For decades, scientists have recognized that large galaxies in our Universe have supermassive black holes (SMBHs) at their centers. These behemoths, which are millions to billions of times the mass of our Sun, play a vital role in star formation and the long-term evolution of galaxies. According to a recent study based on observations performed using NASA's Chandra X-ray Observatory, it appears that most dwarf galaxies may buck this trend. This stands in stark contrast to their theory that nearly every galaxy has a massive black hole within its core.
