Does the LHC collide protons at twice the speed of light?

Now, if you have objects that move almost at the speed of light, you have to use Special Relativity to describe what they do. For this, in special relativity, you have to add u and v by the following equation:

You see right away that the result of this addition law is always smaller than 1 if both velocities were smaller than 1. Therefore, if light is made of massless particles, then the speed of light is identical to the limiting velocity.
