## Course DescriptionWhat do we mean by "curved spacetime"? As you freely fall toward a black hole, how long does it take to reach the event horizon according to your watch? Can your friend at a safe distance actually see you cross the horizon? What happens at the horizon? Can you receive messages and packages from your friend on the outside? Can you send messages to your friend on the outside? How quickly will it be over at the central crunch point?You can answer these questions for yourself with some math, starting from a simple formula, the "metric," for the black hole. You can also answer every possible question about trajectories of light and satellites around the black hole as well as around familiar centers of gravitational attraction such as the Earth and Sun. Also, there is the metric describing the entire universe. The metric tells us how the universe expands and ends. SYLLABUS: The course begins by examining the idea of spacetime curvature and the Schwarzschild metric for a non-rotating black hole. With the metric we calculate the circumferences of circles in space around a large mass and find they do not match up with their radii in the usual way. As in special relativity, we find that observers disagree in startling ways, but general relativity even puts limits on our ability to construct reference frames in which to study these effects. We will calculate the consequence of spacetime curvature outside and inside a Schwarzschild black hole, Hawking radiation, and rotating black holes. We will learn the Big Bang, forms of energy driving the expansion of the universe, and cosmological models. Depending on time (and interest) we may cover gravitational waves. NOTE: Participants should have good math skills, especially in calculus. They should know how to find a maximum and a minimum of a function and should be able to integrate polynomial functions. Also, participants need to be familiar with quantization of light energy (Planck relation), Heisenberg uncertainty principle, time dilation, length contraction, relativistic energy, and other basic principles in modern physics. Some knowledge of astronomy would be helpful.
## Meeting Place and TimesTeachers log into the course at a time of day that best fits their schedule. It is necessary to connect at least 4 - 6 times per week and spend 9 - 12 hours each week while the course is in session, either online or offline working on course related assignments, to stay current and successfully complete this 3 credit graduate course. ## Instructor(s)Tsunefumi Tanaka, PhD. After graduating from Montana State University in 1997, I taught physics and astronomy at universities in Virginia and California for 9 years before moving to New Zealand. I'm back in the US, and I'm currently teaching at University of Puget Sound. I began studying physics because I was interested black holes, astrophysics, and cosmology although my doctoral thesis was actually in quantum field theory. I like typical geeky stuff such as SciFi, computers, and aquarium. I also enjoy cycling, hiking, and fishing. I am an avid amateur astronomer; I miss clear sky in Montana. We got too many rainy nights in Tacoma.## PrerequisitesOne year of College Physics; Differential & Integral Calculus; an Introductory Modern Physics course is preferred but as long as participants are familiar with basic principles of modern physics they should be okay; and Special Relativity such as the NTEN course SPECIAL RELATIVITY.## Target AudienceThis course is designed primarily for high school science teachers.## Time Commitment:9-12 hours per week. If you are unfamiliar with this field of study and/or method of delivery, you may require more time.## Tuition and Fees

Teacher/participants are responsible for purchasing the required texts for the course on their own before the course begins. ## Computer Requirements:- Computer running Windows XP Service Pack 3 or newer or Mac OS X.5 (Leopard) or higher
- CD-ROM drive
- Internet access
- Access to the equation editor in Word is very helpful but not required. Problem sets are templates you download and you type your solutions directly on the template. We ask you to show your work which can be difficult without an equation editor. Scanning your hand work and submitting as .pdf files is acceptable.
