Think Globally - Observe Locally.
4 th International Sakharov Conference on Physics.
Gravity apparently does not permit precise local observables,
yet in the cosmological context we are constrained to observe
locally. This talk will describe aspects of the problem of formu-
lating gauge invariant observables that are approximately local,
using relational ideas. Their relevance in quantum de Sitter
space will be briefly discussed, together with what appear to be
intrinsic limitations on such locality.
