The earth is suspended in the universe, if the earth will fall, where will it fall?

Have you thought about the same thing? Earth appears to be suspended in space. Earth is too big. How can you not get hit by cosmic rays?" This may be because there is a huge magnetic field inside the earth, and this magnetic field is strong enough to attract everything on the surface of the earth. Why not go down? Like the picture below.

Earth and the Moon in the Universe

Have you ever wondered where the earth would fall if it happened? How do you live in space? How will it adapt to the weightless environment? Can it fly out of the atmosphere? Will it be swallowed up by cosmic garbage... it's all waiting for you to answer! Let's discuss it together.

I ask you a question, what's wrong? Under where? We would say, "The earth below us is sinking, and the sky above us is rising." This is what we usually mean by ground and sky. But what if someone told you that there is a giant pyramid on the ground and only one star in the sky? Then, you must think he is wrong! how can that be possible? Yes, it is true.

flat earth

In ancient times, most people believed that "the earth is flat", that the earth was flat. Later it was proposed that the earth is a sphere. But in ancient times, it was too bizarre for people to accept. Then there is the rebuttal to the "geosphere": since the earth is a sphere, there must be a part of the world that is "inverted". If the earth is likened to a round ball, then the ball cannot rotate peacefully, nor can it maintain a level state; it can only rotate when it is artificially created. And these "inverted people" are in danger because they "fall down"!

Are people in the southern hemisphere upside down?

This seems to make sense if we gesture with the globe. However, do you know what the shape of the earth is? Actually, it is not round. So, what kind of thing is the earth? The earth is also called a revolving sphere, also known as a spherical ball. People who live in the northern hemisphere are very busy, and people who live in the southern hemisphere, especially those who work in Antarctica, are very busy. Will they "fall off"? Is that true?

Obviously not. Whoever lives anywhere on earth has their feet on the earth and the sky is blue above them. How did the handstand happen? Because people's feet are tall and big. And they're always on high. And the sun in the sky always shoots light toward the lower part, so the phenomenon of head down occurs. They will all fall to the ground, where will they fall?

The man in Antarctica

On Earth, by fall, we mean falling from a high place to a low place. Why does this happen? This is because any object on Earth is subject to Earth's gravitational pull. If you want to throw an object high, it has to have enough force to overcome gravity; not vice versa. Under the force of gravity, all objects fall toward the mass of the Earth. The center of the Earth's center of mass is directly below. The opposite direction is above.

moon in the sky

After thinking for a while, "A full moon, like a bright lamp, hangs high in the sky." If you can read this text, then you must know what's going on! There is a passage in the lesson "The Phases of the Moon": "When the moon rises, it is a little brighter than the sun; but it sets quickly. This sentence about the moon tells us that the direction of the moon on the earth is What? The moon is in the sky, above the earth, of course.

This is a picture of the earth on the moon. The situation has reversed, and the earth is hanging high in the sky. What a concept! If you know that the moon has a big sphere, then you will understand why the earth puts itself on it! The reason is simple: because the moon is as high as the sun! So, is the earth on the moon or below the moon?

see earth from the moon

From the moon, the earth appears to be above the moon. It's not like that. The earth is still under the moon. "Why is that?" The moon is Earth's moon. It revolves around the earth. If we consider the surface of the earth as a sphere. Then, there is a curve between the earth and the moon. This line is called the Earth's axis. This axis is what we call the geocentric line. The moon orbits the earth, as do the satellites and space stations above it. There is a common feature between them: that is, the orbits of the two basically coincide. That is, there is no difference between them. However, due to the different environments in which artificial satellites and space stations are located, there are certain differences between the two. Except that the orbits of artificial satellites and space stations are closer to the earth, ranging from a few hundred kilometers to tens of thousands of kilometers. The moon is farther away, with an average distance of 384,000 kilometers.

Tiangong Space Station

The Tiangong space station is 400 to 450 kilometers away from Earth. If you observe the Earth from the Tiangong space station, the Earth is directly below the space station. Not long ago, SpaceX Musk's Starlink satellite was destroyed by a geomagnetic storm. This shows that there is something similar to the geomagnetic field in space, which can change the direction and speed of the movement of objects around us, resulting in various effects. For example: earthquake; hurricane, etc. Under the influence of Earth's gravity, these destroyed satellites will eventually fall to Earth. In the same way, the moon is also the moon of the earth. It orbits the Earth under the influence of gravity. When you see a planet orbiting in space, you can determine the position and velocity of that celestial body. So, how should this track line go? Let's take a look together! The point of gravity is just below. When the moon "accidentally" falls, it also falls to Earth.

sun below earth

If the Earth "falls", where will it go? You may not have answered this question! In fact, this is just a simple physical common sense. So why think so? We know that Mars and Jupiter are the closest in the solar system. Seeing this, I think we have found the answer. The earth revolves around the sun by the gravitational force of the sun. If the earth falls again and again, it must have landed on the top of the sun. That is, the sun is below the earth.

Not only Earth, but also the other seven planets in the solar system. The seven planets are Mercury, Venus, Mars, Jupiter and Saturn. There are many small celestial bodies on the planet that we can see with the naked eye, some of which are easy to find. But other small celestial bodies are less noticeable. If they fall, they will all fall on the sun.

So why didn't the earth fall on the sun? Because water on Earth does not evaporate, water cannot be carried away like air. If one day "water vapor" does appear on the earth, what will happen? Is there really water vapor? This question is also simple. Let's throw a rock and see.

throw stones

If we pick up a stone and throw it hard, it will fly for a while and then fall to the ground as if we were throwing a stone. If we throw the stone heavier, it will fly in the air for a long time before it hits the ground. This is because the heavier we throw, the faster the initial velocity of the stone, the further it flies and the longer it stays in the air. So we must have a lot of strength when throwing stones. However, when people throw stones with a lot of effort, no one can guarantee that they will successfully hit the target every time. Why can't it be sent over there? If we throw the stone hard enough that its initial velocity is fast enough, it will travel far enough to orbit the Earth. So, will it never land?

Newton Cannon

So did the British physicist Newton, who was often crushed by the "coffin board". Newton said that if the cannon was mounted on a high mountain, if the cannon was strong enough and the cannon fast enough, the shell could revolve around the earth without falling. However, he did not expect that this idea was later realized, and a magical and powerful weapon-gunpowder was really produced. However, this weapon was invented by a man named Newton. His name is Newton. This powerful cannon is called the Newton Cannon.

After all, Newton was a very good physicist, mathematician and astronomer. Not only did he think so, but he also calculated the speed he would need if the shell didn't fall. The speed of the vehicle is 7.9 kilometers per second. This speed is also known as the first cosmic speed. Before this, Newton had calculated the speed of 100,000 kilometers per second. So, when we measure it as a yardstick, Newton is one of the greatest scientists in the universe. So why is Newton said to be the father of the universe? Spacecraft above the earth have such a speed that the centrifugal force generated by their circular motion around the earth will be balanced with the earth's gravitational force, and will not fall off.

The Earth goes around the sun

Likewise, the Earth is a cannonball fired from Newton's cannon mounted on the sun. But what if you were wondering if Earth would fly off a planet? The answer is probably not. Because the earth is a "big" planet. It has a large and complex system. The earth does not fall on the sun because it orbits the sun at a speed of 29.78km/s. The rotation of the Earth's revolution produces enough centrifugal force to counteract the Sun's gravitational pull. Therefore, the Earth does not fall on the Sun.

jumper

Look here, should the original question in our minds, "Earth looks like it's suspended in space", should be solved? But now it seems that this question is not so simple, because it reflects the deviation of our understanding of the relationship between the earth and the solar system. This question is also interesting if you look at it from another angle. Why does the earth hang in the air? Earth hanging in space is an illusion. Like when a person jumps and we press the shutter of the camera, we freeze when he jumps.

Earth is thrown to the ground by the sun's gravity

In fact, the Earth and all the planets in the universe are moving at high speed under the influence of gravity. They are more like small balls thrown on a rope. When it is thrown up, an object will gradually rise to the highest point with its speed, and then slowly fall again until the whole sphere disappears. This is the "hover" phenomenon. The levitating phenomena we see are only moments when they freeze. Does everyone think so?

If the earth falls on the sun, what about the sun? Where will it fall? How is the Earth's orbit determined? Before this question, let's first understand the relationship between other planets and stars in the solar system. Do you want to know? Let's chat!
