Can humans be resurrected in the future? What is the science behind cryonics?
Cryo-technology has always been the frontier of human exploration of the continuation of life. The purpose of this technology is to store human remains through cryogenic freezing, in the hope that future technological developments will allow the resurrection of these deceased people. While this is a fascinating idea in theory, its practice and science remain shrouded in controversy.
Many in the mainstream scientific community are skeptical about this, believing it to be pseudoscience.
Conceptual basis of cryogenic technology
Proponents of cryonics believe that as long as the brain's structure is preserved, it may be possible to recover its information content in the future. At the same time, they argue, memories can still be retained when the brain is at rest and inactive. However, scientists are highly skeptical of this view, believing that we cannot currently guarantee both resurrection and brain integrity.
The cryonics process is performed upon the death of the noble, using antifreeze to prevent ice crystals from forming.
Current status of cryogenic technology
Since the case of the first frozen human, James Bedford, in 1967, about 250 bodies have been cryopreserved in the United States. In 2014, 1,500 people were scheduled to be cryopreserved after death. Despite widespread publicity for the technology, the cost of cryopreservation ranges from $28,000 to $200,000, making it prohibitive for many people.
Maintaining the health of organs during the spray cooling and solidification process is a major challenge with current technology.
Obstacles to Success: Preservation and Recovery
Although cryopreservation technology has been used in the study of biological cells and human embryos, the freezing process of large animals and organs still cannot achieve revival. Ice crystals cause structural damage to cells and tissues, making resuscitation an impossible task.
Many scientists point out that frozen organs are generally not successfully restored to function.
Legal and ethical issues
Laws in many countries treat cryopreserved bodies as if they were deceased, creating legal barriers for those who want to undergo cryopreservation. In some countries, such as France, legal restrictions on cryonics have prevented the development of this technology. Even in the UK innovation case, the courts' support for cryopreservation called for better regulation.
Future Prospects and Challenges
The development of cryogenic technology is part of science and technology's exploration of future possibilities. Although there is currently no scientific evidence or technology to support the argument for resurrection, the scientific community is full of debate and thinking about this technology. Critics argue that this somehow changes perceptions of death, while supporters see potential social benefits.
The discussion on cryonics technology inevitably leads to reflections and moral doubts about the future of mankind.
With the advancement of science and technology, we can't help but think about a question: In the future, will cryonics technology bring about the real possibility of resurrection, or is it just a phantom in a dream?
