    But they don’t really need to be that strong unless there’s expected impact.

    Like lighthouses are circular to be strong because they need to take the ocean pounding.

    Rectangles are nice because you can subdivide them into smaller rectangles and doing construction with a bunch of right angles lets you use lots of modular pieces (picture yourself at Lowes in the building materials section: everything’s a rectangle).

      The larger the dome the exponential the forces become. A thousand foot dome has 2 billion pounds of force acting on it. We don’t have materials to handle those kinds of forces.
