Discussion Overview

The discussion revolves around the implications of the AdS/CFT correspondence in modern theoretical physics, with a focus on various theoretical frameworks and models, including loop quantum gravity, M-theory, and others. Participants explore the interplay between these theories and their potential applications in fields such as black hole thermodynamics and cosmology.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants propose various complex titles for theoretical papers that incorporate multiple advanced concepts, such as "doubly special relative locality" and "E8-valued spin foam".
  • There is mention of the growth and development of loop quantum gravity (Lqg) since 2010, with some arguing it has achieved a concise formulation and is gaining traction in the research community.
  • Others suggest that Lqg is now distinct from other approaches mentioned, with evidence building for its limits and applications.
  • Some participants express skepticism about the current state of physics, suggesting there are challenges in the field that need addressing.
  • There are competing views on the relevance and impact of various theoretical approaches, with some being actively researched while others appear stagnant.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the implications of the AdS/CFT correspondence or the current state of theoretical physics. Multiple competing views and models are presented, reflecting a range of opinions on the relevance and future of these theories.

Contextual Notes

The discussion highlights the complexity and evolving nature of theoretical physics, with references to specific frameworks and their development over time. Limitations in understanding and the potential for future research are acknowledged but remain unresolved.

Who May Find This Useful

This discussion may be of interest to researchers and students in theoretical physics, particularly those focused on quantum gravity, string theory, and related fields.

The title just came to me:

"Doubly special relative locality of Bilson-Thompson braids in an asymptotically safe, exceptionally simple E8-valued spin foam"

:biggrin: Mitchell, you forgot some!

"Supersymmetric doubly special relative locality of Bilson-Thompson braids in an asymptotically safe, exceptionally simple E8-valued spin foam M-theory"

yes, and the end of the abstract will say something like this


"We find the prameter z go to infinity but the space disappears and time changes into space. What does that mean, we will tell you in our next paper, if not maybe the one after that. oh, by the way, we might come up with a different scheme alltogether." :cry:
 
Joking aside, there is something interesting to point out about Mitchell's list.
In many ways Lqg is now running in a different field from the others he mentioned. In 2010 loop gravity achieved a definite concise formulation and now in 2011 evidence is building that this has the right limits.
We currently see numerous papers related to testing:

And we also see considerable growth in the number of loop research papers overall:

2002 http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+DK+SPIN%2CFOAM+OR+QUANTUM+GRAVITY%2C+LOOP+SPACE+OR+QUANTUM+COSMOLOGY%2C+LOOP+SPACE+AND+DATE+%3D+2002+&FORMAT=WWW&SEQUENCE= (25)

2010 http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+DK+SPIN%2CFOAM+OR+QUANTUM+GRAVITY%2C+LOOP+SPACE+OR+QUANTUM+COSMOLOGY%2C+LOOP+SPACE+AND+DATE+%3D+2010+&FORMAT=WWW&SEQUENCE= (154)
2011 http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+DK+SPIN%2CFOAM+OR+QUANTUM+GRAVITY%2C+LOOP+SPACE+OR+QUANTUM+COSMOLOGY%2C+LOOP+SPACE+AND+DATE+%3D+2011+&FORMAT=WWW&SEQUENCE= (112 as of 14 August, 7.5/12 of the way thru the year)

For a rough estimate of what the 2011 crop might turn out to be, multiply that 112 figure by 12/7.5. I would guess at least 160.

To be fair, I would say that Lqg is in the same league as Sugra, Noncommutative field theory, Strings-and=branes. These were the main approaches that were assembled together with Lqg for discussion at this year's Zurich conference on Quantum Theory and Gravitation.

Several of the approaches Mitchell mentioned could be interesting and have an impact some time in the future--though currently being worked on by just a handful of researchers. In others, activity seems to have died down for present, though of course that could change.

You are too narrow. I would propose
"AdS supersymmetric Horava-Lifgarbagez doubly special relative locality of Bilson-Thompson braids in an asymptotically safe exceptionally simple E8-valued spin foam M-theory / CFT entropic unparticle D-brane correspondence: Theory and applications for black hole thermodynamics, cosmology, theory of everything, confinement, large-temperature superconductivity, graphens, and stock market"
 
Please do not forget the twistor uprising...

"A twistorial approach to AdS supersymmetric Horava-Lifgarbagez doubly special..."
 
I guess this thread kind of sum up the "trouble with physics, nowadays".

Let me update it with superluminal neutrinos included:
""AdS supersymmetric Horava-Lifgarbagez doubly special relative locality of Bilson-Thompson braids in an asymptotically safe exceptionally simple E8-valued spin foam M-theory / CFT entropic unparticle D-brane correspondence: Theory and applications for black hole thermodynamics, cosmology, theory of everything, confinement, superluminal neutrinos, large-temperature superconductivity, graphens, and stock market"
