Abstract Nature abhors an infinity. The limits of general relativity are often signaled by infinities: infinite curvature as in the center of a black hole, the infinite energy of the singular big bang. We might be inclined to add an infinite universe to the list of intolerable infinities. Many theories that move beyond general relativity naturally treat space as finite. In this review we discuss the mathematics of finite spaces and our aspirations to observe the finite extent of the universe in the cosmic background radiation.

• The dS/CFT Correspondence and the Big Smash (2001, background): “) Now of course this kind of advantage arises in many cosmologies with flat, compact spatial sections, but the problem is that, in the usual non-Phantom cosmologies, such non-trivial spatial topology has a definite signature, which has not been observed in the flat case [27].”
