All these arguments sound persuasive at first, until you think them through. The people who promote this stuff do it mostly in bad faith to sucker people with moderate-to-low intelligence. The lure of "hidden knowledge" is the same thing many religions and cults sucker people with. Don't fall for this crap.
A vacuum chamber is designed to keep all pressure out while a space suit/capsule/habitat is designed to keep pressure in. Creating strong vacuum is a fundamentally different task from maintaining 1 atmosphere of pressure. You essentially have to evacuate all the molecules bouncing around in the chamber, which gets exponentially harder to do the fewer of them left.
To equate the two like you do in this disinfographic is just dumb.
You're not addressing the main point. Which is that NASA supposedly sent MANNED vehicles into an environment without testing them first for the ability to handle that environment. This is UNHEARD OF in industry and engineering.
If it's so easy to build craft that handle 10^-12 torr vacuum, why not prove it in a vaccum chamber on earth?
What side is vacuum only matters structurally. The seals on hatches, space gloves, windows, any joint between materials, they all need to handle 10^-12 torr vacuum. That's hard because traditional seals like o-rings outgas at that pressure. You need metal on metal, single time use, seals. Without those, your precious 1 atm is leaking out into space FAST.

I disagree. The reason the seals matter in a vacuum chamber is because you have to create the vacuum, which is very hard to do. If the vacuum already exists (in some area of space) all you have to do is seal against 1 atm of pressure escaping. You seem to be under the impression that high vacuum is somehow the inverse of high pressure. It's not. It's just absence of pressure, so you only need to seal against the amount of pressure your vessel needs to hold.
It should be obvious that a suit or craft that can maintain 1 atm pressure in a 10^-6 Torr vacuum can also maintain 1 atm pressure in 10^-12 Torr vacuum. There is no practical difference at that level when your goal is to maintain pressure.
I would say I have a basic understanding of outgassing, but that would be more of a problem if your concern is trying to create or maintain a high vacuum. It's not a problem if you just need to maintain pressure. Pressure and vacuum are not the inverse of each other. Vacuum is merely the absence of pressure.

You don't understand the concept of out gassing.
