Nobel laureate François Englert, a Belgian physicist renowned for his work theorizing the Higgs boson, has died at the age of 93. Englert was awarded the 2013 Nobel Prize in Physics jointly with Peter Higgs for their independent development of the theory predicting the existence of the fundamental particle. The Higgs boson, often called the “God particle,” explains how other particles acquire mass. His work, conducted decades earlier, was experimentally confirmed at the Large Hadron Collider in 2012, a landmark achievement in particle physics. Englert’s passing marks the end of an era for theoretical physics and leaves a significant void in the scientific community. He is survived by a substantial scientific legacy that continues to shape our understanding of the universe.
