Why is Electric Charge Quantized?

Click For Summary
SUMMARY

The quantization of electric charge is fundamentally explained through various theoretical frameworks, including Kaluza-Klien Theory and Grand Unified Theories (GUTs). In Kaluza-Klien Theory, charge arises from the discrete momentum values associated with a curled-up dimension, analogous to the particle in a ring problem. Additionally, in many GUTs, the requirement of charge quantization is derived from the properties of the underlying Lie algebra, similar to how SU(2) necessitates quantization of angular momentum. Comprehensive explanations can be found in discussions by Urs Schreiber on sci.physics.research.

This is why electric charge is quantized.

Hey Marlon !

this is not a short way to the quantiziation. I don't see the point here.

this is meant as an answer for the question posted in the research-branch of this forum. But there i cannot post attachements

Urs Schreiber has put up a comprehensive explanation on sci.physics.research.
 
There are other ways of obtaining charge quantization. In Kaluza-Klien Theory it comes naturally, since the curled up dimension has discrete momentum values (this is basically the particle in a ring problem), and the momentum component in the fifth dimension is charge. In many GUTs it comes about because the lie algebra requires it, in the same way that the lie algebra of SU(2) requires that angular momentum be quantized.

yes i know, copying is not to difficult though
