Discussion Overview

The discussion centers around the question of whether there is gravitational interaction between two photons, exploring theoretical implications and references to existing literature.

Discussion Character

  • Exploratory, Technical explanation

Main Points Raised

  • One participant questions if gravity exists between two photons.
  • Another participant suggests that gravity may exist if the photons are not moving in the same direction, referencing a previous discussion for support.
  • A third participant mentions an argument found in Zee's Quantum Field Theory book, indicating that there are established discussions on the topic in academic literature.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants present differing views on the conditions under which gravitational interaction between photons may occur.

Contextual Notes

The discussion references external sources and literature, which may contain assumptions or definitions that are not fully explored within the thread itself.

Thanks!
 
There's also an argument in Zee's QFT book, pages 427-428.
