Ok, as you approach the speed of light, everything starts lagging, the closer you are to the speed of light the slower time goes for you, or the faster it goes for the rest of the world. If you flew away from the earth at lightspeed, everyone would be dead within a few seconds or days. This is because the next time light would reach you, it would be years later. Now if you move back to earth at the same speed, light will take less time to reach you until it reaches you instantly. The lag is proportional to how close you are to the speed of light, so the paradox is what would it look/be like once you hit or go beyond the speed of light. People would have to look for something else as reference to space-time otherwise you would literally be frozen in time. This will never happen though since the energy needed to reach the speed of light is exponential and it would take more energy than in the whole universe to reach it. Which is why you can't move matter or energy at the speed of light. Or something like that.
