A masterpiece of civil engineering The excavation of the Large Electron–Positron tunnel was Europe’s largest civil-engineering project prior to the Channel Tunnel. Three tunnel-boring machines started excavating the tunnel in February 1985 and the ring was completed three years later. The first beam circulated in the LEP on 14 July 1989 and, during its 11 years of research, the LEP experiments provided a detailed study of the electroweak interaction. To this day, the #LEP remains the largest ele

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.
