In this 2018 photo made available by CERN, Nikolai Bondar works on the LHCb Muon system at the European Organization for Nuclear Research Large Hadron Collider facility outside of Geneva. Preliminary results published in 2021 of experiments from here and the Fermilab facility in the U.S. challenge the way physicists think the universe works, a prospect that has the field of particle physics both baffled and thrilled.
