Black Holes and The Constructal Law

Caleb Scharf's book is fascinating.

This astronomer introduces an idea in the title: "Gravity's Engines". Black holes are churning away matter. Matter in and processed  matter out, they do it, by producing factories around them. The holes provide the energy, and I propose here, the designs. Then voilà , we get the Universe as we know it.

The design black holes provide, in my proposal, is Adrian Bejan's  Constructal Law.

According to professor Bejan, flow is such, that flow next time around is better. Matter flow near a black hole, I propose, makes flow better next time around.

What we need and is not provided by Scharf is a design principle. I believe the design principle is the one discovered by Bejan.
