The Singularity of a Black Hole

Hawking famously changed his mind on this. So first he thought you couldn't recover anything from a black hole. And then now it's not so clear, because we don't really understand what happens to the properties of things that fall into black hole. The tricky part with the event horizon is actually the singularity that's encased in it,. And that's the real singularity. One just thinks about it as an asemtotic place. Let's get back to dark matter. One of the giant contributions that you have made is direct collapse black holes, which we've talked about. Another one is in the mapping and measuring of dark matter.
