What Is the Age of the Black Hole?

We can see these black holes because they're actually really shiny, or at least tha what's around em is really shiny. In fact, super shiny red, like it's brightot in the whole galaxy. They are crazy shiny. These things are called quasars. And when they were first discovered, people didn't really understand they didn't believe them tey tho there must be something wrong,. Because you're looking at something superdistent and yet per bright, which means that at its source it must be ridiculously bright.
