"Think of it as a ladder. On the bottom rung is all of space. Higher up is Hell and then Snake Way. At the next level are the planets of the four Kais who oversee their parts of the universe. And higher still, above the four Kais and all the rest is the Grand Kai's planet."
The universe (宇宙, uchū) is the totality of existence, including planets, stars, galaxies (銀河, ginga), the contents of intergalactic space, and all matter and energy. There are twelve universes in the Dragon Ball series, and the Seventh Universe is where planet Earth is located.
Contents and structure
In Daizenshuu 4, Daizenshuu 7, Dragon Ball Landmark, and the Dragon Ball: Super Exciting Guides, Akira Toriyama explains that he envisioned the Dragon Ball cosmos as a big ball. This ball is divided up in two halves: the lower half is the realm of the living (or "The Universe") and the upper half is the Other World (or "The Cosmos"), with Hell located between the two halves.
The realm of living is divided into four quadrants based on the cardinal directions, each ruled by a Kai chosen among the Shin-jins from Planet Kaishin. There is one Check-In Station for the four Quadrants of the universe, which allows its inhabitants to go to the Other World. The Kais live in the Other World, on planets positioned at the four cardinal points of the cosmos. There are roads leading to each Kai's planet; notably, North Kai's planet is at the end of a Snake Way which starts from the Check-In Station. The Grand Kai's planet is above Heaven, which is a gigantic planet in the center of the cosmos.
The planet of the Kaioshins, the top-tier deities of the universe who watch over both the Other World and the living world, is located outside of the ball, in the Sacred World of the Kais. The Kaioshins are Gods of Creation who provide the catalyst for life and planets to be born. In order to provide a balance to the constantly increasing number of planets, the Gods of Destruction regularly destroy life and planets. There are twelve Gods of Destruction, one for each universe, and Beerus is the God of Destruction of the Seventh Universe. The Demon Realm, where the Makaioshins (the complete opposite of the Kaioshins) live, is located on the very bottom pin/tip shaped of the universe.
In the computer game Dragon Ball Online and the manga Jaco the Galactic Patrolman, it is revealed that using a Time Machine is ultimately a violation of the laws of the universe. It is explained in Dragon Ball Online that a deity called the Lord of Time watches over the flow of time from the cosmos, and it is mentioned in Jaco the Galactic Patrolman that the Galactic Patrol can punish this kind of crime.
