Quantum Field Theory -- Does electron have infinity size?

Click For Summary
SUMMARY

The discussion centers on the nature of electrons in Quantum Field Theory (QFT) and Quantum Electrodynamics (QED). Art Hobson's assertion that quanta propagate in space to infinity is clarified by emphasizing that "propagate" does not equate to size. In QFT, electrons are defined as point-sized particles, confirming they do not possess infinite size. The conversation concludes with a reminder of the importance of referencing claims for productive discourse.

PREREQUISITES
  • Understanding of Quantum Field Theory (QFT)
  • Familiarity with Quantum Electrodynamics (QED)
  • Knowledge of particle physics terminology
  • Ability to interpret scientific claims and references
NEXT STEPS
  • Research the concept of point particles in Quantum Field Theory
  • Explore the implications of particle propagation in QFT
  • Study the differences between classical and quantum descriptions of particles
  • Investigate the role of references in scientific discussions and debates
USEFUL FOR

Physicists, students of particle physics, and anyone interested in the foundational concepts of Quantum Field Theory and the nature of elementary particles.

Even if he said that, "propagate" does not mean "size".

You need to pay attention and be careful with what you read and what you are interpreting. In QFT (and QED), elementary particles such as electrons are point size particles. They definitely do not have "infinite size".

If you can't give a reference, we don't have a basis for any useful discussion.
