Why Is There Something Rather than Nothing?

The main objective of this study is to make a comprehensive analysis of the question “Why is there something rather than nothing?” which is one of the major questions of metaphysics and to find a plausible answer at the end if it is possible. To begin this analysis a clarification of what we understand by this question is needed first. For the clarification a definition of ‘nothingness’ will be sought. Afterwards the motivation for us to ask this question the significance of it and the content of it will be investigated. This investigation will help us concentrate on and discuss within the framework of causation and necessity our understanding of “contingent beings” and “nothingness”. Two main approaches sought to answer this question till now are by theists and physicists. Those approaches will be discussed and compared. And at the end of the comparative analysis of these two approaches a metaphysical approach which will be a layer of them will be sought.
