cosmic hegemony

Chapter 203, about life

In the cosmic void of the solar system, there is a very tiny "ant" slowly crawling towards the outer reaches of the solar system. This "ant" is exactly the "Ocean" spacecraft, although it is the largest human-made Even if it is placed in the entire solar system, saying that it is an ant is already exalting it, let alone comparing it with the vast universe and starry sky.

The universe is too vast. Even the solar system of asteroids, even the distance from the earth to Mars, is only 0.52 astronomical units on average, which is nearly 8000 million kilometers in kilometers.

In such a vast area, although the speed of the "Ocean" spacecraft has reached nearly 100 kilometers per second, it still takes nearly 10 days to fly from Earth orbit to Mars orbit. When slowing down, it would take half a month just to get to Mars.

So even though the speed of the spaceship is very fast at this time, everyone on the spaceship feels that the spaceship seems to be standing still, especially the scenery outside the spaceship is almost unchanged, and there are stars in the dark void. The 8 planets in the solar system are also invisible at all.

In the past, the earth could be seen only a few days after departure, but now, the figure of the earth has long since disappeared into the void, and the earth can only be seen with an astronomical telescope, and the earth cannot be distinguished with the naked eye alone.

The rest area in the "Ocean" spacecraft is full of various green plants, and it is a place that everyone likes to come to. At this time, Li Fu, Liu Shiying, and Liu Yi are also the same, drinking tea, While chatting, of course in space, because there is no gravity, so drinking tea and chatting is also different from the ground.

The three of them don't need to sit at all, and of course they don't need to sit, because they are all light and fluffy. As for the tea, it is a special utensil, a bit similar to a drinking pot. You only need to press the button on it lightly, and the water in the tea pot will You can come out, holding a teapot like this in your hand, and take a sip from time to time.

Next to the three of them, Li Quanjiang waited respectfully. If anyone's teapot ran out of water, he immediately rushed to help add water and change tea.

"At first I thought that space travel should be very interesting, but now it seems very boring. This spaceship flies by inertia, and there is no need to pay attention to it. We are idle every day and have no way to do research. It is really boring. "

Liu Yi looked at the unchanging scenery outside the window, took a sip of tea lightly, and said boringly.

"Cosmic travel is like this, but we know too little or too little about the universe now. The vastness and vastness of the universe is really yearning. There are too many, too many unknowns waiting for us. Discover."

Liu Shiying looked at the dark void outside with fascination, as if he wanted to see the other side of the stars and explore the unknown worlds.

"The universe is too vast, and our human beings have just stepped out of the earth. There is still a long, long way to go in the future."

Li Fu also nodded. From the seeds of super civilization, Li Fu has already understood the vastness and infinity of the universe. He also knows the vastness of the universe and is full of infinite yearning. It's just that human technology is still too primitive and backward. Well, there is no way to move freely even in the solar system, so how can I have the right to talk about the universe and the starry sky.

"Do you think there will really be alien civilizations?"

Liu Yi seemed to have thought of something, and asked very seriously.

"Earth can breed life, why can't other planets breed life?"

Li Fu did not answer directly. This time Liu Yi followed him to find extraterrestrial life, and to pursue a question that human beings have been debating for a long time, whether there are aliens or not.

Many people have always believed that there are no aliens, because the birth of life on the earth itself is a miracle. There are too many, too many factors that gave birth to the current earth and this cradle of life. There are endless stars and planets, but the probability of birth of life is too low.

Moreover, human beings have never encountered any alien life, even if they have a dialogue with each other, so there are many people who insist that the earth is unique and human beings are unique.

However, there are also many people who believe that the universe is too vast, and the earth is absolutely impossible to be unique. There must be other alien life and alien civilizations. The reason why they have not yet contacted any alien civilizations , that is because the universe is too vast, and it is too difficult to connect with each other.

It’s as if in ancient times, there were no advanced means of transportation, Asians, Americans, Australians, Africans, Europeans, etc., were too far apart from each other, and they all thought that they were the center of the world. The place is unclear, and even thought it was a wild place.

Asia, Europe and Africa, which are connected by land, are okay. They are more or less connected with each other, and they can more or less know the existence of each other. However, the Australian continent and the American continent separated by the ocean, before the great voyage and discovery, these locations were on the world map. There is even a blank side on the Internet, and they have no idea that there is a vast continent and a prosperous civilized world here.

So although the earth is very special, there must be countless civilizations in the vast universe and starry sky, and countless prosperous worlds are waiting for human beings to explore and discover.

The two viewpoints have been arguing for a long time, and they both insist on their own viewpoints. Of course, they believe that the earth is unique in the universe, and that human beings are the only civilization in the universe. Relatively speaking, such viewpoints seem a bit arrogant.

Because although the history of human beings has been long, and human civilization has a history of thousands of years, the real great development of science and technology is only a few hundred years away, and human beings' understanding of the universe is still very shallow and superficial, so The universe of viewing is very, very small.

Isn't it just like a frog sitting at the bottom of a well looking at the sky, thinking that the universe is just like this, only so big, and sitting in a well looking at the sky, those who know it are not even as good as the skin.

Such a point of view is more likely to be out of worry and worry about the future, and to take a pessimistic attitude, because the earth civilization is really primitive now. If there are really countless civilizations in the universe, are they more advanced than the earth people? Powerful, how will it treat the people on Earth, etc., there are too many, too many things worth thinking about.

"The universe is too vast, and we know too little, too little."

Liu Shiying also nodded, the more he knew about the universe, the more he was in awe of the universe. Once anything was taken into the universe, it would appear very small and ridiculous compared with the vast universe.

"Maybe so. I hope that this time we can discover something. If extraterrestrial life can be found on other planets in the solar system, even if it is very simple and primitive life, I think it will be enough to become one of the most important discoveries of this century."

Liu Yi nodded irresistibly. As a top scientist in the field of biological sciences, Liu Yi really wants to know some information about the origin of life and extraterrestrial life, so this time he will follow the "Ocean" spacecraft together in the solar system conduct scientific investigations.

"It's not that life on Earth is actually brought to Earth from extraterrestrial meteorites. I think there will definitely be some discoveries."

Liu Shiying doesn't know much about biotechnology, so he said it casually.

"Regarding the origin of life, there have always been two views. One is the idealistic view, which believes that life and everything are created by the so-called gods; the other materialistic view is that with the continuous development of modern technology It is believed that life on earth was accidentally produced by extraterrestrial meteorites or chemical reactions on the earth itself."

"Not to mention the idealistic point of view, the microscopic point of view is based on the deduction of existing biological science and technology, especially Darwin's theory of evolution, coupled with the emergence of genetic technology, almost all creatures can go to the source if they seek and explore. It can be traced to the most primitive and simple life."

"So now scientists basically think that life is a comprehensive reaction of chemistry, physics, etc. Different molecules interact and mix to produce primitive organic molecules with DNA. DNA has two characteristics: first, it can produce amino acids, Second, it can replicate itself, and the two qualities of DNA are also the basic characteristics of bacteria-like organisms, and bacteria are the simplest life forms in the world of life, and they are also the oldest fossils we can find so far."

When it comes to the origin of life, Liu Yi immediately became energetic. As a top scientist in biology, he has been thinking hard about the very serious issue of the origin of life.

However, the history of the earth has been several billion years, and the history of life is also very long. What happened in the long years calculated in hundreds of millions of years can only be studied and deduced through some fossils in modern times, but if you want to It is very difficult to trace the source.

Although life is also composed of various molecules, all kinds of things in the living body are dead when taken out alone, but when they are combined together, they are life, which is very miraculous!
You can imagine that these substances in the human body are very common in nature, but after the combination, human beings, this magical life, are born.

……

The "Ocean" spacecraft is flying quietly in the void, getting closer and closer to its first stop, Mars. In the field of vision, Mars slowly shows its mysterious face to the world.

PS: It is said that on February 1178, 2 AD, which is more than 14 years ago today, Wu Dalang was poisoned to death by Pan Jinlian. Haha I wish everyone a happy Valentine's Day!
