为什么宇宙膨胀不断？
1、宇宙膨胀是由爱因斯坦的广义相对论预言的，该理论指出宇宙中的物质和能量会推动时空的膨胀。
2、大爆炸理论认为，宇宙起源于一个极度炽热和密集的状态，随着时间推移，宇宙不断膨胀，温度和密度逐渐降低。
3、观测到的遥远星系的光谱红移现象表明，这些星系正在远离我们，这进一步支持了宇宙膨胀的观点。
4、宇宙膨胀的速度并非恒定不变，而是受到暗能量的影响，暗能量是一种神秘的力，占宇宙总能量的约68%，它推动宇宙加速膨胀。
5、宇宙的膨胀并非简单的物理运动，而是时空本身的膨胀，这意味着空间本身在扩展，导致星系之间的距离不断增加。
总之，宇宙膨胀不断是由于时空本身的扩展、暗能量的推动以及大爆炸的初始条件共同作用的结果，这一现象揭示了宇宙的动态演化过程。
