When you hear the term 'black hole', you probably imagine a terrifying cosmic vacuum swallowing everything in sight. But black holes are far more fascinating and dramatic than science fiction suggests. In this episode of History of Simple Things, we slow things down and explore what black holes really are: how they form, why gravity becomes unstoppable, what an event horizon and singularity mean, and how scientists study objects that don’t emit light. A simple and clear explanation of one of the most mysterious phenomena in the universe is presented here, from dying stars to warped space and time. Whether you're new to astronomy or just curious about the cosmos, this video will help you understand black holes without the hype -- just the wonder.
