Lec. 42 notes
... There are actually eigenstates of any measurable quantity; not just energy. If you measure a quantity other than energy (like position, momentum, angular momentum, …) then the particle will be in an eigenstate of that quantity (and not necessarily of energy). If we measure the position in an infinit ...

This geometry will have no horizon or singularity and might look nothing like the black hole that we wanted to consider. But it has the same mass and charges as the hole, and in string theory one can ...
