the centrifugal force to maintain its own stability, which will lead to many sunrises and sunsets within 24 hours, which will greatly affect the life and rest of human beings and the reproduction and migration of animals.

The moon may be pulled to swing back and forth in the middle of a doughnut, or form a figure-of-eight earth orbit, which will cause the water level in the ocean to become very unstable and some coastal cities will be submerged; Earth-shaking changes in the overall climate on the earth will make the polar regions colder and the equatorial regions hotter. In addition, affected by storms and hurricanes, some areas will become very desolate and no longer suitable for human habitation.

it is difficult to predict where different countries will be located on a torus. The living division of human beings will become different. Some people like to live there, while others like to live outside. This kind of earth will make us have a completely different life. Maybe people will never cross the ocean and only evolve on different continents. Maybe we won't have mass extinction again, and some disasters in the history of the earth can be avoided.

The doughnut-shaped earth is just a hypothesis, and no one knows whether the result is good or bad. However, as a member of the earth, no matter whether our earth is a doughnut or a jelly bean, even if it is a piece of paper, we should love it and cherish it. Don't wantonly destroy the living environment she brought us, and don't wantonly destroy the living materials he brought us.

We already know what will happen if the earth becomes a doughnut. What will happen if it never rains again?
