Negatively Curved Crystals

Cabot Discovery Bar

Imagine the Universe is a periodic crystal. If gravity makes space negatively curved, the thin walls of the crystalline structure might trace out a pattern of circles in the sky, visible at night. In this talk we will describe how to generate pictures of these patterns and how to think like a hyperbolic astronomer. The lecture is accompanied by a exhibit of posters in the Science Center colonnade.
