The setup is not exactly identical but similar to the Eye of the Storm.

Inside the eye, there is no wind. Yet the Wall of the Eye contains the strongest wind force of the entire storm. So we have a 0 wind force expression in the center, and a 1 wind force (maximum) right next to it. Further away from the center, the storm diminishes in strength and ultimately peters out.

Looking at the Black Eye (Black Hole), the same net-zero situation is found in the exact center, in effect no gravitational output at all. Yet this is true just for that exact center.

Right next to the net-zero spot the strongest gravitational location in the entire galaxy is expressed. Again, a 0 in the center, and a 1 for maximum right next to it.

Matter will in most cases be deflected away from the center, but matter can also fall into the net-zero spot.

That is then similar to an airplane able to get inside the eye of the storm. It takes flying skills, however, to not end up in an accident while trying to fly out of the eye, into the Wall of the Eye.

Matter falling into the Black Eye is simply moving the way it is moving, no controls are in place, and this matter will bump into the Wall, unable to get out. The gravitational monster works against that piece of matter getting out of the Black Eye center. That matter will end up breaking down in pieces.

The exact center is net-zero, but the two perpendicular jet locations are also net-zero. The sources for this net-zero spot is based on all matter in the galaxy. As such, the jets are also the locations with net-zero gravity.

In other words, when a mass is torn to shreds inside the Black Eye (by the Wall of the Eye), then this matter can indeed escape quite easily via the jet paths, while larger chunks may get thrown into the Wall of the Eye, passing through it. Most likely we will not detect these chunks, but who knows we may one day.

Torn-up matter that is moving outwardly via the jet pathways are 'walking' the straight and narrow of that net-zero. Any matter that is not going exactly in that perpendicular direction will fall toward the pull by the entire galaxy in that specific direction. If a piece of torn matter moves just a tiny bit to, say 3 o'clock, then all masses in the galaxy from 1 to 5 o'clock will pull that little chunk into that 3 o'clock direction more. Only in the exact center (and the jets) are all gravitational forces neutralized.

It also explains the image we see of Black Holes/Black Eyes.

Photons are not capable of moving in a straight line due to the enormous gravitational forces experienced at the Wall of the Eye.

Inside the Eye, a photon would have no problem doing what it normally does, but the point is that no photon can get to the center spot.

That is like a butterfly not having any problem at all to move around in the Eye of the Storm because there is no wind in the Eye. Yet the butterfly cannot get there from the outside because the Wall of the Eye will blow the butterfly into another direction.

Same for the photons. They cannot make it to the center, hence a Black Eye. No photons.

The ring around the Eye, however, is lit up, a ring of light is visible. These are the photons that are blown off course into our direction.

Keep in mind that we cannot see photons that do not come into our direction. We only see photons that come into our direction.

So, the photons in the ring of light pinpoint us very nicely to where the actual gravitational monster is lurking. They light up the monster itself.
