#tw bkl singularity

[augmentedchordsofficial]

Howdy my dearest August! I know you haven't been doing the best lately, but I'm here for you always and I love ya muchly!! <3 /p

You're a smart, talented, and absolutely wonderful person who I am glad to call a friend! You can use the rest of this ask to yap about something you like, but ofc no pressure! Take a relaxing break, and I'll be here to listen whenever you need :3

thank you! You eat as a friend :) Im sorry I haven’t been doing the greatest 😭

uh uh neutron stars. Neutron stars. Supermassive black holes. There are actually 3 singularities inside a black hole. The BKL singularity (looks kinda like the word black thats how I remember it) is the one you’ve probably heard of and it’s the end of the line. As you get closer and closer to it your body would contort in all sorts of weird ways. So don’t fall into one I guess :D

Here is a small link of what it would look like (warning: math if you scroll down in the Wikipedia article)

BKL singularity - Wikipedia

There are also 2 more singularities! One thats in all black holes is called the mass-inflation or “infalling” singularity because it falls towsrds the center of the black hole from the event horizon of the black hole. It’s caused by all the stuff falling into the black hole after you building up due to the weird warping of spacetime. Unlike the BKL singularity, your body doesn’t stretch and squeeze infinitely by the time you hit it, so you could theoretically survive going through it.

The other one is only in spinning black holes and is called the shock or “outflying” singularity because it is coming from the inside of the black hole and going towards the event horizon. It comes from the cauchy horizon, which is a bonus event horizon in spinning black holes where the outward pressure from the black hole’s spinning (centrifugal force) overcomes the inward pressure from the black hole’s gravity. You would definitely die if you passed that horizon but the outflying singularity would hit you first, probably after the infalling singularity unless you were going at almost the speed of light. Like the infalling singularity, by the time you’ve hit the outflying singularity you haven’t been stretched and squeezed infinitely so you could theoretically survive. But you probably wouldn’t. Regardless you would die by hitting the Cauchy horizon anyway…

(You may have also been spaghettified by this point if you are in a smaller black hole)

🚨 interstellar spoilers below!!!!! 🚨

in interstellar, Cooper hits the outflying singularity right as he gets to the tesseract :) the tesseract is in the 5th dimension, not in the black hole still, which is why he doesn’t die hitting the Cauchy horizon. As mentioned before, to hit the outflying singularity first you’d have to be going almost the speed of light - to do this he would have had to slingshot around an intermediate mass black hole near Gargantua to get enough speed. The writers knew he had to hit one of the singularities since they are both going towards you in opposite directions, but did not want Cooper to hit the infalling singularity because if he did, it would mean he would be billions of years in the future and would never be able to reunite with Murph
