Question: “If your car could travel at the speed of light, would your headlights work?” by Harry Gething from Back To The Battle

What is your first reaction when you read this question? I’m sure a large amount of you who are only familiar with classical mechanics would have thought that they would work, but the light would just travel at the same speed as the car that is moving.  Those of you that are familiar with what we do here would realise for it to warrant a post, it just couldn’t be that simple!  So what is happening?  Well, for this, we have to bring in a new type of physics, relativity.
