I stumbled upon this article in phys.org
They write about a new paper -Scalar Field Dark Matter in Clusters of Galaxies
quote:
"For larger galaxies, a more complicated model of fuzzy dark matter has been needed. In this model, massive concentrations of dark matter can lead to multiple quantum states (called "excited states"), in which the dark matter particles can have different amounts of energy, similar to an atom with electrons in higher energy orbits. These excited states change how the density of dark matter varies with distance away from the center of the galaxy cluster."
Isn´t that similar to what Mills is suggesting with his hydrino?
