My work measures 1.75 meters by 1.75 meters and I modeled 32737 cubes, each cube representing a world, a domain. The name Three Thousand Worlds comes from a quote in the Buddhist scriptures, where three thousand means many. In the Creator's world, we are so small.
Space cosmology can also be divided into two branches. "'Vertical' describes the arrangement of worlds in a vertical pattern, with higher states of being in some worlds and lower states of being in others. On the other hand, in 'horizontal' cosmology, it describes and divides these vertical worlds into groups of thousands, millions or billions.
In vertical cosmology, the universe consists of many worlds, which one can call "planes", located on top of another world at a different level. Each world corresponds to a state of mind or state of being. However, a world is not necessarily in a physical location, because it is supported by the karma of its inhabitants, and if they all died or disappeared, the world would have the same end. Again, this world was born at the time of the first life.
