아래와 같이 콜로퀴움을 개최하오니 많이 참석해 주시기 바랍니다. 아 래 1. 제목: What has happened in the beginning of the universe? 2. 연사: 김 상 표 교수(군산대학교) 3. 일시: 2006년 10월 13일(금요일) 오후 4시 30분 4. 장소: 물리학과 세미나실(31355호실) 5. 초록: The origin of the universe has been an issue of important concern in science and philosophy for many centuries. At the beginning of twenty century our universe was supposed to be static, never changing in time and space. Einstein's general relativity is the right theory to describe the universe from the beginning to the end. However, based on the contempoary data Einstein proposed a universe model with a cosmological constant to explain the static universe. In nineteen twenties Hubble observed the expansion of the universe. Since then it has been known that our universe has expanded according to the Friedmann equation, an Einstein equation for the universe. Dated backward in time the universe would have started from a small volume or primordial universe or big bang singularity. In this talk the origin of the universe is reviewed from various current theories such as quantum cosmology, loop quantum gravity, string theory. And then some hot issues such as inflation and thermalization in the early universe will be explained.
