Paper Abstract:
Examines arguments attempting to support or discount theory of the origins of universe.
Paper Introduction:
BACKGROUND
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 r

The entire text of the paper is shown below. However, the text is somewhat scrambled. We want to give you as much information as we possibly can about our papers and essays, but we cannot give them away for free. In the text below you will find that while disordered, many of the phrases are essentially intact.
