I just saw a movie where the main character, a British secret agent, is revived after 30 years on ice. Are scientists actually working on this stuff?
The science behind the idea does exist. It’s called cryogenics — the study of what happens to materials at really low temperatures. Cryonics — the technique used to store human bodies at extremely low temperatures with the hope of one day reviving them — is being performed today, but the technology is still in its infancy. The idea is that, if someone has “died” from a disease that is incurable today, he or she can be “frozen” and then revived in the future when a cure has been discovered. A person preserved this way is said to be in cryonic suspension. To understand the technology behind cryonics, think about the news stories you’ve heard of people who have fallen into an icy lake and have been submerged for up to an hour in the frigid water before being rescued. The ones who survived did so because the icy water put their body into a sort of suspended animation, slowing down their metabolism and brain function to the point where they needed almost no oxygen. Cryonics is a bit diff
