Multiverse Theory
A strange new theory suggests that tiny primordial-black holes – those that formed at the very beginning of our universe – may form dark matter and, bizarrely, contain small collapsing universes.
This is a bizarre idea, but if Motherboard reports, it tackles several of the most important mysteries of the cosmos simultaneously, albeit in a speculative way. But most controversial about the research, which was published in the journal Physical overview letters it suggests that our whole universe may look just like another little black hole bubble to an outside observer.
Trained guesswork
Scientists have long struggled to identify dark matter, the invisible things that are theorized to make up the bulk of the universe’s mass, and that cluster galaxies together. Several physicists have suggested that it consists of particles that have not yet been detected, that it is formed by boiling plasma and even that it does not exist at all. However, according to this study, all the dark matter that scientists suspect is somewhere in the universe could make up with these bizarre primordial black holes.
“We still do not know what dark matter consists of, but since black holes are known to exist, it is natural to ask whether dark matter can be composed of black holes that can form before the stars and galaxies formed, “Astrophysicist and lead author Alexander Kusenko, University of California, Los Angeles, tells Motherboard.
Antique bubbles
Those over-black holes, Motherboard reports, would have bubbled up during the earliest days of our universe, when it was extremely dense and in a state of constant current.
And within them, Kusenko says, can be small universes, without matter, that began and could not form as our own universe expanded rapidly.
