Merge two holes
In the near future, we are likely to see a wonderful sight — the merging of two black holes, which are supermassive black holes and
located in the center of the quasar PG 1302-102, located 3.5 billion light-years from Earth. According to preliminary calculations, an explosion of 100 million supernovae should be carried out with a one-time explosion power.
These are the black holes most closely spaced to each other, revolving around a common center of mass among those known to us today. The period of mutual circulation is 5 years and they have already crossed one another with the accretion disks. More precisely, a small, but already supermassive black hole (small against the background of a supermassive black hole in the center of the quasar) fell into the accretion disk of the central monster and is actively absorbing it.
The quasar has a variable brightness and color, and with a frequency of 5 years. This attracted the attention of scientists, and this is precisely what indicated that the system most likely contains two black holes rotating around each other with a similar period.A smaller black hole flies around a more massive one with a considerable speed, 7% of the light one, from which it very noticeably changes the color of the radiation due to the so-called violet shift. Relativistic effects at such speeds also make themselves felt, which is confirmed by twenty-year observations of the behavior of a quasar.
Black holes are still relatively far from each other by event horizons. The distance between them is about 290 billion kilometers, as from the Sun to the Oort cloud. At such speeds and masses, it is difficult to predict what will happen next, how the merger will take place in detail, and what effects will be observed, but scientists will almost certainly be sure that it will bubble up.
