The Big Bang Theory is an explanation for the beginning of the universe. The universe today is expanding, as can be seen in the way all matter is moving outward. Tracing this movement back through time takes all matter to a single point, leading to the view that at one time all matter was concentrated in a singularity which for some unknown reason exploded, throwing all material now seen in the universe outward from that central point. There are various corollaries to this theory, such as the issue of whether the expanding universe will continue to expand forever or will eventually reach an end point and fall back on itself. There are also various consequences of the Big Bang which can be used to determine if the theory has validity. A number of researchers have examined aspects of the Big Bang theory and developed ideas related to it (DO NOT USE THIS IT IS SOME ONE ELSES PAPER) The theory asserts that our entire universe was created when a tiny (billions of times smaller than a proton ), super- dense, super-hot mass exploded and began expanding very rapidly, eventually cooling and forming into the stars and galaxies with which we are familiar. This event is said to have happened approximately 15 billion years ago. Rather than expanding outward into some preexisting vacuum, the event of the Big Bang was space itself expanding - perhaps at speeds greater than light. (While Einstein 's theory of relativity forbids anything within space from travelling faster than light, it sets no limitations on how fast the fabric of space itself may expand.) http://www.wisegeek.com/what-is-the-big-bang-theory.htm THE BIG BANG One of the most persistently asked questions has been: How was the universe created? Many once believed that the universe had no beginning or end and was truly infinite. Through the inception of the Big Bang theory, however,no
