Black Holes

The video explains black holes, regions in space with gravity so strong that even light cannot escape. It describes how black holes form from dense matter, like a squished sponge, and details two types: stellar mass black holes from collapsing stars and supermassive black holes at galaxy centers. The video covers the structure of black holes, including the event horizon and singularity, and discusses their effects on nearby objects. It concludes with how astronomers detect black holes and ponders their potential to consume the universe.
