And thier cool space craft was made of aluminum walls not very thick? But to create a close to perfect vacuum on earth they need 5 foot thick concrete walls?
First of all, a vacuum chamber does not require 5 foot thick concrete walls. Second of all when a space ship is in outer space the air inside of the ship is trying to expand out. There is very little pushing against the outside of the ship in the vacuum of space.
What does a space suit look like without the exterior cloth layer? Like
No proof it's a vacuum. The atmosphere would get sucked away. The radiation does in fact require according to the Russians, like 3 meters of lead or 6 meters of water. Also, rockets couldn't work in space because their is no atmosphere to push off of.

Radiation from what?

If you make an explosion in a vacuum it pushes in every direction. If you let a small stream of gas out in a vacuum it will expand and push the thing that let the stream out. Hell in space it is theoretically possible to make a giant "sunlight parachute" to propel an object using the energy from light.
The "vacuum of space" would suck it away The interstellar radiation NASA says is up there and the Van Allen radiation belts Those are theories, rocket engines "push" off of matter so it could take off of a large asteroid or moon, but there would be no continuous push.
