Astrophysics from the UK and the Netherlands modeled the chaotic interaction of three black holes rotating each other. The results showed that light black holes are inclined to throw away each other into outer space, and heavy to merge with each other. Scientific work published in the magazine Physical Review D.
The problem of calculation, how the three spacebodes interacting with each other will move, such as planets, stars or black holes, are known as the task of three tel. Although initial positions and speeds can be known for such bodies, the task of three bodies does not have a general solution, that is, a system of three objects will behave chaotic, excluding certain cases.
However, in a new study, scientists broke the task into several stages. At first, the computer calculated the black holes for a short period of time, and then the result was used to calculate the trajectory in the next period of time. Since physicists considered black holes, creating significant curvature of space, the computer code took into account the theory of the relativity of Einstein. At first, scientists reviewed black holes in a mass in one mass of the Sun, and then switched to supermassive black holes, whose mass comes to a billion suns.
The simulation results showed that black holes, which are lighter than ten million suns, throw each other into the surrounding outer space using the so-called gravitational slingshot. However, heavier black holes begin to merge with each other due to the loss of kinetic energy as a result of radiation of gravitational waves.
