Dark matter could keep tiny black holes alive inside stars

Dark matter, the unseen substance that makes up most of the universe’s matter, could play a more dramatic role than previously thought, a new study suggests.

According to researchers, heavy dark matter particles trapped inside a dense star could accumulate at its core, collapse into a tiny black hole roughly the mass of a loaded semi-truck and gradually transform the entire star into a black hole.

Such black holes would evaporate rapidly if left on their own, researchers said.
