A Brief Editorial on de Sitter Radiation via Tunneling
A. J. M. Medved
Very recently (by which we mean two days ago), Y. Sekiwa submitted a paper [arXiv:0802.3266] that dismisses some previous calculations of the de Sitter radiative temperature. Signi…
An Implication of "Gravity as the Weakest Force"
A. J. M. Medved
The negative specific heat of a radiating black hole is indicative of a cataclysmic endpoint to the evaporation process. In this letter, we suggest a simple mechanism for circumven…
Nearly Degenerate dS Horizons from a 2-D Perspective
A. J. M. Medved
Some recent studies have implied that quantum fluctuations will prevent a near-extremal black hole from ever attaining a state of precise extremality. In this paper, we consider th…
Big Bangs and Bounces on the Brane
A. J. M. Medved
In view of our accelerating universe, one of the outstanding theoretical issues is the absence of a quantum-gravitational description of de Sitter space. Although speculative, an i…
Bad News on the Brane
A. J. M. Medved
There has been substantial interest in obtaining a quantum-gravitational description of de Sitter space. However, any such attempts have encountered formidable obstacles, and new p…
Asymptotically Flat Holography and Strings on the Horizon
A. J. M. Medved
Recently, Klemm and others [hep-th/0104141] have successfully generalized the Cardy-Verlinde formula for an asymptotically flat spacetime of arbitrary dimensionality. And yet, from…
