I knew somewhat about them, but a lot of things I didn't know. He said something to the effect of when a star begins to die, it starts to expand, from gas falling into it. The gas traps more heat into the star making it hotter. Once it's super hot, reactions inside the star carry away heat. Once the star loses it's heat it collapses in on itself creating a small black hole. After that, it starts to consume the gas around it, making it even larger. He said at one time there were some that were 10,000 times larger than our own sun. That' massive.
I wonder what kind of effects it would have on Earth and our solar system if a huge one developed within our galaxy or slightly outside of our galaxy. I wonder if we would be able to see it with the naked eye?

I watched a thing on the history channel tonight about the universe. They said this won't be a problem until 1 trillion a.d. Apparently at that point the sun will become a black hole and implode the entire universe creating another big bang.
