Lightspeed!
You may have seen this happen in Sci-Fi movies a lot.
When a space ship goes light speed, you begin to see all the stars move to your back and they appear to look like streaks. In a sense, this is similar to what you are used to seeing, say at night when cars would zoom by and leave a light trail.
Two students of special relativity are having an argument over this:
Dave: "I think it looks really cool when the stars form streaks in all those space movies when the starship goes light speed! You move so fast that the universe look so slow and the light from the stars get all stretched out"
Jane: "You know in actually, I think when you go light speed, the stars behind you should move to the front."
Who is right?

Best explanation i could give is Einstein's first postulate in special relativity: "Lightspeed is right the same in any inertial reference frame", then, even when you go lightspeed, you see light going lightspeed
