The Hunger of Supermassive Black Holes in the Universe.

Astrophysicist Joseph Simon used computer simulations to predict the masses of the largest supermassive black holes in the universe, revealing that black holes may have been much bigger on average billions of years ago than previously thought. Simon's research could help unravel the forces that shaped objects like Sagittarius A* as they grew from small black holes into the giants they are today. The findings could also shed light on the gravitational wave background, a steady flow of gravitational waves that undulate through the universe on a near-constant basis.
