Dark Matter is apparently 84.54% of our Universe. If this is so abandoned, why did the millions we spend looking for it did not yield anything ?

Lets see:

If you go through the list of papers on the Michelson-Morley experiment, you will see that it is not that clear. In fact, they did a lot of things wrong then. Averaged values that should have not been, missing information about the movement of the solar system
around the galaxy core (~360 km/s), gas mode instead of vacuum,...

There are many critical papers published over the years:

This is a very nice list of better experiments, looking into those is very interesting:

Einstein only later understood, that general Relativity without aether is unthinkable (Sidelights on Relativity):
"""
Recapitulating, we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an ether. According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring-rods and clocks), nor therefore any space-time intervals in the physical sense. But this ether may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time. The idea of motion may not be applied to it.

He did not need aether for SR, but GR without aether, simply does not make sense. Also radial waves as predicted by Lord Kelvin and discovered by Tesla are not really understandable without. You can explain many virtual particles by creating a zoo like the standard model did, but radial waves you can't.

Dark Matter is the aether, without it's mass, spiral galaxies and many other cosmological phenomena are not explainable - or at least not classical.

The problem with most aether theories is, that they assume it as some sort of superfluid, or some special substance, which both do not make so much sense, as the complexity of the vacuum is simply to great. It must at least implement all virtual particles (β+/β-/photons/...), electric and magnet fields (Hertz & Tesla waves, as both exist),...

The BSM-SG model has a completely different aether model, instead of some special substance, it is made of the same building materials as protons/electrons, just in a much smaller and different geometric structure.

It has only one fundamental force and 2 very simple fundamental particles (balls). It becomes clear, that already quite large crystals, that look like prisms, under this one law of attraction, build a grid that looks like a 3d honey web.

In this grid, you can find all the physical properties we can measure. Electric and Magnet Fields, Speed of Light, Photons, Vacuum Fluctuations, Gravity, Coulomb Barrier, Quantum Entanglement, Virtual Particles (without rest-mass)....

Of course, many of those are iterations between the extremely complex geometrical structure of electrons/protons/neutrons and the Cosmic Lattice as its called in BSM-SG.

Best physics book I read and most sensible unified theory I have encountered so far:

Needs an open mind tho and some months of heavy thinking for really getting into this theory, but once you grasp the basic interactions, geometric structures etc the universe starts to make so much sense.
So far, every phenomena I encountered was explainable after some minutes-days of thinking and I always came to the same conclusion as Stoyan Sarg.

The universe is classic logical :)
