that’s the atmosphere exerting a inward force on a vessel designed to withstand outward force.
In space ( in a space suit ) the situation is reversed, pressure inside suit vs zero pressure outside. As long as the suit is capable of holding in 15psi or so of pressure in what would the problem be?



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.

wrong


Good job! Admitting there's a problem is the first step towards recovery!

Card just can’t un-equate idea of a vacuum cleaner when thinking of a vacuum in space. He also thinks like a sith in absolutes which is why he can’t understand how earths atmosphere gradually gives way to the near vacuum of space. And ofc he certainly can’t understand how it’s earths gravity that keeps our atmosphere around us. And it’s unlikely he understands or accepts F=dP*A as reality or the mechanic behind a ‘vacuum’ that lifts objects weighing tons.


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.

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.

Yup , he has no idea what the difference between gauge and absolute pressure means.

Inward force vs outward force?

Because Earth is the size of a merry-go-round obviously.

Ever negotiated a gradual curve in the road at 110km/hr fine but spilled coffee taking a sharp curve at much lower speed? The next step would be to pick up a book and understand why. GL
