The Cosmos

The Cosmos is a terminology often used to refer to a single universe's outerspace (or equivalent), however has seen far greater usage beyond Universes, quickly to become Meta-Cosmological.

Formation
It is unknown how EXACTLY a universe is created, however often times it is theorized to be created by a "Big Bang" effect, or a Godly being creating it using their power. Sometimes, these are simulatenous, but it has been debated if such is possible, as both at different causes with the universe being a effect. Moreover, The Designer itself was born by The Ancestor, where the designer singlehandedly ended a Supercivilization by making landfall. This created the Main Universe of Star Spectrum (hereby referred to as simply "the universe"), by destroying what remained of the Supercivilization in a violent explosion, that would later become known as the Big Bang. Subsequently, everything necessary for the universe's creation was formed, aswell as other important substances, materials, and more such as Dark Matter, Dark Energy, Gasses, Normal matter, Hydrogen, Helium, Oxygen, Light and far, far more. Universes can vary in size, some may be limited in size, some may expand infinitely, and some may be equivalent to multiple universes in one via multiple different planes of reality or realms that are large enough to estimate this - the last of which are known as Macrocosms. From there, Stars formed from Gas, due to gasses falling into galaxies due to Gravitational effects. However, some gas may not have the chance or time to form Stars if the galaxy's centered Supermassive Black Hole or Exploding Stars exert too much energy into the gas, prematurely ending the star. to correctly create Galaxies, the right amount of energy that the gasses contain might be key, as there can be lots of, or few stars by the end, all by the amount of energy given to the gasses forming stars. The energy of which a Black Hole has helps in that they can remove gas or add heat to them. If the energy of a black hole is too low, it can create too many galaxies with lots of stars, whilst if it were too high they'd create a low amount of galaxies with too many stars. As such, a generally medium, balanced amount of energy is generally the most common. Resultingly, some galaxies have lots of stars while others have very little. Aquiritis is one of the first Galaxies, however a exact estimate for it's age is unknown, though some believe it may have been the first. Stars are only able to form if they can cool down enough that their gasses clump together. If the balance of Gravity, which itself is mostly from Dark Matter, and the Energy Injection from Black Holes are incorrect, the numbers may not be correct. Larger Stars tend to live Shorter Lives, ending abruptly in bright explosions called Supernovae, that can sometimes even be seen several thousands of lightyears away, out of their sheer brightness. When a Supernova event occurs, it helps to control the rate that newer stars are created via heating gasses. Additionally, a Supernova pulverizes Planets, Asteroids, Moons, and other materials if they have not flung away far enough in time after their star loses it's Gravitational Field that made them orbit or change direction. Kentchin, notably, seems immune to it's effects as demonstrated by a single meter of it taking the entire incinerating heat of the Sun, as well as notably being found near supernovae. A Star that went Supernova may collapse into a Black Hole or simply burn away, whereas a Supernovae may also disperse or become a Nebula.
