The discussion centers on whether black holes act as "matter sprinklers," specifically examining if the mass of jets emitted by black holes is smaller or larger than the mass they consume from surrounding accretion disks. Participants conclude that the total mass emitted is smaller, primarily due to thermal radiation and the dynamics of accretion processes. They emphasize that jets are external phenomena unrelated to the black hole's event horizon, and while some mass-energy conversion may occur, the net mass of the black hole decreases over time. Key references include the Penrose process and the role of magnetic fields in jet formation.
PREREQUISITESAstronomers, astrophysicists, and students of theoretical physics interested in black hole dynamics, accretion processes, and the nature of relativistic jets.
Chronos said:Hawking radiation consists of photons, not particles.
