Discussion Overview

The discussion revolves around the conjecture presented by Michael Hewitt regarding the non-existence of black holes in M theory and the proposal of a gravity regulation mechanism that prevents black hole formation. The implications of this conjecture for string theory and quantum gravity are explored, alongside concerns about the credibility of the author and the validity of the ideas presented.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Michael Hewitt proposes that black holes do not exist in M theory and suggests that a mechanism based on string condensation could prevent their formation.
  • Hewitt's scenario posits that black holes could be replaced by 'hot holograms' during gravitational collapse, which may resolve issues related to black hole evaporation and quantum information theory.
  • Some participants express skepticism about the implications of Hewitt's paper for M theory, questioning its validity as a candidate theory of quantum gravity due to its claims about black holes.
  • Concerns are raised regarding Hewitt's credentials, with one participant noting his limited publication history and lack of citations, leading to doubts about the seriousness of the ideas presented.
  • There is a discussion about the perception of the firewall concept, with some participants suggesting it is viewed as a flawed idea by many in the field, yet Hewitt's paper reverses this view by asserting the reality of firewalls over black holes.
  • A request for input from string theorists is made, indicating a desire for expert commentary on the proposed ideas.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the validity of Hewitt's claims or the implications for M theory. There are competing views regarding the credibility of the author and the acceptance of the ideas presented.

Contextual Notes

Participants express uncertainty about the implications of the proposed mechanism and the status of black holes in the context of M theory. Concerns about the author's credentials and the fringe nature of the ideas contribute to the unresolved nature of the discussion.

Who May Find This Useful

Readers interested in theoretical physics, string theory, quantum gravity, and the ongoing debates surrounding black holes and firewalls may find this discussion relevant.

String condensation: Nemesis of Black Holes?
Michael Hewitt
(Submitted on 11 Oct 2015)
This paper puts forward a conjecture that there are no black holes in M theory. We will show that a mechanism to prevent black hole formation is needed in 4 dimensions to make string theory a viable high energy model of quantum gravity. Black hole formation may be averted by a gravity regulation mechanism based on string condensation. In this scenario, black holes are replaced by `hot holograms' that form during gravitational collapse. The geometric conditions based on the properties of free thermalon solutions that are proposed for conversion to a high temperature hologram to occur, however, are local and generic in dimension and could apply throughout M space. This idea can be applied to resolve the problems presented by the process of black hole evaporation, which appears to be inconsistent with quantum information theory. Whereas, in the conventional view, black holes are real and firewalls are probably a chimera, in the scenario proposed here that situation would be reversed.

Marcus what are the implications of the paper to m-theory as a candidate theory of QG? that it does not correctly describe black holes contrary to observation and is therefore not a candidate theory of quantum gravity
 
Kodama, I am worried about this guy's credentials. He has only published one paper, in 1993. And it has only been cited by himself, in his own unpublished papers. He does not have the recognition by colleagues or the track record of people whose work I ordinarily start a thread about. So I have been wondering if I should erase this thread. What caught my attention was the very strange idea that the firewall (which most people think is a mistaken idea, symptomatic of some flaw in theory) is real and the BH is not. What should I do? Do you think I should delete this thread because too fringe, too wacky? He is a string theorist. I do not feel qualified to judge.
