2/12    If space is a vacum how is heat dissipated in a spacecraft?
        \_ Space isn't a true/pure vacuum.  Roughly 1 hydrogen atom per
           10 cubic centimeters in deep space.  So they say.  I haven't
           personally measured.
           \_ What's your point?  Are you trying to assert that this
              low density of gas removes significant heat?  Or are you
              just spouting idiotic irrelevancies?
              \_ I think his is just trying to say that space is not a vacuum.
                 \_ Yes.  That's what I was saying.  Unfortunately, some motd
                    posters are too clueless to recognise a simple correction
                    of fact for what it is.  "If space is a vacum[sp] how..."
                    is based n the false premise that space is a vacuum.
                    \_ Perhaps you need help -- look up "sophistry" in the
                       dictionary.  Perhaps "semantic" and "specious" as
                       well.
                        \_ Nice try but the dictionary won't help you.  You
                           were just being stupid and obnoxious.
                           \_ No, actually I'm saying that this fool is
                              puffing himself up with easily acquired
                              information, without actually answering
                              or in any way addressing the question.  Oh, and
                              speaking of the dictionary, you might want to
                              start by looking up "clue" before posting again.
        \_ infrared, low frequency EM
        \_ they use radiators.  Black body radiation isn't as efficient
           at getting rid of heat as conduction is, but when you have no
           atmosphere, it's yer only choice, unless you want to waste a
           lot of mass in evaporating or ablating a cooling  material.
           \_ someone who's not an idiot!
                \_ Yourself?  Don't be a fool, idiot.
        \_ Same way as how heat is dissipated from the Sun.
