Abstract

Abstract: We study the deformation of the horizon‐vicinity geometry caused by quantum gravitational effects. Departure from the semi‐classical picture is noted, and the fact that the matter part of the action comes at a higher order in Newton's constant than does the Einstein‐Hilbert term is crucial for the departure. The analysis leads to a Firewall‐type energy measured by an infalling observer for which quantum generation of the cosmological constant is critical. The analysis seems to suggest that the Firewall should be a part of such deformation and that the information be stored both in the horizon‐vicinity and asymptotic boundary region. We also examine the behavior near the cosmological horizon. Abstract : The deformation of the horizon‐vicinity geometry caused by quantum gravitational effects is studied.
