The theory of the origin of chemistry "holds that life is native to the planet and evolved from inorganic matter." It divides the origin of life into four stages: first, the stage of generating organic small molecules from inorganic small molecules; second, the generation of biological macromolecules from organic small molecules; thirdly, a multimolecular system is composed from biological macromolecular substances; Fourth, organic multimolecular systems evolved into primitive life.

One of the most important is that the genetic material that can replicate itself, and for now, the only genetic material found on various planets is DNA and RNA. Maybe it's because humans are too lonely and haven't experienced enough planets, or maybe it's a cosmic fact.

Some people will wonder why different planets have the same structure. To better explain this, there is a very famous math game called "Game of Life".

The basic idea of the "game of life" is to give an initial configuration, and then formulate some basic rules to observe the evolution of life, whether there will be a series of similarities.

In the beginning, all the cells were randomly distributed in a large grid of squares, and the rules of evolution were very simple, with only 4 lines.

1. "Too underpopulated": Any living cell that dies if it has less than 2 living neighbors in the vicinity.

2. "Normal": Any living cell continues to be alive if it has 2 or 3 living neighbors.

3. "Overpopulation": Any living cell dies if it has more than 3 living neighbors.

4. "Reproduction": Any dead cell will come alive if it has exactly 3 living neighbors.

Just a few simple rules will evolve into extremely complex dynamic images, and these dynamic images will form very peculiar dynamic laws.

What does that mean?

In other words, through this game, it is explained that some very simple rules can evolve into extremely complex structures, which actually have a lot in common with the birth and reproduction of life.

The craters of each planet, the bottom of the sea, these initial environments are almost the same. The high pressure, as well as the humid and complex environment, provide the same rules for the birth of life.

Under these rules, simple organic matter is randomly combined into complex organic matter.

These complex chemicals, in turn, can further synthesize self-replicating genetic material such as DNA and RNA, thus explaining the universality of life in the universe. It also explains why the creatures we encounter have genetic material.

Even though the types of genetic material vary greatly, they are still genetic material-centric species.

"It's a pity that we haven't found the original DNA and RNA, which is the simplest genetic material that can replicate itself...... Otherwise, the hypothesis will really become a theorem. ”

The discussion was initiated by Professor Yamamoto of Unreal Labs, as well as some geographers who were on the Riley Star expedition.

Zhang Yuan sat below, just an ordinary listener.

He frowned, not knowing what Yamamoto was going to say, so he raised his hand and asked directly, "Professor Yamamoto, time is limited, I want to ask what you mean by the mass extinction of life." Is there any scientific experiment on the Riley civilization without approval? In particular, biological virus experiments ......"

"You know, although our current law doesn't have anything about extraterrestrial civilizations, it's a big loophole. But random biochemical experiments are not morally allowed......"

"Your Excellency, I know, I know, I swear I will not make a mistake in this regard." Yamamoto stood on the stage, a little impatient, probably because there was too much black history, and the people around him had suspicious eyes.

He hurriedly replied: "You listen to me first, it won't take up too much of your time." ”

"One of the examples I just gave is the game of life......"

"There are a total of 256 rules in this game, and under each rule, the final result is different due to different initial conditions. ”

"But the laws that it can form are still limited, namely: the change ends in a constant image, there is a periodic change, the image changes are almost random, and there is a certain complex law in the image."

"If this two-dimensional game is compared to the civilization of a two-dimensional world, can it be understood in this way: change ends in a constant image, which is equivalent to a civilization completely solidified in class, and civilization no longer changes."

"There is a cyclical change, that is, there is a historical cycle, and although the image is dynamic, it no longer progresses. These two categories are all mediocre civilizations according to the historiography of the new civilization. ”

"The near-random change of the image and the existence of some complex law in the image have the possibility of non-banality. Our historiography of the new civilization is precisely to penetrate this kind of complex law......"

"Let's not forget that there are only a few very simple rules that support the operation of the game of life. And we usually believe that the laws that support the operation of the universe should also be concise, can we draw some inspiration from it? ”

Zhang Yuan frowned and thought. Yes, this is just the simplest two-dimensional image, and the real cosmic civilization can be much more complex than a two-dimensional image...... But in some ways, can the individual of a civilization also be compared to a three-dimensional, geometry composed of certain laws?

This is a very novel perspective, and many mathematicians have already lost their minds.

But it's too hard and too hard to really crack these mysteries.

Yamamoto changed his words and continued: "By the way, everyone, this meeting is not about the historiography of new civilizations, but about the spontaneous mass extinction of species that is about to occur on this planet. ”

Mass extinction?

The small number of people at the bottom have just heard about this topic and have come back to their senses.

He didn't sell it, he took out a finger-thick, wood-like thing from a box, and started the experiment on the spot.

"You see, this is the heart of the World Tree, the hardest part. This batch of tree hearts comes from a small 15-year-old tree, which is as tough as steel bar, and without the heart of the tree, the World Tree would not have grown so tall. Rest assured, we have undergone a special sterilization treatment, so you can observe it up close. ”

Zhang Yuan took a small section of the heart of the tree handed over by the staff and broke it vigorously, its hardness was very high, even if he used all the strength of his body, he didn't even bend it at all.

"It's a pretty good material."
