A double dose of cosmic considerations, presented by the first undergraduate guest speaker in this series! Begin with the simple, yet deep, question of "why is the night sky dark?" This classic conundrum was raised two centuries ago because it directly conflicts the assumption of an infinite, eternal, and static universe. Then, probe further into last summer's total solar eclipse. While the view of the Sun changed spectacularly, the rather subtle change in view of the stars behind the Sun reflected a grander geometric property rooted in gravity and the nature of space time. Join us for some delightful deliberations of our intriguing universe.
