The primary focus of this paper is on a connection between imaginary nothing and real nothingness; as the paper reveals, that insight allows us to bridge real physical entities and imaginary mathematical concepts in a manner that may be considered consistent with both causality and complementarity. What makes this nexus extremely relevant to natural philosophy is that it is amenable to addressing in terms of analytical solutions: such construct allows us to interpret asymmetry and symmetry, causes and effects, continuous and discrete, entropy and gravity, matter and time, and other fundamental complementarities in terms of a common conceptual framework. Of interest to broader audience is that that framework suggests that the laws that determine physical conservation and the laws that ensure survival of sentient beings derive from the same logical pattern and obey the same conservation principles.
