Cosmic Topology


The Poincare dodecahedral space better explains the WMAP 3 year observations than the infinite flat model. RBSG08 image We proposed a method that involves a cross-correlation function - this uses more information than the original identified circles method. An optimal cross-correlation appears to be a stable solution, and finds a twist angle of close to +36 degrees.

theoretical work

The Poincare dodecahedral space is much better balanced, in the sense of the interaction between topology and gravity called the residual gravity effect, than other spaces.
