Big Bang Theory Universe Expanding The big bang theory. the big bang theory is the prevailing cosmological model for the universe’s birth. it states that 13.8 billion years ago, all of space was contained in a single point of very high density and high temperature state from which the universe has been expanding in all directions ever since.

Big bang theory is about the origin of the universe. it suggests that about 1370 crore (13.7 billion) years ago, all matter and energy in the universe was concentrated in an area smaller than an atom. at this instant, matter, energy, space, and time were not existent. then suddenly with a bang, the universe began to expand at an incredible rate. The big bang theory explains the early development of the universe. according to this theory, the universe expanded from an extremely small, hot, and dense state called singularity. since then, it has expanded and become less dense and cooler. the big bang is the best model to explain the creation of matter, space, and time 13.7 billion years ago.

The Stages Of The Formation Of The Universe Big bang theory is about the origin of the universe. it suggests that about 1370 crore (13.7 billion) years ago, all matter and energy in the universe was concentrated in an area smaller than an atom. at this instant, matter, energy, space, and time were not existent. then suddenly with a bang, the universe began to expand at an incredible rate. The big bang theory explains the early development of the universe. according to this theory, the universe expanded from an extremely small, hot, and dense state called singularity. since then, it has expanded and become less dense and cooler. the big bang is the best model to explain the creation of matter, space, and time 13.7 billion years ago. The universe is very old – almost 13 billion years old. huge clusters of galaxies comprise the universe. the big bang theory attempts to explain to us the origin of universe. it talks of a singular huge explosion unimaginable in physical terms. the universe expanded and hence, the temperature came down. hydrogen and helium formed sometime later. The big bang theory considers the following stages in the development of the universe. in the beginning, all matter forming the universe existed in one place in the form of a “tiny ball” (singular atom) with an unimaginably small volume, infinite temperature and infinite density. at the big bang the “tiny ball” exploded violently. this.
