| After much debate on Twitter, I understand this better now. https://twitter.com/lproven/status/1564613978155802631 For a post that claims to be explaining something, I have to say, I think it's really quite stunningly poor at explaining itself. This is not about living on a torus. As others have said, a torus is a perfectly possible 3D object in our universe, and SF has many toroidal habitats, including the original Larry Niven Ringworld and Iain M Banks' "Orbitals" as used in several Culture novels, and as also used in the videogame Halo (I believe -- not played it; not a gamer). Since the article is called: > Living on a Torus Note: on And begins: > life in a three-dimensional torus that measured only several metres in each dimension That to me implies inside an object. A toroidal habitat is an absolutely standard part of SF and has been since before 2001: A Space Odyssey in 1969. The article is in fact about living inside a spacetime continuum, a universe, which is toroidally shaped, and strangely small. (What you are on is unspecified.) It doesn't say so but it seems to be. Since I have never really wondered about the shape of spacetime, I could not even begin to parse the essay. |
