In this segment, we want to spend a little more time on detecting the undetectable. John Mitchell gave a first indication of how you might detect it. And that was if a star is black, dark and it pulled over by the star police in a second. More than half the stars you see in the night sky come in at least pairs or even entire clusters.
How do supermassive black holes form? Neil deGrasse Tyson and comedian Chuck Nice come to you live to learn about the history of black holes, what’s inside them, and new discoveries with cosmologist Janna Levin and astrophysicist Jenny Greene.
