那么暗物质和暗能量在地球上从一开始就是一个非常令人困惑的问题。所以今天我们将尝试了解暗物质和能量. 暗物质和暗能量简单地解释了我们在宇宙中发现了一些非凡的东西. 我们在日常生活中所经历的普通物质和能量所组成的比 5% 暗物质构成的东西 27% 已知宇宙和暗能量构成了另一个 68%. 我们对暗物质和暗能量知之甚少，因此点这个词被用来描述两者.
暗物质
- Nature Dark matter is believed to be a kind of substance that neither emits nor reflects electromagnetic radiation, making it invisible and only detectable through its gravitational effects.
- Effects The motion of visible matter (stars, galaxies, gas clouds) is influenced by dark matter due to their gravity. It is suspected to be responsible for the phenomena dubbed gravitational lensing where light from far away galaxies gets bent due to massive intervening bodies.
- Distribution Dark matter is presumed to exist everywhere in the universe, forming halos around individual galaxies as well as clusters of galaxies.
- Composition Although the exact composition remains unknown, dark matter might consist of non-baryonic particles such as WIMPs (Weakly Interacting Massive Particles) or axions i.e. other than protons and neutrons.
Dark Energy
- Nature Dark energy is an enigmatic form of energy that fills all space and causes the expansion of the universe at an accelerating rate.
- Effect Different from dark matter which attracts matter gravitationally, dark energy acts as a repulsive force and leads to an accelerated expansion of the universe over time. This acceleration counteracts the gravitational pull between galaxies and results in an overall expansion of the universe.
- Distribution It appears that dark energy is evenly spaced throughout space and affects the large-scale structure of the cosmos.
- Origin What exactly is dark energy and where does it come from are not yet known. One hypothesis is that this could be vacuum energy or a cosmological constant associated with empty space itself.
什么是暗物质 ?
我将简要介绍迄今为止我们所知道的暗物质. 暗物质是一种物质形式 不与光相互作用 所以它对我们来说是不可见的，因为计算表明，如果没有它 引力星系 宇宙中其他无法形成暗物质的大型结构也需要解释星系的运动. 它解释了为什么星系外围的恒星和气体云旋转得如此之快.
爱因斯坦 描述了一个时空连续体，因为宇宙时空的结构包含了三个
上下空间维度,左右后退. 时间的第四维度爱因斯坦认为时空是可延展的质量和能量，可以扭曲时空，从而产生引力现象. 暗物质确实有质量，因此会产生引力. 在它有大块的地方，暗物质扭曲了来自它后面星系的光. 这种失真效应称为 引力透镜. 几十年来，我们一直在寻找暗物质以及宇宙学家的普遍共识.
什么是暗能量 ?
它可能由一种奇异的亚原子粒子组成，我们尚未在其中探测到暗能量 1929 天文学家 埃德温 哈勃 发现膨胀的宇宙 一个物体离地球越远，它看起来越红，因为它的光的波长向我们射来. 它被拉伸的电磁光谱是从无线电波到存在的整个光范围 伽玛 射线可见光是人眼可以感知的伊莱克特拉光谱部分内的电磁辐射. 更长的波长对应于向电磁光谱的红色端移动.
哈勃 注意到星系越远红移越多, 经过对不同红移的详细分析. 他得出的结论是，直到 90 年代后期，星系都在飞离，宇宙的规模还在不断扩大. 他签署了他的想法，即由于物质引力的影响，宇宙的这种膨胀会减慢甚至收缩. 然而在 1998 观测证据证实宇宙的膨胀实际上正在加速, 导致这种加速的原因被称为暗能量，它也没什么, 知道这种暗能量. 但它可以被认为是空间的一种属性. 一个空间正在扩大，并且出现更多空间来填充额外的空间.
这 dark energy intrinsic to space is pushing galaxies further apart and that concludes my inquiry on dark matter and dark energy. 这显然是对这两个主题的高级概述，本文旨在作为进一步学习的跳板，我希望你喜欢这篇文章.
pair of identical but connected concepts in cosmology that are highly important for the shaping and dynamics of the universe. This is followed by a short explanation on what differentiates them.
In conclusion, though both provide insights into cosmic dynamics, there exist differences between dark matter and dark energy in terms of their properties, impacts and roles in cosmology. Gravitational effects from Dark Matter help keep galaxies together and induce motion while on the other hand matters about expansion through gravitational pull requires Dark Energy.
