DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/69/">T
 he Timelike Tube Theorem</a>\nby Edward Witten (Institute for Advanced Stu
 dy) as part of NHETC Seminar\n\n\nAbstract\nI will explain the ideas invol
 ved in the timelike tube theorem\,  which says that the algebra of quantum
  fields along the worldline of an observer is the same as (roughly)  the a
 lgebra of quantum fields in a spacetime region that is causally accessible
  to the observer. The earliest version was proved by Borchers and Araki in
  the 1960's.\n
