Charged Charged particle Particle Radiation

Click For Summary

A single charged particle in free fall into a black hole is theorized to radiate due to its acceleration in a gravitational field, a phenomenon related to electromagnetic radiation. The discussion emphasizes the need for a solid understanding of general relativity and quantum field theory to address this question effectively. Participants are encouraged to explore previous inquiries on the topic, as it has been a recurring subject in physics forums. The complexity of the interaction between charged particles and black holes necessitates a careful approach to formulating an answer. Overall, the topic highlights the intersection of gravitational physics and electromagnetic theory in extreme environments.

What - if any - effort havce you put into answering this? (Hint: it's been asked many times right here on PF) We need to know where to start our answer.

Thread 'Physical Interpretation of Frame Field'

Moderator's note: Spin-off from another thread due to topic change. In the second link referenced, there is a claim about a physical interpretation of frame field. Consider a family of observers whose worldlines fill a region of spacetime. Each of them carries a clock and a set of mutually orthogonal rulers. Each observer points in the (timelike) direction defined by its worldline's tangent at any given event along it. What about the rulers each of them carries ? My interpretation: each...
