In our universe, galaxies collide with other galaxies and, in the process, the supermassive black holes at the core of the galaxes will form a pair.
“Penil and his collaborators studied five blazars. He found that PG 1553+113, which Penil described as the most well-known blazar in the context of periodicity behavior, exhibited evidence of a 2.2 quasi-periodic oscillation in radio, optical, ultraviolet (UV) and gamma-ray bands.”
