An at-present
science-fiction idea where a
person or other
creature is placed into a
coffin-like
pod where they are kept alive in an unconscious state. The most important thing you have to know about a hibernation chamber is that it allows the
user to stay alive for
eons of
time. In other words,
suspend mode for
humans.
This is perfect for space travel because even if you can only travel at relatively slow speeds, given enough time, you would be able to reach any point in space.
Science-fiction writers currently have varying ideas about hibernation chambers. Some feel that the person is in a dream state, having dreams for all those years of travel. Others feel that people are completely frozen for those years, without thoughts or dreams.
Lister was placed in a hibernation chamber in the Red Dwarf series although it was called 'stasis'. Maybe these things are called stasis chambers as well. Sylvester Stallone was placed in a hibernation chamber in the movie Demolition Man also starring Wesley Snipes.
