charge definition

I don't see the point of this last chapter... Could it be better explained? Thanks

Merge with C parity or vice-versa? Headbomb {ταλκ – WP Physics: PotW} 05:29, 20 June 2008 (UTC)[reply]

Yes, please. Besselfunctions (talk) 16:27, 30 September 2008 (UTC)[reply]

No, definity not. C Parity is not the same thing as C-symmetry. There is an issue of whether or not light and gravity are c-symmetric that needs to be resolved first, which I address below130.207.180.80 (talk) 13:13, 25 November 2008 (UTC)[reply]

Gravity is not C-Symmetric

I put up a dubious text because I honestly belief that gravity is not C-symmetric. As a physicist I have generally learned that anti-gravity is not possible because gravity has no charge conjugate since its charge is zero. If there is a source of information that shows gravity to be C-symmetric you need to cite an example.

Furthermore there need to be clarification on the word electromagnetism vs. the phrase "electricity and magnetism". Do you mean the quantum mechanics of electricity and magnetism or the quantum mechanics of optics? While Electricity and magnetism both have charge and produce something called Electromagnetism, Electromagnetism in itself lacks charge because the photon and the electromagnetic wave lacks charge even though the electromagnetic waves components have charge. In fact to my knowledge if electromagnetism is C-symmetric then wouldn't that mean anti-photons exist? 130.207.180.80 (talk) 13:13, 25 November 2008 (UTC)[reply]

I corrected the spelling errors and grammatical errors, I made before. (talk) 09:51, 8 December 2008 (UTC)[reply]

When we say 'gravity is C-symmetric' we mean that gravitational interactions conserve C-symmetry, and the same goes for electromagnetism etc. I have no idea what you mean by 'the wave components have charge', if that makes sense - perhaps you could clarify that. Electromagnetism is C-symmetric, and anti-photons do exist: they are called 'photons'.
