The video tutorial explains black holes, areas in space with strong gravity where even light cannot escape. It covers their formation from dense matter and stars, types like stellar-mass and supermassive black holes, and their structure, including the event horizon and singularity. The video also discusses how astronomers detect black holes by observing their effects on surrounding space. It concludes with reflective questions about the future of black holes in the universe.
