網上講座 － 黑洞之形 | Online Lecture － The Shape of Black Holes
談天說理：天文物理新知網上講座系列 （香港中文大學物理系與香港太空館合辦） 黑洞之形 （英語講解） 黑洞引力之大，所有物質，甚至連光都無法逃離黑洞；人類要如何才能一睹這神秘天體的面貌呢？隨著科學家在2015年首次探測到由兩個黑洞撞擊所引起的重力波，重力波為探索黑洞和宇宙帶來更多珍貴的新發現。是次講座中，我們將利用重力波，看見黑洞及了解其神秘的特性。 講者：黎冠峰教授（香港中文大學物理系助理教授）及 Prof. Juan Calderon Bustillo（香港中文大學物理系研究助理教授） 講座日期及時間：2020年4月4日 下午2:30 － 3:30 Physics of the World Beyond - Frontiers in Astrophysics Online Lecture Series (Jointly Organised by the Department of Physics, The Chinese University of Hong Kong and the Hong Kong Space Museum) The Shape of Black Holes (Conducted in English) What do black holes tell us about the Universe? How can we see them, if not even light can escape black holes? After a hundred years of studying black holes, how much do we know now about the most elusive objects in the Universe? In 2015, scientists discovered ripples in the fabric of spacetime from the violent collision of two black holes, now known as gravitational waves. These gravitational waves, detected by kilometre-scale detectors around the world, give a rare insight into black holes and the Universe. In this lecture, we will show how gravitational waves are used to "see" black holes and study their enigmatic properties. Speakers: Prof. Tjonnie Li (Assistant Professor, Department of Physics, The Chinese University of Hong Kong) and Prof. Juan Calderon Bustillo (Research Assistant Professor, Department of Physics, The Chinese University of Hong Kong) Lecture Date and Time：4 April 2020 2:30 － 3:30 p.m.
