Why Stars Don t Fall Essay

There are three good friends living in the sky, they are red eyebrows, red noses, blinking red eyes, mischievous red stars; Yellow eyebrows, yellow nose, obedient yellow stars with yellow eyes in the wink; Green eyebrows, green nose, and cute green stars with green eyes winking.

They play together every day. One day, they started playing hide and seek again, as usual. The green stars come to find it, and the red and yellow stars come to hide.

Red Star piles cotton-like white clouds into a snowman and hides in it himself. The yellow star lies on the cloud, and then pulls down a cloud over the body. The green star found them in a short time, but the red star accidentally fell.

Impartiality happened to fall on a big tree. It's red, it's flashing, it's like a red light. Suddenly, all the cars stopped.

Red Star asked strangely, "Why don't you leave?" ”

The car said, "Because you're a red light!" You have to wait for the green light to come on before you can go. After a while, the road was full of all kinds of cars, and the driver honked his horn vigorously and said, "Change the green light, change the green light!" ”

But where did the green light come from! ”

This scene was seen by a passing bird, and hurriedly flapped its wings to find the green and yellow stars. The green and yellow stars came in a hurry. The three stars are all together, but everyone doesn't know what to do.

The little bird shouted at the top of his voice: "Red star, yellow star, close your eyes, let the green star open your eyes." The red and yellow stars immediately closed their eyes.

The road is clear again.

The main reason why stars don't fall is that they are too far away, and the gravitational pull of the stars has a negligible effect on the Earth. The planets and stars visible in the universe are quite far away from the earth, and all of them have their own positions, so they will not fall to the earth.

Something on Earth that is in mid-air falls because there is gravity on Earth, but gravity is not strong enough to suck stars in. Of course, unless other planets are too close to the earth, it will lead to disasters such as asteroids hitting the earth, and the planets floating in the universe are forced by each other or from the universe because of each other's forces, in short, the forces are complex. But in the end, they will make them float in the universe and form their own orbit.

In the vast universe, it was originally indifferent to the difference between up and down, and when I was a child, looking at the stars in the night sky always made people have many beautiful reveries and questions: for example, why don't the sun, moon and stars in the sky fall? Isn't it uncomfortable for Americans to live on the earth at our feet, hanging upside down with their heads down?

And so on ridiculous questions. At that time, I always felt how beautiful life in heaven was.

But as I grew older, my experience and knowledge increased, and I gradually realized that in fact, there is no difference between up and down in the vast and infinite universe. The reason for this illusion is simply that our reference points are different, and the feelings we get will be different. The so-called up and down is just an illusion generated by people.

If the stars in the sky could fall off the chain and hit, I would not be afraid when I walked in the dark night without street lights, as long as I held the stars in my hands.

If the stars in the sky could fall, I would sit on the back of the stars, and the twinkling little stars would carry me to space.

If the stars in the sky could fall, when the power went out, I would put the stars on my desk, and the twinkling little stars would be by my side so that I could finish my homework.

If only the stars in the sky could fall! I followed the little star to find out the secrets of nature. Why do grapes hang on vines? Why do watermelons grow on the ground? Twinkle and twinkle little morning shirt stars, even the secrets of nature told me, it's amazing!

If the stars in the sky can fall, I will take the little stars to find Sister Moon and Father Sun and make friends with them.

Stars don't fall mainly because of the various forces in the universe that interact with each other.

The stars seen on the earth now are basically stars in the universe, these stars are not on the earth, things on the earth in mid-air will fall because there is gravity on the earth, but gravity is not enough to attract other stars, if other planets are too close to the earth, it will lead to disasters such as asteroids hitting the earth, and the planets floating in the universe are forced by each other or from the universe. In the end, these stars will float in the universe to form their own orbits, so there is no such thing as falling.

All the stars orbit according to their own orbits, and none of them are tied to ropes and hung in the universe. In order to explain why the planet does not fall, Niu Dun discovered the "law of universal gravitation". That is, there is a force between the planets that keeps him moving in radius and speed.

Whereas, spike-limbed objects on Earth will return to the ground due to the gravitational attraction of the Earth.

Meanings and symbols of various stars:

1. Symbolic meaning: The stars themselves have a certain symbolic meaning. For example, the sun and stars usually represent warmth, justice, light, truth, hope, etc.; In classical Chinese poetry, the sun will represent the monarch, the other astrological days are strong, the evening is twilight, the North Star represents the monarch, and the Beidou represents the big names.

2. Romance: Stars are synonymous with romance. At the edge of the Milky Way, 30,000 light-years from Earth, there are two huge galaxies that stage "tango".

These two galaxies are made up of billions of stars and clouds of gas, both of which are resistant to spirals. The stars, gas, and dust of the Chang Chun large galaxy on the right form an "arm" that surrounds the smaller galaxy on the left, slowly performing various graceful dances in interactions.

3. Hope of life: The stars represent the hope of life, like the Big Dipper in the night sky, which can lead the confused people out of the labyrinth, so it has the meaning of hope for life. <>

The main reason is that the distance is too far away, and the gravitational pull of the stars has little effect on the Earth. Including visible planets.

Stars are quite far away from the Earth, and they all have their own positions, so they don't fall to the ground.

In addition to the stars, there are planets in the sky, which are much smaller than the stars and do not emit light, they all revolve around their own "sun" like the earth.

They also have their own orbits, and they do not collide with each other and do not fall to the earth. And the meteors that flash in the sky are mainly fragments of some fairly small stars scattered in space, not the stars in the sky that everyone sees. Meteors sometimes fall to the ground, so they are called meteorites.
