Episode 2: Looking at black holes with Kelly Weinersmith

a series of photos of Stars orbiting the black hole, 4 million times heavier than the sun, at the center of our galaxy. click to see the animation.

In episode 2 we decided to try to convince Kelly Weinersmith that black holes totally exist and that if you look out in the sky that you can see them (the animation to the right was poached from UCLA ). Jocelyn gets thrown into a black hole, Ben tortures some children, and Dave proposes a title for a fantastic scifi blacksploitation movie.

Guest: Kelly Weinersmith

Physicists: Jocelyn Read, Dave Tsang

 

Intro Music: Ted Leo and the Pharmacists 

Exit Music: John Vanderslice

  1. A friend of mine wants to know whether a theory of quantum gravity will get rid of the singularities in black holes. Ummmmm …. will it do so? Do you suppose you guys could do a whole show on quantum gravity?

    • part of the ambitions of a quantum gravity theory involves getting rid of singularities in the middle of black holes. It’s a super tricky business. I even wrote a paper on one type of thing about that last year.

      a whole show on quantum gravity? … to be honest, i doubt it. I want to to try to keep the focus on physical theories which have been verified in experiment or observation. also, there are a great many different “theories” of quantum gravity. they’re all either too hairy and difficult to make much sense of, or provide undesired consequences. but there are lots of them.

      but time will surely tell.
