This Video is about how todays scientists freezing humans at low temperature in a liquid nitrogen tank to preserve them for the future because they think the resurrection may be possible in the future. Translation : Aj ki yeh Video Cryonics kay baray main hai kay kesay aj kal kay scientist maray hoye insanoon ko aik liquid nitrogen say bharay tank main rakh kay un kay brain ko zinda rakh rahay hain takay jab future main koi aesi technology banay gi jo maray hoye insanoon ko zinda kr sakay tu inhein bhi zinda kia ja sakay jo kay in tanks main preserve hain. IS IT POSSIBLE TO BRING THE DEAD BACK TO LIFE ? LINK OF VIDEO : https://www.youtube.com/watch?v=yFGjw1FFD9c Cryonics is freezing humans 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. Cryonics procedures can begin only after clinical death, and cryonics "patients" are legally dead. Cryonics procedures may begin within minutes of death, and use cryoprotectants 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 networks. The first corpse to be frozen was that of Dr. James Bedford in 1967. Cryonics uses temperatures below −130 °C, called cryopreservation, in an attempt to preserve enough brain information to permit future revival of the cryopreserved person. Cryopreservation may be accomplished by freezing, freezing with cryoprotectant to reduce ice damage, or by vitrification to avoid ice damage. Even using the best methods, cryopreservation of whole bodies or brains is very damaging and irreversible with current technology. Cryopreservation was applied to human cells beginning in 1954 with frozen sperm, which was thawed and used to inseminate three women. The freezing of humans was first scientifically proposed by Michigan professor Robert Ettinger when he wrote The Prospect of Immortality (1962). In April 1966, the first human body was frozen—though it had been embalmed for two months—by being placed in liquid nitrogen and stored at just above freezing. The middle-aged woman from Los Angeles, whose name is unknown, was soon thawed out and buried by relatives. The first body to be frozen with the hope of future revival was James Bedford's, a few hours after his cancer-caused death in 1967. Bedford's corpse is the only one frozen before 1974 still preserved today. THE CONCEPT OF CRYONICS COMES FROM CRYOGENICS In physics, cryogenics is the production and behavior of materials at very low temperatures. OR The branches of engineering that involve the study of very low temperatures, how to produce them, and how materials behave at those temperatures.
