美国论文代写：暗物质

假设宇宙的形状像一个馅饼，它将被切片在不同种类的美味的部分一致的部分是什么。大部分的馅饼将被视为暗能量，其中包括68%（这是负责加速宇宙膨胀的力量）。只有通过重力和围绕星系相互作用的神秘物质是由27%组成的暗物质。包括行星、恒星、尘埃、气体和人类在内的普通正常物质只有5%。
这是因为暗物质不以任何可能的方式与命名物质的正常物质相互作用。暗物质与规则物质碰撞或吸收了任何一种能量的事例都没有。有了人类可用的仪器，就不可能看到或探测到暗物质。正是因为这样的事实，我们可以看到它的引力的影响，我们可以说，暗物质确实存在。因此，同样的问题出现，如果我们不能够探测到暗物质，也没有人类知道如何能够证明它的确存在（泽利多维奇1989）。很有可能它根本就不存在。当你不知道它究竟是什么，那么你怎么知道暗物质的存在呢？。
但是，在各种研究中说暗物质是存在的。那是在上世纪30年代的暗物质是第一个理论由弗里兹·扎维奇解释星系团的运动。然而，它受到了现代计算对于相同的60年代和70年代薇拉·鲁宾。结果发现，根据她的计算，与世界相比，星系的旋转速度更快。

Assuming the fact that universe is shaped like a pie and it is going to be sliced up in different kinds of tasty parts consistent to what part is what. The majority part of the pie would be regarded to the dark energy which consists of 68% (the force which is responsible for the acceleration in the expansion of the Universe). The mysterious matter which interacts only through gravity and surrounds galaxies is the dark matter which consists of 27%. The regular normal matter which includes planets, stars, dust, gas and humans consist of only 5%.
It is because of the fact that the dark matter doesn’t interact in any possible way with the regular matter that the name is given. There have been no instances where the dark matter has collided with the regular matter or it has absorbed any kind of energy from the same. With any of the instruments available with the mankind it is not possible for one to see or detect the dark matter. It is just because of the fact that we could see the impact of its gravity that we could possibly say that dark matter does exist. Hence, the same question arises that if we can’t detect the dark matter neither do the mankind know anything about it then how is possible to confirm the fact that it does actually exist (Zeldovich 1989). There is very much likelihood that it might not be present at all. When one has no idea as to what it actually is then how do one knows the existence of the dark matter.
But, it has been said in various studies that the dark matter is present. It was in the 1930s that the dark matter was first theorized by Fritz Zwicky to account for the movement of the galaxy clusters. However, it was by Vera Rubin in the 1960s and 1970s that made the modern calculations regarding the same. It was found out that by her calculations that as compared to the world, the galaxies were spinning more quickly.
