I finally got round to watching the first film and was blown away. I did some googling and upon learning about this sci-fi superhero team consisting of a talking raccoon and tree man I was hardly impressed. It won't be pleasant, but it won't be like the movies, either."ĭespite being a huge comic book nerd I was not familiar with the Guardians before the first movie came out. So, there's at least one data point about what it's like to be in a vacuum. He later said that his last conscious memory was of the water on his tongue beginning to boil. Technicians began to repressurize the chamber within 15 seconds and he regained consciousness at around the equivalent of 15,000 feet of altitude. He did not pass out for about 14 seconds, by which time unoxygenated blood had reached his brain. The pressure issue would also make it impossible to hold air in your lungs, so you would pass out within a minute, but likely much sooner: "In 1965, while performing tests at the Johnson Space Center, a subject was accidentally exposed to a near vacuum (less than 1 psi) when his space suit leaked while in a vacuum chamber. Your tongue would be susceptible as well. Correction: The pressure is important: Your eyes, if left open, would basically boil and surface freeze because of lack of pressure on the liquid. In fact, if you were to float in sunlight you'd sooner cook than freeze. This is what makes a vacuum a good insulator. In a vacuum the only way to lose (or gain) body heat is through thermal radiation. People exposed to the vacuum of space do not freeze in a matter of seconds/minutes.
