In the cosmic void of the solar system, there is a very tiny "ant" slowly crawling towards the periphery of the solar system, this "ant" is the "ocean" spaceship, although it is the largest spaceship made by human beings now, but not to mention compared with the vast cosmic starry sky, even if it is placed in the entire solar system, it is already an ant to lift it.

The universe is so vast that even the solar system of asteroids, even the distance between Earth and Mars, is only 0.52 astronomical units on average, which is nearly 80 million kilometers in kilometers.

In such a vast area, although the speed of the "Ocean-Going" spacecraft has reached a speed of nearly 100 kilometers per second, it still takes nearly 10 days to fly from the Earth's orbit to the Martian orbit, and if you consider acceleration and deceleration, it will take half a month to go to Mars alone.

Therefore, although the speed of the spaceship is very fast at this time, the feeling to everyone on the spacecraft is that the spacecraft has always seemed to be standing still, especially the scenery outside the spaceship is almost unchanged, and the stars in the dark void are dotted with stars, even if the 8 planets in the same solar system are not visible at all.

Originally, I was able to see the earth just a few days after departure, but now, the figure of the earth has long disappeared into the void, and it is necessary to use an astronomical telescope to see the earth, and it is still impossible to distinguish the earth with the naked eye.

The rest area in the "Ocean Ocean" spacecraft, which is full of all kinds of green plants, is a place that everyone likes to come to, and the same is true for Li Fu, Liu Shiying, and Liu Yi at this time, while drinking tea and chatting, of course, in space, because there is no gravity, drinking tea and chatting is also different from the ground.

The three of them don't have to sit at all, of course, they don't need to sit, because they are all light and fluttering, as for the tea, it is a special appliance, a bit similar to a drinking kettle, just press the button on it gently, and the water in the teapot can come out.

Next to the three of them, Li Quanjiang waited respectfully, whose teapot ran out of water, he immediately ran to help add water and change tea.

"I used to think that space travel should be quite interesting, but now it seems to be very boring, this spacecraft relies on inertia to fly, and there is no need to pay attention to anything, we are idle every day, and there is no way to do research, it is really a bit boring."

Liu Yi looked at the unchanged scenery outside the window, took a sip of tea gently, and said a little boringly.

"Space travel is like this, but we now know too little, too little about the universe, how vast, how vast, it is really desirable, there are too many, too many unknowns waiting for us to discover."

Liu Shiying looked at the dark void outside with a fascinated face, as if he wanted to see the other side of the starlight and explore the unknown world.

"The universe is too vast, and we human beings have only just stepped out of the earth, and 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 long understood the vastness and immensity of the universe, and also knows the vastness of the universe, full of infinite yearning, but now human science and technology are still too primitive and backward, and there is no way to move freely in the solar system, how can he be qualified to talk about the universe and the starry sky.

"Do you think there really will be an alien civilization?"

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

"The earth can give birth to life, why can't other planets give birth to life?"

Li Fu didn't answer directly, this time Liu Yi followed, the purpose was to find extraterrestrial life, and to pursue a question that has been debated by human beings for a long time, whether there are aliens.

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

In addition, human beings have never encountered any extraterrestrial life, not even talking to each other, etc., so there are many people who insist that the earth is unique and that humans are unique.

However, there are also many people who believe that the universe is too vast and vast, and the earth can never be unique, and there will definitely be other extraterrestrial life, extraterrestrial civilizations, and the reason why they have not been connected with any extraterrestrial civilization until now is because the universe is too vast, and it is too difficult to connect with each other.

It's like in ancient times, when there were no advanced means of transportation, Asians, Americans, Australians, Africans, Europeans, etc., on the earth, who were too far away from each other, all thought that they were the center of the world, and they were not clear about other places, and even thought that they were wild places.

Asia, Europe and Africa, which are connected by land, are more or less connected with each other, and they can know each other's existence to some extent, but the Australian continent and the American continent, which are separated by the ocean, were even blank on the world map before the great discovery of the Great Voyage, and they did not know that there were vast continents and a prosperous civilized world here.

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

The two points of view have been arguing endlessly, and each side insists on their own views, of course, that the earth is unique in the universe, and that human beings are the only civilization in the universe, which seems to be a bit of a frog at the bottom of the well, and the arrogance of the night.

Because although the history of mankind has been very long, and human civilization has a history of several thousands, the great development of real science and technology is only a few hundred years old, and human beings' understanding of the universe is still very shallow and superficial, and the universe they see 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 like this, only so big, sitting in a well and watching the sky, those who know it are only inferior to the skin.

Such a point of view may be more out of worry and worry about the future, holding a more pessimistic attitude, because the earth civilization is really very primitive now, if there are really countless civilizations in the universe, whether they are stronger than the earthlings, how will they treat the earthlings, 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, and once anything was brought to the universe, it would be very small and ridiculous compared to the vast universe.

"Maybe, hopefully this time something will be discovered, and if extraterrestrial life can be found on other planets in the solar system, even if it is very simple and primitive, I think it will be enough to be one of the most significant discoveries of this century."

Liu Yi nodded undeniably, as a top scientist in the field of biological science, Liu Yi really wanted to know some information about the origin of life and extraterrestrial life, so this time he would follow the "Ocean" spacecraft to conduct scientific expeditions in the solar system.

"It's not that life on Earth, in fact, it's extraterrestrial meteorites brought to Earth from outside the sky, and I think there will definitely be some discoveries."

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

"There have always been two views on the origin of life: one is the idealistic view, which holds that life and all things were created by the so-called God; Another materialist view has emerged with the continuous development of modern science and technology, which holds that life on Earth is created by accident by extraterrestrial meteorites or chemical reactions on the earth itself. ”

"Let's not talk about the idealistic viewpoint, the micro viewpoint is deduced according to the existing biological science and technology, especially Darwin's theory of evolution, coupled with the emergence of genetic technology, almost all organisms can trace the original and simplest life if they go to the source and explore."

"So now scientists basically believe that life is a chemical, physical and other comprehensive reactions, different molecules interact with each other, mix to produce the original organic molecule with DNA, DNA has two qualities: first, it can make amino acids, second, it can replicate itself, DNA these two characteristics are also the basic characteristics of organic organisms like bacteria, and bacteria are the simplest life in life, and it is also the oldest fossil we can find."

When it comes to the origin of life, Liu Yi suddenly came to the spirit, as a top scientist in biology, he has also been thinking hard about the very serious issue of the origin of life.

However, the history of the earth has been billions of years, and the history of life is also very long, and what happened in the long years calculated in hundreds of millions of years can only be studied and inferred through some fossils in modern times, but it is very difficult to trace the source.

Although life is also composed of various molecules, and all kinds of things in the body of life are dead when taken out alone, when they are put together, they are life, which is very magical!

You can imagine that these substances in the human body are very common in nature, but after the combination, man, this amazing life is born.

……

The "Ocean-going spacecraft" flew quietly in the void, getting closer and closer to its first stop, Mars, and in the field of vision, Mars slowly showed its mysterious face to the world.

PS: It is said that on February 14, 1178 AD, that is, more than 900 years ago today, Wu Dalang was poisoned by Pan Jinlian with poison, haha I wish everyone a happy Valentine's Day!
