A new theory suggests that a so-called primordial black hole may lurk beyond Neptune in the outer solar system. - NBCNewsMACH
The researchers suggest that the primordial black hole ended up in our solar system after getting caught in the sun’s gravitational field. If the black hole does exist beyond Neptune, the researchers say it is likely surrounded by a dense halo of dark matter, a form of invisible matter that is thought to make up 27 percent of the universe. The scientists said it may be possible to detect the radiation emitted when these dark matter particles interact with other particles in the vicinity.
Konstantin Batygin, a planetary astrophysicist at the California Institute of Technology, who together with his colleague Mike Brown published a study in 2016 that, said the primordial black hole theory “is a stretch but not entirely implausible.” Bhuvnesh Jain, co-director of the Penn Center for Particle Cosmology at the University of Pennsylvania, agreed and called the new theory “very intriguing.”
