WMAP First Year Sky Map: Hints of Poincare Dodecahedral Topology

摘要

Several analyses of the cosmic microwave background map made by the satelliteWMAP suggest that the global shape of a spatial section of the Universe is thatof a Poincare dodecahedral space. A summary of some of these analyses and adescription of independent tests which should be able to either increaseconfidence in the hypothesis or else refute it to extremely high significancewill be presented.
