Almost nothing on Earth is perfectly parallel. Let's explore why with a few thought experiments. Two people start on Earth's equator, facing the North pole. They are separated by 90 degrees of longitude - perhaps one person is in a boat on the Atlantic, the other on the Pacific. Since North is exactly perpendicular to each person, their lines of sight are ...

Lots of Curves Rather than assuming your parallel universe cannot have parallel lines, I'm going to assume it's in this universe, but parallel lines are a major cultural taboo and people go to great lengths to avoid them. (so physics works) Architecture would likely use curves to avoid parallel lines. Skyscrapers could be built as cones or domes, and if ...

The stated dimensions (1024 cubic kilometers) is a cube about 10 km on a side. Sophisticated technology wouldn't be necessary, they could walk the sides of the "planet". (To be clear with the nomenclature, nothing with a longest-axis of 17 km is a "planet", it's just a large asteroid. The threshold for "planet" according to the IAU is a 2000 km diameter.) ...

I don't think its possible to have a cubic planet with an atmosphere as gravity would crush the edges, form a molten surface and become round again. You also run into huge issues with water, some sides being cast in a permanent shadow and air flow due to the cubic mountain ridges. But from a technology stand point, it should be pretty easy using the same ...

Yes, Absolutely! Not only can you do such a thing, but in fact boatloads of alternate metric theories of gravity have been proposed both before and after Einstein came out with GR. For instance, the first metric theory of gravity was actually due to NordstrÃ¶m in 1913. Let's go over what exactly the equations governing GR look like, and then we can dig into a ...

Aristoteles proved the earth was round several millenia ago, by looking at the shadow the earth casts on the moon during lunar eclipses. If your planet has a similar moon to earth, then you can determine the shape. Considering the earth is spinning, each lunar eclipse would five you a little more info, until you had the right idea eventually.

Something similar to the "polar projections" of spheroid planets like Earth would probably work well. Your planet has a natural and rather extreme barrier at the equator, so separating the map into 2 "polar" maps, which are separated by this equatorial barrier, just makes practical sense. You could even look at the history of the planet, ...

a 90 degree cliff that you can then vector around is a pretty big one, i like the idea of a waterfall that "falls down" on 4 of those faces continually, but think of what rolling a ball "down" each of the 3 faces of a corner would look like. an Engineered cube of planatoid size would basically just have 8x three faced peaks around a core. you can take this ...

There's a chance that our own Universe doesn't accept parallel lines Lastest astronomical findings may point to the fact that our Universe is not flat, but actually curved on itself, and is a matter of heated debate. On a small, human scale, it means nothing, but in the big scheme of things it changes the development and eventually death of the Universe (a "...
