We show that a compact spacetime of a single particle in a space-time manifold can be constructed by taking the double-trace to be the world-volume of the space-time manifold. We discuss some properties of the compact spacetime and the compact spacetime geometry. We also discuss some aspects of the compact spacetime geometry.
