A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape from it. This occurs when a massive star collapses under its own gravity at the end of its life cycle, leading to the formation of a singularity—a point of infinite density—surrounded by the event horizon, which is the boundary beyond which nothing can return once crossed. Black holes can vary in size, ranging from stellar black holes, formed from individual stars, to supermassive black holes, found at the centers of galaxies and containing millions to billions of times the mass of the Sun. The study of black holes involves theories of general relativity and quantum mechanics, and they play a key role in our understanding of the universe’s evolution, structure, and the nature of space and time.
A groundbreaking discovery has been made in the distant galaxy OJ 287, revealing the presence of two black holes. This finding, confirmed by NASA's Transiting Exoplanet Survey Satellite (TESS), sheds…
