Polchinski extended work on chaotic behavior from eternal versions of these objects to show that they may have an anomalous energy flux. A proposed solution to a problem in which these objects can turn pure states into mixed states is summarized in the phrase EPR=ER. In 2015, three researchers used BMS super-translations to solve a problem about how the formation of these objects violates S-matrix unitarity. Those problems are their firewall paradox and their (*) information paradox. They are characterized by mass, charge, and angular momentum only. Energy may be extracted by rotating ones via the Penrose process, and those rotating ones are described by the Kerr metric. For 10 points, name these objects which are formed when mass is compressed to within its Schwarzschild radius.
