The universe keeps producing surprises, and black holes are right at the center of it. The largest stars ever discovered don’t fit the usual story of how stars die. A new study reportedly suggests that these extreme objects may not have formed in a single collapse at all. Instead, they may move inside dense star clusters, where gravity constantly pulls objects into closer contact. Scientists analyzing gravitational-wave data from LIGO-Virgo-KAGRA believe that repeated mergers may be the real engine behind these giants, ScienceDaily reports. This is a dirty, violent idea. Black holes are colliding again and again, slowly creating something much larger than a single star. And the more the data is studied, the more this pattern emerges.<\/p>\n Globular clusters can be considered some of the densest parts of space. In this location, hundreds of thousands of stars are concentrated in a small sphere, held together by gravity. An example of such a globular cluster is the star cluster M80, which is estimated to be 28,000 light years from Earth, according to Cardiff University. The globular cluster region is highly unstable and dynamic.In such an environment, black holes cannot remain separated for long. Black holes move around, approach each other and merge. Scientists believe such an environment could facilitate black hole mergers through natural processes. The process itself is not smooth; This occurs through gravitational interactions over millions of years. The study group analyzed data on 153 black hole mergers that were recorded in the GWTC4 catalogue. This database contains observations of gravitational waves that are produced by collisions of celestial bodies such as black holes.What scientists found was a clear division between the two types of black holes. One group appeared to be low in mass, moving slowly and quite methodically. These are thought to come from normal stellar collapse, where a massive star reaches the end of its life and forms a black hole.The second group looked very different. These black holes were heavy and rotated at high speed. Their spin directions also seemed random rather than aligned. According to researchers, this is an important clue. This may indicate that these objects did not form in a single event, but rather through multiple mergers inside dense star clusters.<\/p>\nHow black holes form, merge and grow inside dense globular clusters
