Why do we need to know about the Big Bang?
We must study the Big Bang and the history behind it because the past is all around us every day. The conditions that the Big Bang left the Universe will shape the future. We can study further real world applications that relate to the Universe from the event of the big bang by answering some of the questions that still linger. Inflation is one of the major instances that occurred during the big bang. During the first few mili seconds after the event, the Universe increased rapidly and is still expanding; but at a much slower rate. Will the universe continue to expand, or will it shrink back to a point in space?
