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. 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.

Is The Universe Infinite Or Is It Just Really Big?
The global geometry of the universe is in principle as observable an attribute as local curvature. Previous studies have
established that if the universe is wrapped into a flat hypertorus, the simplest compact space, then the fundamental domain must be at
least 0.4 times the diameter of the observable universe. Despite a standard lore that the other five compact, orientable flat spaces are more weakly constrained, we find the same bound holds for all. Our analysis provides the first limits on compact
cosmologies built from the identifications of hexagonal prisms.

[...] There was once a cultural prejudice that the Earth was flat and unconnected, so much so that explorers were feared to have fallen off the edge. The assumption that space must be infinite may represent a similar bias. Just as most have realized that our planet is compact, we may someday learn that
the entire universe is likewise compact and connected. [...]

Conventional thinking says the universe is infinite. But it could be finite and relatively small, merely giving the illusion of a greater one, like a hall of mirrors. Recent astronomical measurements add support to a finite space with a
dodecahedral topology.

Das Universum als "Fußball"! Na das könnte manchen gefallen....
BTW: Ich hab dir das jetzt nur schnell rausgesucht. Ich hab mir das noch nie selbst im Detail angeschaut, ich verfolge auch
das Thema nicht.
