The lack of classical Cepheids in the inner part of the Galactic disk.

The suggestion for the origin of: "the lack of classical Cepheids in the inner part of the Galactic disk" is: the lack of massive Herbig Haro systems between massive SNova black holes. which are systematically ejected out of the Galaxy Disc, according to Quantum FFF Theory.
As a result, the smaller BHs stay put in the center of the galaxy, feeding the monster central black hole.see: Preference for Dual Herbig Haro Black Hole Consumption by the Central MW Black Hole, Leaving Plasma Jets Behind.

The Origin of Hexagonal structure of laser light?

Light travelling through the oscillating Axion Higgs particle based tetrahedral vacuum lattice seems to create an hexagonal  effect.

The distance between the two mirrors has influence on the fine-structure of the resulting hexagonal structure observed on the screen.

TWO superpartner Higgs with different masses. 123.5 and 126 GeV.

There are TWO real Higgs supersymmetrical particles (in a rigid string model) found in the LHC which is denied because they have a different mass.,
https://motls.blogspot.com/2019/02/bear-et-al-string-theory-predicted.html
Quote: "the 125GeV Higgs boson, along with the absence of superpartners at the LHC at this point as well as the null results of the dark matter direct search experiments, is exactly what the most conventional string theory scenario – equipped with a naturally sounding refreshed notion of naturalness and a seemingly conservative type of the anthropic veto – has always predicted."
However, Imo, there is no absence of Higgs superpartners in the LHC. there are two partners: 123,5 and 126 GeV. also mentioned in the past by Dorigo.
According to Quantum FFF Theory, There is a mass difference  because the ( Casimir) vacuum oscillations in our materia;l universe have left handedness.

Rigid String Quantum Knots as a base for Bose Einstein Black Holes.

Created by 4x (X-ray) laser or/and 3x E.M. knotty interference.
see: "4x and 3x Interference for Stringy Bose Einstein Black Hole production."
http://vixra.org/pdf/1901.0426v1.pdf

4x X-Ray laser interference or 3x E.M. interference should lead to Bose Einstein knots or (Fenmtosecond) unstable nano Black Holes.
However a combination of both (X ray and EM) interference could become more stable black holes as observed as Sprites and Elves above lightning clouds producing Ball lightning or even micro Comets.

Stable or unstable micro black holes ( comets / ball lightning)

Example of a micro high altitude Comet, a splitting semi stable black hole, pushed by plasma tail, which is assumed to be self produced by pair production at the BH horizon.

Sprite and Elve creation above lightning clouds with ( semi) stable Black hole production ( micro Comets and Ball Lighnting.)

It is well known that both : X-Rays and EM waves are present at that high altitude: the asumed origin of complex String knot black holes.
