Startup has been eagerly awaited by 9,000 physicists around the world . It 's the largest particle accelerator in the world and costs about $ 9 billion . Since this is exploratory science , the collider may uncover surprises that contradict prevailing theories , but which are just as interesting , said Joseph Lykken , theoretical physicist at the Fermi National Accelerator Laboratory . The goal is to create a new type of energy called " dark matter, " which would be invisible but could explain why there are so many galaxies out there that we can't see with our eyes (
