1919年，在柯尼斯堡大学任教的数学家卡鲁扎给爱因斯坦寄去一篇论文，提出在四维时空基础上引入第五维度。将爱因斯坦广义相对论方程推广到五维后，电磁力自然从多出来的几何分量中浮现——引力与电磁力被统一在同一个五维框架里。爱因斯坦最初很满意，支持发表了论文，但最终放弃了这条路：第五维无法被实验验证，且只能统一两种力。1926年，瑞典物理学家克莱因回答了"为什么看不到第五维"——它蜷缩成普朗克长度（10⁻³⁵米）的微小圆圈，并用量子力学加固了理论。但卡鲁扎-克莱因理论最终失败：5维只能统一引力和电磁力，... more
1918年，数学家韦尔在苏黎世发表《引力与电》，试图用"尺度变化"几何统一引力和电磁力。他发现：如果矢量大小随平行移动而变化，这个变化恰好对应电磁势——统一是修几何的偶然副产品。但爱因斯坦在论文后附评论反驳：按韦尔理论，尺子长度和时钟快慢取决于移动路径，这违反物理经验。韦尔的规范理论在1918年就死了。11年后，量子力学拯救了它的内核——薛定谔和伦敦发现，把"尺度变化"改为"波函数相位变化"，规范不变性恰好对应电荷守恒。韦尔选错了工具，但工具活了下来——1954年杨振宁和米尔斯将规范理论推广，成... more
广义相对论和量子力学在黑洞处撞上了——两个都对，但不可能都对。黑洞是宇宙中唯一一个"大尺度+强引力+小尺度"同时出现的地方，统一不是哲学偏好，是物理必需。80年来，大致有两种策略：把引力量子化（弦论、圈量子引力），或把引力消解（ER=EPR）。两种都没有成功。但80年的失败不是白费——每一次失败都排除了一个维度的问题。本周追踪80年来的失败：韦尔、卡鲁扎、爱因斯坦，每个人走了不同的死胡同，每次失败都不同。本期你会听到：

信息悖论50年未解——但它是关于什么的问题？本期深度付费版从三个层次回答：第一幕把信息守恒放到守恒律演变史的大框架里——能量守恒被爱因斯坦修正（质能等价），电荷守恒被狄拉克的磁单极子假说挑战，信息守恒被黑洞逼到墙角。每一次守恒律被挑战，都指向一个更深的层次。第二幕拆开信息悖论的数学骨架——纯态与混合态、密度矩阵纯度、纠缠单配性、AMPS不可能三角的五步逻辑链。好的悖论不是错误，是旧框架的边界暴露，也是新框架的入口。第三幕面对两千年哲学争论：物理定律是"发现"的还是"发明"的？柏拉图说发现，亚里士... more
