Nothing

Nothing, no-thing, or no thing is the complete absence of anything, as the opposite of something and an antithesis of everything. The concept of nothing has been a matter of philosophical debate since at least the 5th century BCE. Early Greek philosophers argued that it was impossible for nothing to "exist". The atomists allowed nothing but only in the spaces between the invisibly small atoms. For them, all space was filled with atoms. Aristotle took the view that there exists matter and there exists space, a receptacle into which matter objects can be placed. This became the paradigm for classical scientists of the modern age, like Isaac Newton. Nevertheless, some philosophers, like René Descartes, continued to argue against the existence of empty space until the scientific discovery of a physical vacuum.
