to simplify thus:
1. space and time are relative, that's why einstein came up with his neat theory of relativity, which was further simplified by jack warner of warner bros. with his own theory of relativity---he doesn't hire relatives.
2. there are no unusual effects of traveling with the speed of light if you just stay within your car
3. if you look out the window of your car with its headlights on while traveling at the speed of light, the light of your headlights will come back to haunt you.
4. it is always unsafe to travel at the speed of light. in the first place, why the hurry?
5. but if you must travel at the speed of light despite the odds, then travel with a loyal friend.
