Abstract:
Observations of microwave background fluctuations can yield
information not only about the geometry of the universe but potentially about the topology of the universe. If the universe is negatively
curved, then the characteristic scale for the topology of the universe is the curvature radius. Thus, if we are seeing the effects of the
geometry of the universe, we can hope to soon see signatur es of the
topology of the universe. The cleanest signature of the topology of the universe is written on the microwave sky: There should be thousands of
pairs of matched circles. These circles can be used to determine the precise topology and volume of the universe. Because we see hundreds of
slices through the fundamental domain of the universe, we can use the microwave observations to reconstruct the initial conditions of the
entire universe on the scale of a few megaparsecs.
