Feynman diagrams for Quantum Gravity

Click For Summary

Discussion Overview

The discussion centers around the application of Feynman diagrams to General Relativity, specifically exploring a proposed idea that may lead to renormalizable diagrams by exchanging renormalizability with non-locality. Participants are invited to calculate quantum amplitudes based on this idea and share their results.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Diego Marin proposes an idea that could yield renormalizable Feynman diagrams for General Relativity by trading off renormalizability for non-locality.
  • Diego invites others to calculate quantum amplitudes based on his proposal and share their findings.
  • Some participants express concerns about adherence to forum rules regarding the initiation of discussions.
  • There is a mention of an upcoming paper to be published on ArXiv, with questions about the appropriateness of sharing this information in the forum.

Areas of Agreement / Disagreement

Participants express differing views on the appropriateness of the discussion's initiation and the sharing of unpublished work, indicating a lack of consensus on these procedural aspects.

Contextual Notes

There are unresolved questions regarding the acceptance of sharing pre-publication work and the implications of the proposed idea on the established understanding of quantum gravity.

Dear collegues,

I want to share with you a little idea which permits to obtain (almost apparently) renormalizable Feynman diagrams for General Relativity. (See attached file) This idea exchanges renormalizability with non-locality. I'll vary fain if someone of you will try to calculate any quantum amplitude. Please share your results too. Thank you for attention. I hope do not violate the forum rules with this post.

Diego Marin (Ph.D.)

I have read. This paper will be published tuesday on ArXiv. There are two days of advance: are they acceptable?
 
with this additional information I would say 'yes' ;-)
 
I'll put a link to paper on arXiv as it becomes available. Thank you for your patience.
