摘要：

We investigate the behavior of light rays in an open universe with a partly periodic horn topology. The geodesics can be solved exactly and the periodic topology creates characteristic new effects in temperature maps of the microwave background. Large flat regions appear in Cosmic Background Explorer sky maps even when multiple images of astronomical sources are unobservable.
