    I don’t think the skyscraper would be rectangular but likely more circular which would make them extremely strong. Our current technologies could easily build them and with compartments, they would be relatively safe. Building them would be quite difficult.

    A comparable dome on the other hand would be subject to incredible forces if it was to be a single unit but hold that of a skyscraper. A dome of say 1000 foot diameter, would experience some 2 billion pounds of force at sea level atmosphere. It scales up bad and for anything large it is not practical nor do we have the technology or materials. Small domes on the other hand are quite practical and make a great deal of sense and we could build that.

    In reality, a skyscraper would just be a tube with a pressure dome on top.

        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.
