AI Thread Summary

This information supports the realism of interstellar travel in science fiction narratives, allowing for plausible changes in starship destinations.

Thread 'Map of a 4D planet'

A map of a four-dimensional planet is three dimensional, so such can exist in our Universe. I made one and posted a video to the Internet. This is all based on William Kingdon Clifford's math from the 19th century. It works like this. A 4D planet has two perpendicular planes of rotation. The intersection of such a plane with the surface of the planet is a great circle. We can define latitude as the arctan( distance from one plane/distance from the other plane). The set of all points...
