Discussion Overview

The discussion centers on the mechanisms of electric attraction and repulsion at subatomic scales, particularly through the lens of quantum electrodynamics (QED) and Feynman diagrams. Participants explore the interpretation of these diagrams and their implications for understanding forces between charged particles.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant suggests that in Feynman diagrams, like-charged particles repel each other by "blasting" photons, raising a question about how this applies to electric attraction.
  • Another participant clarifies that Feynman diagrams serve as shorthand for mathematical calculations rather than literal representations of particle interactions.
  • A third participant warns against relying on verbal explanations for subatomic phenomena, emphasizing the complexity of their mathematical descriptions and referencing a specific text for further reading.
  • A link to an external resource is provided, which is described as a good overview of the concept of virtual particles in physics.

Areas of Agreement / Disagreement

Participants express differing views on the interpretation of Feynman diagrams and the nature of subatomic interactions, indicating that multiple competing perspectives remain without a clear consensus.

Contextual Notes

Participants acknowledge the limitations of verbal explanations in conveying the complexities of subatomic interactions and the reliance on mathematical frameworks for accurate descriptions.

TL;DR
What is going on in electric attraction Feynman diagrams?
In Feynman diagrams, I believe two like-charged particles will "blast" one another with a photon, thus pushing each other away because of the law of conservation of momentum. How would this work for electric attraction?

A Feynman diagram is not a picture of what gets "blasted". It is shorthand for a term in a mathematical calculation.

It's a bit "risky" to ask for verbal explanations about subatomic phenomena and/or their mathematical description. As Vanadium 50 said, Feynman diagrams fall into that category.

However, if you only worry about how to describe both attractive and repulsive events in QED, you can find a nice passage in Zee's "QFT in a Nutshell, 2nd ed.", section I.5; it's on the math side, but the text between the equations is readable.
