Discussion Overview
The discussion revolves around the concept of light orbiting black holes and whether it could become "crowded" over billions of years. Participants explore the implications of light's behavior in the vicinity of black holes, touching on theoretical and conceptual aspects.
Discussion Character
- Exploratory, Conceptual clarification, Debate/contested
Main Points Raised
- One participant questions if light could become crowded around a black hole over time due to its continuous influx from all directions.
- Another participant argues that orbits of light around black holes are not stable, as even minor gravitational disturbances cause light to fall into the black hole, preventing any accumulation.
- A different viewpoint suggests that only photons created or reflected at the orbital radius could maintain a stable orbit, aligning with the previous claim about instability.
- One participant asserts that the crowding of light leads to the formation of quasars.
- Another participant claims that the photonsphere of a black hole is an illusion and lacks physical reality, comparing it to a rainbow.
Areas of Agreement / Disagreement
The discussion features multiple competing views regarding the behavior of light around black holes, with no consensus reached on the implications of crowding or the nature of the photonsphere.
Contextual Notes
Participants express varying assumptions about the stability of light orbits and the physicality of the photonsphere, which remain unresolved.
