Traveling on the edge of the universe

1. Real scientific knowledge in A Journey to the Edge of the Universe

We can't reach the edge yet. We can't see anything but light. We observe from one side through the earth, and the maximum is 65.438+037 billion light years. So if we look near the earth from that boundary of the universe, the earth is the limit. What is farther than the earth? I don't understand this.

Although the speed of light is considered to be the fastest at present, it is the speed of motion of objects, and the speed of space expansion is faster than the speed of light. Therefore, if we really run to the edge of the universe, no one knows what it will be like, because we don't know whether the universe has boundaries or not, and we can't observe the boundaries of the universe.

With the earth as the center and a radius of 65.438+037 billion light years, such a sphere is the limit of human observation. No matter how far it is, the light hasn't arrived here yet. How can we observe it?

I made it myself. what do you think? Do you want anything?

2. About traveling to the edge of the universe

Knowing things from the earth is bound to mislead us. Three scientists proved the result that the universe is expanding and won the Nobel Prize. Actually, I think it's a big joke.

In fact, the universe has no center and no margin. The so-called center and edge are limited contours. In the infinite universe, we can't argue these questions with the thoughts of earthlings, but science always gives answers, because human beings believe that the universe was born by explosion, because they believe that explosion will inevitably determine that the universe has a center. Since there is a center, they also believe that there will be a margin, and the expansion of the universe will pay off.

On the earth, many things will volatilize and disperse, and even if things in the soil are left for a long time, they will decompose. Since man invented the atomic bomb, people have been conquered by such power. Some scientists say that destroying the moon with an atomic bomb will make the ocean lose its tides.

In fact, in space, granular substances will not disperse, and water will converge into a circle under pressure. The principle is caused by the gravity of matter. Is the atomic bomb really powerful? Is the universe really born with such an explosion? My answer is no,

Negative reasons: the accumulation of matter is caused by gravity, which forms stars and objects. No matter how big the matter is, it is impossible to collapse because of its huge size, because the smallest matter cannot overlap, and the size of the object is only the distance change of the smallest matter. The smallest matter is not a molecule, nor an atom, but an electron, and the matter cannot exceed the limit speed, that is, the speed of light. The universe can't be formed by explosion, even if the explosion pushes matter at the speed of light. It is also impossible to calculate that the universe was formed in an instant, and it is impossible for matter to accelerate to the limit speed.

The celestial bodies and planets that are attracted together by gravity to form the universe are consistent with it. Although I can't understand it, I believe that we won't wait until human beings disappear to get the answer.

3. Write a review of the trip to the edge of the universe.

Review of the trip to the edge of the universe-"I" is a star.

The earth where human beings live is just a small world in the infinite universe, as small as dust. However, human beings think that the third place where they live is the whole world, which shows how limited the vision of human beings as "lower creatures" is.

In other words, in the universe, there must be other forms of wisdom besides human beings, but not necessarily in the form of life or the state of stars that we humans generally understand. In other words, the human invisible soul may rise to the universe after leaving the human body, and then continue to exist in the form of stars. There are differences in size in the material world, and there may be no differences in size in the soul world.

Each star governs its own galaxy, and the galaxy is its body. Imagine that I am a star, running in my own orbit and having my own life, but this life is beyond human understanding and is another dimension.

I am a star. What will I face?

First of all, I will face various celestial bodies in my own galaxy, such as planets. I am the source of their life, giving my glory, watching the birth of new planets in my own galaxy and watching all kinds of things happening on them. Perhaps it is my greatest mission to make the planets in my own galaxy produce life. Hehe ~ ~ ~ Sounds like I'm really like a god.

So I thought that the earliest god worshipped by ancient humans was the sun, and all activities of the sun were conscious. It is the conscious behavior of the sun that created everything in the solar system, including all life on earth. The sun is the source of consciousness, the provider of all energy in the solar system, in other words, the creator and God of the solar system.

Of course, stars also have their birth and death. Like life, they also have their own cycles, behaviors, activities and even feelings. Where did the star go after he died? Will it become a creature like human beings to experience an alternative lifestyle?

Hope to adopt

4. The composition of A Journey to the Edge of the Universe

I saw a movie today, the name is Journey to the Edge of the Universe.

This is a gorgeous documentary about popular science in the universe. The image of this film comes from the Hubble Space Telescope. Studying the science and history of distant celestial bodies, this spectacular epic journey of the universe takes us from the earth, to the moon, to neighboring celestial bodies, across the solar system, to the nearest star in the solar system, and then through the nebula, the Milky Way to the farthest edge of the known universe ... Following its pace, my thoughts have already flown out of the Milky Way and wandered in the vast space ... We live on the earth, and whenever I look up at the sky, I am like a movie commentator. Maybe it's evil darkness, maybe it's good light. Faced with endless speculation, the team members got up the courage and started a step-by-step journey of time and space.

The height from the ground 100 km is the edge of the universe, and it takes only one hour's drive to step into the nearest solid-state satellite-"Moon" with an average distance of 390,000 km from the Earth. The moon in the film is like an abandoned battlefield.

We can also clearly see neil armstrong's first footprint on the moon-as clear as stepping on it yesterday. Because the flow of air forms the wind, there is no air on the moon, so there will be no wind. Flying dust is formed because the wind throws fine particles on the ground into the air, so there will be no flying dust on the moon.

Therefore, neil armstrong's footprint will last forever. As for how long it can last, it may be longer than humans. Freya-Venus is called Chang Gung when it appears at night and Qi Ming when it appears in the morning.

A sister star of the earth is similar to the earth in size and gravity, but there is a great danger lurking in its beauty: the dazzling clouds are actually thick clouds composed of deadly concentrated sulfuric acid; The atmosphere is full of more than 97% carbon dioxide; The surface reaches a high temperature of 465 degrees Celsius to 485 degrees Celsius; 90 times the atmospheric pressure of the earth, equivalent to the atmospheric pressure of the 900-meter deep sea of the earth! It is worthy of being a "sister from hell". Thousands of volcanoes are covered with acne, and the high concentration of carbon dioxide retains the heat of the sun. It's burning.

Not only Mars is burning, but also Mercury is burning. Mercury, known as the star in China, is the smallest of the eight planets and the smallest planet in the solar system, but from the video, it is still one third larger than the moon.

It's MINUS 275 degrees at night and more than 800 degrees at noon. Burn it and then freeze it, expose it to the hot sun and then cool it.

Mercury is hard to observe, although it is so clear in the video. Mercury is so close to the sun that it is often submerged by fierce sunlight, so telescopes can rarely observe it carefully.

Mercury has no natural satellites. The only satellite that has ever been close to Mercury is the American probe Mariner 10. When 1974-1975 detected mercury, only about 45% of the surface was captured.

Compared with its size, little mercury has a strong attraction. It is like a big iron ball wrapped in a thin rock layer, with only the inner core and no shell left.

Maybe its outer layer was blown up in a deadly cosmic ball game. The power of the sun can't be confronted and resisted, but its charm has hypnotic magic, which makes obsessed human beings like moths to the fire.

The burning fireball is the sun. Push you slowly and zoom in slowly.

The sun is very big, but how big is it? According to scientists' estimation, the sun is big enough to hold 6.5438+0 million earths. I'm sure you can't imagine these numbers, but their true face in the video is amazing.

It is surrounded by fiery red lines. If you look closely, the red wave formed by hot air is coming towards you. It is incredible that the surface temperature of the sun exceeds 10 thousand and its core temperature can reach tens of millions of degrees.

I don't know what to say to express the temperature I feel. As the movie said, "It is hot enough to convert millions of tons of goods into energy in a few seconds, which exceeds all the energy produced by human beings in history. Nuclear weapons on earth are nothing to him ... "One day, everything in time will end and the fuel of the sun will run out. As the sun dies, so will the earth.

This God created life and will destroy it. So, for the earth, you and I are just a speck of dust.

To the galaxy, the earth is just a speck of dust. To the universe, the Milky Way is just a speck of dust.

For time, the whole universe is just a passing sight. Rumor has it that Mars, Martians, is like Jupiter, a monster.

Saturn is named after the Roman Saturnalia. Billions of stars like the sun, mysterious black holes … scene after scene appeared in front of my eyes.

Entering the mysterious universe is like entering the door of the unknown world, and unexpected magic is waiting for you, the beautiful and vast galaxy! At the end of the film, I saw thick smoke and black characters on a white background, gradually transmitting fiery red light, flashing dazzling silver light, interweaving and rotating, forming a big fireball mixed with red and yellow, flashing strong light around-that is the edge of the universe, gradually drifting away, slowly, bit by bit, the light becomes weaker, the volume becomes smaller, and the distance becomes farther, in the center of the picture, the universe. When I thought everything was going to be calm, it suddenly approached and zoomed in, and the surrounding silver was shining like smoke-the moment of the big bang came, the most violent and creative moment in history! Everything that happened later started from this moment.

Instantly turned into a thick red slurry, flowing, as if looking down from the sky, and gradually declined, from fiery red to brown red and fiery red. Then, a blue-purple ball appeared, gradually dispersing and expanding the surrounding dark purple and dark blue light. Just like the light reflected by Mitsubishi reflector, it immediately covered the fiery red of temptation.

The flow rotates, gradually becomes a color dominated by dark tones, and contracts toward the center, just like a bottomless pit, and the surrounding light seems to be captured by it. Sure enough, with a brush, everything was over, leaving only a tiny purple light.

This is not the end. Look, "An infinitely hot, infinitely small and infinitely tight point exploded ..." Instantly exploded.

5. journey to the edge of the universe is 300 words.

Due to my sudden interest in strange cosmological theories such as black holes, wormholes and singularities, I have recently found a lot of materials to read. By chance, I found this book A Journey to the Edge of the Universe, but I didn't really want to get a gorgeous gift.

Looking up at the stars is almost a habit we have had since childhood. From the story of "there are countless stars in the sky" when I was a child, to the simple and boundless knowledge of the universe accepted in class, and even the students' enthusiastic interest in the constellations all over the sky just because of the Saint of saint seiya, the starry sky grew with us, but we gradually could not look back clearly in the night sky of the city.

From the content, travel is a series of cosmic astronomical knowledge, from the recent human landing on the moon to the review of the solar system, to nebulae, white dwarfs, neutron stars, black holes, and from our milky way to the origin of BIGBANG. No matter who is interested in cosmic astronomy or a novice who is not familiar with it before, you can gain a lot from this film.

I haven't seen many science and education films about the universe, and I dare not say that they are the most gorgeous, but when this "Travel" appeared in front of me, I was really amazing. Exquisite, scientifically based computer animation, the lens is properly switched and the music is in place. The only regret is that there is not enough big screen to enjoy (I remember going to the planetarium to watch the dome projection when I was a child. I really hope this film can also be performed, which is absolutely enjoyable).

If there's anything special about this book, it's his theme cut-in angle. It is based on: family travel. We can stand here and look up at the starry sky forever, or we can set off at once to explore the universe and find another paradise.

Undoubtedly, human beings are small, the earth is small, and even the solar system we are familiar with is just a drop in the bucket of the Milky Way. For the whole universe, there are more than 10 million galaxies like the Milky Way. From a far angle and a bird's eye view, maybe we can realize how fragile and precious our only blue home is in this dark universe.

In addition, the narrator of this film is an actor I like very much: alec baldwin. What? You don't know him? Haven't you seen the first American comedy series "30ROCK"? It is absolutely necessary to make up for it. It's not funny. Come to me and I will tell you ...

6. The review of A Journey to the Edge of the Universe is about 500 words.

A boring but profound question that I thought about when I was very young. What is beyond the earth? After watching the documentary, I suddenly had some new ideas.

It can be simple or complicated to understand, just as the end says, "This is the end of the journey, but it is also the beginning of this journey."

A simple understanding is that you compare the whole universe to a dust, and then infinitely enlarge it to the limit you can think of, for example, it is as big as a stone, and then it is as big as ........................ of the earth, so the edge of the universe is the dust compared before (this dust represents a cosmic polar particle we know in the film) and infinitely enlarge it to the range you can know. This is only a one-way understanding from A to B, and I believe many friends will understand this.

As for the more complicated understanding, my understanding is also limited. Let me briefly talk about my understanding, and please discuss it more. My point is that there is a basic concept that needs to be explained, that is, I don't support that the original formation of the universe was caused by the Big Bang. If this argument holds, what was before the Big Bang? I think the whole universe (including space and time) is put forward to make you better understand the definition of the universe. I don't think the definition of time needs to be converted into the universe. If we have to count the time, then this problem will never be solved, and it is logically unreasonable. Imagine taking time as dust in the above metaphor, that is, one-way understanding from A to B, infinite to the limit, meaningless)) just like a perpetual motion machine.

A few simple words can't express my point of view, but because our human knowledge level is limited (that is, there are too many things that can't be explained clearly), this is a mystery that we can never solve. Do you remember the last paragraph when you say forever? It is both the end and the starting point. Intelligent creatures who are more advanced than us may know the universe better than us. Then go there and sum up my point of view with a well-known sentence, color is empty, and empty is color. (This is the highest realm of Buddhist thought) I don't believe in any religion, but I just think that Buddhist thought has relatively advanced philosophical attainments.

7. After watching Journey to the Edge of the Universe, I was thinking about what is the meaning of people living and why I should live.

This question is wrong. The so-called meaning is only a subjective value judgment, and there is no objective reality. The subject of meaning is me. Without me, there is no point. Without me, it is neither meaningful nor meaningful. Just like when a person is alive, we can judge whether he is kind or vicious. But when he died, he didn't really exist. At this time, we are facing a corpse, which can no longer be evaluated by goodwill or malice.

I exist when I am alive, but not when I am dead. I am the same thing as living. I can only live. The expression "dead me" is a grammatical error, just like a square circle, sad happiness, this malignant corpse, which is just a random combination of words and symbols and does not correspond to any facts.

Label travel universe edge 300-word composition fourth grade landscape composition

In the universe, everyone is full of curiosity. The universe is so big and boundless. There are all kinds of stars and planets in the universe. Of course, our earth is also an asteroid, and the sun is so huge that it can accommodate 6.5438+0 million earths. In the universe, it is dangerous because of beauty. Jupiter's Great Red Spot is the biggest storm in the solar system, at least three times the size of the Earth. This storm has lasted for more than 300 years. Saturn is very distinctive. It's like a giant balloon. Light enough to float on the water. It is a gem in the solar system.

I learned about celestial bodies; White hole, black hole, dark matter, solar system, Milky Way, Kepler -22b, Enceladus. Wait a minute. Red giant stars, galaxy clusters, the attraction of the sun, white holes, black holes and Mars are what I am most curious about.

From it, I know that in another 6 billion years, human beings will end up like dinosaurs. Where did the universe come from? Where do creatures come from? Where do celestial bodies come from? Where did all this come from? Ah! I really want to know!
