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

The twin paradox in the presence of gravity
