Astro 1 Section 1 Professor Brandt Friday March 26th 1999 Announcements: Lecture notes: Class 30. Today will start talking about cosmology. Cosmology - the study of the structure and evolution of the universe on the largest size scales and over the longest times. Cosmology is active field of research where many ideas are still charging fairly rapidly - scientists are generally less certain about the material in this part of the course than about stars galaxies etc. The rapid changes lead to confusion sometimes. Newspapers "crisis in cosmology" e.g. people worked out age of universe but were finding that globular clusters appeared to be older than universe etc. I will focus on the things about cosmology that are relatively certain. In particular we will talk about the Big Bang and the 3 pieces of evidence that support it most strongly. Expansion of the Universe. Primordial nucleosynthesis Cosmic microwave background. The 3 pillars of the Big Bang cosmology.
