Gravity from the blackhole is uniform and as such the mass gradients that you see in thepicture should occur all around it, instead of out at 180
degrees from each other!
Black holes arent theoretical, they've 'seen' them with the Hubble, as much as you can see something that doesnt emit light..
But a picture of a black hole would be similar to the fake one posted here..
We can also indirectly measure them using Einstein's relativity theory and see the light bending..
They have equations which describe Black Holes, see Universe in a Nutshell by Stephen Hawking.. They are quitebasic!
