Feynman Diagrams: Does Distance Affect Electromagnetic Interaction?

Click For Summary
SUMMARY

Feynman diagrams represent spatial relationships in particle interactions, where the horizontal axis denotes distance. The discussion confirms that virtual photons facilitate electromagnetic interactions between particles, regardless of distance, as they are calculational tools rather than physical entities. The creation of virtual photons does not depend on proximity; rather, they serve as a mathematical shorthand in quantum field theory.

PREREQUISITES
  • Understanding of Feynman diagrams and their role in quantum mechanics.
  • Knowledge of virtual photons and their function in electromagnetic interactions.
  • Familiarity with quantum field theory concepts.
  • Basic grasp of particle physics and interactions.
NEXT STEPS
  • Explore the mathematical foundations of Feynman diagrams in quantum electrodynamics.
  • Study the role of virtual particles in quantum field theory.
  • Investigate the implications of distance on electromagnetic interactions in particle physics.
  • Learn about the differences between virtual and real photons in quantum mechanics.
USEFUL FOR

Physicists, students of quantum mechanics, and anyone interested in the principles of particle interactions and electromagnetic theory.

Hello all .
In feynman diagram horizontal direction is space . is that mean distance between particles ?
is that means two electron must be near a certain distance to create a virtual photon ?

Does one electron in Earth send electromagnetism force to one electron on moon by virtual photon ?
Does one electron in Earth has interaction with one electron on moon by electromagnetism force ?

Does virtual photons create in short distance ?
Creation of virtual photon depend on distance between two particles ?

Feynman diagrams are convenient shorthand for terms in a mathematical expression. They are not meant to be an underlying "billiard ball" mechanics of particle behavior.
 
virtual photons are calculational tools,that is why they are called virtual.
