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：这是“传统物质”，主要由质子，中子和电子组成。
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.
近年来的天文观测表明，宇宙中只有约5%的物质是我们所了解的重子物质，其余约25%是暗物质，约70%是暗能量。
Dark matter: this generally refers to "exotic" non-baryonic matter that interacts only weakly with ordinary matter.
暗物质：这一般是指“外来的”非重子物质，与普通物质只有较弱的的相互作用。
