Is space really cold?

  1. Nov 24, 2013 #1
    If someone stepped out into the vacuum of space, would it really be cold? Wouldn't you need an atmosphere to feel the heat or cold? Say your in intergalactic space. Approximately how fast would it take to freeze to death? I am assuming the only way your body heat could leave would be through black body radiation. Ignoring the fact that you would explode due to lack of pressure...
