From the Ted Talk by Andrea Ghez: The hunt for a supermassive black hole
Unscramble the Blue Letters
So, to begin with, we need to understand what a black hole is so we can understand the proof of a black hole. So, what is a black hole? Well, in many ways a black hole is an incredibly simple object, because there are only three crctihrasitaces that you can describe: the mass, the spin, and the cahgre. And I'm going to only talk about the mass. So, in that ssnee, it's a very simple object. But in another sense, it's an incredibly complicated object that we need relatively eoixtc physics to describe, and in some sense represents the beakwordn of our pscihayl understanding of the universe.

So, to begin with, we need to understand what a black hole is so we can understand the proof of a black hole. So, what is a black hole? Well, in many ways a black hole is an incredibly simple object, because there are only three characteristics that you can describe: the mass, the spin, and the charge. And I'm going to only talk about the mass. So, in that sense, it's a very simple object. But in another sense, it's an incredibly complicated object that we need relatively exotic physics to describe, and in some sense represents the breakdown of our physical understanding of the universe.
