    Nothing is ever 100% safe. Risk assessment is a big part of federal regulations. (See refs at JSTOR and NCBI) One of the key questions is what is the cost/benefit balance for a product. Kitchen knives are hazardous, but it’s very hard to cook without them, so they balance heavier on the benefit side despite the risks. Radithor is all risk and no benefit, so it was an easy decision to ban it.

    The point ContrarianTrail was making is that there is some risk in nearly everything. People have died as a result of garden tools, cars, house pets, shaving, buckets, toothpicks, baseball, etc. Here’s a list. The part he left out is the cost/benefit analysis. I prefer pull cords on my blinds, and I find the new regulations annoying. But I guess some federal agency decided they aren’t so useful that it’s worth the risk to children. And it would be selfish to be all upset about it if it saves some child’s life.

    It’s well established in the Star Wars universe that all you need to create gravity is a floor. Take, for example, any scene from within any of the space ships. Gravity is never a problem.

    Of course, a deep chasm also seems to create gravity, as seen in the first movie when Luke and Leia swing from one ramp to another to escape the stormtroopers chasing them.

    Regardless, it’s easy to see from the blueprints that the layout is stacked like your first image.

    Edit: upon closer examination it turns out it’s both. The plans show three ‘concentric surface decks’ that apparently work like your second image. So I guess the answer is ‘it depends on where you are in the death star’, and, I guess, which way ‘down’ is where you are.
