Inside the Large Hadron Collider

If two protons collide at 99.9999991 percent the speed of light, do they make a sound? What is it like inside the LHC? Symmetry tackles some unconventional questions about the world's highest energy particle accelerator. The LHC accelerates beams of particles, usually protons, around and around a 17-mile ring until they reach 99.9999991 percent the speed of light. If you could watch this happening, what would you see? A: The LHC ring is actually made up of both straight and curved sections. If y...
