[edit] Introduction

(William M. Connolley 17:31, 2004 May 26 (UTC)) Errrm... is this page dodgy? It starts off by saying that inside BH's classical thermo breaks down. Then it derives a pile of things using classical thermo. Then electrons go back in time.

I have no recollection of editing the intro; but I clearly did about six months ago. So you may rightly be suspicious of that bit. Charles Matthews 18:32, 26 May 2004 (UTC)

[edit] Request for review

Requesting someone who is experienced in astrophysics looks over this article, becuase it's quite confusing and I'm not sure if it's all correct (September 2006) —The preceding unsigned comment was added by 86.133.225.32 (talk • contribs) on 23:02, 31 August 2006.

To whoever is willing to improve the article, here is a link to a review article: Don N. Page, Hawking radiation and black hole thermodynamics, New Journal of Physics 7 (2005) 203.[1].  --LambiamTalk 18:16, 29 October 2006 (UTC)
Thanks (although the link seems to be broken), I plan on improving this article sometime, only I can't say when. I have a copy of Wald's 1994 Quantum Field Theory in Curved Spacetime and Black Hole Thermodynamics, which I will use to clean this article (although I still like to find one more book). Later: --Sadi Carnot 19:38, 1 November 2006 (UTC)
Sadi, I recommend the book by Birrel and Davies: Quantum Field Theory in Curved Space. -Joshua Davis 23:01, 13 January 2007 (UTC)

Some sample calculations would be helpful, as the proper units to use are not obviouus to persons trained in other fields. ie mass in kilograms, distance in meters, gravity in meters per sec, per second k =? 12:02, 5 September 2007 (UTC) —Preceding unsigned comment added by Ccpoodle (talk • contribs)

[edit] Proportionality

Shouldn't we say that the constant of proportionality is approximately 1/4, up to quantum gravity corrections, or is it somehow proven to be 1/4 regardless of what gravity looks like at Planck scale? Itinerant1 03:00, 12 January 2007 (UTC)--

There have indeed been cases studied where quantum corrections change it from 1/4. But this may be too technical to get into here. PhysPhD 06:42, 19 May 2007 (UTC)

[edit] Deleted "Problems" sections

There may be some parts of these sections that could be salvaged, but they were way below the bar as they stood. All that stuff with waves and rolling dice was some author making stuff up.PhysPhD 06:42, 19 May 2007 (UTC) It was all quoted from Hawking sciam (not physical review) article, so i dont know ho you might consider it making stuff up, the work about the duality of time arrows comes from Santa Fe institute work done by gellmann and George west (nobel prize and ex-president of alamos lab), so it is not original research, the general view of relativity comes from Gravitation by Wheeler, i will repost latter a shorter version. I acknoledge english is not my first language, but also a need in this encyclopedia of better defined concepts - most people dont undestand its mathematics, and critical opinions (which is idfferent fro oroginal research). That is what the britannica and larousse have and wikipedia lacks because most students who work here tend to have limited knowledge to do those improvements, which however distinguish a truly good encyclopedia like those 2 - —Preceding unsigned comment added by 76.89.242.7 (talk) 01:10, 23 February 2008 (UTC)
