标题： The twin paradox in the presence of gravity

摘要： 根据运动学（平直空间）直觉的常识告诉我们，一个静止的双胞胎比他旅行的双胞胎兄弟衰老得更快。 然而，如果两个双胞胎处于外部引力场中，并且由于引力导致的空间时间几何的（动力学）畸变足够强，以补偿相对双胞胎运动的运动学效应，那么这种情况可能会被完全颠倒。 显示英文摘要

摘要： Conventional wisdom, based on kinematic (flat-space) intuition, tell us that a static twin is aging faster than his traveling twin brother. However, such a situation could be exactly inverted if the two twins are embedded in an external gravitational field, and if the (dynamical) distortion of the space-time geometry, due to gravity, is strong enough to compensate the kinematic effect of the relative twin motion.
