hello ppl Imagine that you are on a spaceship flying very close to the speed of light and we know that time slows down significantly at this speed relative to that on earth. now say every day for the persons on the spaceship is a whole year for a person on earth. So for a person on the spaceship the distance travelled is the 'speed(Km/Hr)' of the craft multiplied by the '24' Hr in a day.. while for a person on earth the distance covered by the space ship would be the speed(Km/hr) of the spaceship multiplied by 24Hr multiplied by 365 days .(of course in an year on earth but it's still a day on the space ship.) So it gives two completely different answers for the distance travelled. How is that?? may be it's a dumb question but i am unable to figure it out!!
