A 4D HyperEarth: 1000x More Space for Real Estate

[QUOTE="Hornbein, post: 6887621, member: 489043"] I'm thinking like this. Let's say our 4D airplane with the same mass as a 3D one has a hundred times as much surface area. That means it has about fifty times as much drag. Fortunately the area of its lifting surfaces also increases a hundred times, so it would have one hundred times as much lift. That seems like enough lift to take off at quite a low speed. Now there is a big advantage that the 4D Earth has only about 1/10,000 the circumference of 3D Earth. So even if your airplane can fly at a maximum of one knot, you are ahead of the game. Akebono can fly to LAX in half an hour. [/QUOTE]
