Beyond Dark Matter

Could Mordehai Milgrom help us detect dark matter?

In deep underground laboratories, buried below rock and shielded from cosmic radiation, physicists have build extremely sensitive detectors aimed at solving one of the Universe’s greatest mysteries. They are awaiting signals of a new kind of particle, promised to them by cosmologists and astrophysicists: Dark Matter. The highly elusive particle is thought to dominate the mass budget of our galaxy and of the Universe as such. There should be about six times more Dark Matter than ordinary, “baryonic” matter (which includes everything from interstellar gas clouds, stars, and planets, to the screen you are reading this on, and you yourself). Dark Matter has not yet been directly detected, despite numerous experiments, their painstaking efforts to reduce background signals, and thus ever increasing sensitivity. Many researchers nevertheless remain confident that a detection is within reach. Yet some worry: what if we are chasing a phantom? What if Dark Matter does not exist?

I would like to ask that you consider the following alternative gravity theory as regards dark matter. At the bottom of the page given in the link, there is also a discussion of gravitational lensing and how this theory deals with it.

I think that at a certain galactic distance, gravity reverses and the galaxies begin pushing against each other. This would do away with cosmological expansion, dark matter, and dark energy. This is a claim that can be easily tested:
A revised gravity equation looks like this (I have made an adjustment compared to my last version):

F = (1.047 X 10^-17) m1m2 [-cos(Θ)] / r^2 where tan Θ = r / (1.419 X 10^22)

By playing with the constants, this equation can be fitted and tested against the data of galactic motion. It means that at a certain distance, gravity will reverse and the galaxies will be pushing against each other. This pressure against each other does away with the need for dark matter or dark energy in cosmology.

So the equation can be tested against current data to see if it fits. This equation also predicts that galaxies near the edge of the universe will be deformed -- concave with the concavity pointing towards the center of the universe.

This equation also predicts the existence of isolated galaxies that are far away from other galaxies, that would behave normally without the need to posit dark matter. An example of this type of galaxy is NGC1052–DF2 . Talked about in this article:

So what I am asking is very precise, very narrow, very testable: Someone please test this equation to see if slight adjustment of the constants will account for galactic motion or not. If it does, then proceed to the rest of the theory.

If it cannot, then the theory can be dismissed. Either way, I would like to know -- but I would not be convinced with a simple "absurd!" or dismissal unless it has been tested out.

If it is true that the motion of galaxies can be modeled in this way, I would ask that you take a look at the explanation in this theory:

"What if Dark Matter does not exist?" I have suggested to Professor Milgrom that relativistic MOND is simply the alleged Fernández-Rañada-Milgrom effect, i.e., replace the -1/2 in the standard form of Einstein's field equations by -1/2 + dark-matter-compensation-constant, where this constant is approximately sqrt((60±10)/4) * 10^-5 — however, Professor Milgrom seems to believe the Gravity Probe B science team. I suggest that the Gravity Probe B science team misinterpreted their own experiment. Have pro-MOND researchers carefully studied this issue?

I suggest that the problem with "patch potentials" is merely an imagined explanation for an actual detection of the alleged Fernández-Rañada-Milgrom effect. I have suggested to the Gravity Probe B science team that they should investigate the "patch potentials" problem in the manufacturing process for the 4 ultra-precise gyroscopes.
