thats wrong, thats the vacuum suddenly and violently expanding outward and as a result it crushes the 1/2 inch steel like wet paper. Its done with huge temperature changes. Imagine that force multiplied by the infinite vacuum of space and compare it to our supposed tiny weak force of gravity, maybe you'll begin to see the issue.
So get a space suit and tell nasa you want to be in that vacuum in Florida for 5 minutes [after it gets down to full vacuum status] but before you do make sure you sign your will ok, you can leave out your space posters - no one wants them anymore.
That’s one the most idiotic things you’ve ever posted. It’s definitely 100% what I said it was. The temperature change is what causes the pressure diferental when say steam condenses to water leaving a partial vacuum. If you could teleport the vessel into space nothing would happen as there’s is no inward force to cause a collapse when the differential pressure is near zero.

Good job! Admitting there's a problem is the first step towards recovery!
And he also doesn't grasp that there's a really short distance that a localized vacuum can lift, and that a vacuum actually operates by the air pressure all around (better say "under" for card) an object pushing the object up, not because it is being sucked up.
Yup , he has no idea what the difference between gauge and absolute pressure means.
