Think about traveling at the speed of light with 1 clock behind you and 1 beside you in your light speed machine.

Standing still, both clocks point directly at 12:00...

For simplicity sake.. say you instantly start moving at the speed of light. You look behind you and the light comming from the hands of the clock is moving at the same speed as you, so what you see is the clock still pointing at 12:00. Because you are going at the same speed the light never has a chance to catch you. Think of it like running the same speed as bullet, as long as you are going the same speed as it is, you are not gonna get shot, it stays a constant distance behind you. What do you think is gonna happen with that bullet when you stop? Say You travel for 10 min at light speed, according to the clock on your machine.. then come to a full stop.

The light from the clock behind you starts catching up to you and the hand would appear to start moving, same as the bullet would. The clock would appear to be 10 min behind the one in your ship, because the light that left 10 min ago is only starting to pass you now..

You start moving at the speed of light again. The clock behind you stops again at 12:01 your inside clock says 12:11. Now you turn on Light after burners and are suddenly going Faster then the speed of light. Now you are catching upto and passing the light the left the clock behind you.. so it starts to move backwards... and after another min of travel your ship clock says 12:12 and the clock behind you says 12:00 again.. you keep going and the clock behind you starts showing 11:59....58....57 and you clock reads 13..14...15...

Techincally you are going BACK in time. All the while you are moving the pace of time back at the other clock never changed..

So as you are moving away from the clock behind you, the faster you go, the slower time moves on that clock untill you hit the speed of light at which time STOPS. So while time stops for you the people back at the first clock have been continuing to watch the clock at the normal time speed. You appear to have been gone MUCH longer then them because time has slowed to a crawl or stopped for you. So your 15 min of travel to you has taken 10's of years to the people behind you.
