Boil, Burn or Explode? How You Die in Space
C’mon, admit it. You’ve wondered. You’ve mused. You’ve pondered. At some point in your life — probably after watching a science-fiction movie — you’ve found yourself asking that all-important question: What happens if you find yourself in space without a spacesuit?
I found myself asking the same question the other night after watching Marvel Studios’ Guardians of the Galaxy (best movie ever). I won’t issue any spoilers that intimate how this question comes up. It just does, OK? In its wake, my friends and I were left running through the various scenarios for what would kill you if you were unprotected in space.
Being the only astrophysicist in the group meant everyone expected me to know the answer. While I could have worked up a healthy dose of Male Answer Syndrome, I had to admit that while I knew you wouldn’t explode, I wasn’t sure about the timescales determining which of the other space dangers would get you first. So that’s why I offer this Smithsonian video.
