在宇宙学中,暗物质(dark matter)又称为暗质,是指无法通过电磁波的观测进行研究,也就是不与电磁力产生作用的物质.人们目前只能通过重力产生的效应得知,而且已经发现宇宙中有大量暗物质的存在.
现代天文学通过重力透镜、宇宙中大尺度结构的形成、微波背景辐射等研究表明:我们目前所认知的部分,即重子(加上电子),大致占宇宙的4%,而暗物质则占了宇宙的23%,还有73%是一种导致宇宙加速膨胀的暗能量.暗物质的存在可以解决大爆炸理论中的不自洽性,对结构形成也非常地关键.暗物质很有可能是一种(或几种)粒子物理标准模型以外的新粒子所构成.对暗物质(和暗能量)的研究是现代宇宙学和粒子物理的重要课题.
In astronomy and cosmology,dark matter is matter that neither emits nor scatters light or other electromagnetic radiation,and so cannot be directly detected via optical or radio astronomy.[1] Dark matter is believed to constitute 83% of the matter in the universe and 23% of the mass-energy.[2]
Dark matter was postulated by Fritz Zwicky in 1934 to account for evidence of "missing mass" in the orbital velocities of galaxies in clusters.Subsequently,other observations have indicated the presence of dark matter in the universe; these observations include the rotational speeds of galaxies,gravitational lensing of background objects by galaxy clusters such as the Bullet Cluster,and the temperature distribution of hot gas in galaxies and clusters of galaxies.Though the existence of dark matter is generally accepted by the mainstream scientific community,some alternative theories to explain the anomalies that dark matter is intended to solve have been proposed.
