爱因斯坦的相对论指出：主体选择不同的参照系对同一物理事件和物理过程进行时空度量，所得结果可能不一样。在认识论上来说是由
A．真象和假象的区别所造成的
B．现象和本质的矛盾所造成的
C．主体和客体的关系的变化所造成的
D．由于主观认识的错觉所造成的
参考答案：C
解析：爱因斯坦的论断是符合事实的科学论断。比如，你坐在火车上不动，在火车这一特定参照系而言，你处于相对静止状态，但从火车之外来观察，你和火车一样在飞速地运动。这就是艾氏讲的主体选择不同的参照系对同一物理事件进行时空度量，其度量结果不同。从哲学上说明，主客体的关系的变化(选择和处于不同的参照系中)造成不同的认识结果。因此，正确选项是C。在这里造成不同的认识结果，同真象和假象的区别无关，也同现象和本质的矛盾无关，也不是什么错觉。因此，备选项A、B、D错误。
