>>43331859>1) Make it really long and thin, so that it'll snap under the slightest gravitational stressIt's 'really long and thin' because that's the most efficient design for space. The biggest hurdle with space is keeping your weight down while you try to get shit into orbit, so constructing a spaceship in orbit which is essentially one long corridor is really cost-effective.
Also if you're hitting enough gravity to cause it that much stress, your astrogator did something wrong.
>2) Put all the fuel tanks on the outside where space debris can strike them unimpeded>>43331886>3) GIANT RINGS -- bonus points if connected by skinny-ass pylonsThe GIANT RINGS might have multiple purposes depending on the intention of the designer. Off the top of my head:
>360 degree sensors>maneuvering via gyroscopics>some kind of living space (as noted by another anon)>The external part of an Alcubierre drive, assuming the sci-fi be soft yet it wants to be seen as hard.
