Upgrading the CERN LHC`s CMS experiment detector

Sometimes big questions require big tools. That`s why a global community of scientists designed and built gigantic detectors to monitor the high-energy particle collisions generated by CERN`s Large Hadron Collider in Geneva, Switzerland. From these collisions, scientists can retrace the footsteps of the Big Bang and search for new properties of nature.
