Gunshot Victims To Be Part of "Suspended Animation" Trials 357
New submitter Budgreen writes: "Knife-wound or gunshot victims will be cooled down and placed in suspended animation later this month. The technique involves replacing all of a patient's blood with a cold saline solution, which rapidly cools the body and stops almost all cellular activity. 'If a patient comes to us two hours after dying you can't bring them back to life. But if they're dying and you suspend them, you have a chance to bring them back after their structural problems have been fixed,' says surgeon Peter Rheeat from the University of Arizona in Tucson, who helped develop the technique. 10 gunshot and stabbing victims will take part in the trials."

This sounds more like science fiction than anything else to me. But if it works and the technique becomes viable to handle patient with heavy injurie - and assuming the patients can be kept suspended for long periods of time without creating further damages, I wonder if the technique could be adapted for space travel. It would solve a lot of problems related to long-duration interplanetary travel.
The idea is not new. I just wonder if this could be the first step in this direction.

It is very unlikely that we will ever be able to use this technology for deep space travel. First, the distance that grate that you need thousands of years to get there. Therefore, the suspended animation must last that long without chemical decay of cellular structure. Second, all the technology in the ship must last that long. We have no technology which is usable without maintenance for that long. Therefore, self-repair ability for everything including the ship itself must be part of the mission. This looks very much, like the man who wanted to travel around the world in a straight line from Peter Bichsel. Third, all that requires energy, which has to be brought with you.
In the end it will also not matter, because when these people reach the distant location, there will be no compatible civilization on earth left. If any at all. 10000 years ago we were sitting in caves. Reading books from medieval time in their original writing is almost impossible to most people today and that is only 500-1000 years. There is no point in deep space travel as long as we are not able to go faster than light or at least close to light speed.
