isn't that true with a cylinder? The whole cylinder spins at a certain rate to produce earth-like gravity. The people who walk towards the inside of the cylinder are turning slower aren't they?

It's like the marching bands in the Rose Parade in Pasadena California when they make that first turn to the right. The band members on the outside are almost running and the ones inside only have to take a few steps, yes?

Unless they enter an atmosphere, they should be built to minimize weight per unit of volume - - which would imply a sphere. But, humans are used to rooms shaped as rectangular prisms, so that would be OK. Heck, a step pyramid would be OK. But, given the risk of decompression, I would definitely make them them modular.

Slowly putting together a "replacement" forum at http://writerswriting.proboards.com.

It's still under construction, but come take a look.

I meant walking toward the hole in the donut, toward the center of the cylinder.

A spaceship can be any shape in space, including rectangular. Big, real, interstellar ships will be built in space. Why fight the gravity well when you don't have to do so. If you have to worry about space dust and the like, shape is not the answer. You must have a shield, of a deflector field, something already in the works.

A large, rotating donut is probably the best shape for centrifugal gravity, and has been used in a multitude of SF stories.

Actually, if your spaceship can fly close to the speed of light, you might want it to be shaped more like an aircraft, because at those speeds space would behave more like a gas than a vacuum.

But at lower speeds, the only manned spacecraft I can think of that was designed solely for flight in space was the Apollo Lunar Module, and you can see how aerodynamic that was!
