The Earth spins on its axis once every 24 hours. This has been going on for millions of years. It will not be possible for the next millions of years to stop going around like this. To stop suddenly is even more impossible. But if the world stopped spinning, let’s think about what would happen as a consequence.
There may be two ways to stop traveling around the world. The first is a sudden stop, like a car braking. Alternatively, after millions of years, the rate of rotation gradually slows down and stops. So let’s think about the consequences of each of these two events.
If the world suddenly stopped
In practice, it is completely impossible to stop this way. But let’s think of it as a thought experiment.
First, let’s look back at the rotation rate that existed before the end of the world. At the equator, the Earth’s rotation speed is about 1,100 miles per hour. Further away from the Equator, the rate of travel slows down, and for someone standing at the South and North Poles, they would be spinning 360 degrees around where they are standing.
Before talking about what will happen if it stops, I will first discuss an important physics principle for this consideration. This is Newton’s First Law of Motion. It is a principle related to Inertia.
According to Newton’s first law, all objects with mass have inertia. Inertia is the act of “lazily dragging” objects with mass. Because of how lazy it is, a standing object wants to stay still without moving unless pushed from the outside. If the moving object comes from outside and doesn’t push or pull, it just wants to keep going calmly along its original path. This property of something that moves and wants to keep moving and something that is standing still is called inertia.
In other words, the attitude of not wanting to change is called inertia.
So these stationary and moving objects don’t change at all? No, it’s changed. When it changes, it changes when an external force comes and affects it. Therefore, to push a stationary object to move, to stop a moving object, or to change direction, you have to push or pull with some external force.
The best way to see Asia is by car. If you apply the brakes suddenly while driving, the car will stop, but the people in the car will want to continue on the original path because of the original inertia. That’s why when I stopped the car, I fell forward. It’s become something that floats out.
If the car suddenly crashes at a stop, the people in it will be stuck in the back and seats. According to Inasha, the people in the car want to stay in their original place, so when the car leaves, they stay in their original place and stick to the back of the car seat.
all right. So let’s say that the world has suddenly stopped. What do you think will happen?
Yes. It will be like when a car traveling at a very fast speed suddenly stops. The world stopped, but the people of the world did not. buildings. All the trees and animals will be blown away at great speed towards the old side, where the world originally revolved. At the equator, it will blow eastward at a speed of about 1,000 miles per hour.
people Not buildings. The water from the sea and the ocean will blow out to the east and hit the land as huge tsunami waves. Uncompacted mountains and the like will fall flat. If there are little birds in the mountains and hills, they will be blown away. The earth will be left as a pile of ruins.
If the world stops slowly
Let’s consider a more natural, slow-stop approach here. Let’s say that the rotation of the world slows down and stops after a few million years. What do you think will happen next?
There are two situations where it stops and becomes The first one is that the moon is always facing the earth, and the earth is always facing the sun. In this situation, the time it takes for the Earth to go around the Sun in a week will be the same as the time it takes for the Earth to go around the Sun in a day. If this is the case, one side of the world will always face the sun, so the day side will always be day and the side away from the sun will always be night. In terms of physics, it makes more natural sense to stop this way.
In this situation, the day side always gets the sun, so it will be scorching hot as if you were in an oven, while the other side is always night, so it will be shivering below the freezing point. In such a situation, the chances of survival will be very low. But it’s not completely unsurvivable.
Where the day side and the night side meet, it will always be evening (the same as morning). It is believed that the climate of the place where this evening is taking place is balanced, so the living things will be able to continue to live there.
Suppose the world stopped spinning completely.
In this situation, the Earth will no longer rotate at all, so the days and nights of the Earth will be determined only by the period of the Earth’s orbit around the Sun. When the Earth is on the other side of the Sun, one side will be day and the other side will be night. In the next 6 months, the Earth will be on the other side of the Sun. At this point, the side that was originally day will become night, and the side that was night will become day. In other words, Earth’s day will last 6 months and its night will only last 6 months.
If this happens, the daytime temperature will depend on how close the world is to the equator. In places close to the equator, it is hot during the day, and as you move away from the equator and closer to the poles, the temperature decreases. If they arrive at night, they will have to go through the cold and dark winter.
In this situation, the wind pattern of the world will change. The east-west wind pattern that is now blowing parallel to the equator will become a wind pattern from the equator to the South Pole and the North Pole.
weather Only the patterns of day and night and the patterns of the wind have changed because the world has stopped rotating. The world’s magnetic field is caused by the rotation of the Earth on its axis. If the world stopped, the magnetic field would gradually weaken. At this time, the protection provided against cosmic rays from the sun will be lost. As a result, most of the life on earth was destroyed by the radioactive waves (except for a small number of organisms that can be affected by radioactivity).
