If space is compact, then a traveller twin can leave Earth, travel back home without changing direction and find her sedentary twin older than herself. We show that the asymmetry b…
New Developments in the Search for the Topology of the Universe
Jean-Philippe Uzan, Roland Lehoucq, Jean-Pierre Luminet
Multi-connected Universe models with space idenfication scales smaller than the size of the observable universe produce topological images in the catalogs of cosmic sources. In thi…
Limits of crystallographic methods for detecting space topology
Roland Lehoucq, Jean-Philippe Uzan, Jean-Pierre Luminet
We investigate to what extent the cosmic crystallographic methods aimed to detect the topology of the universe using catalogues of cosmic objects would be damaged by various observ…
