SUMMARY
An accelerating electron radiates when its trajectory changes, including when it curves past a massive body due to spacetime curvature. This phenomenon is explained by the need for the electron's electromagnetic field to update as it changes position. In curved spacetime, Maxwell's laws are modified, requiring the use of covariant derivatives to account for geometry. The discussion highlights that even in extreme cases, such as an electron falling into a black hole, the electromagnetic field must communicate changes across distances.
