Seriously thick!
I was watching "The Naked Time", one of the earliest episodes of the Original Star Trek series. Scotty has to cut through a bulk head to open a door to engineering. When he pulls the part out, the bulk head is 1/4" thick.
Wow, for a space craft, that is pretty darn thick. To hold in pressure versus vacuum, you only need about the same thickness as a soda can. So maybe it is more structural, or to hold up against weapon fire, etc. Also, I'm SURE metal alloys (or what ever) will be much stronger than what were using today, for the same volume.

I was watching Amok Time a few days ago. So funny when Spock goes into heat.
You must have enjoyed watching Scotty pass on the secret of transparent Aluminum to the polymer magnate in ST IV. "Hello computer"

For something built in space and meant to stay in space as a battleship strength is probably more important than light weight.

It is interesting. There is more iron in the Asteroid Psyche than we are presently mining per year, by a factor of almost 10 Million. Star Ships will not be built in Earth orbit. They will be built in the Asteroid belt.

And IIRC the LEM had a wall thickness comparable to 2 or 3 layers of aluminum foil. Of course there were many structural members as well.

Just this Saturday morning there was this science program on TV which featured a product which could be used on a future USS Enterprise, they were calling it "metal foam".

I never mentioned weight, I said thickness.

The doors in Star Wars are even thicker. Remember the Lightsaber burning through? That was armor however.

Syntactic foam! I once dispersed salt into a certain polymer and then let it cure, soak the polymer in water dissolving the salt producing a very very light weight polymer foam with out the use of a blowing agent. Had great properties such as tensile and elongation. Never did much more with it. I guess one could do the same with molten metal.

We snapped Harrison Ford's leg with a door on the Millenium Falcon in the last movie.

You also mentioned the strength (against a vacuum), strength to volume, resistance to weapon fire, thickness related to a soda can, and thickness of 1/4" which are weight related thickness comparatives as you specified no change in material (aluminum like a soda can?).
I read what you wrote and addressed everything in it. A simple thank you would suffice.

I always though a deep spacecraft should have dual hulls.
But they are proposing an inflatable spacecraft so what do I know. Also... isn't it odd star track was supposed to be about a peaceful scientific exploration... and yet they festooned the ship with weapons. ![]()

What if you were to hit a bug at warp speed? Could lose a lot of spaceships that way.

And they won't be built for peaceful space exploration.

I have been watching all the original episodes of Star Trek on Amazon. They have the remastered version on Amazon. It is in HD now so it is real easy to see the seam on Spock's ears. It is funny how low budget the props were. And it was done so long ago. There are no flat screen gizmos. Kirk gets updates on a piece of paper. In the Pilot episode before Kirk when Capt. The episode where Pike is captured they show the orders come out like a FAX. ![]() The original communicators were HUGE. Bigger than a iPhone 7 plus, and the gold lid opened up and had the transistors in view. Since Transistors were high tech back then that was something to show. The communicators were reduced in size a few episodes later. Yea, I am a geek.
