The LHC tunnel and that of its successor, the High-Luminosity LHC, are now connected. This week, the civil engineering companies made the junction between the underground facilities at Points 1 and 5 of the accelerator. Lucio Rossi, Leader of the HL-LHC project, Frédérick Bordry, Director for Accelerators and Technology, Fabiola Gianotti, CERN Director-General, and Oliver Brüning, Deputy Leader of the HL-LHC project, met this morning in the LHC tunnel to celebrate the breakthrough.

Scientists Announce a Puzzling Discovery At The Large Hadron Collider! | The Secrets Of The Universe

Scientists at CERN's Large Hadron Collider have succeeded in transforming lead into gold, fulfilling an age-old alchemical dream using modern physics. The ALICE team achieved this by colliding lead nuclei at nearly the speed of light. The resulting electromagnetic fields caused three protons to be ejected from the lead atoms during close encounters, thus creating gold. Between 2015 and 2018, 86 billion gold atoms—about 29 picograms—were produced in this way, at a rate of 89,000 atoms per second.
