Black holes are also

American astronomers say an unusual phenomenon in the universe has been discovered, when a giant black hole is removed from its galaxy.

According to experts, they found evidence that this black hole is being expelled from the CID-42 galaxy at millions of kilometers per hour.

'The fact that a supermassive black hole has millions of times the mass of the Sun is unbelievably hard to believe, is about to be thrown out of the galaxy at such a tremendous speed,' Space.com quoted the leader Francesca Civano of the Harvard-Smithsonian Center for Astrophysics.

Observations with the Chandra Optical Observatory of the US Aeronautics and Space Administration (NASA) show that the black hole collided and merged with another black hole. The clash process created an extremely powerful radioactive wave, pulling that black hole out of the center of the galaxy.

'New data supporting the idea of ​​gravitational waves - ripples in the spatial structure predicted by genius Albert Einstein but have never been discovered in reality - can create a tremendous force' , Civano presented in the report at Chandra Center in Cambridge, Massachusetts (USA).

The findings mean the fact that there are black holes roaming in inter-galactic space, although experts have not observed them.
