Astrophysicists Ask a Simple Question -- What if Dark Matter is Just Black Holes?

Astrophysicists Ask a Simple Question -- What if Dark Matter is Just Black Holes?

Proposing an alternative model for how the universe came to be, a team of astrophysicists suggests that all black holes—from those as tiny as a pin head to those covering billions of miles—were created instantly after the Big Bang and account for all dark matter. That’s the implication of a study by astrophysicists at the University of Miami, Yale University, and the European Space Agency that suggests that black holes have existed since the beginning of the universe ¬¬and that these primordial black holes could be as-of-yet unexplained dark matter. Dark matter — which has never been directly observed — is thought to constitute the majority of matter in the universe and act as the unseen scaffolding upon which galaxies form and develop. Physicists have spent years looking at a variety of dark matter candidates, including hypothetical particles such as sterile neutrinos, Weakly Interacting Massive Particles (WIMPS), and axions. If this new black hole hypothesis is proven true with data collected from the James Webb Space Telescope, the discovery may transform scientific understanding of the origins and nature of two cosmic mysteries: dark matter and black holes.

Do you know if the value for the mass of the kinetic energy associated with all the rotating bodies in the galaxies has been accounted for. I would think that would be difficult to calculate. Also, the interstellar and stellar nursery dust.
I believe that some actual observations that demonstrate the existence of dark matter should have been found by now. Time to start looking in other directions.

James:

Thanks for the comments.

I agree with your observations, especially as related to rotating bodies.

I have long believed that the mystery of dark matter will eventually be solved not through the discovery of new invisible particles, but through a better understanding of the relationships between gravity, centripetal force, and fast (and very fast) rotating bodies, especially as related to the cumulative effect of when most of the rotating bodies are aligned in the same plane.

This is just me thinking out loud, but a number of observations lead me in this direction -- one being the apparent correlation of dark matter "content" in galaxies as compared to the luminosity measurements of spiral galaxies when viewed edge-on vs. face-on and at all angles in between. I believe there is a relationship that we just don't fully understand.

My thought -- Fast-rotating gravity in a spiral galaxy gets flattened and redistributed to the edges of the of the flat-rotating plane and away from the poles. In that case, the total amount of gravity in a given galaxy wouldn't necessarily change, but the axial distribution of gravity would differ based on what part of the galaxy is being observed and measured. This could be tested by measuring the gravitational lensing of edge-on spiral galaxies at the poles as compared to the left and right sides of the galaxy. If my ideas are right, the lensing should be substantially greater at the right and left sides of the spiral galaxy than at the poles.

I am not aware of any work going on in this area, but it seems to me that it should be easily testable and could potentially be a fruitful area of research.

I'm confident that eventually we'll get there and the mystery of Dark Matter will be solved -- Maybe even in my lifetime. But I agree with you that we need to start looking in new directions.

Looking for elusive, invisible particles is not simply getting us anywhere.

Thanks,
