Brief exposure to vacuum
Claim in the list: A person does not explode in vacuum and can survive about 1–2 minutes (unconsciousness occurs after roughly 10 seconds due to lack of oxygen).
Verification: The “does not explode” part is correct. NASA explains that skin and the circulatory system limit swelling, while unconsciousness follows rapid depletion of oxygen available to the brain; in a historical accidental decompression incident, a person remained conscious for about 14 seconds. “One to two minutes” is not a guaranteed safe survival time: outcomes depend on conditions, and vacuum rapidly becomes fatal. It is also important not to hold one’s breath during sudden decompression, which can injure the lungs.
Conclusion: The body does not explode, and unconsciousness may occur in roughly 10–15 seconds; the stated 1–2 minutes should not be treated as a reliable survival time or safe interval.
