附加题:车-车库问题 Carman 买了一辆世界上最长的轿车,其固有长度为 L c =30.5m 。在图(a)中,它停在固有长度 L g =6.00m 的车库 前面。车库有一个前门(开着)和一个后门(关着)。车 明显地比车库长。但是, Garageman ,车库的所有者,他 知道些关于相对论长度缩短的知识,乃和 Carman 打赌说 车能够停在前后门都关闭的车库里。 Carman ,在到狭义 相对论之前就中断了物理课,说这种事,甚至在原则上都 是不可能的。

g x 0 g L a c L c x 0 为了分析 Garageman 的方案,在车附上一个 x c 轴, x c =0 后保险杆上,并对车库附上一个 x g 轴, x g =0 在(现在开着 的)前门处。然后, Carman 就要驱动汽车以 0.9980c (当 然在技术上和经济上这是不可能的)直接向车库前门开去。 Carman 静止在 x c 参考系中, Garageman 静止在 x g 参考系 中。
