A New York Times article on Jan. 24, 2019 by Dr. Sabine Hossenfelder summarizes the state of quantum particle findings and makes the point that their have not been any major experimental discoveries from the European Large Hadron Collider (L.H.C.) over the last 10 years except for the discovery of the Higgs boson. She suggests that physics need to broaden its experimental process beyond those of the L.H.C.
She says that the physic’s community should step back and reflect on why the L.H.C. has not been able to make any more major discoveries.
She also recommends that physics research focus more on the following issues: 1) features of dark matter, 2) the interface between the quantum realm and gravity, and 3) the development of potentially new insights on the foundations of quantum mechanics.
