What is universe?</h3>
The term "universe" (from the Latin "universus") refers to the entirety of space, time, and all of its objects, including galaxies, planets, stars, and other types of matter and energy. The prevailing cosmological explanation for the universe's formation is the Big Bang theory. This hypothesis states that the universe has been expanding ever since the Big Bang, which took place 13.7870.020 billion years ago. While it is uncertain how big the entire universe is in terms of space, it is possible to calculate the size of the observable universe, which has a current diameter of about 93 billion light-years.
Early cosmological conceptions of the cosmos were geocentric, with Earth as the centre, and were created by Greek and Indian philosophers.
