There is always conflict between the Science and beliefs. Science never accept the beliefs of people. It always tries to prove that human beliefs are not real.
Today Science has attained and has come long way through many reseraches. Though it tried hard to prove human thoughts wrong, somewhere it too followed for many researches. Today Science has reached such a level that some of its reseraches are beyond human thoughts. One such technology that Science has found out is the ‘Cryonics’.
Cryonics is the low-temperature freezing and storage of human remains, with the speculative hope that resurrection may be possible in the future. Cryonics is regarded with skepticism within the mainstream Scientific community. Cryonics is an effort to save lives by using temperatures so cold that a person beyond help by today’s medicine can be preserved for decades or centuries until a future medical technology can restore that person to full health.
Cryonics sounds like Science fiction, but is based on modern Science. It’s an experiment in the most literal sense of the word.
But the most immediate medical application is in the field of cryonics — freezing organs for transplantation. The first body to be cryogenically preserved for this reason was in 1967, frozen by a former TV repairman with no Scientific or medical background. Since then, the field of cryonics has been viewed as quackery by the mainstream.The Science of cryonics has evolved much in the last half century, and together with visions of nanomedicine, immortality research, mind-uploading, AI discoveries, and other technological advances, cryonics doesn’t seem as implausible as it used to.
Cryonics procedures can begin only after the “patients” are clinically and legally dead.
Cryonics procedures may begin within minutes of death, and use cryoprotectants to try to prevent ice formation during cryopreservation. It is, however, not possible for a corpse to be reanimated after undergoing vitrification, as this causes damage to the brain including its neural circuits
Cryonicists argue that as long as brain structure remains intact, there is no fundamental barrier, given our current understanding of physical law, to recovering its information content. Cryonics controversially states that a human survives even within an inactive brain that has been badly damaged, provided that original encoding of memory and personality can, in theory, be adequately inferred and reconstituted from what structure remains.
Cryopreservation has long been used by medical laboratories to maintain animal cells, human embryos, and even some organised tissues, for periods as long as three decades.
Large vitrified organs tend to develop fractures during cooling, a problem worsened by the large tissue masses and very low temperatures of cryonics. Without cryoprotectants, cell shrinkage and high salt concentrations during freezing usually prevent frozen cells from functioning again after thawing. Ice crystals can also disrupt connections between cells that are necessary for organs to function.
Cryonics is generally regarded as a fringe pseudoscience.The Society for Cryobiology rejected members who practiced Cryonics,and issued a public statement saying that Cryonics is “not Science”, and that it is a “personal choice” how people want to have their dead bodies disposed of.
