Cosmology: The shape of the Universe
George F. R. Ellis1
Abstract
An analysis of astronomical data suggests not only that the Universe is finite, but also that it has a specific, rather rigid topology. If confirmed, this is a major discovery about the nature of the Universe.
What shape is space? On page 593 of this issue, Luminet et al.1 suggest that the topology of the Universe may be a 'Poincaré dodecahedral space' — as illustrated on this week's cover.
