Brian Cox: Something Terrifying Existed Before The Big Bang

Big bang is the contemporary cosmological theory that explains the creation and change of the universe. Based on this model, the big bang occurred about 13 billion years ago and this is the moment when the universe started. It took about 13. 8 billion years and it emerged from an initial state of singularity, a dense and hot point also referred to as the Big Bang. This expansion led the development of subparticulate formation and initiation of simple atomic structure that led to the formation of stars and galaxies.

There are key proofs for Big Bang theory such as cosmic background radiation which is the heat or light from explosion and the second proof is red shift of far away galaxies showing that the universe is still expanding. This theory not only explains the evolution of the universe in the past, it also gives a concept of what should happen to it in the future, and this is that the universe will go on expanding ad infinitum.

The Big Bang has revolutionized our perception of the universe and has given the world a plausible explanation of how the universe was created and has developed over the space of billions of years.
