Then there is still hope, some form of liquid must exist that could be contained to do some serious long term liquid cooling with a properly isulated Enclosure/Pipeline that can handle this sort of severe torture.
if this liquid and Enclosure doesnt Exist, whos to say we cant make one?
I would wager nothing is impossible, but why use a liquid? Liquids are costly and the manner in which containing and getting them into space is not cheap. I would image something more stable, perhaps a metal that can get rid of the heat much like a heatsink? Since the background temperature of space is near absolute zero, and considering the second law of thermodynamics (http://en.wikipedia.org/wiki/Entropy
). I think with any space application it should be a matter of obtaining the most effecient materials and processes. However not to stifle innovation, what liquid and what kind of system would you propose for cooling?

As I said in the first few posts, the temperature that you would feel is -260, but space on it's own has no temperature. The reason we are warm on earth is because the sun heats up the air, the air retains the heat and we stay warm.
That in addition to the ozone etc etc.
Not to call you out, and since you are apparently an astrophysicist (seriously, and not to be mean, but this was a large part of my life for some time), here is more information stating that what you believe is simply wrong. Not to be rude, but now you are sincerely asking for this:
(Also here is another one that is a bit easier to read)
Also, if there is no temperature in the vaccum of space that would mean space would exist at absolute zero, this is the point where all atomic and quantum movement stops. period. If space had no temperature, then the universe as we know it would not work the way it does, (i.e Photons would stop in thier tracks beofre leaving the mass of thier star.) This can be debated of course (though I dont think you will make much headway), however you simply believing that you need 'atoms and molecules' to retain temperature is wrong beacause you forget about the huge swath of subatomic particles that can populate any point in space at any time. Cosmic background raditation is a large part of that temperature that exists in space. The comment of yours that i have bolded
proves the point I am making. If the sun heats up the air on the planet (which I would believe no reasonable person would disagree with) then how does that heat get to the planet? There is obviously a transition period of where the particles traverse space in between the sun and the planet, hence the heating of the planet. I don't believe any sane person would argue that photons quantum tunnel to the planet and forget about any kind of motion laws that describe our universe.
I challenge you to prove me otherwise.Edited by Weasel555 - 11/30/11 at 6:06am
