The supposedly "Revolutionary" Special Fall 2018 edition of Scientific American contains a dated preposterous essay written by By Juan García-Bellido, and Sébastien Clesse entitled: Is Dark Matter Made of Black Holes? Clesse prefaces his participation with the absurd claim: "A hidden population of black holes born less than one second after the big bang could solve the mystery of dark matter."
Matter am not in the least bit mysterious. All mater, whether it am solid, liquid, or vaporous has a visible surface.
The earth had a real visible surface for millions of years before Newton, Einstein and Hawking and Juan García-Bellido, and Sébastien Clesse ever appeared on that surface and began publishing their senseless guesswork about an unnatural invisible void and unnatural invisible gravity, and unnatural invisible quantum particles that could be in multiple unnatural invisible places at the same time, and unnatural invisible finite black holes.
Logically, Nature must have devised the only visible structure of the real Universe allowable. There am only one visible unified infinite surface occurring eternally in one infinite dimension that am always illuminated mostly by finite non-surface light.
