How CERN Built the Impossible 27KM Machine to Recreate the Big Bang - Then It Exploded 9 Days Later

How CERN Built the Impossible 27KM Machine to Recreate the Big Bang - Then It Exploded 9 Days Later Beneath the border between France and Switzerland sits a 27-kilometer ring of superconducting magnets, cooled colder than outer space, built to recreate conditions from less than a trillionth of a second after the Big Bang. Nine days after switching on for the first time in 2008, a single faulty electrical connection destroyed part of the machine in a violent helium explosion, forcing a 14-month rebuild. This is the story of the Large Hadron Collider: the most complicated machine ever built, the disaster that nearly ended it before it started, and the discovery — the Higgs boson — that made all of it worth it. 📌 Disclaimer This video is created for educational and informational purposes only.
