A black hole as light as 40 tons can exist inside a star if dark matter helps

Researchers propose that a black hole with a mass as small as 40 metric tons could exist inside a star if dark matter plays a role in its formation and sustenance. This concept involves 'endoparasitic black holes' (EBHs) that form within neutron stars or white dwarfs by capturing dark matter particles. These black holes can grow by accreting both baryonic matter and dark matter, potentially overcoming Hawking radiation which causes smaller black holes to evaporate. The study suggests that under certain conditions, such a black hole could maintain stability by balancing mass gain from accretion against mass loss via Hawking radiation.

Bias read (Center): The article presents scientific research without overt ideological framing. It discusses theoretical physics concepts and their implications without taking a political stance. The focus is on explaining a scientific hypothesis rather than promoting any particular ideology or agenda.
