1问题背景车缝佯谬是一个有趣的物理问题,理解车缝佯谬可以很大程度地理解狭义相对论的时空观.该佯谬(本质是长度佯谬)的内容是这样的:一辆列车在地面上匀速行驶,驾驶员突然发现正前方有一道宽度比列车长度稍长的裂缝,驾驶员认为,如果列车加速到某一速度,裂缝由于具有相对车子而来 1 Problem Background Sewing paradox is an interesting physical problem, and the understanding of sewn paradox can greatly understand the space-time view of special relativity. The paradox of this paradox (the essence is length paradox) is this: a train Driving at a constant speed on the ground, the driver suddenly found a crack just a little longer in width than the length of the train in front of the driver. The driver believed that if the train accelerated to a certain speed, the crack was due to having a relative car
