The picture is beautiful but I feel that it doesn't convey the right mental model of the black hole.
It would be a great picture to illustrate gravitational lensing, but it's a not so great one for conveying what a black hole is.
From the picture it seems that particles are swirling around in multiple directions, whereas the mental picture you should get is : there is a standard accretion ring but with gravitational lensing visual filter turned on.

- mcv 7y agoA black Saturn wouldn't do it justice. Saturn doesn't bend space as extremely as a block hole does, and it's that extreme bending of space that's the hard part to visualise about a black hole. It's trivial to imagine a black ball with a ring around it, but it's the bending of space and the subsequent bending of light that's the hard part.
- GistNoesis 7y agoYep bending of light and warping is hard to visualize. Thankfully we can play with our own black hole at home. I took my crystal ball cut some cardboard into a ring. If you look, you can see both side of the ring behind the black hole : https://gistnoesis.github.io/blackhole.jpg https://gistnoesis.github.io/blackhole.jpg You just need to imagine a little stronger warping.
