Unveiling the Astonishing Growth of Supermassive Black Holes After the Big Bang

Scientists have estimated the speed limit at which black holes can be launched into the universe after merging, finding that under specific conditions, the newly formed black hole can be propelled at a speed just shy of 28,600 kilometers per second. The simulations showed that the spins and orientation of the merging black holes are crucial factors in determining the maximum velocity. The emission of gravitational energy during the collision contributes to the significant recoil, with some mass being converted into gravitational waves. The study also suggests that up to 27 percent of the mass of the black holes can be transformed into gravitational waves under certain conditions.
