I finally saw Sunshine. I was expecting a science fiction film with a ridiculous scientific basis for the high concept and Hollywood science everywhere else. What I got was a psychological thriller set in space with an ridiculous scientific basis for the high concept and Hollywood science everywhere else, though not quite as bad as I had thought. Weirdly, of all the things that were wrong, the one that really bothered me was that Harvey froze when exposed to the vacuum of space in seconds, citing the fact that it was -270 degrees Celsius or thereabouts. The problem being that in the Vacuum of space you aren't about to lose very much heat no matter how cold it is. Heat loss or gain as a result of temperature differences occurs via conduction, which will be negligible is space, especially over the period they were exposed. The only heat loss will be by radiation, which is not especially quick.
