How Many Black Holes Exist in the Milky Way
🎧 "100 million. That's the estimated number of black holes hiding in our galaxy. We've found less than 100."The Milky Way likely contains around 100 million stellar-mass black holes—remnants of collapsed giant stars [citation:1][citation:5][citation:8]. Yet, fewer than two dozen are confirmed [citation:1]. Most are invisible, emitting no light. New techniques like astrometry and microlensing are finally revealing this hidden population [citation:7][citation:8]. Beyond stellar-mass, scientists predict our galaxy also hosts about 130 intermediate-mass black holes (IMBs) from the universe's first stars [citation:3]. Plus, the supermassive beast at our center, Sagittarius A*, weighing 4 million Suns [citation:4][citation:6]. Join us as we explore the invisible giants around us.
