Astronomers may have detected the largest two black hole collisions ever discovered, about seven billion years ago, but the signs have just arrived. This catastrophic event provided researchers with a close-up view of the birth of one of the most elusive celestial bodies in the universe. The distant show includes two main characters: one black hole has about 66 times the mass of our sun, and the other is about 85 times the mass of our sun. The two black holes are so close together that they spin around each other several times per second, and finally collide in a violent energy explosion, bringing shock waves to the whole universe. The result is a single black hole, about 142 times the mass of our sun. < / P > < p > such a discovery may be a big one for astronomers. So far, scientists have been able to detect and indirectly observe two different sizes of black holes. Smaller species are between five and 100 times the mass of our sun. At the other end of the spectrum is a supermassive black hole, the kind of black hole at the center of a galaxy, millions and billions of times the mass of our sun. Throughout the ages, scientists have been trying to find black holes in between, so-called intermediate mass black holes, whose masses range from 100 to 1000 times that of the sun. Astronomers are convinced that such black holes must exist, but they have not found any direct evidence of their existence. Salvatore Vitale, an assistant professor of gravitational waves at MIT’s LIGO laboratory, said: ‘it has always been a puzzling question that people can’t find any intermediate black holes. They are black holes with dozens of solar masses and millions of solar masses. It’s always a bit puzzling that people can’t find anything between them. &The discovery is described in detail today in the Journal of Physical Review and Astrophysics journal bulletin. We may have discovered the birth of a medium mass black hole for the first time. One theory about how supermassive black holes get so big is that smaller black holes merge again and again, merging into them to become huge. But if so, there must be an intermediate black hole somewhere in the universe. That’s why astronomers have been looking for these extensively, because they will help solve this problem. To detect this dance of black holes, scientists measured the tiny shockwaves produced by the merger. When incredibly large objects like black holes merge, they distort space and time, creating ripples in the structure of the universe, shooting out of events at the speed of light. These ripples, called gravitational waves, are huge when they are created, but they are very weak and very difficult to detect when they reach our planet. < / P > < p > thanks to observatories in the United States and Italy, scientists are already very good at detecting these tiny gravitational waves. These are called LIGO and Virgo stations and are designed to detect these infinite wavelets from cataclysm merging. Since LIGO first detected gravitational waves in 2015, the Observatory has accumulated impressive results, detecting about 67 black holes, neutron stars and black hole and neutron star mergers. Today’s announcement is also the farthest merger between LIGO and Virgo, which will take us 7 billion years. This event, gw190521, was detected on May 21, 2019, and it is very weak and easy to miss. LIGO and Virgo’s detectors received only four wavelets from the merging, which lasted only a tenth of a second. In processing the data, the scientists used four different algorithms to look for these fluctuations, ultimately allowing them to determine precisely the quality of the merger and how much energy was released.
