My question is if I get into an ultra-fast rocket and go into the direction that counter the movement of earth, solar system, Milky way, Local Group, Supercluster, and etc, would I aged faster or slower than if I stay on earth?
Time passes different for different observers, depending on the observers' motion. The common example is the two hypothetical twins: One of them stays at home, on Earth. The other journeys into space in an ultra-fast rocket, nearly as fast as the speed of light, before returning home.
Einsteins special theory of relativity states that time passes differently for different observers. Basically the faster you travel the slower you aged. So I assumed this means to aged the fastest, you don't move.
We also know Earth is moving around the sun. The solar system is moving upward...
