Hi all, in my naive and simplistic world particle accelerators accelerate particles in opposite directions at very fast speeds until at just the right speed and time they collide and some really really neat stuff happens.

Here's where I need some educating; these particles are moving at close to the speed of light (?)... this means that when they collide they have a closing speed greater than the speed of light(?)... if the maxim that for every action there is an equal and opposite reaction applies in this case does that mean that what comes out of this collision is travelling at a speed greater than the speed of light?
