A friend of mine believes that the Earth is flat. I challenged him to prove it by walking off the edge...

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.
Furthermore, the pressure vessels of ISS are not tanker cars, they are designed to withstand the pressure difference.
Quoting: Astroshill 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. 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. I don't believe that our atmosphere can exist in the vacuum of outer space.
Quoting: IdiotDoesn't matter what you believe. You're wrong. Your beliefs are irrelevant. You're right, I should not have used the word force. Is it powerful? What I witness was powerful. Yes, 1 atm pressuring on a non-reinforced steel container around every square inch of its external surface does exert quite a lot of force if there's nothing inside. ISS was not designed with a pressure vessel that is just a regular can of steel. If you've never seen what a spaceship pressure vessel looks like then go take a look at the KSC visitor center on the right side of the Imax theater. They have an unused pressure vessel for Starliner on display.
