Both black holes and dark matter represent two of the biggest mysteries in astrophysics. Researchers began to find clues of the existence of the two structures without even observing them directly, proving the beauty of science once again. But could there be a link between black holes and dark matter?
While being in charge of a giant 8.2-metre-wide telescope, scientists from the University of California, Los Angeles, and the Kavli Institute for the Physics and Mathematics of the Universe in Japan began to search for primordial black holes within the depths of the Cosmos. Unlike usual black holes, the primordial ones are only hypothetical structures that emerged shortly after the Big Bang.
Intergalactic primordial black hole?
As the scientists hope to find, a primordial black hole could be floating between the Milky Way and another galaxy. It could sound redundant for some people, but there’s a good chance that discovering such an object will complete the scientists’ knowledge of topics like the nature of dark matter, the distribution of heavy elements across space, and so on.
The outcome could also answer one of the most important questions for the last years of astrophysics: is our Universe part of a Multiverse or not? If the answer is yes, it means that there could be countless other universes more or less similar to our own. There are several scientific theories that describe parallel universes, and some of them imply the idea that there could be a copy of each one of us in each of those universes.
Yakov Borisovich Zel’dovich and Igor Dmitriyevich Novikov were the first scientists to propose the existence of primordial black holes way back in 1966. Stephen Hawking began to study the origins of such black holes in 1971.
The new research was published in Physical Review Letters.
