Query: Hope for our future

This is an odd story. It develops into a quest for the meaning of life. I enjoyed it's start: China and Japan have taken the lead in space exploration because the United States has not shown the desire to put money into such ventures. Then there is the time traveling aspect: going through portals to other systems takes the time it takes for light to travel, so rather then instantenous appearance, it is five or six years to get there and the same amount to get back. Rather simple, but no one has mentioned it before.The ending is a treat, a bit unsatisfying because you want to see happiness and success, and it is there in a sense, it is not what you expect.
