宇宙中的暗物质是一种被称为“质量的黑暗”的物质，尽管它们目前还在科学研究领域遭到小看，但它们确实存在于令人难以置信的程度，盐掉一切明亮的物质的六十万倍以上。暗物质通常是一种未知的物质，这种物质与原子核和质子、中子没有明显的相互作用，但它确实拥有引力，它不能通过电磁波来观察，只能通过其重力作用来探测它的存在。
暗物质在恒星系统中扮演着重要的角色，因为它们分布在星系的大部分区域，是它们的核心的稳定的力。正是暗物质的重力吸引力，星系的形状和其他一些现象才能够被发现，而这些现象本身和暗物质有着千丝万缕的关联。
暗物质也是产生星系旋转曲线的原因之一。星系的旋转曲线实际上是指特定星系里所有恒星被暗物质重力吸引力驱使运动时，恒星们所贴出来的曲线。传统的旋转曲线假设星系中的暗物质不存在，只有可见的物质，这种曲线就会显得很不可靠，因此当考虑到暗物质的存在性以及其重力作用，旋转曲线就变得更加准确。这样，科学家们就可以得出星系中暗物质的重量、分布和影响，为进一步解释星系旋转力学提供了基础。
而暗物质，像特拉普卫星那样，还可能形成一个封闭的星系系统，即暗物质星球。暗物质星球从未被观察到，甚至无法被微波观测，它们只能通过对分布解释以及实验测量的重力力的作用而被发现。此外，由于暗物质星球没有可见的物质，它们也可以被称为“黑洞星球”，它们可能包括像特拉普卫星这样的矮小物体或更大的星体，它们可能和恒星或小行星群组一起组成一个健康的，安稳的星系系统。由于暗物质不会与可见物质产生相互作用，因此它们不会因为普通的物理现象而被消灭，反而更加稳定。
自从暗物质的发现以来，科学家们一直致力于解释暗物质实际上是什么，它们如何发挥重力作用，并影响宇宙中星系的形状和旋转曲线。根据现在的研究，暗物质也可能形成独立的星系系统，因此未来研究可能会持续探索暗物质星球及其在宇宙中的作用。
In the universe, dark matter is a kind of matter known as "the dark mass", which is still overlooked in the scientific research field, but it actually exists in an incredible level, more than six hundred thousand times more than all the bright matters. Dark matter is usually a kind of unknown matter, and it has no obvious interaction with atomic nucleus and protons, neutrons, but it does have gravity, and it can't be observed by electromagnetic waves, only by its gravitational effects.
Dark matter plays an important role in stellar systems, because they are distributed in most of the galaxy, and they are the core of stability. It is because of the gravitational attraction of dark matter that the shape of the galaxy and some other phenomena can be found, and these phenomena themselves have a close relationship with dark matter.
Dark matter is also one of the reasons for the formation of the galaxy rotation curve. The rotation curve of the galaxy is actually referring to the curve that all the stars in a certain galaxy forms when they are driven by the gravitational attraction of dark matter. The traditional rotation curve assumes that there is no dark matter in the galaxy, only visible matter, and the curve would be unreliable, so when considering the existence and gravitational effects of dark matter, the rotation curve is more accurate. In this way, scientists can obtain the weight, distribution and influence of dark matter in galaxies, and provide a basis for further explanation of the galaxy's rotational mechanics.
Meanwhile, dark matter, like satellite trabaya, may also form a closed galactic system, that is, the dark matter planet. The dark matter planet has never been observed, and can not be observed by microwaves, they can only be found by interpreting the distribution and experimentally measuring the effect of gravitational force. Moreover, since dark matter does not interact with visible matter, they can also be called black hole planets, which may include small objects like trabaya satellites or larger stars, which may form a healthy, stable galactic system with stars or small asteroids. As dark matter does not interact with visible matter, it is not destroyed by ordinary physical phenomena, but more stable.
Since the discovery of dark matter, scientists have been devoted to explaining what dark matter is actually, how it exerts gravitational effects, and how it affects the shape and rotation curve of galaxies in the universe. According to current researches, dark matter may also form independent galactic systems, so future researches may continue to explore the dark matter planets and their roles in the universe.
