Dark matter could keep tiny black holes alive inside stars: study
Such black holes, each roughly the mass of a loaded semi-truck, would evaporate rapidly if left on their own, say the researchers
Dark matter, a mysterious substance that accounts for most of the universe's matter, may have a more significant impact than previously believed, according to a new study. Researchers H.A. Adarsha, Chandrachur Chakraborty, and Sudip Bhattacharyya from the Manipal Centre for Natural Sciences and the Tata Institute of Fundamental Research propose that heavy dark matter particles trapped within a dense star could accumulate at its core, potentially transforming the entire star into a black hole.
The study, published in the latest issue of Physical Review D, explores the potential of ultra-heavy dark matter particles to keep such tiny black holes alive inside dense stars, such as millisecond pulsars and white dwarfs. These ancient stars, having exhausted their nuclear fuel, serve as unique laboratories for testing ultra-heavy dark matter, which is challenging to study on Earth.
