How much do you know about our cosmic existence?
The universe is literally everything, the sum of all existence. It includes all matter, like stars and galaxies. The universe also includes all radiation and all other forms of energy. No matter where or when you exist, you are a part of the universe, as is everything you experience. There is nothing outside the universe, because anything that exists is automatically included in the definition of the universe.
How was the universe created?Scientists do not know what came before the Big Bang. However, they do know that the singularity is not real; instead, it's an artifact of general relativity that occurs when the equations break down and lose their ability to describe a physical situation. A true explanation for the singularity must lie in a theory of quantum gravity, which is a physical theory of strong gravity at extremely tiny scales.
The galaxies that astronomers observe at the very edge of this sphere released their light up to 13 billion years ago. However, the universe is expanding faster than the speed of light, which is not an issue, because special relativity dictates that the restriction that objects can't travel faster than the speed of light applies only measurements made nearby an observer, not to objects in the distant universe.
However, one size estimate comes from the theory of inflation, an event many cosmologists think occurred during the earliest moments of the Big Bang. During inflation, the universe rapidly swelled to many orders of magnitude larger in a tiny fraction of a second. Inflation theory puts the minimum size of the universe at around 10^62 times wider in diameter than the observable universe.
The remaining 5% of the universe consists of normal, familiar matter, like stars, planets and vast gas clouds. Additional resourcesBibliographyBrennan, P. . NASA. https://exoplanets.nasa.gov/what-is-an-exoplanet/what-is-the-universe/
