Title: Dark Matter Is Everywhere  暗物质无处不在

What is it about? 

The dark matter theory assumes the existence of invisible matter in galaxies and predicts that its mass is much greater than the total mass of visible stars. The make-up of dark matter remains a mystery as it cannot be detected directly. A real-particle (r-particle) field theory proves that dark matter is composed of real-electrons (r-electrons). A gas of r-electrons is ubiquitous throughout the universe. The visible heavenly bodies cruise in an ocean of dark particles, just like humans living in the air and fish swimming in the water.   暗物质理论假设星系中存在不可见物质并预言其质量远大于可见星体的总质量。因为无法直接探测，暗物质的成分是个未解之谜。实粒子（r-粒子）场论证明，暗物质成分是实电子（r-电子）。r-电子气体布满宇宙、无处不在。可见的天体游弋于暗粒子海洋，如同生活在空气中的人类和游动于水中的鱼类。

Why is it important?

Known particles include electrically charged e-particles and uncharged r-particles. There exist density fields (mass density ρ and momentum density j) in the space full of r-particles. The spatial convolutions of densities result in potential fields (mass potential F and momentum potential A), and the spatial derivatives of potentials result in action fields (gradient G, curl C, and divergence D). The second-order spatial derivatives of potentials satisfy the equations similar to those of electromagnetic field, and the second-order spatial derivatives of actions satisfy a set of Poisson equations. It is demonstrated that charge and mass have an equivalent relationship, and the laws of classical mechanics and electrodynamics are inferences or limit cases of r-particle field theory.    已知的粒子包含带电荷的e-粒子和不带电荷的r-粒子。在布满r-粒子的空间中存在密度场（质量密度ρ和动量密度j）。密度场的空间卷积产生势场（质量势Φ和动量势A），势场的空间导数产生作用场（梯度G、旋度C和散度D）。势场的二阶空间导数方程组与电磁场方程组相似，作用场的二阶空间导数满足一组泊松方程。业已证明，电荷与质量具有等价关系，经典力学和电动力学的定律都是实粒子场论的推论或特例。

Perspectives

Dark particles make up the cosmic background, and dark energy comes from the motion of dark particles. The dark particles have an extremely high density (10²⁴ m^-3) and an extremely low mass density (10^-7 kg×m^-3). The r-electrons are the medium for transmitting the gravitation and light waves and are also the components of visible matter. The prediction of omnipresent r-electrons is one of the exemplars of r-particle theory.   暗粒子形成宇宙背景，暗能量来自暗粒子的运动。暗粒子的数密度很大（10²⁴ m^-3），质量密度很小（10^-7 kg·m^-3）。r-电子是传递引力和光波的介质，也是构成可见物质的成分。预言无处不在的r-电子是实粒子理论的范例之一。
