# The Copernican principle in compact space–times

@article{Barrow2003TheCP, title={The Copernican principle in compact space–times}, author={John D. Barrow and Janna J. Levin}, journal={Monthly Notices of the Royal Astronomical Society}, year={2003}, volume={346}, pages={615-618} }

Copernicus realized that we are not at the centre of the Universe. A universe made finite by topological identifications introduces a new Copernican consideration: while we may not be at the geometric centre of the Universe, some galaxy could be. A finite universe also picks out a preferred frame: the frame in which the universe is smallest. Although we are not likely to be at the centre of the Universe, we must live in the preferred frame (if we are at rest with respect to the cosmological…

The topology of extra dimensions can break global Lorentz invariance, singling out a globally preferred frame even in flat spacetime. Through experiments that probe global topology, an observer can…

Point particle motion in topologically nontrivial space-times

It is well known that compactifying a space can break symmetries that are present in the covering space. In this paper we study the effects of such topological symmetry breaking on point-particle…

We discuss the problem of the stability of the isotropy of the universe in the space of ever-expanding spatially homogeneous universes with a compact spatial topology. The anisotropic modes which…

Can COBE see the shape of the universe

- Physics

In recent years, the large angle COBE-DMR data have been used to place constraints on the size and shape of certain topologically compact models of the universe. Here we show that this approach does…

Periodic boundary conditions in special relativity

The imposition of periodic boundary conditions on the space‐time of special relativity is shown to lead to the existence of a preferred frame of reference. One characteristic of the preferred frame…

Twins travelling at constant relative velocity will each see the other's time dilate leading to the apparent paradox that each twin believes the other ages more slowly. In a finite space, the twins…
