    Amazing...

    I'm more concerned about the psychological effects of hybernation on humans. It'll be shocking to wake up far away from your "time".

    This is one of those things that has been around forever, but never accomplished. We have to reach absolute zero to do this, and many believe that at absolute zero all matter becomes energy, so it'd be pretty hard to unfreeze the person.

    "The 'hibernation on demand' technique, which has been pioneered in mice, also raises the prospect of putting astronauts to sleep for long voyages in space"

    This reminds of a Twilight Zone were they sent an astronaut into space and made the astronaut hibernate. They sent the guy to space in 1940 were he hibernated for 40 years while robots on his ship did research. He was in love with some girl and didn't want to be young when he gets back so that the two can be together. So he spent 40 years in isolation so that he would age and be able to see his girl again, and when he get's back the most ironic thing happens. The girl instead had been in hibernation for the 40 years and was young while the guy was old. Very Sad! Then, even more ironic is that the ten years after this guy had been sent into space they sent another astronaut that used advanced technology to do the research that this guy spent 40 years doing in a few months. It was a brilliant episode that I think is worth sharing.

    Why do we have to reach absolute zero for human hibernation? Isn't it enough just to have the body's metabolism slow down and not completely in standstill. Hmmm...I don't think even insects who undergo periods where they are completely frozen totally stop all processes of their body.
    But if what you are saying is true, I guess I wont be able to see a person undergo hibernation in my lifetime cuz isn't absolute zero suppose to be unattainable. Ahhhh, now I'm depressed.

    so you think it will never be accomplished? Why?

    sTumped did not say they thought it would never happen. They said it would never happen in their lifetime, citing the impossibility of reaching absolute zero.

    we don't have to reach absolute zero to accomplish hybernation. absolute zero simply means there is no decay whatsoever because there is absolutely no movement of molecules. we've come very close to reaching this temp already, though. but its possible (and more practical) not to put the person at absolute zero for hybernation, especially since they won't be in that state for too long (relatively).

    So even in 40 years, it will not become a reality?

    I didn't say that. For one thing, as Roy Lennigan points out we don't have to go to absolute zero, which would make it impossible. Indeed, we won't have to go anywhere near absolute zero.
    Maybe in twenty years. Maybe in one hundred and twenty. Maybe, one thousand and twenty. Maybe never. I don't know. Indeed, I find the concept only marginally more interesting than European embroidery in the Thirteenth Century.

    Mhmmm, so if the problem isn't the temperature, then what is it? Is it that we can't get to such a low temperature fast enough?

    I have a quet.
    I think the scientists of nowadays already understand how our brains work, and how the chemicals interact that play significant roles in our brains, right? Then why it is impossible to hibernate human into sleeping mode until very fiture?

    Nima,
    water expands when it freezes. This ruptures the walls of cells. That is the major problem.
    Then there is the difficulty of reviving the all (at least most) of the cells to a functioning status more or less at the same time.
    Then there is the issue, that even at low temperatures, some biochemical activity is occuring. In a body that is shut down this activity is not going to be good - decomposition would be as good a term as any.
    And if you happen to believe that the mind is in any way separate from the body, then you have a whole other problem.

    ps2,
    Wrong. Scientists understand a lot about how our brains functions, but there is no comprehensive, well integrated theory that explains it all.

    Even if there were: I know how stars work, in great detail and great accuract, but I can't shut one down for a thousand years then restart it. Brains are much more complex than stars.

    Brain is as complex as many telephone wires connected in NY. But there is always a key that factors how brain being living or unliving. If they know how to stop metabolism of brain and body without--like you say--rupturing cell membrane, it is likely to revie a sleeping person.

    Right Ophiolite, but if the body temperature gets close to absolute zero fast enough, there won't be time to kill the person.

    some biochemical activity is occuring. In a body that is shut down this activity is not going to be good - decomposition would be as good a term as any.
    vacuum maybe?

    Before reaching absolute zero, you will reach 0º C and water will freeze, then cells will explode. And anyway, absolute zero will kill the person. Think about it: getting close to 0º K means to drain energy form the body, until all molleculles come to a stop. this is a one-way road, as once the mollrcullrs start getting more energy, they won't get it in the righ tim and the right dose. There is no way to restore the dynamic balance on which life is based. A living bieng is a delciate balance where a trilion things are going to hell and another trillion thigns are struggling against destruction, simultaneously. Putting it to a stop through absolute zero, or close to absolute zero, will just destroy the "moving" system, and no force in the universe will restore it back to its original balance.

    As for hybernation, my personal guess is that there is a bigger chance that other sciences will render hybernation useless or needless before practical hybernation happens. Maybe we can find a way to slow down life over long periods of time, but a complete stop-and-restart will never be possible.

    They must have installed an awful lot of telphones since I last checked. You are out by several orders of magnitude. So many, in fact, it makes your comparison meaningless.

    Nima, it doesn't matter how fast you freeze the cells, the water still expands, and the cell wall is potentially ruptured. There do seem to be some methods (the details of which I am very hazy on) that might get around this problem, but at present it is a major, major stumbling block.

    Placing the body in a vacuum will do no good, since the cell constituents are not in a vacuum. Biochemicals are unstable. It is only through the continual input and expenditure of energy that we maintain our integrity. With that system shut down slow, but progressive degradation of the body is likely to occur.

    More long term pessimism has been generated by individuals and groups confusing optimism with realism.

    Optimism has to be based on a solid foundation. I am not saying these things are not possible. I am saying they are not possible now, and I am identifying some of the issues that must be dealt with for success to be achieved.

    A blind optimism that believes we shall achieve our goals with little or no effort or ingenuity is doomed to failure. I am opposed to failure: I am opposed to blind optimism.

    I believe this a complete possibility in the very near future.
    Just take a look back 20 years ago at science then compared to science now.
    The ability to take a person with serious illness and slow the cell rate down would provide for a multitude of medical possibilities. I think that the only thing standing in the way of ideas and theories in general is the fear of what they are capable of... I know that sounds stupid but the rate that technology is advancing is ridiculous it wasn't all that long ago that we used horses as a major form of transportation... (which might be a good idea to go back to considering gas prices) lol....

    Looking back. Trying to spot a huge difference. No. Can't quite see one.
    Yes, we have defined the human genome. We were only planning that twenty years ago.
    String theory. Damn. That still hasn't died off!
    I could go on. I shan't. What do you think is so dramatically differnt today from 1986?

    Unless we figure out how to freeze time within a small enclosure, long-term hibernation probably isn't very likely to happen anytime soon. The short-term hibernation induced in the mice, however, shouldn't be too difficult to induce in humans, so brief periods of dramatically lowered metabolism to assist surgery may be feasible in only ten or twenty years.

    Your are right those theroies have been around for a while. But technology hadn't caught up to those theories. But now tech is moving at such an amazing rate that some of those theories might actually get that technology that it so desperatly needed in 1986. How man other theories and ideas have been put on paper but did not have the tech to support it yet. And if you cannot look back and notice a dramatic increase in technology I would have to ask if you are able to see. What was a computer in 1950 compared to the capabilites of PCs today...? Advances in flight from the times of the Wright brothers... The development of GPS and it's uses... These were all probably ideas on paper at some point that people like us debated if they could exist or not.. But guess what here they are right in your face... And do you not thinl that moving from an Equine as a mojor source of transportaion to being able to circle around the earth in 90 mins (space shuttle in orbit).... Overall I think that if you look a little harder you might see that there have been a rather significant change.....

    I think this is very difficult. Making human being hibernate for short time is more practical, for examples, lasting one or two hours. Maybe, in the future, hibernating for two hours is very normal.
    The metabolism is one of characters of life. When the metabolism of cells is ceased for a long time, we can think these cells died, can't we? So that's the reason I think this is very difficult.
