3 ms·Time dilation should be negligible at low speeds; the effect is gamma = (1-(v/c))^(-.5)by pizza 10y agoTime dilation should be negligible at low speeds; the effect is gamma = (1-(v/c))^(-.5)ajnin 10y agoYou have a small error, gamma is actually (1-v²/c²)^(-.5) , which translates to about 10ms for his 1-year stay in the ISS.pizza 10y agoOops, I knew that that looked too simple somehow.. thanks
