What's the difference between writing a composition in the universe?

1. How to write a composition about the universe? The universe in my eyes.

The vast universe makes people look boundless. However, the word "boundless" does not seem to be scientific. Everything such as objects and space should have an end, and it can't be endless.

Our so-called "infinity" may just mean that the description is very broad and cannot be detected for the time being. If the universe has an edge, what is beyond it? What is "the edge of the universe"? This needs scientific discussion and practice to prove.

Here, I just put forward a daydream for reference. If a space or thing has infinite nature, then there is this possibility: infinite "hyperlink". What is an "infinite hyperlink"? That's like folders: A folder has countless B folders, B folder has countless A folders, A folder has countless B folders, and B folder has countless A folders … and so on. Just as a universe has countless molecules, a molecule has countless universes, and a universe has countless molecules ... this situation will continue indefinitely. And the outermost layer of this "very small" universe should have a film that will not be destroyed. At least something that can destroy it hasn't appeared yet, or the universe will be destroyed! ) And all the "universes" with different sizes and great differences, like many doppelgangers, are doing the same action at the same time, and the same situation is happening at the same time. The same two objects will never meet, because they will be blocked by the film of the universe.

If so, then the macro decoding and micro results are the same result-everything is made up of the universe. And countless small universes make up a big universe, but countless big universes make up a bigger universe. However, both the small universe and the larger universe are doing the same thing. As long as one universe is threatened, all other universes will be threatened at the same time. The same thing will happen in so many different universes, that is to say, in all spaces, there are countless identical things and countless selves!

However, in any case, no matter how to speculate, the final conclusion still needs scientific exploration and discovery to effectively convince other concepts. I just put forward a daydream here!

2. Write a composition in (another universe). I lay on the green apartment and looked at the blue sky.

The starry sky pours into my eyes and gurgles in my body, telling me a secret: the distant place, on the other side of the universe, is the reflection of this shore. There are the same cities, the same streets, the same houses on the streets and the same children in the houses.

Is that child another me? When I got up, had he finished school? When I look at Varan's sky, is he lying on the lawn thinking about me? Where will our eyes meet?

On this side of the universe, trees will sprout again in spring; So, on the other side of the universe, trees sprout in summer? On this side of the universe, wear cotton-padded jackets in winter; So, on the other side of the universe, do you wear cotton-padded jackets in summer?

On this side of the universe, small flowers quietly open; On the other side of the universe, will he fly around like a butterfly? Or sing loudly like a bird?

When I was having dinner at night, I suddenly thought that on the other side of the universe, another me was having breakfast?

The bell rang and we played games on the playground. On the other side of the universe, what is their game like? Do they race against trees when they play hide and seek?

On the other side of the universe, the addition is like this: everything on earth, plus ten miles of richness, is full of vitality. At that time, countless children will rush out of their homes to enjoy flowers, swim and fly kites ... In this way, everything on the earth, plus the spring breeze of ten miles, is equal to the festival of countless children.

The multiplication is like this. "Autumn October" multiplied by "autumn water * * * shooting in the sky" and then multiplied by "autumn leaves" is equal to "the lake and the autumn moon set each other off as an interest", equal to "stopping in the maple forest late, the frost leaves are red in February", and finally equal to "I wish people a long time".

On the other side of the universe, I am curious about that.

3. Composition When I was a child, my parents went out to work and lived with my grandparents. Grandma is fierce. When I was very young, she hit me with a bamboo board. When I get up late, I will hit her. If I eat too much or eat too little, she will scold me. When I was a child, I could only hide in my room and think silently, why did two old people take me away? Why don't parents come back. Every time I see children who live with their parents come to me, I usually scold them. Of course, those children will naturally isolate me.

Later, I can't remember why my parents had a big fight. I only remember that day, my parents had a big fight, and the word "divorce" seemed to come out soon, but it didn't happen as I expected. My mother just sighed lightly. The next day, she got on the early train, left the county and went to work in another city. After mom left, grandma was no longer so grumpy, and the family atmosphere became better and better. My relationship with my classmates is getting more and more harmonious, and everything seems to be developing in a good direction. However, new gossip has come again. Because I have a good relationship with a boy in my class, some people say that I am stalling with him. At first, only a few people were talking about it. Later, the number of people increased, and the stories made up became more and more authentic and the momentum became more and more huge. After seeing it, the boy and I had to make a detour. At that time, I seemed different.

No manuscript can be reproduced without permission.

Different? This is really a show-off topic. Me? Different? I think the only difference between me and the public should be my troubles.

Later, when I grew up, my parents went home and took me to the county. At that time, grandpa had passed away, and grandma went to the county with us. I thought everything would be fine in the county, but who knows, the collective isolation of classmates, the quarrel between parents and grandma's increasingly grumpy temper have made the already tense family relationship more rigid. At school, I have to face the cynicism of my classmates and stare at my parents when I go home. Boys and girls of this age are lively and sunny, and most of them are worried about their exam results. Therefore, it is doomed that these flowers in the greenhouse don't understand my troubles, so it is doomed that I will be different from them.

4. Who wrote the composition of the universe? The universe is the space where we live. The original meaning of the word "Yu" means "up and down". The ball is our home; The earth is only the third planet in the solar system; The solar system only settled on one side of the huge spiral arm of the Milky Way; And the Milky Way, among all the galaxies in the universe, may be very inconspicuous ... All these constitute our universe: the universe is the home of all celestial bodies. The universe is also our time, and the original meaning of "Zhou" is "eternal". Because our universe does not always exist, it also has a process of birth and growth. Modern science found that our universe was formed about 20 billion years ago. In a spectacular big bang, our universe was born! This is the famous big bang theory. ) once the universe was formed, it has been in motion. Scientists found that the universe is expanding and the distance between stars is getting bigger and bigger. What will be the future of the universe? Many scientists are working hard for this. This may always be a mystery, a fascinating mystery.

Besides, how far are these suns from us? How big is the universe? Have aliens really visited the earth? ..... Facing the vast, beautiful and mysterious space, I put forward one question after another with curiosity that has puzzled me for a long time. Since reading the book "Thousands of Why", I have lost a lot of question marks in my mind. The knowledge in the book is what I want to know most. Every time I read a story, I am intoxicated with it, just like floating in space and feeling the life of an astronaut. You can also contribute to the existence of aliens. This is the question that interests me most. Now, the mystery is finally solved. The answer is: aliens exist. Because there are so many stars in the Milky Way, and scientists have found that half of the stars in the Milky Way are alive, aliens must exist. But whether aliens have visited the earth is still an unsolved mystery. In fact, the universe is not as mysterious as we thought. It is still a mystery, but I firmly believe that one day, it will become a very clear universe. The world in my eyes is novel everywhere, always fresh, and countless strange "why" accompany me into more unknown worlds! Although there are still many question marks, I have gradually improved my understanding, thinking and creativity, and I will turn the remaining question marks into a full stop.

5. Composition in the Universe 2 100 A.D. 2 100 A.D., with highly developed science and technology, achieved world peace.

Human beings have become very long-lived because of gene cracking. At this time, the population of the earth has exceeded 654.38+0.3 billion, and the problem of survival seriously threatens mankind.

The "Sun Federation" decided to form a cosmic expedition to search for a new living "planet" on behalf of mankind. I had the honor of being appointed captain of Chineydy by the Federation. I immediately selected 39 astronauts and 6 intelligent robots to fly Xingyu out of the "Milky Way" and into the depths of the universe at an amazing hyperspace speed of 60 million light years when the earth was around.

We have been to dozens of "galaxies", but all of them can't survive because of the high temperature and lack of water and trees. In desperation, a new "solar galaxy" appeared in front, and the sun was light green.

Then we found a star several times larger than the earth, with a vast ocean and green space. We were ecstatic and landed the spaceship on this "planet". I took 26 astronauts and 3 intelligent robots, armed to the teeth, wearing helmets, body armor and laser guns, to explore the mystery of this "planet".

This "planet" is like a fairyland. The towering virgin forest is lush, and all kinds of exotic fruits are covered with branches. Flowers and plants are everywhere, birds are singing and their voices are sweet; The flowing water in the river is crystal clear. Even so, there is not a trace of people here.

I found that all the animals and plants here are several times to hundreds times larger than the earth. Suddenly, a big eagle passed overhead with a python more than ten meters long in its mouth.

Several giant shrimps with dozens of legs are resting in the river. One is ten meters long, with a fish body and a shovel head, with one eye facing down and the other eye facing up, and its mouth is particularly large. They are swallowed in one gulp and become food for the stomach. Then surfaced, "Lulu", sound like thunder.

A giant lizard ten times bigger than Komodo dragon heard the sound, opened its jaws and bit the fish at lightning speed. It's really "mantis catches cicada, yellowbird comes last".

We also saw many extinct animals and plants here. As night falls, the "light blue" moon rises to the sky.

We took out a space box and opened it to become a well-equipped house. Suddenly, a deafening sound came, and a group of prehistoric killer giant mosquitoes as big as footboards came at us.

We were shocked, looked at each other and our hearts were broken. We picked up the laser gun to shoot, but it didn't help, because there were endless giant mosquitoes.

After three hours of fierce fighting, everyone was exhausted. I see giant mosquitoes like to jump on heat. I lit a huge fir tree with a laser gun. Mosquitoes immediately pounced on the pillar of fire, wave after wave, until the last mosquito died, and there were bodies everywhere, all of which were the bodies of giant mosquitoes. This species has since become extinct.

At this time, everyone is exhausted and have a rest. At dawn, the "light green" sun rises in the west.

We continue to explore against the "light green" sunshine. There are triangles, hexagons, heptagons, octagons and nonagon everywhere. Squares, rectangles, diamonds, parallelograms and other fruits such as diamonds, pearls, agates, rubies, sapphires, amethysts, emeralds, etc. are all exotic fruit trees with different shapes and varieties that have never been seen before. I can't help but take off one and look from the left. I couldn't help taking a bite. It's delicious. It can secrete human heart and lungs.

Everything seems so magical and beautiful. After comprehensive exploration, we have determined that this place is very suitable for human life and residence.

We finally succeeded and became the savior of the earth. We immediately report to the Federation. Three hours later, a large number of spacecraft roared and landed on this pure land just named "Chineydy Celestial Sphere", and designated this place as a land of new immigrants. I will continue to explore the mysteries of the universe and make brilliant contributions to mankind forever.

Note: 1. Inverted stars, the sun rises in the west. Looking at the sun from different angles on the star, there will be four colors: blue, green, yellow and red.

Due to the rapid rotation of the earth (427 days), prehistoric animals and plants are huge.

6. Please refer to ~ ~ ~ ~ ~ ~ ~ for the composition about the universe.

The place where we live is the earth, and there seems to be no earth in the universe.

Like a planet. Because the universe is too big! In the vast universe, there is the Milky Way.

Department, now we know the relevant knowledge of the Milky Way, but the secret of the universe, for

We are still a mystery! There are more than a dozen planets in the Milky Way where we live.

Ball, fiery red sun, beautiful Saturn surrounded by halo, cold Pluto,

Mars, Mercury, Uranus and so on.

The moon is the smallest planet. It is only a few million kilometers away from our earth.

It is far away, but our world has a long history of landing on the moon. At that time, the American grandmother

Tear, driving the Apollo spacecraft to land on the moon, there is no space on the moon.

Gas, so astronauts must carry heavy oxygen tanks. Lift a piece on the moon

Big rocks, don't bother, because the gravity on the moon is smaller than that on the earth.

The weight is only one sixth of that of the earth. How's it going? Is it light? Eclipse, me

I'm sure you've seen it. That's because the sun didn't shine on the moon, but the earth just blocked it.

The rays of the sun, so there will be a solar eclipse.

The sun is the largest planet in the galaxy! Its surface temperature is 6000 degrees Celsius,

The central temperature is about three thousand times the surface temperature! It's almost1500,000 degrees Celsius,

This temperature is really a miracle of the universe! Even if something touches it, it will

Turn into gas, ah! This is an amazing temperature. We [for example]: If we take a step,

Ok, it will take more than 3500 years to go to the sun, that is, by plane [jet plane]

Type], also want to fly for more than twenty years! We see the sun on the earth, but it is small, because.

Because the sun is too far away from the earth, it is so big!

There are many planets bigger than the sun! The sun is a star. These two stars also

Big enough! Betelgeuse is more than 200 times the size of the sun! Betelgeuse is the planet of the sun.

More than 500 times, what an amazing number!

The universe is infinite! The universe is a treasure house, which contains a lot of knowledge.

Know! He is waiting for us to dig for "treasure" when we grow up, and I want to be one when I grow up.

An astronomer, to explore this mysterious universe!

7. Composition about the universe Today, my father and I went to the museum to visit the "Exhibition of Human and Space Science".

As soon as I entered the hall, there was a sea of people. Many children are visiting the exhibition. Some of them point and observe different models carefully. Some people took out paper and pens and carefully recorded information about satellites and rockets. All kinds of satellites are displayed around the hall, including Dongfanghong-1, China's first artificial earth satellite. There are several long "hairs" on the round head, and it seems that they are still in space around the clock. There is a "Fengyun II" meteorological satellite wearing a sweater made of 20,000 solar cells; There are a pair of communication and broadcasting satellites with long wings, as if they were still roaming in space; Shenzhou V, China's first manned spacecraft, was displayed in the most conspicuous place. I looked at Shenzhou 5's heroic posture and imagined Yang Liwei's magnificence of "cruising the sky and seeing thousands of rivers" in space. My heart is very excited: beautiful space, we China people have finally arrived! Magic space, how many secrets do you have? Let's uncover and explore. !

8. Write a composition about imagining the universe. The night sky is beautiful. There is not a cloud in the sky. The deep blue sky is full of diamond-like stars. "Sou" a meteor drew a silver sickle mark on the horizon, "Yi" the blue curtain was scratched. The moon and the stars meet, move in an instant, and flicker. Take a deep breath and let the fragrance of flowers and plants pass through your teeth and blend into your cavity. The feeling of breathing and suffocation was suddenly sent away, but the dying fragrance was still turning. "Jump" sank, leaned back and landed in the soft green haystack, which made people itch. Before you know it, it was midnight ...

The blue sky of the lake reflects the moon, which is high and shimmering. Some chilly wind blew over cheeks and flowing long hair, and everyone fell asleep: flowers bowed their heads, grass leaned sideways, and trees snored and made a "rustling" sound. The moon is bright, the wind is clear, and it is like a sarong around the earth. Singing the wind and the moon, the shadow of the moon is dancing, and the cloud quietly runs to the front of the month, covering its graceful figure, which is still somewhat blurred in the haze.

"There are thousands of trees in the east wind night, the wind blows down, and the stars are like rain. BMW carved cars are full of incense. The phoenix flute moves, the jade pot turns, and the fish dragon dances all night. " (Selected from "Jade Case Yuan" Xin Qiji) Black gradually filled the sky, countless stars broke through the night, and the moisture of the night infiltrated the air for a long time, filled with sentimental atmosphere. Looking up at the sky, the starry sky is particularly clear, and the stars in the distance shine like tiny tears. Xiao Yue's remnant stars are playing in the air. Yue looked at her children and smiled like a crescent moon. The stars are still playing, hiding and jumping. More and more children joined in, forming a warm scene. Unconsciously, it has filled the sky, like a gorgeous evening dress, dotted with granular diamonds, dazzling.

Through the atmosphere, look! Where is this? So vast, so deep, so charming, ah! This is the universe. In the vast universe, countless planets are showing off their costumes, including red, yellow, green, purple and colorful ... they are all spectacular. Wow, are they dancing? When they formed a circle, they began to dance. Dance is beautiful, complicated and unpredictable. The harder they dance, the more energetic they are. In a blink of an eye, the universe became a ballroom and the Milky Way became a dance carpet. Everything is so ethereal and charming, but this is just the tip of the iceberg.

Ah, how mysterious the world is, and how much I don't know? Let's continue to explore!

9. The difference between space and the earth 400 words Space is the sea, and the earth is a small fish in the sea. Of course, this small fish can't swim at will.

The earth is an ordinary and special celestial body. It is common because it keeps going around the sun like the other seven planets, and its direction and orbital shape are similar, almost on the same plane. Therefore, the cosmic environment of the earth is safe. Especially because the earth is different from space, it has a variety of extremely rich biological species.

The earth has day and night, and the cycle is 24 hours. Space is not like this. It has no day and night, only bright and dark areas. The earth has enough gravity, so people can walk freely, but not in space. In space, people are like floating dust. The earth is full of oxygen, and people can breathe freely, but not in space. In space, people can't live without oxygen-making devices. The earth has enough fresh water, so people can live and breathe, but not in space. In space, at least there is no liquid water, so space is dead.

Our earth is so beautiful! We should cherish our earth!

10. See who wrote the composition "What's in the Universe" well. On the night of Mid-Autumn Festival, the moon is bright, and the ancients regarded the full moon as a symbol of reunion. Therefore, it is also called "Reunion Festival".

Throughout the ages, vagrants who have lived in other places have pinned their affection on the moon. "Looking up, it turned out to be moonlight, and then sinking, I suddenly remembered my hometown." The spring breeze is green in Jiang Nanan, when the moon shines on me by the poet Li Bai in the Tang Dynasty, and Wang Anshi's "People have joys and sorrows, and the moon is sunny" in the Song Dynasty.

Poetry, etc. , are eternal songs. From a scientific point of view, the moon is the only natural satellite of the earth and the closest celestial body to the earth. Its average distance from the earth is about 384,406,5438+0 km. Its average diameter is about 3476km, slightly larger than the earth's diameter 1/4. The surface area of the moon is 38 million square kilometers, which is not as large as that of our Asia. The mass of the moon is about 735 billion tons.

The moon we usually see is like a bright lamp. The moon itself does not shine, but reflects sunlight.

Its brightness varies with the angular distance between the sun and the moon and the distance between the earth and the moon. The surface of the ball is a desert composed of plains, peaks and valleys. There are also many craters formed by high-speed impact of space objects on the surface of the moon. There are also various special names such as ocean, sea, bay and lake.

The crater is a bowl-shaped pit structure. There are more than 33,000 craters with a diameter greater than 1km.

Many craters have a central peak or peak group in the center. The dark black spots seen by the naked eye on the moon are called the Moon Sea, which is a vast plain.

There are 22 months of the sea. The largest is the storm ocean, covering an area of 5 million square kilometers.

Because there is no atmosphere on the moon, the heat capacity and thermal conductivity of the materials on the surface of the moon are very low, so the temperature difference between day and night on the surface of the moon is very large. The moon revolves around the earth in an elliptical orbit. The great circle cut by this orbital plane on the celestial sphere is called the "white road". The plane of the ecliptic does not coincide with the equator of the celestial sphere, nor is it parallel to the plane of the ecliptic, and its spatial position is constantly changing. The period is 173 days.

The average inclination of the moon's orbit relative to the earth's orbit (ecliptic) is 5 09'. The moon revolves around the earth and rotates at the same time, with a period of 27.438+066 days, which happens to be a sidereal moon, so we can't see the back of the moon.

The libration is a wonderful phenomenon, which enables us to see 59% of the surface of the moon. The main reasons are as follows: 1. In different parts of the elliptical orbit, the rotation speed does not match the revolution angular speed. 2. The intersection of the white road and the equator.

The cycle of the moon's rotation around the earth: 29.059 days in the first lunar month; Stellar moon 27.3 166. Do you know that?/You know what? Do you know that?/You know what? During the operation of the moon, an eclipse will occur when it enters the shadow of the earth.

How did the solar eclipse form? When the moon enters the penumbra of the earth, it is a penumbral eclipse; The moon enters the shadow of the earth and a partial lunar eclipse occurs; The moon all enters the umbra of the earth, which is the total lunar eclipse. Speaking of total lunar eclipse, I will tell you an interesting legend:1At the beginning of the 6th century, Columbus sailed to Jamaica in South America and had a conflict with the local aborigines.

Columbus and his sailors were trapped in a corner, without food and water. The situation is very critical. Knowing that there would be a total lunar eclipse that night, Columbus shouted to the natives, "No food, no moonlight!" " "In the evening, Columbus's words came true, and there was no moonlight.

When the natives saw this scene, they were afraid, so they quickly made peace with Columbus. Eclipses always occur in sight (full moon), but not every time.

Under normal circumstances, the moon either passes above the Earth's umbra or leaves under the Earth's umbra, and rarely or partially passes through the Earth's umbra, so an eclipse will not occur under normal circumstances. There is more knowledge about the moon.

Let's study hard and solve unknown problems.
