Clock paradox

原声例句

Clocks paradox attacked Dingle's disproof of Einstein centres around the so-called clock paradox, in which a fast-moving clock loses time.

时钟悖论攻击了丁格尔对爱因斯坦的反驳，其核心是所谓的时钟悖论，即快速移动的时钟会失去时间。

This increase in life is out proportion to the increase in speed, so the physicists say the clock paradox is supported by experimental evidence.

寿命的增加与速度的增加不成比例，因此物理学家表示时钟悖论得到了实验证据的支持。

Diagrama espacio-tiempo que muestra al gemelo alejarse (primer tramo línea negra) y regresar a la Tierra. En este diagrama la posición de la Tierra en cada instante se mueve a lo largo del eje vertical. La distancia entre la última línea azul y la primera roja representa no envejecido el tiempo ganado por el viajero.
Un posible esquema del viaje de ida y vuelta del gemelo viajero, en cinco fases: alejamiento acelerado, alejamiento a velocidad constante, frenado y cambio de sentido, acercamiento a velocidad constante, frenado hasta reencontrarse con el gemelo terrestre.
Minkowski diagram of the twin paradox. There is a difference between the trajectories of the two twins: the trajectory of the ship is equally divided between two different inertial frames, while the Earth-based twin stays in the same inertial frame.

双生子佯谬是一个有关狭义相对论的思想实验。有一对双生兄弟，一个登上一宇宙飞船作长程太空旅行，而另一个则留在地球。结果当旅行者回到地球后，他发现自己比留在地球的兄弟更年轻。

这个结果似乎与狭义相对论矛盾：双生兄弟中的每一个人都认为对方相对于自己运动，因此由于时间膨胀的作用，每一个人都认为对方应该比自己年轻。狭义相对论指出所有观测者都有同等意义，没有任何一个参考系（frame of reference）是会获得优待的。因此旅行者会预期回到地球后会看见比他更年轻的双生兄弟，但这就与他兄弟的想法恰好相反。

In physics, the twin paradox is a thought experiment in special relativity involving identical twins, one of whom makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more. This result appears puzzling because each twin sees the other twin as moving, and so, according to an incorrect naive application of time dilation and the principle of relativity, each should paradoxically find the other to have aged more slowly. However, this scenario can be resolved within the standard framework of special relativity: the travelling twin's trajectory involves two different inertial frames, one for the outbound journey and one for the inbound journey, and so there is no symmetry between the spacetime paths of the two twins. Therefore, the twin paradox is not a paradox in the sense of a logical contradiction.
