How Big Can Black Holes Grow?

The video explores the nature and growth of black holes, explaining how they accumulate mass through accretion and the limits imposed by gravitational forces. It introduces the concept of the innermost stable circular orbit (ISCO) and its role in black hole growth. Theoretical mass limits for black holes are discussed, along with the potential for growth through mergers. The video concludes with the idea that massive black holes can only grow by colliding with others.
