The universe

The universe was commonly defined as the totality of everything that exists, including all space, time, matter, energy, planets,stars, and all galaxies including the Skyriver galaxy in which took place the Celestial War, The Hyperspace Wars, The Sith Wars, Clone Wars, The Galactic Civil War, The Yuuzhan Vong War, The New Imperial war and beyond. Definitions of the universe varied and similar terms included the cosmos and the world and nature. Scientific observations of earlier stages in the development of the universe suggested that the universe has been governed by the same physical laws and constants throughout all time. There are various multiverse theories and many beings suggested the universe was one among many universes that likewise exist.

History and exploration
Throughout recorded Galactic history, even before many species mastered space travel, several theories have been proposed to account for observations of the universe. Over the countless millenia, beings from many worlds have grown to understand the universe in greater depth.It is uncertain whether the universe has an end or not, but scientific study proves that if it does have a boundry, it is definitely growing. Many baings speculate that there may be other universes out there, which could be reached via dimensional travel. The universe has never been fully explored by any race, mainly due to its incomprehensable size that dwarfs even the largest galaxies.

Size
The universe is immensely large and possibly infinite in volume. The region visible from most planets in the Skyriver Galaxy (the observable universe) was a sphere with a radius of about 46 billion light years. For comparison, the diameter of a typical galaxy is only 30,000 light-years, and the typical distance between two neighboring galaxies is only 3 million light-years. There are probably more than 100 billion galaxies in the observable universe. Typical galaxies ranged from dwarfs with as few as ten million stars up to giants with one trillion, all orbiting the galaxy's center of mass. Thus, a very rough estimate from these numbers would suggest there were around one sextillion stars outside the Skyriver Galaxy in the observable universe. The observable universe was only a small part of the actual universe, which was said to be infinite. Despite the fact that all beings in the Galaxy only knew normal matter, the Universe was said to be comprised of dark matter, a substance invisble to all light.

Creation
Befor the universe began there was a huge battle between particles of matter and particles of antimatter. In the end, matter gained the upper hand due to greater numbers. After antimatter was destroyed, the universe was created through the biggest explosion ever, known to science as "The Creation" or "The Beggining" or "The Big Bang". In that moment, all the laws of physics, including the living force, were created. Despite many claims, there is still antimatter in the universe. Due to this, scientists claimed that there was another dimention madde of antimatter which mirrored the universe.
