Dark Matter Might Explain How Colossal Black Holes Merge

For decades, the merging process of supermassive black holes has puzzled astrophysicists, but recent findings suggest that dark matter may hold the key to understanding this cosmic phenomenon.

When two galaxies collide, their central supermassive black holes typically enter a dance of gravitational interaction, orbiting one another. Over millions of years, this interaction with surrounding matter leads to the expulsion of material and generates friction. This friction serves to gradually decelerate the black holes, causing them to spiral inward toward each other.

As these black holes continue to approach…
