孪生悖论:加速的作用

The twin paradox: the role of acceleration

J. Gamboa, F. Mendez, M. B. Paranjape, Benoit Sirois

摘要:

双胞胎悖论,从两个双胞胎可能因为他们的相对运动而年龄不同的想法中唤起,自从1906年首次描述以来,狭义相对论被发明的第二年,一直被研究和解释。可以这样问:“还有什么要说的吗?“很明显,加速度起着一定的作用,但这一作用在很大程度上被忽视了,因为在一个优选的参考系中,计算双胞胎的相对年龄差时不需要加速度。事实上,如果试图从经历加速的双胞胎的观点来计算年龄差异,那么加速的作用是至关重要的,不能被忽视。在解决孪生子悖论的过程中,加速度的作用被贬低到了一种程度,以至于它被当作一种转移注意力的东西。这是一个错误,表明对孪生子悖论的明显误解。

英文摘要:

The twin paradox, which evokes from the the idea that two twins may age differently because of their relative motion, has been studied and explained ever since it was first described in 1906, the year after special relativity was invented. The question can be asked: "Is there anything more to say?" It seems evident that acceleration has a role to play, however this role has largely been brushed aside since it is not required in calculating, in a preferred reference frame, the relative age difference of the twins. Indeed, if one tries to calculate the age difference from the point of the view of the twin that undergoes the acceleration, then the role of the acceleration is crucial and cannot be dismissed. In the resolution of the twin paradox, the role of the acceleration has been denigrated to the extent that it has been treated as a red-herring. This is a mistake and shows a clear misunderstanding of the twin paradox.
