Wandering Spaceship in Deep Space Chapter 374: Organic polymer materials that cannot be decomposed

　　"The theory of chemical origin" believes 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 small organic molecules from small inorganic molecules; second, generating biological macromolecular substances from small organic molecules; third, forming multi-molecules from biological macromolecular substances System; Fourth, the organic multi-molecular system evolves into primitive life.

　　The most important point is that genetic material that can replicate itself is currently the only genetic material found on various planets. Perhaps human beings are too ignorant and have not experienced enough planets, or perhaps this is already a fact of the universe.

　　Some people find it incredible, why do different planets have substances with the same structure? In order to better explain this, there is a very famous math game called "Game of Life".

The basic idea of ​​　　 "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.

　　 At the beginning, all the cells were randomly distributed in a large grid, and the evolution rules were very simple, with only four short ones.

　　1, "Underpopulation": Any living cell, if there are less than 2 living neighbors in the surrounding area, it will die.

　　2, "Normal": If any living cell has 2 or 3 living neighbors, it will continue to live.

　　3, "Overpopulation": Any living cell will die if it has more than 3 living neighbors.

　　4, "Reproduction": If any dead cell has exactly 3 living neighbors, it will survive.

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

What does 　　 mean?

　　 That is to say, through this game, it is explained that some very simple rules can evolve extremely complex structures. In fact, there are many things in common with the birth and reproduction of life.

　　The craters and seabeds of each planet are almost the same in their initial environment. The complex environment of high pressure and humidity provides the same rules for the birth of life.

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

　　 These complex chemical substances can further synthesize other self-replicating genetic material, which explains the universality of life in the universe. It also explains why all the organisms that humans encounter have genetic material.

　　Even though the types of genetic material are quite different, they are still genetic material-centric species.

　　 "Unfortunately, we have not found the original, that is, the simplest, self-replicating genetic material... Otherwise, this hypothesis will truly become the theorem."

　　Professor Yamamoto from Unreal Lab and some geographers who are in the scientific expedition of Riley Star initiated this discussion.

　　 Zhang Yuan sat down, 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 said about the mass extinction. . Is there any scientific experiment on the Riley civilization without approval? Especially biological virus experiment..."

　　 "You have to know that although our current laws do not contain any content about alien civilization, this is a big loophole. However, random biochemical experiments are not morally permitted..."

　　 "Your Captain, I know, I know, I swear I will never make this mistake." Yamamoto stood on the stage, rather impatient, probably because there is too much black history and people around him Doubtful glances came.

　　 He quickly replied: "Listen to me first, it won't take up too much of your time."

　　"I just gave an example, the game of life..."

　　 Various patterns about the "Game of Life" are displayed on the screen. "There are 256 rules in this game. Under each rule, due to different initial conditions, the final result is different."

　　"But the laws that it can form are still limited. They are: change ends in a constant image, periodic changes occur, image changes are almost random, and images have certain complex laws."

　　"If you compare this two-dimensional game to a civilization in a two-dimensional world, can you understand it like this: change ends in a constant image, which is equivalent to a complete class solidification of a civilization, and civilization no longer changes."

　　"There are periodic changes, that is, the phenomenon of historical reincarnation. Although it is a dynamic image, there is no progress. These two categories are all mediocre civilizations considered by the history of new civilizations."

　　 "Image changes are almost random, and images have certain complex laws. These two situations have the possibility of being non-banal. Our new civilization history wants to penetrate this kind of complex laws..."

　　" Don’t forget, that what supports the operation of the game of life is just a few very simple rules. And we usually believe that the rules that support the operation of the universe~IndoMTL.com~ should also be concise, is it possible to learn from it? What about some inspiration?"

　　 Zhang Yuan frowned and thought. Yes, this is just the simplest two-dimensional image. The real cosmic civilization is much more complicated than a two-dimensional image... But in some respects, can a civilized individual be compared to a three-dimensional image, composed of a certain law What about the geometry?

　　 This is a very new perspective. Many mathematicians have fallen into contemplation.

　　 But it is too difficult to really crack these mysteries.

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

　　 species extinction?

A small number of people under 　　 have just heard about this topic, and they have come back to their senses.

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

　　"Look, this is the core of the World Tree, which is the hardest part. This batch of tree cores comes from a 15-year-old tree, which is as tough as steel. If there is no core, the World Tree It’s impossible to grow so tall. Don’t worry, we have gone through a special sterilization process, so you can observe it up close."

　　 Zhang Yuan took a small section of the tree's heart handed by the staff and broke it vigorously. The hardness is very high, even if all the strength of the whole body is exhausted, there is no bending at all.

　　"It's really good material."
