	In Response To: Alien Resurrection (MrHen) : I would suggest not repeating any of the science in that movie without : looking it up first. More than likely the hybrid would have just pulled : away from the wall and continued with a rather noticeable hickey. It has : been a while since I have seen that movie, but I vaguely remember the : entire creature being squeezed through a hole less than the size of a : quarter. Implausible is the nicest way of putting it. : Based off of the little information I have gathered, you would probably be : able to place your hand over a hole that breaches into hard vacuum without : much problem. It would eventually get rather cold, but your hand would : remain intact with no serious injuries. Yup; skin is incredibly tough stuff. : A leaking space suit would cause more problems due to lack of oxygen than : problems of pressure. If there was an open wound, I would expect a : globular blood flow to start squirting out of the victim and the oxygen : leak to begin causing problems. I would not expect any problems involving : organs or muscle mass to start pushing their way through the skin nor : would I expect a huge increase in blood loss. Rather depends on the type of space suit. I can elaborate if you'd like... : Of course, this is all very "boring" if you are just looking for a : cool way to describe someone dying. I find scientific ignorance to be : really annoying, but if it is something you are willing to endure, than so : be it. Plot trumps science in entertainment. Just look at the ending of Total Recall... : If one did happen to get themselves shot in a space suit while meandering : around in hard vacuum, I would guess the best thing to do is to slap some : duct tape over the hole. If the wound is too serious to ignore, than the : poor bloke would probably want to contain the oxygen loss and then attend : to the wound. If the oxygen is not a concern, cutting a hole in the suit : to patch up the wound should be okay. Reasonable, in a current space suit. It's been conjectured that the main use of bullet-resistant vests in saving lives has nothing to do with stopping bullets - it's that they keep the innards in roughly the right place until the surgeons go in and fix things... : All opinion, obviously, since I really do not know too much about pressure : systems. Pretty accurate, though. More on combat in space at a personal level here: http://www.projectrho.com/rocket/rocket3l.html and also on space suits and their protective value: http://www.projectrho.com/rocket/rocket3m.html (you'll need to extrapolate a bit...) As an aside, I always reckoned the Marine's spiked knuckles were a good idea. Makes it very easy to smash a faceplate, which neutralises anyone suited rapidly.
