AI Insight
Scientists propose that extremely small black holes, potentially as light as 40 tons, could exist inside stars without destroying them, provided they are sustained by dark matter. This theoretical framework builds on Stephen Hawking's 1974 discovery of Hawking radiation, which showed that black holes emit energy and evaporate over time, with lighter black holes evaporating faster. The research suggests dark matter could stabilize these tiny black holes within stellar environments, preventing their rapid evaporation.
Why it matters
This theory could provide a new way to detect dark matter indirectly by observing anomalies in stellar behavior that might indicate the presence of internal black holes. It also expands our understanding of how black holes, dark matter, and stars might interact in previously unconsidered ways.
Understand the Science
In 1974, Stephen Hawking made a prediction that transformed our understanding of black holes. Black holes, he showed, are not truly black: They slowly lose energy through a quantum process now known as Hawking radiation. The lighter the black hole, the faster it evaporates.
