Show Notes

In today's episode, Tony suggests a black hole as being the perfect pet while George wonders what an accretion disk is and why she'd want to smear the neighbours on it. Vital questions are asked like:

  • Will our black hole suck in our neighbours?

  • Does a black hole clean up after itself?

  • And, most importantly, are the goats on the mountain upside down?!

Tony's notes for this episode are as follows: Pōwehi, a Hawai'ian word meaning "the adorned fathomless dark creation" Star sign: Pōwehi is a Virgo! (Got it wrong but we don't know what that is anyway) Erratum: I got mixed up with size ratios. M87 black hole is not 30-40x the apparent size of our supermassive black hole (not sure where I got that from :P), it's about the same apparent size in the night sky when we look at it from Earth - whilst it is about 2000x bigger it is also about 2000x further away. However, the actual size of it's event horizon is about 3x the orbit of Pluto. The accretion disk (orange bit) is about 0.4 light years, so its an absurdly big object.

**Some recent Blackhole videos from some channels I follow pretty religiously.** Anton Petrov, Dr Becky and Scott Manley are excellent for translating recent scientific papers into something understandable and explaining recent space related events and concepts. Dr. Becky's video about the 5 Types of Black Hole (we missed intermediate ones!) and I kinda assume quasars are just big supermassive ones, but they are very far away so it is hard to tell!! https://www.youtube.com/watch?v=CeKLKyzsJ2g Anton Petrov's video on the M87 black hole (Pōwehi) nicely shows off the size comparisons. https://www.youtube.com/watch?v=y2BFxfC8Ehk Scott Manley's amazing 360 degree VR video (you can move it around!) that shows what it looks like as you fall into a black hole. He does great space videos, covers a lot of recent space exploration news (his breakdowns of launch failure videos are my go to whenever "we are not going to space today"). https://www.youtube.com/watch?v=JDNZBT_GeqU These two are also fantastic: Kurzgesagt – In a Nutshell's Ultimate Guide to Black Holes. Kurzgesagt's videos are cute, beautiful and spectacularly well put together.https://www.youtube.com/watch?v=QqsLTNkzvaY PBS Space Time This channel was recommended to me by a friend who works at the Arcetri Observatory in Florence. They do some deeper dives into a range of topics we frankly brutalised. I always learn something new watching these, they are masters of making some of the most complex concepts in physics understandable. They have lots of great ones, too many to list here. Here are some tricks you can do with a rotating black hole... https://www.youtube.com/watch?v=UjgGdGzDFiM
