| Title of Talk | The Edge of the Universe--Hyperbolic Wallpaper |
| Abstract | The universe couldn't have an edge, because if it did, you could go there, put your hand through and find more of the universe on the other side, right? This reasoning breaks down if you and your measuring devices shrink as you approach the edge, making it infinitely far away. We show a mathematical model of such a universe, called the Poincare Upper Halfplane, and study some of its features. The classical topic of circle inversion plays a prominent role. Physics suggests that this turns out to be a cold and lonely place, but we make beautiful wallpaper for the inhabitants. |
