Is the Total Electric Charge of the Universe Zero?

AI Thread Summary
The discussion centers on the total electric charge of the universe, questioning whether it is zero, positive, or negative. It also addresses the concept of charge conjugation symmetry in elementary particles. The conversation highlights that K mesons have been observed to violate CP (Charge-Parity) conservation, as well as T (Time) conservation, while emphasizing that CPT (Charge-Parity-Time) symmetry is believed to be conserved across all particle interactions. There is uncertainty regarding whether experiments have isolated the CP violation to charge (C) or parity (P) alone.

Is the total electric charge of the universe zero? Positive? Negative?

Is the charge conjugation symmetry broken in the elementary particles?

As to your second question, as you know K mesons have been shown to violate CP conservation and likewise T conservation. There are good theoretical reasons for believing that CPT is conserved for all particle interactions. Whether experimenters have been able to further break down the CP violation as being due to only C or only P I haven't heard.
 
Janitor,

Thanks for the information.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
