The task is to determine how much time will pass for the explorer during a journey to a star 10,000 light-years away. By applying the principles of relativity, we can calculate that the explorer, starting at 30 years old, will experience only 70 years during the trip, despite the journey taking much longer in the stationary frame of reference."}
