Q&A If this earth were cube shaped would it be possible during Magellanic era using a float ship to figure out that the earth is cube shaped?

While the other posts did already explain the issues with the cube-formed Earth, I just want to give a feeling of the dimensions we are speaking of. Imagine that the centre of the cube's faces are...

  • While the other posts did already explain the issues with the cube-formed Earth, I just want to give a feeling of the dimensions we are speaking of.
  • Imagine that the centre of the cube's faces are at Earth's radius, about 6300 kilometres above the cube's centre (that is, the cube is sized so that actual Earth would be the inner sphere). Then the corners of the cube would be about 4600 kilometres high “mountains”. And even the cube's edges would be about 2900 kilometres high. For comparison, the space shuttle orbits Earth at merely 300 kilometres. In other words, on this cube-Earth you could hike right into space.
  • Indeed, such a cube planet, if it could exist, would likely have six independent habitats, one on each face of the cube, and it would be impossible to go from one of them to the other with equipment from Magellan's era. Basically, you'd need a space suit just to walk there.
