Is it possible to realize the human hibernation technology in "The Three-Body Problem" and "The Wandering Earth 2"?

Release time:



"The Wandering Earth 2" is a hit, and when it comes to The Wandering Earth, we have to mention "The Three-Body Problem", which won the Hugo Award.

Not long ago, the TV series "The Three-Body Problem" represented Chinese science fiction going abroad. In just a few months, it received a high score of 8.0 on IMDB. We have to say that "The Three-Body Problem" is a very good TV series. It not only It has shown a high level of technology, and has also achieved great success in character creation and plot arrangement. It has been mentioned many times that humans will use technologies such as "hibernation" to deal with future attacks by alien civilizations and explore the mysteries of the universe.



1. Hibernation technology in science fiction works

When interstellar travel becomes possible, hibernation machines may become standard equipment on spacecrafts, which will also provide technical support for long interstellar exploration manned missions.

Most descriptions of hibernation technology in science fiction works involve astronauts being cooled during hibernation. Various sensors will be connected to their bodies to monitor their physical conditions and absorb parenteral nutrients (TPN) through intravenous injections. These liquid nutrients contain all the necessary nutrients for the normal functioning of the body. Additionally, a catheter will be inserted into the urethra for urination. Since no solid food is consumed, the human digestive system will be inactive. Electromagnetic muscle stimulation will protect key muscle tissues of the human body and avoid muscular dystrophy.

2. Application of low-temperature biomedical technology in reality


As a highly evolved warm-blooded animal, can the human body really achieve hibernation? This question has been answered through the development of cryogenic technology. Hypothermia has been introduced in the field of medical research to treat neonatal encephalopathy, brain trauma, and spinal cord injury. Lowering the patient's body temperature helps reduce ischemic damage to body tissues in a state of insufficient blood flow. To date, medically induced hypothermia has been used only in critically ill patient care.

Human dormancy is also used in clinical surgical operations to carry out key organ transplants and critical operations. During the operation, pre-cooled saline and various measures are used to reduce the body temperature to 18°C or even lower (such as 10°C and below), causing the patient to enter a dormant state. At this time, the patient basically has no pulse, blood pressure and brain waves. The advantage of this is to reduce the metabolic rate of the body's tissues and organs, achieve better surgical conditions, and greatly improve the treatment ability of various accidental injuries. Among them, injuries such as car accidents are expected to increase the survival rate by 90%, especially in the field of organ transplantation. Obtain a wider range of applications.



Human hibernation is currently only used in medical institutions to treat various critically ill patients. However, damage-free hibernation to slow down metabolism and extend life may be a new hope for space travel. Researchers at the Massachusetts Central Hospital in the United States claimed in the March 2008 issue of "Anesthesiology" that they used a rotten egg-scented hydrogen sulfide gas that could interrupt the metabolism of mice. After a few minutes of dormancy, the mice showed no symptoms when they woke up. any side effects.

The human body has a complete body temperature regulation mechanism that produces strong stress to low temperatures. Therefore, to achieve hibernation, it must be achieved with the help of external equipment based on more in-depth biomedical research and experiments. Moreover, the dormant state only slows down or reduces the body's metabolism. The operation of the body's cells, tissues and organs still requires a large amount of energy to be maintained. Long periods of dormancy can lead to atrophy of the body's muscles and many internal organs and other adverse phenomena. Taking these factors together, the current hibernation technology is not mature enough, and interstellar travel relying on human body cryogenic hibernation can only be considered a science fiction.

But this does not affect people's enthusiasm for cryogenic hibernation. I believe that with the continuous development of cryogenic biomedical technology, human body cryogenic hibernation will become a reality, and travel in the universe will become a reality from science fiction.
