Astronomers may have heard, for the first time, the sound of dark matter 'building blocks' colliding—black holes lighter than the Sun. Such objects aren't born from stars; if confirmed, this would flip our understanding of the universe's makeup.
🎯 A black hole with half the Sun's mass has a radius of about 1.5 kilometers—such an object could fit into a small town center, but would pull in everything around it with monstrous force.
