Quantum Fields in Curved Space N. D. Birrell, P. C. W. Davies
Publisher: Cambridge University Press

Spacetime analogs is an emerging field of physics in which scientists investigate systems having mathematical links with general relativity, and test their theories about the early behavior of the universe. Gravitation: the medium of exchange is the metric of space-time itself. Since there is no complete quantum theory of gravity, they used an already well-accepted approach, called quantum field theory in curved space time(QUIETS). Gravitons are virtual excitations of the curvature of space-time, treated as a quantum mechanical field. Despite of it, the combination of four-dimensional general relativity and quantum mechanics theories can describe some aspects of five-dimensional reality like the small curved patches, which are used for paving of rough surface.
