If you manage to reach the speed of light, and you travel ten light years, in your perspective, you will travel ten years, whereas outside of the area traveling, time passes by ten thousand.
Actually, at light speed travel would be instantaneous. Doesn't matter if you're travelling a distance of 1km, or a trillion km, it's instant transmission. Space as well as time contracts to zero, so you're just here one moment, and then you're there.
The most mindducky part to me is that light speed isn't actually that fast. It's meandering at ~300 000km/s for people on earth, but for the light speed traveller, it's instant. It would make more sense intuitively if light was just universally instantaneous.
I think it's incredibly cool, though, that you could actually travel to distant parts of the universe in your own lifetime, if only you could move close to the speed of light. Of course, trillions of years could pass on earth in the meanwhile.
