Detailed explanation-1: -The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe.
Detailed explanation-2: -The Universe is thought to consist of three types of substance: normal matter, ‘dark matter’ and ‘dark energy’. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.
Detailed explanation-3: -It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest-everything on Earth, everything ever observed with all of our instruments, all normal matter-adds up to less than 5% of the universe.
