日前,针对一些介绍相对论的文章中出现的错误,北京某大报发表《科普文章要有科学性》一文进行批驳。 然而,《科普文章要有科学性》的内容也并不完全科学。该文指出:时下有一些宣传狭义相对论的科普文章,其内容是完全背离狭义相对论理论实质的。比如,一些文章宣扬的所谓‘长命百岁’和‘双胞胎现象’,就是从狭义相对论的时间相对性原理中得出的错误结论。 但实际上,“时钟佯谬”是狭义相对论的主要结论之一,将其应用于假想的宇宙航行,就会得出“孪生子佯谬”的结果。也就是说,如果有两个孪生子,一个乘高速宇宙飞船到远方宇宙空间去旅行,另一个则留在地球上,经过若干年飞船重新返回 A few days ago, in response to some mistakes in the articles introducing the theory of relativity, a major newspaper in Beijing published a speech that “science articles should be scientific” to criticize. However, the content of “science articles should be scientific” is not entirely scientific. The article points out: Nowadays there are some popular science articles that promote special theory of relativity, whose contents completely depart from the essence of the theory of special relativity. For example, the so-called ’longevity’ and ’twin phenomena’ promoted by some articles are the wrong conclusions drawn from the principle of relativity of time in special relativity. In fact, however, the “clock paradox” is one of the main conclusions of the special theory of relativity. When applied to hypothetical cosmic voyages, it will yield the result of “twins paradox.” That is, if there are two twins, one traveling in a space shuttle to a distant cosmic space on the other, and one on Earth, the spacecraft returns after several years
