老七啊，你要這麼想，你們有矛盾了，要麼他錯，要麼你錯。要麼，你們倆都錯了。。很簡單
從科學角度來說，有時候兩都對了，都說的事實，而其陳述也有可能是矛盾的。比如霍金舉過這樣的例子：
To picture this, suppose someone on a train bounces a Ping-Pong ball straight up and down, hitting the table twice on the same spot one second apart. To that person, the locations of the first and second bounces will have a spatial separation of zero. To someone standing beside the track, the two bounces would seem to take place about forty meters apart, because the train would have traveled that distance down the track between the bounces. According to Newton, the two observers have an equal right to consider themselves at rest, so both views are equally acceptable.
Picture again the speeding train. In Chapter 4, we saw that although someone on the train bouncing a Ping-Pong ball up and down may say that the ball traveled only a few inches, someone standing on the platform would perceive the ball as traveling about forty meters. Similarly, if the observer on the train shone a flashlight, the two observers would disagree on the distance the light traveled. Since speed is distance divided by time, if they disagree on the distance the light has traveled, the only way for them to agree on the speed of light is for them to also disagree about the time the trip has taken. In other words, the theory of relativity requires us to put an end to the idea of absolute time! Instead, each observer must have his own measure of time, as recorded by a clock carried with him, and identical clocks carried by different observers need not agree.
同本樓無關，主要是想說：互相矛盾的事不見得就一定是有錯的，有一個立場問題在裡面。有時候甚至是同一立場，也有矛盾的事實存在，比如我們的宏觀物理世界和微觀物理世界就是矛盾的，宏觀上一切有規則有序，微觀上所有的事物全部是概率和無序，但我們的世界在宏觀和微觀上是同時存在的。 |
