Discussion Overview
The discussion revolves around a new geometric version of quantum field theory and its potential implications for understanding quantum gravity. Participants explore the connections between large- and small-scale structures in the universe and the breakdown of locality and unitarity.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- Some participants suggest that the new geometric version of quantum field theory may aid in developing a theory of quantum gravity.
- There is a discussion regarding the intuitive argument that locality and unitarity must break down, with some finding the conclusion plausible but the argument itself unconvincing.
- One participant notes the absence of a formal paper on the topic, referencing a video from SUSY 2013 and slides related to the Amplituhedron.
- Another participant mentions two papers by Arkani-Hamed concerning the positive Grassmannian, indicating that the content may be complex and challenging to understand.
Areas of Agreement / Disagreement
Participants express varying levels of understanding and skepticism regarding the arguments presented, indicating that multiple competing views remain and the discussion is not resolved.
Contextual Notes
There are limitations regarding the lack of formal publications on the new geometric version of quantum field theory, and the discussions rely on interpretations of complex concepts that may not be universally understood.
