Light isn't some speed limit. There isn't a space cop telling you that you can't go faster. It's that, no matter how fast you travel, light will always seem to travel at the same speed, relative to you. It's space and time that bend around you as you approach the speed of light. So, if you go .9999c, you can reach places in a matter of weeks that are many light years away. But to those watching you back home, it will still appear to take you that many years to get there.
