Oddziaływania czarnych dziur

Abstract

The final stage of an unrestrained gravitational collapse is a single object known as a black hole. Do black holes always have the same universal form? Although the uniqueness theorem provides a positive answer to this question, every theorem is only as strong as its assumptions. For many years physicists were unable to exclude the existence of stationary configurations of two black holes that could form together a more complex object. Currently, we know the solution to this problem.
