What you don't see in the video is me interviewing the study's author (he was in a hotel room and the sound quality wasn't great) but I was delighted he took the time to talk to me. I also interviewed my General Relativity prof from the University of Sydney. He provided some much-needed perspective so I could make this video. It started out as a video about a discovery but I thought it was more valuable to express the state of the field. I hope I've captured that in this video. I spent a few sleep-deprived nights trying to get this out around the launch of the study but I still missed it by a couple of days.

Also important to note: a couple of the animations here are from NASA (and they're great) but most of them are custom animations by a new animator I've been working with. I think they're amazing. They are also time-consuming and expensive, so I wouldn't be able to make videos like this without your support. Thank you!

Spinning Black Holes

A pulsing black hole in the centre of a distant galaxy sheds light on black hole and galaxy formation. How fast are black holes rotating and how does that rotation change over its life-span?

Amazing! Just... wow. Thank you... I learned a lot. (And the animation is great, so kudos!)

Due to conservation of angular momentum, it seems like if you build a bunch of black holes inside a galaxy from random stuff in that galaxy, and then mush them together you would end up with the same spin compared to building a single black hole from the same original stuff. Is the thought that one process picks up stuff from outside the given galaxy or perhaps one process selects different stuff from inside the galaxy?

Another well done piece Mr. Muller. An intriguing and accessible explanation.
