The scenario involves a spaceship traveling to a star 10 light-years away at 0.8c, and the objective is to calculate the time that passes on Earth during this journey. By applying the formula for time dilation and the relationship between distance, speed, and time, we find that 12.5 years elapse on Earth during the trip."}
