In various documentaries they bring up the argument that we wont be able to visit other stars because even if we would travel with the speed of light, it would take xxx years, since the next habitable planet is xxx lightyears away. BUT: What about time dilation? If an object approaches light speed, time from its point of reference moves very slow. At lightspeed time stands still. My conclusion: If we can travel fast enough (but still SLOWER than lightspeed), we should be able to travel for example 1000 lightyears in just 10 minutes (in the meantime on earth, more than 1000 years pass). Where do i go wrong here? Or are these documentaries just wrong?
