I have no idea, Régis. If I knew, I would use that knowledge to deliver this article in everyone's Medium Daily Digest of course. Perhaps one of the topics I used triggered your Medium account as this being of some interest to you.
I have a model to promote, and not many people can believe there is indeed another model possible for Black Holes. That means I have a lot of convincing to do.
Fortunately, Occam's razor favors the Black Eye model because everything in the model is accounted for, scientifically. Meanwhile, the Black Hole model contains a scientific horizon beyond which our scientific instruments cannot peer. As such, we have a Santa position inside the Black Hole model, and Occam's razor does not like Santa positions if there is a model available without Santa positions.
Black Hole model:
1. masses in a galaxy
2. gravitational phenomenon
3. horizon beyond which instruments can't peer
Black Eye model:
1. masses in a galaxy
2. gravitational phenomenon
