Ia型超新星測距揭示宇宙的命運——2011年諾貝爾物理學獎簡介
發(fā)布時間:2019-03-06 08:18
【摘要】:2011年度諾貝爾物理學獎授予了在天體物理研究領域取得杰出成就的美國科學家索爾.波爾馬特、擁有美國和澳大利亞雙重國籍的科學家布賴恩.施密特以及美國科學家亞當.里斯。他們通過Ia型超新星測距發(fā)現(xiàn)宇宙的膨脹是加速的,從而揭示了暗能量的存在。筆者將對人類認識宇宙的過程、Ia型超新星與宇宙加速膨脹、暗能量以及Ia型超新星研究中存在的問題做全面的介紹,并介紹中國學者在該領域的研究進展。文章的最后做了展望。
[Abstract]:The 2011 Nobel Prize in Physics was awarded to an American scientist who has made outstanding achievements in the field of astrophysics. Bormatt, a scientist with dual American and Australian citizenship, Brian. Schmidt and American scientist Adam. Reese. They discovered that the expansion of the universe was accelerated by Ia-type supernova ranging, thus revealing the existence of dark energy. The author will give a comprehensive introduction to the process of human understanding of the universe, the accelerated expansion of the universe, the dark energy and the problems existing in the study of the type Ia supernova, as well as the research progress of Chinese scholars in this field. The last part of the article makes a prospect.
