引力波证实霍金黑洞面积定理

激光干涉引力波天文台（LIGO）探测到两个黑洞之间异常强烈的碰撞，这使得物理学家能够验证斯蒂芬·霍金在1971 年提出的黑洞面积定理。该定理指出，当两个黑洞合并时产生的黑洞视界，即连光都无法逃脱黑洞控制的边界，其面积不能小于两个原始黑洞的面积之和。该定理与热力学第二定律相呼应。热力学第二定律指出，熵或物体内部的无序状态永远不会减少。黑洞合并扭曲了宇宙的结构，产生了被称为引力波的微小时空波动，能被引力波探测器观测到。最近的这次碰撞被命名为 GW250114，与 2015 年首次观测到的产生引力波的碰撞几乎完全相同。这两次黑洞的质量都在太阳质量的 30-40 倍之间，发生在 13 亿光年之外。这一次升级后的 LIGO 探测器灵敏度是 2015 年的 3 倍，因此它们能够以前所未有的细节捕获碰撞产生的波。这使得研究人员能够通过计算证实黑洞合并后视界面积确实变大，从而验证了霍金的定理。

古墓丽影系列的法语配音演员 Françoise Cadol 向《古墓丽影 4-6 重制版(Tomb Raider 4-6 Remastered)》开发商 Aspyr 发出停止通知函（cease and desist），指控 Aspyr 使用 AI 拷贝其声音但没有通知她或告诉游戏玩家。她形容此举是一种背叛，一种彻底的不尊重。除了法语，巴西和西班牙等地区的玩家也认为其语种的配音是由 AI 生成的，AI 合成了原配音演员的声音。巴西配音演员 Lene Bastos 收到了 Aspyr 的一封回信，它的调查显示外部开发合作伙伴在其不知情下使用生成式 AI 编辑原始声音，它表示自己没有授权这么做，对未能在审核中注意到该问题表示歉意。
