Static holes defy theory
Giant black holes create mystery by not flying out of galaxies.
Theorists predicted it would be one of the most dramatic events in the Universe: two black holes merging in a distant galaxy and then flying out of that galaxy, releasing the energy of tens of millions of Suns.

The prediction of the escape of the SuperMassive Black Holes from galaxies was done by Silchenko, O. K.; Lipunov, V. M. 22 year ago in the paper 'Nomadic' nuclei of galaxies (Astrophysics and Space Science, vol. 117, no. 2, Dec. 1985, p. 293-301,

Hello!
There is no mistery here. Collisions of 2 black holes are rare events in Universe. The proofs that such events did happen in the past are the ringh-shaped galaxies.
