綱要Abstract/
進入21世紀後，科學家建造了大型雷射干涉儀重力波探測器，嘗試探測宇宙雙黑洞或雙中子星合併時所產生的重力波，這樣的重力波彷彿是一顆石頭丟入池塘所產生的水波漣漪向四面八方擴散。重力波所經過的時空發生了輕微的扭曲，導致雷射干涉儀的干涉路徑發生極微小的改變而展示出特殊的干涉圖案。在2015年9月14日，科學家首次成功量測到了這樣的重力波訊號，除了驗證了1916年愛因斯坦根據廣義相對論所給出的最後一個預言，更開啟一個全新的領域─重力波天文學，即將解開更多的宇宙未解之謎。
此次很榮幸邀請到 2015年諾貝爾物理學獎得主，日本東京大學宇宙射線研究所所長梶田隆章教授來台灣演講，他將介紹他所領導的日本重力波探測計畫KAGRA與重力波天文學的科學發展。
In the 21st century, large-scale laser interferometric gravitational wave detectors were built in the United States (LIGO), Europe (VIRGO), and Japan (KAGRA) with the aim of detecting gravitational waves which are ripples in space-time from the merging of black holes or neutron stars. Just like a stone dropped into a pond sends ripples across the water, gravitational waves spread across the universe and interact with these interferometers. It results in extremely small optical path differences between the interference arms and displays a special interference pattern. On September 14, 2015, the announcement by the LIGO and VIRGO collaborations of direct detection of gravitational waves confirmed Einstein's last prediction in 1916: the possible existence of gravitational waves. Now scientists have a completely new window opened to look at the universe and a new astronomy“gravitational wave astronomy”has been born.
It's our great pleasure to invite Professor Takaaki Kajita, the director of the Institute for Cosmic Ray Research of the University of Tokyo, who won the 2015 Nobel Prize in Physics for his discovery of neutrino oscillations, to give us a lecture at NCHU. He will introduce the gravitational wave detection project "KAGRA" and the science of gravitational wave astronomy in this precious lecture.
