The above statement points to an obvious solution of the "dark matter" mystery. Since the work of Fritz Zwicky in the 1930's and Vera Rubin in the 1950's, astronomers have suspected that galaxies contain hidden mass. Something that is dark but has gravitational attraction is a perfect description of Black Holes, billions of them populating the galactic halo. Yet physicists tend to ignore Black Holes as "dark matter" candidates, preferring to search for exotic particles like neutralinos and WIMPS. None of these speculated particles has ever been found. Scientists from a particle physics background would prefer if the answer was in their exotic particles.
The August 23 issue of NEW SCIENTIST contains an interesting article:Is the Universe Made of Holes?
"MOST of the matter in the universe gives out no light, or at least so little that it is currently undetectable. Yet we know it is out there because its gravity keeps stars and galaxies in their orbits. Pretty much everyone thinks that this so-called dark matter is made of hitherto undiscovered subatomic particles. Physicists are hopeful they will find a candidate in high-speed collisions at the Large Hadron Collider at CERN, near Geneva, Switzerland.
"But could we have got dark matter all wrong? Mike Hawkins thinks so. He believes that rather than particles, what we call dark matter is actually legions of black holes created shortly after the big bang."
Because the speed of light was once much faster, primordial singularities could have formed with a variety of masses. Mathematics predicts
that 23.87% of mass will have collapsed into singularities, surrounding the galaxies in haloes of dark mass. Some of these primordial Black Holes could exist in our solar system, even within Earth's core. The solution to this dark mystery may be beneath our feet.
