In this video, we explore CERN’s most mind-bending experiment yet—an artificial recreation of the Big Bang using the world’s largest particle collider. Deep beneath the Earth’s surface, the Large Hadron Collider accelerates heavy lead ions to near light-speed and smashes them together, generating a quark–gluon plasma: the same exotic state of matter that existed just microseconds after the universe was born. This plasma is hotter than the core of any star and denser than anything we’ve ever crea

Grab your hard hat, we're off to see the ATLAS Experiment at CERN! Enjoy a 40 minutes guided 360° tour of the world's largest particle-physics experiment from the comfort of your own home. This full-length tour recreates a public tour of the ATLAS Experiment, while also taking you to parts of the cavern only accessible to engineers. It is a unique opportunity to explore the experiment with physicist Dr. Sascha Mehlhase, who explains the physics and engineering behind this mammoth detector. Watch
