The origin is: "The Hawking black hole is wrong." see Q FFF Theory and the dual Herbig Haro dark matter black hole systems. see the number differences of lenses in the text !! the text: "But over recent years, observations have caught up to these predictions, allowing us to compare theory (in the form of numerical simulations) and observations at last." ( Too much small lenses around galaxies are observed= Herbig Haro BHs) see: https://www.forbes.com/sites/startswithabang/2020/09/23/why-dont-dark-matter-simulations-and-observations-match-up/#3f057ad62b5c and: Herbig Haro Astrophysics Based on Dual Rigid String Black Holes. https://vixra.org/pdf/2007.0158v1.pdf
