Black holes are like cosmic vacuum cleaners, they suck everything in. But not all black holes are the same. Some have more 'hair' than others, which means they look different from the outside. This hair helps scientists know what’s inside the black hole.
Examples
- A black hole with more 'hair' is like a vacuum cleaner that's both spinning and charged, it looks different from another one that’s just spinning.
