dc.descriptionIf the Universe satisfies a perturbed Friedmann-Lema\^ıtre model, then the bright matter (e.g. radio-loud active galactic nuclei, RLAGNs) may be topologically lensed by global geometry. The generation of candidate topological lensing pairs of RLAGNs, which may be double images of single objects seen at very different celestial positions, provides very easily falsifiable (given moderate telescope time) cosmological geometry hypotheses.
