Title: "What is the Shape of the Universe?"
Abstract: This presentation makes an elementary case for the universe being a hypersphere, S3. Higher dimensions are introduced along with generalized definitions of spheres and balls. That the universe is a hypersphere then follows directly from the properties of S3 and what we know of the universe.
Audience level: This talk can be given to an advanced high school class or to college undergraduates.
Equipment needed: A PC with PowerPoint software, a projector and a screen.
Presenter: Prof. David Seppala-Holtzman
