Hey, can you explain everything that is to be known about black holes?
Everything? I dunno, that’s a lot of stuff.
Well, not really. Although we know quite a bit about black holes, we really know only about the stuff around them. As for the black hole itself, its a bit more difficult to learn about things that almost don’t exist. Black holes are a very large mass that has collapsed on itself so hard that it’s pulled the covers of space-time over itself and disappeared. All we can see is the gravity field that it left behind.
However, what I can do is direct you to some really good resources that can explain singularities.
NASA - of course - has a good page about the basics of singularities. It’s labeled ‘for kids’, but I’ve always turned to pages like this when I’m learning the basics of a topic.
A more in-depth - and therefore slightly more difficult to understand - write-up about singularities can be found on National Geographic’s site.
If you like that, don’t be afraid to go to Stephen Hawking’s site, and read one of his writings on black holes. Some of his ideas are unproven, but are fascinating and could easily be true. He’s able to take complicated sciency-stuff and write quite clear explanations for it. Think about reading his book on the whole universe. It’s surprisingly understandable to everyone.
But, if you’ve only got a few minutes, you can take in a couple of animated lectures by Hawking. They’re from the BBC, so you know they’re good.
