When he returns, he finds his twin old and gray, even though he is still young and thinks that only a few days have passed. The faster the starship is, the greater the discrepancy in the time the two twins would experience. So if somebody took a one day round trip in a ship travelling at 99.99999999963% of the speed of light, then indeed a thousand years would have passed on the earth when they returned … ."
