I was watching Sabine Hossenfelder’s video titled I stopped working on black hole information loss. Here’s why. It inspired some ideas.
A black hole’s charge and angular momentum would cause a magnetic field (Maxwell’s Law) to accelerate accreting matter into relativistic jets, as we can observe. Matter spirals around, orbiting the black hole’s equator, and falls inward toward the black hole event horizon. Some or all of this in-falling matter is redirected to jets firing out from the poles of black hole, and this matter is accelerated to relativistic speeds (near the speed of light). This involves a huge transfer of energy from the black hole to the matter from the accretion disc.
Could that transfer of energy carry information away from the black hole? Maybe this hypothesis isn’t sufficient by itself to explain how a black hole’s mass shrinks — only how its angular momentum slows.
We can also hypothesize the magnetic field is strong enough to produce pairs of particles that add to the jets. Photons of the magnetic field collide to create electron-positron pairs. Now we have a mechanism, pair production, for mass to escape the black hole in a manner that is distinct from Hawking (thermal) radiation. That would be how information flows out, so it is not lost.
