baryonic matter

基本解释

Baryonic matter: In this cosmological context, this is "ordinary matter" composed primarily of protons, neutrons and electrons.
重子：這是“傳統物質”，主要由質子，中子和電子組成。
Recent astronomical observations show that only about 5% of the Universe were made of the baryonic matter which we understand, about 25% were dark matter, and the rest 70% were dark energy.
近年來的天文觀測表明，宇宙中衹有約5%的物質是我們所了解的重子物質，其餘約25%是暗物質，約70%是暗能量。
Dark matter: this generally refers to "exotic" non-baryonic matter that interacts only weakly with ordinary matter.
暗物質：這一般是指“外來的”非重子物質，與普通物質衹有較弱的的相互作用。
