Total Charge of the Universe

[Antonio Lao]

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

Is the charge conjugation symmetry broken in the elementary particles?

[Janitor]

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.
