Chapter 77 The Mystery of the Universe

"There are so many things to do..."

Looking at each project, it is obvious that people's living environment is getting closer to the earth. There is artificial sunlight in the sky, greenery on the roadside, and oxygen is produced by plants. Even the pickiest people can feel that the living environment is improving significantly.

Because it is working time now, there are few people on the street. People walking by are in a hurry. Some are thinking, some are smiling, and their expressions are different. Generally speaking, there are mostly positive emotions.

Finally, Yu Yifeng and Roman came to a piece of grass, which is also one of the main contents of environmental transformation.

Seeing this piece of grass, Yu Yifeng suddenly squatted down and stroked the grass in front of him carefully. They are thick and short, bright green, very ordinary, and very solid.

I really miss it... Although it is just the most ordinary loess and the most ordinary grass, and even its scientific name is unknown, these combined together give Yu Yifeng a very intimate feeling.

There is no such lawn in the lunar base. Noah used to have no such lawn, but now... people have finally made it, with soil, lawn, and unknown wild flowers.

Sitting quietly on this lawn, feeling the sun-like light, the breeze blowing slowly around, and a few ants crawling under his feet from time to time... This lazy feeling makes Yu Yifeng have the illusion of returning to Earth.

This is a kind of homesickness...

In Yu Yifeng's hometown, there is such a tradition: wanderers always bring a handful of soil from their hometown when they go out. Whenever they miss their hometown, seeing the soil from their hometown is like seeing their hometown... However, humans now don't even have the ability to take a handful of soil from their hometown.

Only after losing the mother planet do we know how good the mother planet is. Perhaps humans will always be like this, and only after losing it do we know how to cherish it...

After a long time, Yu Yifeng got rid of this homesickness, slowly stood up, and sighed.

Earth, humans can't go back. Humans can only keep moving forward and never retreat!

Roman seemed to empathize with Yu Yifeng, and only then did he come to his senses. "This lawn is the natural park we are about to build. The park is not very large, about 1.2 square kilometers.

We spent a lot of effort to create soil similar to the earth, which has a small ecosystem with insects, small herbivores and small carnivores."

Hearing this data, Yu Yifeng frowned. 1.2 square kilometers? This is not what he wants. According to the plan, this natural park should have lakes, grasslands, trees, and rockery. How can 1.2 square kilometers be enough?

"1.2 square kilometers? Too small, why is it so small?"

"Because... our technology can't make the entire large ecosystem cycle." Dr. Roman shook his head and said, "I plan to try a small ecosystem first, and then try a bigger one."

"Why?" Yu Yifeng asked puzzledly.

"Let's put it this way. Whether it's technology or resources, we don't have enough. If the park is too big, a lot of water will be needed for irrigation every day. We can get about three Qinghai Lakes of water from Mars, which is not much, and we can't waste it at will."

"Besides, the transpiration of plants will release water molecules into the air, but these water molecules will only accumulate in the spacecraft, and will not form clouds or rain like on Earth. So the air humidity will become higher and higher, and the entire spacecraft will be extremely humid. I don't think you want this."

Yu Yifeng nodded. This was something he didn't expect.

"For the problem of humid air, we can only use air dehumidifiers, and by the way, we can recycle some water... Once the park is big, we have to build more dehumidifiers and consume more electricity. I don't think it's necessary."

Yu Yifeng held his chin and understood. Roman meant that small parks are easier to control, and people don't have the conditions and technology to build large parks. He thought too simply. All artificial things are complicated and delicate, just like walking on a tightrope. It can be said that one hair moves the whole body.

Humans have not yet been able to create an ecological environment like the Earth, but a system with automatic adjustment capabilities like the Earth is what biologists dream of. A 1.2 square kilometer park... "Well, let's just leave it at that. It's already pretty good for humans now." Yu Yifeng nodded helplessly.

"We also extracted a lot of air from the Martian atmosphere and sealed and compressed it in other places. In the future, we humans won't have to worry about insufficient carbon dioxide..." Dr. Roman added.

"Oh, by the way." He patted his head and suddenly said, "There is a discussion meeting about the universe this afternoon. I hope you can come and listen."

"Oh? What's the main topic?" Yu Yifeng asked. If it's interesting, of course you can attend. He just happens to be free this afternoon.

"Conjectures about life, civilization, and wisdom. Many biological scientists, physicists, and cosmologists will participate. The content... Well, I think you should listen."

Since Dr. Roman said so, Yu Yifeng immediately nodded in agreement. Humans really know too little about the universe. If scientists have studied something, it is of course a good thing. As a leader of civilization, he should listen.

…

Since the birth of wisdom, humans have begun to explore the universe and explore the mysteries of life and wisdom.

The four ancient civilizations in human history each have their own views.

In China, there has been a saying since ancient times that the sky is round and the earth is square, and its essence comes from the evolution of the innate Bagua.

Other ancient civilizations also have similar views: the ancient Egyptians, who lived along the Nile River and had a long and narrow terrain, believed that the universe was like a long box from north to south, that the earth was floating on the water, and that the sun, moon, and stars were all hung on the roof, supported by divine power...

The Babylonians believed that the sky was like a dome covering the earth, and that the sun, moon, and stars each had life and moved on the dome.

The ancient Indians believed that the earth was carried on the backs of four elephants...

These views are strange, and they are all conclusions drawn by people based on the phenomena they saw in front of them and then boldly guessed.

It was not until the 4th century BC that the ancient Greek philosopher Aristotle proposed the slightly more reliable "geocentric theory".

Then, in 1543, Copernicus proposed the more accurate "heliocentric theory". Copernicus believed that the sun was at the center of the universe, and the earth and other planets orbited the sun along circular orbits.

It can be said that human discovery and exploration of the universe is a process of continuous error correction and continuous improvement...

Modern science believes that the sun is just an ordinary star in the Milky Way. The Milky Way is just an ordinary river system in the vast universe. Even the "heliocentric theory" has been denied.

Then, what else do people know? Perhaps, the cognition of modern science is still wrong...

Tiny humans have never discovered alien life, not even a shadow. The only discovery is the Noah spacecraft, but alien life has not been found. Where did they go? No one knows...

In the year after the earth exploded, people had to step into the starry sky, and they found alien life on Mars!

Although it is just some viruses that are not even as good as prokaryotic cells. But what does this mean, and what can people interpret from it?

"This is the main purpose of this scientific discussion. We want to gather everyone's wisdom to explore the life, wisdom and civilization of the entire universe." A female scientist took the lead in the meeting.

The initiators of this discussion are astronomer Professor Thomson, biologist Dr. Roman, and a female astronomer named Hegel, who is the host of this session.

Yu Yifeng sat below, just an ordinary audience.

Many scientists present looked serious, and Yu Yifeng even read a sense of discomfort. Obviously, the discovery of the Martian virus is not a good thing for humans.

Hasn't the Martian virus been conquered by humans? It is said that even the gene sequencing results are about to come out. Why is it not a good thing? He was just a little puzzled.
