Why might future space travelers return to find their children older than they were? Well the faster an object travels, the slower time passes for it. If future astronauts could travel to distant stars at speeds much higher than are yet possible, very odd things would happen. If they were away ten years, they might return to find that forty years had passed on Earth. An astronaut who was 25 when he left, saying goodbye to her daughter of three, would return aged 35 to find her daughter was 43. See am odd things will happened.
