"From the Ted Talk by Andrea Ghez: The hunt for a supermassive black hole"

Unscramble the Blue Letters

So, I watend to say a few words about what an ordinary black hole is, as if there could be such a thing as an ordinary baclk hole. An ordinary black hole is thought to be the end state of a really massive star's life. So, if a star starts its life off with much more mass than the mass of the Sun, it's going to end its life by eixpolndg and leaving behind these beautiful supernova remnants that we see here. And inside that snpvuroea remnant is going to be a little black hole that has a mass rguolhy three times the mass of the Sun. On an astronomical scale that's a very salml black hole.

Original Text

So, I wanted to say a few words about what an ordinary black hole is, as if there could be such a thing as an ordinary black hole. An ordinary black hole is thought to be the end state of a really massive star's life. So, if a star starts its life off with much more mass than the mass of the Sun, it's going to end its life by exploding and leaving behind these beautiful supernova remnants that we see here. And inside that supernova remnant is going to be a little black hole that has a mass roughly three times the mass of the Sun. On an astronomical scale that's a very small black hole.
