![万物的终结 - [美]凯蒂·麦克](https://static.book345.com/covers/s/9787559659170.jpg)
书籍介绍
大多数人读宇宙学，是想获得确定的答案；这本书却诚实地把'不确定'摊开给你看。它用大坍缩、热寂、大撕裂、真空衰变、大反弹五种结局，带读者走到已知物理定律的尽头——而那里恰恰是广义相对论与量子力学彻底闹翻、普朗克时间之后无从外推的地方。读者反复提到的，不是某个具体结论，而是作者一边写一边给自己批注吐槽的劲头：知识在这里不是终点，'doing'和'process'才是。它适合那些愿意承认'看不懂'、却仍被宇宙末日图景勾住的人；读完你不会更恐惧，反而像有人轻声说'就像宇宙把自己收拾干净了'——短暂的东西，也值得被认真地了解。

精彩摘录
- "Only, a singularity doesn't have to be a point - it could just be an infinitely dense state of an infinitely large universe"
- "(general relativity and quantum mechanics) ... they don't work well together, at all..."
- "Without a full theory of quantum gravity (something that reconciles particle physics with gravity), there's a limit to how far back we can extrapolate the universe in a way that makes sense. ... what moment that confusion sets in, we call this the Planck time, and it encompasses the time from zero t"
- "After the Planck time comes the GUT era (... 10^-35 seconds) ... at high enough energies, the forces start to merge and combine, rearranging the structure of particle interactions and the laws of physics. ... just looks complicated because of our weird low-energy perspective"
- "The theory of inflation came to solve... the weird uniformity of the cosmic microwave background, and its tiny imperfections. ... The hypothesis is that inflation was driven by a kind of energy field subject to quantum fluctuations... which would normally only be ephemeral blips on a microscopic sca"
- "the quark era ... while strong force had broken away from the GUT, electroweak force stayed intact... finding a single quark in isolation has so far proved impossible... quarks and gluons bounced around freely in a hot roiling mix called a quark-gluon plasma - kind of analogous to the inside of a fi"
- "At around a tenth of a millisecond, the first protons and neutrons formed, followed shortly by electrons... Somewhere around the two-minute mark, the first bounded atomic nucleus formed... This process, called BigBang Nucleosynthesis, went on for about half an hour..."
- "... the surface of last scattering ... at about 380,000 years, light went from being trapped in plasma to traveling long distances across the cosmos. ... it is the beginning of cosmic Dark age ... sometime around the hundred-million-year mark, one of the clumps becomes so dense it is able to ignite "

作者文风还是挺俏皮的，但就是爱拿注释当吐槽用。书中多次提到的弦理论和圈量子引力论，之前读过这两个不同研究方向的两个代表人物加来道雄和卡洛·罗韦利的书，对一些概念有一些肤浅的认识，目前读过的所有物理学方面的科普书籍，物理学家们都是白天想夜里哭做梦都想大统一。
宇宙各种可能的结局，但宇宙学家也不知道哪种才是答案。
可观测宇宙450亿ly球 哈勃半径140（以c远离我们 随时间变化now⬆️ 物质可越过 因最初膨胀速度减小过 跑步机比喻很绝妙P82）90亿年加速膨胀至今 若光在加速膨胀之前未进入半径则再也无法观测 但能观测到则表观半价更大 因为当年uni很小 近大远小 “能量梯度是生命的基础 热没有用 热即死亡” 庞加莱回归玻尔兹曼大脑部分在尼采的加持下跟恐怖游轮差不多了 戴森越来越慢的电脑和幽闭恐惧so cute
封底有兰道尔•门罗的推荐语，说这本书有卡尔•萨根的风格。我的偶像A拉了偶像B来背书，我信了。但是，它真的好难读。只有真空衰变那章写得很有画面感。
看得很吃力。
累了，毁灭吧。
宇宙现在就给我毁灭吧！
妈的好有趣 4.5 但鼓励了

做为宇宙的匆匆过客, 当下的此刻才是不变的永恒 - 我很高兴来到这多姿多彩的世界看到犹如万花筒般多彩绚丽的世间万物, 即便只有短暂一瞬。
恐怖的就是发现宇宙毁灭亦或不毁灭都解答不了存在的问题
