A Brief Comment on Instanton-like Singularities and Cosmological Horizons

High Energy Physics - Theory 2016-09-06 v2

Abstract

We argue that in the presence of instanton-like singularities, the existence of cosmological horizons can become frame-dependent, ie. a horizon which appears in Einstein frame may not appear in string frame. We speculate on the relation between instanton-like singularities and the formulation of quantum gravity in de Sitter space.
