Answer to Question #8028 in Mechanics | Relativity for Boss

Question

According to Einstine's Theory of Relativity, time moves slower when we're closer to the ground (gravitational field). Here's the question. If one of an identical twin were to be raised on space station where time moves quicker, then after 10 years of Earth time - would they look different? Like will one of them look literally older than the other? thanks
