the light from the side of the black hole facing away from us, is also curved back and thrown towards us, when looking at the black hole from the side
What does it mean to look at a black hole "from the side"?
- caf 7y agoPerpendicular to its spin axis (black holes have angular momentum, which is a vector).
- mr_toad 7y agoDoes the ‘equator’ of a spinning black hole have any relationship or influence on the accretion disc? Or vice versa? Is the direction of spin of a black hole even knowable?
- caf 7y agoThe spinning black hole drags space around it, which certainly distorts the accretion disc.

- taneq 7y agoIt doesn't really make sense to refer to the 'side' of a black hole itself, but I'd guess they mean 'close to the plane of its accretion disk'?
- mr_mitm 7y agoThey mean the light emitted by the section of the accretion disk that is behind the black hole takes a path such that it meets the observers eye. I. e. space is curved so that we can see behind the black hole.
- Already__Taken 7y agoShouldn't there be a photon ring no matter what? Accretion disk or not? Wouldn't all light in the universe get collected into a photo ring?
- SiempreViernes 7y agoThe photon ring is just one possible stable orbit. Just like there is nothing that forces all the stars to orbit our sun, there is nothing forcing the universe to place all the photons in the universe into one stable orbit around a black hole.
