- brothrock 3y agoIf anyone is interested in the history and an accessible, but deep understanding of black holes I highly recommend Kip Thorne’s book “Black Holes and Time Warps” (1994). The first half of this article follows a summary of that book closely.
- ViktorRay 3y agoKip Thorne was also in charge of the science of Interstellar (2014 movie). He even wrote a book called The Science of Interstellar. Also he won the Nobel Prize in Physics. Very smart man!
- MathMonkeyMan 3y agoHe also coauthored one of the classic textbooks on general relativity, [Gravitation][1]. [1]: https://en.wikipedia.org/wiki/Gravitation_(book) https://en.wikipedia.org/wiki/Gravitation_(book)
- defrost 3y agoIf anyone's keen to go deeper and catch up on the latest thought on such things it's not to late to slide into the Seventeenth Marcel Grossmann Meeting, Pescara, Italy (7-12 July 2024). https://indico.icranet.org/event/8/ https://indico.icranet.org/event/8/ Sergiu Klainerman: The nonlinear stability of slowly rotating Kerr black holes The full proof of the nonlinear stability of Kerr consists of five papers, three written in collaboration with Jeremie Szeftel, one in collaboration with Elena and Jeremie Szeftel and another supporting paper authored by Dawei Shen. In my lecture I will describe the main architecture of the proof as well as some of the most important consequences.
- xqcgrek2 3y agoSeems like a puff piece with nothing particular new or something you wouldn't find on wikipedia
- waldothedog 3y agoDon’t think “puff piece” is the phrase you’re after here. Also, the novelty of the information might be relative to the source/reader?
- commakozzi 3y agoAgreed. the information in the article appears to be new to someone who has literally never heard about black holes... a 5 year old perhaps.

- whateveracct 3y agodon't you know HNers are astrophysics experts? they always list their theories about the cutting edge in comment threads lmao

- renewiltord 3y agoIt’s the New Yorker. The audience is not universally familiar with the topic.
- tbrownaw 3y agoSure, but this doesn't actually talk about things like them having shadows around them, or evaporating, or having a "photon sphere" where light orbits, or how you'll never see anything actually fall in because of the time dilation.
- ilrwbwrkhv 3y agoOur universe lives inside the singularity of a black hole. Each black hole has another universe inside it. The reason our universe is expanding is because our parent black hole is undergoing hawking radiation which stretches the fabric of our universe.
- radarsat1 3y agoBut there are black holes in our universe. Can black holes be inside black holes?
- hn72774 3y agoWouldn't that just be our view of another universe? And some universe out there sees our universe as a black hole? It's hard to imagine a fixed limit on how far deep this pattern can go. The multiverse theory suggests that all possibilities exist at the same time in an infinite number of universes. Can universes have circular references to other universes? A is a black hole in B, B is a black hole in C, and C is a black hole in A? I have no idea about any of this but it's fun to think about.
- Euphorbium 3y agoIt is black holes all the way down.
- MaxikCZ 3y agoI think so too on everything but why is our universe stretching. If our universe started at a point, wouldnt that corelate of formation of blackhole - also at a point? Wouldnt stretching our universe mean the blackhole is actually growing? A lot of matter feeding a blackhole shortly after it forms would explain our rapid inflation. But at the same time, once our universe stretches so fast that each photon is receding from all other photons faster than speed of light (completely isolate it from the rest of the universe), it fits into my analogy of escaping our universe and it being emited (trough hawking radiation) from the black hole. In that case growing our universe to infinity (and asymptotically reaching zero density) would fit into blackhole evaporating, so I just dont know.

- lostmsu 3y agoUnless you want to read a long form novel of low to moderate quality, you are probably better off reading https://en.wikipedia.org/wiki/Black_hole https://en.wikipedia.org/wiki/Black_hole . Even the pictures there are better.
