Various animals can lower their metabolism in nature by lowering their body temperature. How possible is it to do this for modern science? Is there cryogenic sleep for space travel?Ĭryogenic sleep can be considered a kind of artificially induced human hibernation. This is a method in which we could put astronauts into an artificial coma, putting them in capsules or chambers where they would remain asleep for decades or even centuries and then wake up until they reached their destination.
In the solar system alone, the planets are so far away that going from one to another would take several years or even decades while going to the closest stars would take centuries or thousands of years.Ī human being cannot carry out such a long journey since we do not live that long, so a possible solution to this problem is cryogenic sleep or induced hibernation. One of the most critical problems for space travel is the enormous distances at which objects are found.
