Black Holes as Dark Matter Detectors: A New Window into the Invisible Universe

A new study in Physical Review Letters proposes a groundbreaking way to detect dark matter using images from the Event Horizon Telescope (EHT). Researchers found that the dark shadows of black holes could act as natural detectors for faint signals produced by dark matter annihilation.By comparing simulated plasma emissions with these potential dark matter patterns, the team developed a morphological method to test its presence — offering a powerful new tool that could redefine how we search for the universe’s most mysterious substance.Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
