The Cosmos - Vicino Prossimo, Fallar Prime, & Die - Baulopolis & Baulis Prime - B.C. & Alberta
In the real world there’s only one universe that we know of, although our understanding of it has greatly expanded since the discovery of other galaxies a hundred years ago. In The Pulse I imagine that just as we eventually found other galaxies, so we’ll eventually find other universes, even clusters of universes. This is, of course, an enormous assumption. This is, after all, a sci-fi novel.
In the novel there are 13 universes — see the two maps below. Most of the universes are grouped into clusters or belts, all within the greater gravitational pull of the Purple Pulse and the Black Pulse universes.
The Purple Pulse = powerful universe controlled by the Vicinese
Vicino Prossimo = main planet of the Vicinese Union of the Purple Pulse
Vicino Concordia = capital city
The Black Pulse = powerful universe controlled by the Fallarians
Fallar Prime = main planet of the Fallarian Dominion of the Black Pulse
Fallar Discordia = capital city
The Purple Pulse and The Black Pulse universes are the most ancient universes and are the furthest apart. They’re also by far the largest universes — each containing about 8 trillion galaxies. As such, they determine the largest cosmic binary revolution, indicated above by the largest of the broken lines. The Purple and Black Pulse universes aren’t rotating around the universes at the centre of this diagram; instead, they’re being held in a mutual binary revolution. Nevertheless, the gravity of the Middle, Nord and Sood belts helps to keep the two Pulses in mutual revolution.
The Milky Way is part of the Violet Hoop Universe, which is part of The Great Triangle, along with The Green Buzz and The Orange Hoop universes. The Great Triangle is held in a larger mutual rotation with the Grey Phantom universes to its right — The Crimson Stalk, Ataari Lok, and The Copper Tarn.
The distances between universe clusters are extreme. For instance, The Yellow Sky universe is thousands of times further from The Black Pulse than it is from The Frozen Skiff. The distances involved are literally and metaphorically astronomical. While we presently understand our known universe to be about 28.5 gigaparsecs wide (93 billion light-years), in the novel our universe (The Violet Hoop) is 85 gigaparsecs wide (277 billion light-years). (A parsec equals about 3.26 light-years; a light-year equals about 9.46 trillion kilometres).
The Great Triangle is so large that instead of using gigaparsecs (billions of parsecs) it would make more sense to use ‘exaparsecs’ (quintillions of parsecs). Similarly, the distance between the Purple Pulse and the Black Pulse would require the use of ‘yottaparsecs’ (septillions of parsecs). One yottaparsec would equal 10^24 parsecs, that is, 10 to the power of 24 parsecs, or 1,000,000,000,000,000,000,000,000 parsecs, or 3,260,000,000,000,000,000,000,000 light-years. Exaparsecs and yottaparsecs aren’t used in astronomy because there’s nothing that large in the known universe.
