SUMMARY
The discussion centers on whether a stationary charge in a gravitational field emits radiation, referencing the equivalence principle (EP) and Larmor's formula. Participants debate the application of the EP to charged particles, with some asserting it does not apply, while others cite research by Amos Harpaz and Noam Soker (1999) that suggests it does. The conversation also touches on the complexities of measuring radiation from such charges and the implications for conservation of energy. Key references include arXiv papers on electromagnetic self-force and the local nature of the EP.
