A new study published in the Astrophysical Letters by Vanderbilt University in the United States suggests that they have found a promising new way to help future scientists explain potential populations of stars and test the theory of the formation of all colliding black holes throughout the history of the universe. Since the breakthrough in gravitational wave astronomy in 2015, scientists have been able to detect more than a dozen pairs of very close-standing double black holes by colliding with each other by gravity. But scientists are still debating how many of these black holes are produced by stars.
Scientists have now provided a theoretical explanation for the formation and existence of double black holes in the universe, but the origin of the stars remains a mystery as their predecessors, the researchers said.
Through research, the researchers found that there was a basic constraint in the formation of these black holes, which we used to calculate the proportion of stars that have been able to collide into black holes since the birth of the universe.
Using Einstein’s general theory of relativity, the researchers combined events recorded by the Laser Interference Gravitational Wave Observatory (LIGO) to take stock of space-time resources at different points in time.
They speculated on the constraints of each step in the formation of the double black hole: the number of stars available in the universe, the transition of each star to a single black hole, and the gravitational waves that eventually formed these collisions were detected.
Based on current observations, researchers have found that 14 percent of the universe’s large-mass stars are destined to collide in the form of black holes. These additional constraints will help researchers track the history of black holes and explore the origin of stars.
