* Free-falling charged particles 
*Charged particles in a gravitational field
** Paradox of Charged Particles in Free Fall 
*** Question
- ''Do free-falling charged particles emit electromagnetic waves?''
**** Ans. [#r574880e]
- If we consider that the electromagnetic field created by a free-falling charged particle is also free-falling, pulled by gravity, then no paradox arises. (2022/9/10)
-- Thus, a free-falling charged particle does not emit electromagnetic waves.

*** Another question
- Do charged particles at rest in a gravitational field emit electromagnetic waves?
- https://en.wikipedia.org/wiki/Paradox_of_radiation_of_charged_particles_in_a_gravitational_field

**** Ans. [#e71b455e]
- Again, the field created by the charged particle is stationary with respect to the charged particle, so it does not emit electromagnetic waves. (2022 9/17)
