Hi lewichan,
Boy this is a difficult question! I find physics really difficult to get my head round so I have been asking around to try and find you an answer and I have found the answers difficult to understand myself.
But what I have found is that it would be impossible for you to travel at the speed of light in a car, as you approached the speed of light the energy required to make you go faster would get greater and greater and it is just impossible. Apparently according to Einstein’s theory of special relativity you cannot get an answer to this question (it confuses me but the answer was zero :S)
I can answer what would happen if you were travelling NEAR the speed of light…..apparently then you would observe no unusual effects, your lights would turn on as expected however what you see of the world around you would be strange.
This is where it starts to get really odd….ok…so apparently due to the speed you are travelling the light gets changed to ultraviolet! So you would need a special camera to see anything then it would all be rotated…weird right!!!!!!
So that is a very complicated answer and I am not even sure I understand but I hope you like it!
Pam 🙂
Well I do not know. So far its impossible to go that fast, and in fact it may be theoretically impossible to be as fast as the speed of light.. But theory is boring, so let’s assume we can!
Headlights make light, which will travel at a certain speed. The speed is constant, and so if your car is going at a certain speed, than the speed of the light from your car is the same anyway… So maybe nothing would happen !
However, if you go at the speed of light, there’s a might be an excellent chance of some cheeky time traveling, as moving increasingly fast is looking like the most likely way of achieving ‘time travel’, at least in some sense.
I have a bad feeling Einstein would be very upset by all this though….. Lol
Oh well done Pam! Lewichan, I hope you are happy with yourself! This question had me up half the night. Eventually I resorted to google which has given much the same answer as Pam. Here is the webpage I found on it: http://www.desy.de/user/projects/Physics/Relativity/SpeedOfLight/headlights.html This is the most physics I ever want to do again!! Give me a biological problem any day!

Yeap that is the web page I used! 🙂
