A space traveler moving at the speed of 0.70c with respect to the earth makes a trip to a distant star that is stationary relative to earth. He measures the length of this trip to be 6.5 light - years. What would be the length of this same trip (in light- years) as measured by a traveler moving at speed of 0.90c with respect to the earth?
