What would happen on the space station in a total vacuum? [/quote] Actually the Mythbusters had a fair bit of trouble re-creating that... They had to first cause a bit of structural damage to the tanker car to get it to fail and implode when they pulled a vacuum on it. [youtube]https://www.youtube.com/watch?v=kM-k1zofs58[/youtube] Furthermore, the pressure vessels of ISS are not tanker cars, they are designed to withstand the pressure difference. [/quote] I work with industrial vacuum dehydrators. I once hooked up to a 550 gallon solid steel tank filled with oil. I forgot to open the vent on the top of the tank before I established a deep vacuum (27 torr). I walked away for a few minutes. When I returned the tank was crushed. Vacuum is a very powerful force. [/quote] Incorrect. Vacuum is not a force. Ambient air pressure can exert a force. ISS is also pressurized from the inside, the vacuum outside exerts no force. ISS is engineered to withstand those forces on its internal pressure vessel. A generic steel tank is not necessarily designed to withstand that. What I said stands. [quote:Idiot] I don't believe that our atmosphere can exist in the vacuum of outer space. [/quote] Doesn't matter what you believe. You're wrong. Your beliefs are irrelevant.
