I need some discussion about a question I got in my Year 12 Physics book. The answers in the book say no, because it is greater than the speed of light. That, I don't have a problem with; if it takes infinite force to accelerate a particle to the speed of light, it's not possible to get faster than the speed of light, as you would need more than infinite force to get that fast. But neither of the objects are actually going at the speed of light; one just appears to be going that fast from the other. If you point two torches at each other and turn them on, the relative speed of light coming from one torch relative to the other would be twice the speed of light, which is apparently not possible. What do you think?
