A relativistic model of the topological acceleration effect
Jan J. Ostrowski, Boudewijn F. Roukema, Zbigniew P. Bulinski
It has previously been shown heuristically that the topology of the Universe affects gravity, in the sense that a test particle near a massive object in a multiply connected univer…
Poincare dodecahedral space parameter estimates
Boudewijn F. Roukema, Zbigniew Bulinski, Nicolas E. Gaudin
We aim to improve the surface of last scattering (SLS) optimal cross-correlation method in order to refine estimates of the Poincaré dodecahedral space (PDS) cosmological parameter…
The optimal phase of the generalised Poincare dodecahedral space hypothesis implied by the spatial cross-correlation function of the WMAP sky maps
Boudewijn F. Roukema, Zbigniew Bulinski, Agnieszka Szaniewska +1
Several studies have proposed that the shape of the Universe may be a Poincare dodecahedral space (PDS) rather than an infinite, simply connected, flat space. Both models assume a…
