The statement of scientists from the LIGO collaboration about the discovery of gravitational waves raised a lot of questions.
It is known that the burst of gamma rays was caused by the fact that two black holes, "weighing" about 30 times the Sun, rotated in a spiral around each other, and then merged into one.
According to scientists, no one expected that the merger of black holes would be accompanied by such a bright burst. Isolated black holes are unable to generate such a burst of radiation, scientists are sure.
For several days, experts puzzled over the question of what could have generated such powerful gamma radiation.
Avi Loeb of Harvard University suggested that such a reaction could have happened if two black holes were inside a very massive star.
After merging black holes, the star collapsed and emitted intense gamma rays.
According to scientists, when the star has exhausted its nuclear fuel, its core begins to collapse, forming a black hole. In this case, when the star rotates very quickly, the centrifugal force will stretch the collapsing core, forming it into a "dumbbell", which will eventually split into two cores. They, in turn, form as a result two black holes inside the star.
It should be noted that this is still only a theory that requires a long study and confirmation.
