Join Hugh Ross in this breaking News of the Day episode of Stars, Cells, and God. Hugh describes a discovery that may resolve a long-standing mystery about dark matter.
Primordial Black Holes Resolve Dark Matter Mystery?- Dark matter is matter that doesn’t interact with light or interacts at an extremely weak level.
- The quantity of dark matter that exists and its locations in the universe are not mysteries.
- Dark matter’s composition is a mystery that has stymied astronomers and physicists for 5 decades.
- Leading candidates for dark matter’s composition are axions and sterile neutrinos, but neither of these particles has been detected.
- Physicists Elba Alonso-Monsalve and David Kaiser propose that primordial black holes (PBHs) could make up all or a large fraction of dark matter if they formed previous to a tenth of a quadrillionth of a second after the cosmic creation event.
- These PBHs would take two forms: atom-sized bodies with masses equal to that Deimos and Phobos; bodies a ten thousandth the diameter of a proton with masses equal to a ton, with only the first form possibly existing to the present time.
- Observable tests for these PBHs include the degree to which they would 1) shift the balance between protons and neutrons, 2) cause ripples in the cosmic spacetime fabric, and 3) affect the amount of helium produced during the universe’s first 3 minutes.
