What is it with Black Holes?

What is it with black holes that intrigues me so much? (the picture to the left is not a black hole, but nice anyways) Or is it simply the fact that it's too easy to intrigue me? I don't know. I do remember my mom used to tell me how, when I was 4/5, and we lived on a farm, I used to walk all the way towards the end of the path leading to our house. There was a fence there. But after I had figured out how to open that fence, I would simply walk into the woods nearby. And I would simply not stop walking, which resulted in many scared moments for my mom. Well, sorry! But anyway, I loved to discover then, and I do now, so what is it with black holes that intrigues me so much? Well, anyhow, they say they discovered a whole bunch of new ones.

PS: 'Black holes cannot be seen directly, because they trap light and anything else that gets too close. But astronomers infer their presence by noting the behavior of material nearby: gas is superheated and accelerated to a significant fraction of light-speed just before it is consumed.'
