What is the Big Bang?

A theory that the universe formed in a huge explosion


What is one of the primary unaswered questions about the origin of the universe?

It was what came before the big bang, and the big bang theory states that the universe started as a dense nucleus of matter: a huge amount of matter concentrated in a tiny spot. This is the conclusion of equations and evidences that prove that the universe has been and continuous to expand: since it has been expanding, there was a moment when it was as small and dense as it is possible . So, the expansion is the result of violent explosion. The time during which the expansion has been happening (this is how long ago the big bang occurred) has been estimated thanks to the observation of the speed of recession of the galaxies, but nothing can be told about what came before the big bang occurred .


Did the big bang give us light?

The Big Bang did not give us visible light. Light, from the time of the Big Bang has been red shifted so that it is now in the microwave part of the spectrum.However, the Big Bang did give us all the matter that exists, and some of that matter formed stars which, in their nuclear fusion, produce light.
