Hi ManitouLance! Thanks for contributing to Wikipedia. Come join other new editors at the Teahouse! The Teahouse is a space where new editors can get help from other new editors. These editors have also just begun editing Wikipedia; they may have had similar experiences as you. Come share your experiences, ask questions, and get advice from your peers. I hope to see you there! Benzband (I'm a Teahouse host)

Paradox of a charge in a gravitational field

[edit]

I think the radiation of a free falling charge is still an open question.

I didn't know the explanation of your article. It is for sure consistent, but there is at least a second explanation, at least equally valid, which is based in the Feynman radiation equation.

Classic radiation equation is obtained assuming that a charge does not interact with its own field. Feynman equation does not assume this and obtains a different expression for the radiation [1]

Though maybe it is surprising, there is no experiment that measures directly if an uniformly accelerated charge radiates in an inertial frame. Classic electromagnetic theory says it should, but this has never been confirmed by an experiment, because experiments use circular accelerating charges to verify the classic radiation equation.

For sure, classic equations yield the correct result for circular accelerating charges, but Feynman radiation equation yields the same value in these cases. The big difference is that it yields no radiation for an uniformly accelerating charge seen from an inertial frame.

Should Feynman be right, the accelerated charge would not radiate in any frame. This explanation is also consistent, and besides, it preserves energy in any frame without using the Boulware explanation (I thinks it is cleaner). Therefore, I think the article should be extended with at least this alternative explanation.

User_talk:ManitouLance - Please have a look at this Talk:Kaluza–Klein_theory#Modern_generalizations_of_Kaluza-Klein_theory (talk page) and see if this proposed revisions of the section (Modern generalizations of Kaluza-Klein theory) may be worth including in the Kaluza–Klein_theory article.
