Cool.
Wow crazy I’ll make sure to adjust my schedule
So this means there are potentially millions of other universes whose portals are within our own?
Good, this one universe did seem a bit too small to hold my ego.If you mean entering a black hole, well, parts of you will probably make it in. After the spaghettification.
Can’t go to work if I’m 1 atom thick.
You’ll have to log in remotely via teams
I’m sure the audio won’t work in space, just like on Earth.
An atom will not be able to mute in a 10+ people meeting. You’ll fit right in!
You know they’ll still make you try though lol
what
Your life just got worse. You’re paying rent inside of a black hole.
Just tell your landlord we’re in a black hole and the rent doesn’t matter.
And then punch your landlord in the face. They are a landlord, they probably deserve it.
Isn’t matter the whole issue
You are matter but you don’t
You need to explain to them that rent isn’t matter, so it doesn’t matter.
I’m pretty sure that kind of knowledge falls under the “huh. Neat.” category anyway. It’s the kind of knowledge that, while a cool thing to learn, will have absolutely no bearing on my current life, and is not going to be likely to have any practical applications for many years to come.
It’s for the folks plagued by existential dread that need to know where we came from. Well son, it’s black holes the whole way down.
Heh. Ya take history far enough back, it’s all there ever was. 🤷🏿♂️
I mean, what if you happen to live trillions of years and reach the edge of the universe?
abolish all rent. see the cat. seriously!
Didn’t she-ra do something like that?
What’s this discovery?
As smug and pretentious Neil deGrasse Tyson is, he said it best, something along the lines of: What does this mean to us in the grand scheme of things? Nothing.
Are you saying that he said that about this in particular or that it’s a quote he says about loads of things? xD
On a side note: I don’t think we should hate on DeGrasse Tyson, because hating on him seems to be a meme that’s just gone too far. Isn’t it rooted in a literal 4-chan greentext? But I think he’s polite, nice, and the things people interpret as disingenuity are just his presenting quirks. Like the “tweeting the same mirror joke every month” actually has a more neat explanation.
All I know is that with a mirror, you can kiss yourself but only on the lips
As I often do, I disagree with Tyson, the model may help us understand the origin or nature of the universe someday. It’s just a model, but when a model can be tested or studied in some way, we generally tend to learn new, grand things about everything.
It’s not sensational, because it doesn’t say anything radical, other than show a very similar relationship between information systems in event horizons and the way our whole universe can be modeled as an information system.
In the grand scheme of things:
- We’re turbofucking the climate, even though we’ve understood the warming effects of CO₂ for 170 years, and had viable solutions to climate change for like 50. And yet we’re increasing CO₂ emissions year after year. It’s not certain the human civilization as it currently is will survive the next century.
- We’re throwing non-biodegradable plastics everywhere, even though we’ve known for like 50 years that it is devastating for many ecosystems and human health.
- Capitalism is squeezing the global working class ever harder with each passing day, and yet class consciousness is not growing fast enough, despite us scientifically understanding the unsustainability and evils of capitalism for like 160 years.
So yeah, in that grand scheme of things, making models of the larger universe is not actually that important. First we need to make use of the discoveries made way over a century ago.
If the knowledge of our problems prevents you from appreciating and finding any wonder in life and the larger universe, you have been defeated long before any of the actual threats have gotten to you.
I hope you find something that gives you joy or inspiration or a sense of grandeur in at least something. If it wasn’t for science we wouldn’t know about 2 out of three of those things, so maybe think how well your message is going to go over with people who are already aware of all that and just trying to find something greater in life than the perpetual, life altering struggles we’ve been dealing with and surviving for the last 200,000 years.

Bars.
It’s been a while so I’m a little hazy on the details, but in one of the Culture books by Iain M. Banks there’s a part where a bunch of Minds (for those unfamiliar: kind of beyond godlike artificial intelligences that run a utopian civilization, the eponymous Culture) are talking about how they can create simulations within simulations so perfect that it would be impossible to tell if you were in one, and what if their entire reality was just one in a long chain of nested, perfect simulations? But in the end they come to the conclusion that there’s no way to tell and nothing they can do about it anyway, so they might as well just get on with it lol.
Yeah, it’s hard to get too worried about specifically how the universe will collapse in 50 million years when I’m not sure our society will exist in 50 years and I’m not sure I will have a job in 5 months.
Anyone trying to frame this idea as worrying is trying to grift using science.
The idea in itself will never impact you personally. Most likely.
See, it’s just a model for understanding how information systems work, and you can model the entire universe as an information system which could be identical to what happens around event horizons. It could be a big deal for people trying to understand how all this formed and where we came from, if you’re curious about that kind of thing and have learned a bit about entropy and time and space and event horizons it’s a pretty remarkable idea.
But the most realistic thing that will come from it is just more questions, even if it’s true.
Best case: we learn that there are connections in time/space that we never were aware of or can use this model to predict particular kinds of spacetime effects and could figure out things like why space is expanding. Wildly best case: we figure out something about gravity we never considered and you get your goddamn hoverboards. Better late than never.
Makes sense. Everything in this universe sucks. Ha. I’m funny. Anyways…
Link to this? I had not heard that.
It’s not a thing. Or, like, this theory (“black hole cosmology”) has been around for ages, it’s not broadly accepted and I can find no evidence of NASA publishing anything explicitly in support of it. The pop-sci articles are all linking back to this study which decidedly does not make the conclusion the universe might be inside a black hole.
It’s by no means confirmed. It’s one theory out of many. The JWST data shows galaxies have a significant preference to all spin the same way. Mathematicians say this would be evidence in favor but not fully confirm the black hole theory (also called the Swarthschild theory if you want to DDG more). Some suspect it’s bias from the rotation of our own galaxy affecting the data and they plan to calibrate more
The observed direction in galaxies, if true, may be a hint towards an idea that is much older, and it involves the way the universe can be modeled as an information system and how those information systems function around event horizons. It’s hard to even give a fast summary without dropping an essay about a lot of our misconceptions about time and space and the Planck scale, etc. But the most we may get from it might be a better understanding of things like the actual shape of our universe and why/how it’s expanding and other observational goals.
Do you have an essay you could throw at me, or some kind of video that explains it in reasonably understandable detail?
I highly recommend PBS Spacetime, they did a number of videos on black holes, information and the holographic universe principle. Otherwise, I replied here with a short essay, but reading it I realize how woefully inadequate my description is.
I follow PBS Spacetime already, so chances are I’ve seen the videos you’re thinking of and can’t remember them offhand. I’ll give your link a read tho, thanks!
They can be a little hard to grasp, I had to back up and do some work before I connected it to other ideas that have been played with like the parabolic/hyperbolic universe idea. It’s kind of beautiful when you start to “feel” it and I think if anything, these ideas have value in their beauty.
They may not be accurate, they may not be useful, but neither are Monet paintings and we still stare at them for hours.
Anton Petrov also has good analysis of papers like that, here’s him explaining why no the observation does not support the black hole cosmology as long as we’re not cherrypicking https://youtu.be/xXSV9JaWxCE
Doesn’t mean the paper is shit, it always helps drawing parallels to notice differences and refine our equations, but the sensationalism must prevail for all the news sites reporting on it I guess.
“they plan to calibrate more”
Garrus approves.
It also depends on the definition of black hole you are using.
Because light in our universe doesn’t leave (escape) our universe it fits that definition of black hole.
I wonder if there are rules pertaining to black holes existing within other black holes. If black hole A is inside black hole B, does it make sense to have a meaningful distinction between black hole A and the other stuff inside black hole B?
If there was some slight angular momentum to things right after the big bang, would it not then make sense that everything would predominantly be still moving in that direction?
Does that mean we’re having spaghettification for dinner?
time to spagettify spaghettis, lets create hyperspag
I, for one, would like to see the cafeteria menus in advance so parents can adjust their dinner menus accordingly. I don’t like the idea of Milhouse having two spaghettification meals in one day.
Is it weird that I’m rooting for the black hole to destroy me?
