宇宙中充满暗物质,它是由最基本的粒子组成的。宇宙中所有的物质也都是由最基本的粒子组成的,包括原子核、电子、光子及电磁场。暗物质与空气相似,具有流体性质,符合流体力学原理,地球表面的暗物质密度ρ等于真空磁导率,其值为1.26 × 10−6 kg/m3,运用暗物质的流体性质可以说明很多物理现象,根据暗物质的特点提出了探测暗物质的方法。
The universe is filled with dark matter, which is made up of the most basic particles. All matter in the universe consists of the most basic particles, including nucleus, electrons, photons, and elec-tromagnetic fields. Dark matter is similar to air and has fluid properties. It conforms to the princi-ple of fluid mechanics. The dark matter density ρ of the earth’s surface is equal to the vacuum permeability, which is 1.26 × 10−6 kg/m3. The fluid properties of dark matter can explain many physical phenomena, according to the characteristics of dark matter suggest a method of detecting dark matter.
