The pressure differential for a sub at Titanic depth is almost 6,000psi, for a spacecraft in a vacuum it's 14.7psi. It's a very different problem.

The pressure differential for a sub at Titanic depth is almost 6,000psi, for a spacecraft in a vacuum it's 14.7psi. It's a very different problem.
- euroderf 3y agoBut then again, don't most materials work better in compression than in tension ?
- samwillis 3y agoTo some extent but the stark difference in pressures makes it inherently a different problem. It's actually easer to build a balloon than a compressible can. 0.5mm hole in a space craft is a slow leek you can fill with epoxy (it's happened). The same in a sub at the depth of the Titanic, there is no fix and it's not a 0.5mm hole, it's an implosion.
