About Universe: Cosmos, Multiverse, Expansion of the Universe and its Size
What is the universe?
The universe is the space around a given body including all living and non-living things Like the planet, galaxy, stars, and all other forms of matter and energy.
This is already known that Earth is just a tiny ball in an incredibly enormous vacuum and that the birth of the solar system was actually only one of many events in an already complex existing universe.
For some multiverse concepts our world (universe) is one of the causally-disaggregated components of a broader multiverse that contains both time and space and content as a consequence, "the cosmos" and "the multiverse" signify in these theories.
The word cosmos rather than the word universe implies viewing the universe as a complex and orderly system or entity, the opposite of chaos.
What is the size of the Universe?
Though the size of the universe is not known astronomers estimate that it is composed of approximately 100 billion galaxies where each galaxy contains about 100 billion stars.
Also with the concept of expanding the universe, it also complexes to estimate the size of the universe at any time.
Expanding Universe
According to the Expanding universe, theory universe is expanding in all directions and all galaxies are going apart from each other. this expansion is happening in all direction so the observer feels the everything same as earlier.
