SUMMARY:An Observer in De Sitter Space
LOCATION:Zoom
DESCRIPTION:Abstract: In quantum mechanics we usually consider the observer to be exter
 nal to the system being studied, but in the context of gravity, especially 
 in a closed universe, it may be necessary to explicitly take into account t
 he observer and the observer's gravity.  After a general discussion of what
  an observer can observe, I will describe the example of de Sitter space, w
 here it is necessary to explicitly take into account the gravity of the obs
 erver.   (This example was analyzed in arXiv:2206.10780 with V. Chandrasekh
 aran, R. Longo, and G. Penington.)\n
