Cryonics, also known as cryogenic freezing, is a technique that involves keeping human remains at very low temperatures with the hope of bringing them back to life and health in the future. This bold claim is based on the assumption that future medical and technical advancements, especially in nanotechnology, will be successful.
Many people use the term “information-theoretic death” to describe the basic idea underlying human freezing. The concept posits that irretrievably damaged brain functions and information, beyond the reach of future technology, mark the end of life. Cryogenic preservation is the only hope for continued life for many people who are resuscitated if exposed to temperatures of 32°C and below.
However, the cryonics field has huge deficiencies, including ethical problems and possible scientific difficulties, and the process could be more controversial. Not everyone agrees that cryogenic freezing is a helpful alternative treatment for those who have tried all the medical options before, and others are critics who think issues of science and ethics may arise.
Human freezing is a complex and emotional process. Before cryogenic freezing becomes a viable option, it must first pass several technical and medical hurdles. To treat patients, we need devices that can diagnose their diseases and perform certain treatments. We also need to identify causes of death and develop necessary strategies.
Devitrification occurs when cryogen-frozen bodies are heated, causing cryoprotectants to re-solidify and disperse throughout the body. Once these chemicals reach glass transition temperatures, they become internally toxic. Blood must be replaced before reheating to avoid damage to the cells.
But when you heat water to a crystalline temperature, ice crystals form. To avoid this, you would have to warm up quickly to prevent ice from having a chance to form. We don’t have the technology to cook it accurately right now at that level.
Because organs heat up so quickly, body temperature is also important, adding additional complexity. Regenerative heat has worked for smaller creatures, but it’s not easily executed on a human scale.
There is no guarantee that people will recognize or retain pre-existing memories and information after cryogenic freezing. Since the activities needed to bring body cells, blood vessels, organs, and tissues back to life are more complex, it is hard to believe that the minds and bodies of the resurrected ones will not change at all.
Besides all these mysteries, there are problems about the kind of life they have. They were traveling back in time to a strange place hundreds of years after their departure, where they wouldn’t meet familiar faces because everyone they knew would die.
How would they live in this world? What would they do to stay alive? Bioethicists pose the How would they survive in this world? What would they do to survive? Biologists risk further social exclusion, loneliness, despair, and disease. When people feel lonely, frightened, and isolated, it may not be pointless to live longer.
The impact of human freezing on other individuals and the environment is another concern. With so many people in the world and so few resources, some say that it is selfish to try to extend people’s lives beyond what is acceptable, especially if they have reached a glorious age.
Since death is an inevitable part of life that contributes to population stability, maybe we should just accept it and focus on caring for the living and stop trying to live forever.
Despite many obstacles and criticisms, the hope of conquering death and the desire to understand life’s challenges are driving the cryonics industry to push the boundaries of science. Cryogenic freezing offers an intriguing junction of science, ethics, and the concepts of life and death, while we still don’t know for sure whether it may be a ticket to the future.
As the years go by in this century, more and more people will have strong opinions about cryonics. The next few decades will undoubtedly determine the scientific integrity and societal acceptability of cryonics. Human freezing is still an idle hope, until science can fulfill our desire for eternal life.
For the time being, cryogenic preservation is evidence of human ingenuity, our drive to overcome death, and our unwavering quest for immortality. It offers an intriguing story about humanity’s potential future, but it also begs more questions than it solves. In our quest for immortality, time will tell whether it turns out to be a guiding light of hope or an illusion.
No matter how much we debate the future of possibility, the same question remains: would you want to return even if it were possible? If you cut off all that made your life worth living in the first place, you would find yourself stranded in a strange world.
With this, you can’t possibly lose and still stand to win. In science, we are still making progress by discovering what does not work, regardless of its efficacy. If cryogenic freezing works, we may have stumbled across a temporary solution to death.
