Guidance Sheet #1 - 06/18/96

This is the first of four guidance sheets we will be handing out. Its main purpose is to give you a preview of what is going to be covered in the next two weeks and to help you distinguish the important points from the minor details. You can also use these sheets for studying for the quizzes. To help us get an idea about what your background knowledge is, you will have about 10 minutes to try to answer the questions on the guidance sheets before the material is covered in lectures and sections. You will not receive a grade for this, but you will be required to turn in your answers! Write them on a separate sheet of paper so you can keep the questions and use them as a reference during lectures and sections. You should try to work on all the questions, so keep your answers short!

1. How can you tell if the Universe is finite or infinite?
2. How do we measure the state of motion of the Universe? Which relationship do these motions obey?
3. What is the evidence for a Big Bang event?
4. What is the Cosmological Principle? Why do most cosmologists adopt it for their models of the Universe?
5. What is the attractive aspect of the Steady State Theory? Name one reason why it is no longer accepted by cosmologists.
6. How is it possible to have a finite Universe without any "edge"?
