Exploring Black Holes in the Universe

The video explores various black holes, starting with smaller ones like the 100,000-solar-mass black hole in J1601, and moving to larger ones such as the 66 billion-solar-mass black hole in TON 618. It covers black holes in our galaxy and nearby galaxies, including the Milky Way's 4 million-solar-mass black hole and the Andromeda galaxy's black hole. The video also highlights supermassive black holes like those in NGC 7727 and Cygnus A, and concludes with the largest known black holes, including M87 and TON 618.
