It was a good week for physics research as work by two teams of theorists working independently may have solved Stephen Hawking’s black hole paradox. The first demonstrated that black holes are more complex than thought, while the second followed up on work by the first suggesting that their proposed “quantum hair” resolves the paradox. Also, a team at Pennsylvania State University developed a novel theory of entropy that may solve materials design issues. Called Zentropy, it involves predicting the change of volume as a function of temperature at a multiscale level. And a team at the University of Nevada, Las Vegas discovered a new form of ice, adding to the 20 known solid forms.
