"Most of these things are related to people, and they must have something to do with the nature of your work. Wu Lang smiled slightly.

Xin Ying's eyes showed a look of admiration, and said with a smile: "Professor Li said that you have a very high level of understanding, excellent intelligence, and you are the only one in your life, I was a little skeptical at first when I heard it, but now it seems that what you said is true, it is better to meet than to be famous!"

Wu Lang raised his head again and drank a small bottle of Erguotou, took a deep puff of cigarette, and said, "What else do you want to say, please continue, I will listen." ”

Xin Ying chuckled: "Since human beings have consciousness, the concept of "eternal life" has been entangled and tormented people like a nightmare, because everyone knows what death means for a life, so eternal life, which is the opposite of death, has become one of the biggest fantasies in many people's lives, in fact, when it comes to "eternal life", we have to mention "death" first After a long period of observation and study of a large number of samples, scientists have found that if you follow the psychological development process of a normal person, there are three stages in a person's life, and there will be a very obvious fear of death. ”

Wu Lang smiled: "I really don't know this, Teacher Xin, can you tell the students specifically, what are the three stages?"

After Xin Ying listened to Wu Lang's words, she glanced at him coquettishly, nodded and smiled: "Okay, listen to the teacher slowly tell you, the first stage is the early childhood period of about 7-10 years old, and the children at this stage have learned the true meaning of death after learning in school and being exposed to the surrounding environment, so in this world full of family, friendship, and colorful contrast, they can intuitively feel the horror of death, so as to have a fear of death." The second stage is the youth period of 18-25, when young people at this age will see the inevitable death in the future again from the illusion of "losing each other" and "losing themselves", and this psychology as a subconscious can play a certain degree of positive significance for people to begin to cherish their current emotions and lives. In the third stage, after the age of 60-80, people in this period will begin to look back on their lives, and most people, because of their age, will have a desire for life and a fear of death. In short, no matter what stage you are in, if you have ever had the fear of death in your heart, you must have thought: how good it would be if there was some way to achieve eternal life, or at least extend life to an astronomical length!"

Wu Lang Zhengse said: "Teacher Xin is very right, wait for the students to find a pen and paper to record it." With that, he got up from the couch and looked around.

"Hahaha"......

Xin Ying pulled him to sit down, laughed for a long time, and then looked directly at him and said, "Look at the way you are dead, Professor Li said that your memory is also the only thing in your life, if you don't want to listen, then I won't say it." ”

"Of course you have to listen, I'm not afraid that Sister Xin will say that you are tired, so let's liven up the atmosphere. Wu Lang hurriedly nodded and smiled.

Xin Ying glared at him, and then said: "Indeed, if people's life expectancy can be increased several times on this basis, throwing away the impact on the environment, then almost everyone will feel fulfilled and happy, because in this way, there will be enough time to achieve, every wish in life, and the goals of work and career, may also become less unattainable, and the most important thing is that the gap between the rich and the poor may also become, not so obvious, because there is enough time to change their lives." But from a higher perspective, eternal life becomes intriguing, because from our current point of view, eternal life can definitely be regarded as a good thing, but why didn't nature give us eternal life? Or why didn't living things evolve the property of immortality? After all, from the perspective of our universe as a whole, it has a history of 13.8 billion years, a range of more than 90 billion light years, and it is only its "true body" is only one in 25 million, and the extension of the life span of the earth's life will not cause much damage to it. On the contrary, according to normal people's thinking, this kind of extension can allow a person to learn more knowledge and skills within the time limit of life, and achieve the goal of life that he wants to achieve to a more sophisticated height, which is also of great benefit to the development of a species or civilization in general, why does nature prohibit this possibility?"

Wu Lang unscrewed a bottle of Erguo again, drank it in one gulp, lit a cigarette, took a deep breath, and looked at Xin Ying.

Xin Ying also lowered her head and took a sip of tea, and continued: "In fact, eternal life is not as simple as ordinary people imagine, nor is it as beautiful as imagined, and the most important thing is that the universe itself is not eternal, whether it is the cosmology depicted by the Big Bang theory or string theory, they all have one thing in common, that is, they cycle between the beginning and the end. Under the control of this law, all things in the universe are natural, and it is impossible to achieve immortality in the true sense, for example, although the lighthouse jellyfish has something similar to the "immortality gene", which can change back and forth between young and old, but after research by scientists, this change is still the upper limit of the number of times, and the essence of the "immortality gene" is not immortality, but the extension of life. From the perspective of species, the replacement of individuals is more conducive to the evolutionary survival of the species itself. And immortality is extremely detrimental to the survival and reproduction of a population, because immortality means "unchanging", a race that cannot change its own genes to adapt to the environment, and the results can be imagined. In fact, we human beings have now developed to the point of "realizing and wanting to pursue eternal life" by relying on science and technology, in fact, we have reached the stage of fighting against nature itself, so is it possible for human beings to greatly extend their life or immortality with the help of science and technology in the future? In fact, there have been breakthrough discoveries in extending life, because scientists have found in the chromosomes that the key to controlling human lifespan - telomeres. ”

"I really don't know this, what are telomeres?" Wu Lang said curiously.

Xin Ying couldn't help but smile: "Yo, there are still things you don't know?"

Wu Lang gritted his teeth and said: "Sister Xin, look at what you said, I am not an immortal, how can I know everything? Even if I am an immortal, it is impossible to know everything, I can do everything, right?"

Xin Ying nodded and said: "Theoretically, as long as you find a way to control the length of telomeres, human life expectancy can be greatly extended, and it is even possible to achieve immortality, but so far, the method of controlling telomeres has not been found In recent years, with the continuous development of quantum technology and computer science, scientists have gradually realized that life and consciousness do not necessarily depend on the body. Personality and state of consciousness are all copied into the computer, you can achieve an alternative kind of immortality, that is, digital immortality, some people may think that this idea, a little amazing or even fantastical, but this is not impossible to achieve, because physicists have proved that human consciousness is a quantum level of activity, and it is precisely because of quantum randomness, human consciousness will also have a high degree of freedom, and non-pre-designed properties, so with the continuous development of quantum computers, one day this idea can be realized. In fact, the digitization of life is not only the benefit of "eternal life", if the digital life and robots are combined, it will be the best "space explorer", because only their infinite life and body that will not get sick can overcome the universe, the huge distance scale, and let human civilization bloom in the universe. ”
