The Real Science of the EHT Black Hole (2019x14)

Air date: May 01, 2019

How do you take a picture of a black hole and what can we learn from it? Our first ever actual bona fide photo of a black hole, made by the Event Horizon Telescope and revealed to the world in a press conference on April 10th. Since then it’s got plenty of coverage, because … I mean look at it. It’s a freaking black hole. It’s black, it’s holey, it’s everything we hoped it would be. Now that the giddiness has subsided and I personally have stopped spending hours on end staring at a black spot, we can take a breath and actually look at the real science here and discuss exactly how a picture like this could be taken and what we can learn from it.
