Supermassive Black Holes: A Surprising New Theory Challenges Conventional Wisdom

Supermassive Black Holes: A Surprising New Theory Scientists are re-examining how supermassive black holes form. A recent Lex Fridman Podcast featuring theoretical physicist Janna Levin revealed a groundbreaking theory. Levin suggests that these immense cosmic objects may not always form from the collapse of dying stars, as previously thought. Instead, some supermassive black holes may form directly from primordial matter in the very early universe. "It's only about 1% of stars that will end their lives in a death state that is a black hole," Levin stated, highlighting the rarity of the traditional formation method. This discovery challenges conventional understanding. Levin further explained that due to their immense size, supermassive black holes have surprisingly low density, potentially as low as air. This makes it easier for them to form directly from primordial material. The implications are significant for our understanding of galaxy formation. The video explores the question of which came first: the black hole or the galaxy? Levin suggests a deep relationship, with black holes potentially shaping the growth of galaxies through powerful jets that expel material. This new theory presents exciting possibilities for future research and a deeper understanding of the universe's origins.
