Chapter 35: The Mystery of the Universe

"There's a lot going on ..."

Looking at one project after another, it is obvious that people's living environment is moving closer to the earth, with artificial sunlight in the sky, greenery on the roadside, and oxygen produced by plants. Even the most discerning people can feel that the living environment is improving dramatically.

Because it is now working hours, few people on the street, one by one is also walking in a hurry, some in contemplation, some in the smile, different demeanor, the overall or more positive emotions.

Finally, Oliver and Roman two people came to a piece of grass, which is also one of the main elements of environmental transformation.

Seeing this piece of grass, Oliver suddenly squatted down and delicately stroked the small grass in front of him. They were thick and short, bright green and bright green, very ordinary and solid.

Really miss ah ... although only the most common yellow soil, the most common grass, and even its scientific name is not known, but these combined, but Oliver brought a very intimate feeling.

The moon base is no such lawn. Once the Noah, also no such lawn, now ... people finally did, with soil, lawn, and unknown wildflowers.

Sitting quietly on this lawn, feeling the general light of the sun, surrounded by a gentle breeze, from time to time crawling under the feet of a few ants ... this lazy feeling, so Oliver has an illusion of returning to Earth.

This is a kind of homesickness ah ...

In Oliver's hometown, there is a tradition that when a wanderer goes away, he always brings a handful of dirt from his hometown. Whenever one misses one's hometown, seeing hometown dirt is like seeing one's hometown ... However, humans nowadays do not even have the ability to take a handful of hometown dirt.

It is only when you lose your home planet that you know how good it really is. Perhaps humans will always be like this, only know how to cherish it after losing it ...

After a while, Oliver got rid of this is homesickness, slowly stood up, a light sigh.

Earth, humans are not going back. Humans can only keep moving forward, never backward!

Roman seems to empathize with Oliver, and only then also came back to his senses. "This lawn is the nature park we are about to build. The park is not very big, about 1.2 square kilometers.

We went to a lot of trouble to create earth-like soil with a small ecosystem of insects, small herbivores, and small carnivores."

Oliver's brow furrowed when he heard this figure. 1.2 square kilometers? This was not what he wanted. According to the plan, this nature park should have lakes, grass, trees, rockery, how can 1.2 square kilometers be able to?

"1.2 square kilometers? It's too small, right? Why so small?"

"Because ... our technology can't make the whole big ecological cycle yet." Dr. Roman shook his head, "I'm going to get a small ecosystem to try first, and then try something bigger."

"Why?" Oliver queried.

"Let's put it this way, we don't have enough, both in terms of technology and resources. If the park is too big, the amount of water needed to irrigate it every day is a lot. We can obtain about three Qinghai Lakes of water from Mars, which is not much to waste freely."

"Besides, the transpiration of plants will emit water molecules into the air, but they will only pile up in the spaceship and will not form clouds or rainfall like on Earth. So the air humidity will get bigger and bigger, and then the whole ship will be abnormally humid, and I don't think you want that."

Oliver nodded, this is what he did not expect.

"For the problem of air humidity, you can only use air dehumidifiers, by the way, you can also recycle part of the water ... park once it is big, you have to build more dehumidifiers and consume more electricity, I think there is no need for that."

Oliver held his chin to understand, Roman means that small parks are better controlled, people do not have the conditions and technology to build large parks. Is he think too simple, all artificial to build something, are complex and delicate, like walking a tightrope, can be said to involve a hair and move the whole body.

Earth like ecological environment, humans have not been able to build, but like the Earth has the ability to self-regulate the system, is what biologists dream of. 1.2 square kilometers of park ... "Alas, so be it, for the current human, is already considered good. " Oliver nodded helplessly.

"We also took a large amount of air from the atmosphere of Mars, sealed and compressed elsewhere, so we humans won't have to worry about not having enough carbon dioxide in the future ...," Dr. Roman added.

"Oh, right." He tapped his head and suddenly said, "There is a discussion session about the universe this afternoon, I hope you can come and listen to it."

"Oh? What's the main talk?" Oliver asked, if it was more interesting, of course he could attend it, he just had time this afternoon.

"Speculations about life, civilization, and intelligence. Many biological scientists, physicists, cosmologists will attend, the content ... alas, I think you should listen to it."

Since Dr. Roman has said so, Oliver immediately nodded his head to agree. Humans really know too little about the universe, and if the scientists have researched something, it is certainly a good thing that he, as the leader of civilization, should listen.

...

Humans, since the moment of the birth of intelligence, began to explore the universe and explore the mysteries of life and wisdom from it.

The four ancient civilizations of human history, each with its own point of view.

In China, since ancient times there has been the saying that the sky is round and the earth is round, the essence of which originates from the evolution of the eight trigrams of the first heaven.

Other ancient civilizations had similar views: the ancient Egyptians, living along the Nile River, had a long and narrow topography throughout the region, and believed that the universe was like a longer box from north to south, the earth was floating on water, and the sun, moon and stars were hanging from the top of the lid, supported by divine power ...

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

And the ancient Indians believed that the earth was carried by four elephants on their backs ...

These views are strange and strange, are people with the phenomenon seen in front of their eyes, and then boldly conjecture the conclusion.

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

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

It can be said that mankind's discovery and exploration of the universe is a process of constant correction and improvement ...

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

And then, what else do people know? Perhaps, the modern scientific perception is still wrong ...

The small human race, once - never found alien life, not even a little shadow has seen. The only discovery was the Noah spacecraft, but what about extraterrestrial life, not found, where did they go? No one knows ...

In the year after the explosion of the Earth, people had to step into the stars, and it turned out that alien life was found on Mars!

Although it was just some virus that wasn't even a prokaryotic cell. But what does this mean, and what can one decipher from it?

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

The initiators of this exploration were Professor Thomson, an astronomer, Dr. Roman, a biologist, and a female astronomer named Hagel, who was the moderator of this session.

Oliver sat down, just a general audience.

Many of the scientists in the audience looked serious, and Oliver even tasted a not-so-comfortable implication. It was clear that the discovery of the Martian virus was not a good thing for humanity.

Wasn't the Martian virus conquered by humans? It is said that even the results of genetic sequencing are almost ready. Why is it still not a good thing? He was just a little puzzled.
