New Nasa data hints we could be living inside a black hole
Black hole cosmology suggests that the Milky Way and every other observable galaxy in our universe is contained within a black hole that formed in another, much larger, universe.
The theory challenges many fundamental models of the cosmos, including the idea that the Big Bang was the beginning of the universe.
It also provides the possibility that black holes within our own universe may be the boundaries to other universes, opening up a potential scenario for a multiverse.

yeah it's just the most headline grabbing possibility
Dude, after reading the paper from start to finish, this whole thing seems off.
106130 times.It's totally possible Shamir is right and that there really is a massive bias. That would be extremely cool. However, he's published numerous papers on this over the last decade yet still seems to be the only one who agrees with it. Which to me is highly unusual.
Can I just say your thoroughness here is a real fucking impressive skill. Thank you for sharing.
This guy reads.
Thanks for breaking that down, I wish newspapers or even BBC News did this. They do now have BBC Verify but its never super clear of their findings, certainly not in the format that you've just used. Perhaps theirs should be called BBC Balance. The only thing I would say with regard to your first point is that I'm not against the idea that any individual could make a breakthrough. At least with regard to theory.
We already know that throughout the history of cosmology, whole experts have been wrong when a new discovery is made. E.g. Highly likely that not everyone believed that Earth was centre of the Universe (like the earlier science communities claimed). The issue with this guy is he's using his own biased ideas and data and some people believe whatever is printed in a newspaper must be right.
Only silver lining is at least there clickbaity headlines give the public something more substantial to think about for 60 seconds instead of what the next Kardashian is up to...
To be sure, I agree with your interpretation of your first point. I was establishing that as part of a pattern rather than an end-all "you can't do science without a degree in that field", especially since applied CS is monumentally important to every field. It's that lack of formal education in cosmology combined with a pattern of only citing oneself for support of one's arguments combined with this being a long-held and broadly successful assumption combined with numerous cosmologists using a variety of methodologies which they think are acceptable combined with no cosmologists choosing to use his algorithm combined with ostensibly using his time with The Independent talking almost exclusively about deep cosmological implications.*
* This last one could be The Independent's fault; it's technically possible Shamir talked their ear off about CS stuff and methodology and previous attempts and what he wants to do going forward but The Independent only ran with the juicy sfuff.
This is what I missed on r/science. The thorough paper critique! Thank you so much!
Thanks for doing the news org's job for them. They either don't know how or aren't willing to do it.
@[email protected] (moderator), can we have a rule about clickbait headlines.
I’m kind of getting sick of these pop-science articles that exagerrate everything times 1000x in the headline. In any other discipline that kind of hyperbole would be considered a lie.
I'm open to the idea, but these articles bring out some of the highest levels of engagement, discussion and often bring in new readers.
Start reporting them when you see them.
I have always wondered about this and it's always been the question I would want to ask neil degrasse tyson about if I ever met him... I never realized there was a term for it or even other people believed it...
My other crazy theory is that we are always in a state of jumping between realities... As a state of self preservation... We exist in the reality where we keep living. With the possibility of realities being infinite and the possibility of a subset of those infinites being basically the same as the one you're in...
Who knows maybe it's just a reassuring way to be happy knowing that one day your actually going to die instead of all those times you have felt like you have almost died being truly a time you have died...
As I understand it, the idea of Quantum Immortality is a bit more nuanced then that. It's not that you would be "jumping between realities". It's more-so that, as the reality where you are alive is the only one you can possibly be aware of, any reality where you would die simply wouldn't be seen by you. The splits where the potential to die exist would only be seen as "close calls" to the consciousness that is you. It's more so a resolution of logic than a cross-dimensional mind swap. A pop-culture example of this is sort of seen in
::: spoiler Movie name The Prestige. :::
::: spoiler Extra Major plot spoiler Quick summary - in the movie, Hugh Jackman's character gets access to a machine that instantly duplicates him, which he uses for his magic shows. To resolve the "small" issue of there being an ever multiplying amount of him, he has a mechanism to immediately drown the version of him on stage when they disappear as the other version reveals himself elsewhere in the theater. At one point, he talks about how he was always terrified that he would be the one being drowned. There's a few interesting things about this particular line, the most pertinent one being that he is never the version that gets drowned, evident from the fact he is talking about it. Obviously this is just fiction, but I think it's a good illustration of the concept. There are also a lot of details left nebulous, possible details of which could suggest Destructive Teleportation instead. :::
Those bastards are always one step ahead of me... At least I learned what they call it...
Our consciousness continuously transferring between realities to stay alive is kinda crazy ngl
What's the big question you've always wondered about though? It's not clear from your comment
If the whole observable galaxy is inside a black hole...
Black holes get bigger and expand as does our observable universe... I always wondered if the two were connected...
But from reading everything in this post it seems like the theory doesn't hold up... But also who knows...
I like my other theory better anyways.
If we are going based off of evidence to support it, I wouldn't go crazy for your other theory either
My theory is that the Big Bang is local and there have been other big bangs outside our observable universe and our entire existence is inside a multi trillion year expanding and contracting space foam
Big Crunch and white holes and all that

The concept of recreation is pretty old
I recommend critically reading the paper. It is quite accessible to those with college-level science background.
Most importantly, it is still highly controversial whether this galaxy rotation direction bias actually exists. If you look at section 4 of the paper, the author is debating against different groups that did similar surveys and found no bias. Someone needs to actually work through this author's methodology as well as those of other groups and figure out what is going on.
If there is indeed a bias, that is super exciting! An anisotropic universe due to being in a black hole would be a very cool explanation. But given the ongoing debate, a general-audience publication like Independent presenting this rotation bias as a given fact is very poor journalism.
Last few paragraphs...
That's leading me to think that that's actually the more probable explanation, and the black hole idea comes in a distant second in terms of probability, but is much more attention grabbing/sensational/click-baity.
The black hole idea is actually weirdly solid, its a case of the maths says we definetaly should be but observation and just intuition says its crazy. If you consider the event horizon to be the surface of a volume, black holes get less dense as their radius increases, you can have a black hole with the same density as rock, water, air, even the miniscule density of the gas in a vacuum, so long as teh black hole is large enough. The average density of the observable universe is higher than the density of a black hole the size of the observable universe so technically we should be in one.
Technically this doesn't have to affect anything, larger black holes can have gentler gravity gradients and nothing in physics actually demands all the mass inside be concentrated at a miniscule central point, it just works out that way for black holes of the size we've seen so far. So the entire universe could be a black hole (assuming its finite) with the event horizon just being functionally inacessable and the black hole so large that internal conditions aren't really influenced in any way.
Surely at some point it stops being useful to apply the same terminology to such vastly different concepts. If the universe is a black hole and Sagittarius A* is a black hole then "black hole" doesn't communicate anything effectively outside of extremely niche astrophysics conversations.
The mass of the visible universe is apparently enough to make a black hole with an event horizon ten times larger than the visible universe's. I don't understand how that hasn't happened already, but apparently it just doesn't look like it's happened ("unless...").
It could totally have happened already and we just don't notice, though there's kind of a critical size where a black hole just gets infinitely big as adsorbing a stray hydrogen atom in the vacuum of space increases its radius enough to encompass multiple new hydrogen atoms and the whole thing just expands to encompass the entire universe. Kind of when everything is a black hole then nothing is a black hole sorta situation.
Some of the findings match a pre-existing pipe dream but this boring alternative is pretty neat too:
It's funny how often surprising results are just "ah shoot my bad. Tool is busted"
That alternative idea seems like an Occam's Razor type explanation. I like it.
Okay so I have a basic understanding of orbital mechanics, I would say astronomy and astrophysics is a hobby of mine, and my content subscription list is filled with space nerds talking about nerdy space stuff.
I do not understand how the rotation of the milky way could be making it seem as though other galaxies are rotating a specific direction.
I understand if you spin in place and are looking at something above you that's spinning in a certain way, it might appear to spin the opposite way it is relative to the floor, because you're spinning faster. However, my problem understanding stems from the fact that the milky way is huge and we are rotating around a very large axis, not at a rate that my common sense tells me would be noticeable.
Maybe I'm just not giving NASA and ESA enough credit for their measurement capabilities, but I don't get it.
And maybe I'm so far off base someone is face-palming into their screen in disappointment that I could choose be so wrong.
If anyone could explain, or post a link to a space nerd talking about nerdy space stuff thats relevant to the answer, please edumacate me!
Yeah it's like either I don't understand 3D space or they don't. Clockwise to what? What if you go stand on the South Pole, does it all reverse? Maybe they need to read Enders Game again.
Do you have a link to that research?
https://academic.oup.com/mnras/article/538/1/76/8019798
It is an observation consistent with black hope cosmology, but other explanations are possible too, so nobody is claiming it's proof
Thanks Obama
Yeah!
LOL. Oops. Edited.
I've kinda thought that were some n-dimension universe getting sucked into an n-dimension black hole, and what happens as that universe crosses the event horizon is the big bang, the arrow of time. And all of the matter and forces that have them appearing to interact is just some beautiful n-dimension spaghettification.
The universe isn't expanding; all mafter within it is shrinking, being crushed. all matter appears to be accelerating further and further away because, well, it is. From our perspective.
Think of our whole universe as the most epic allegory of the cave possible.
I'll go back to ripping my bong now.
Dude
If this is true, do you think time exists outside the outer black hole? In the least, I might imagine it's moving very differently than our interior universe.
Idk I've thought about it and it's like, if time is created by the passage into the event horizon and it's an artifact of the n-dimension universe it can both imply that this n-dimension universe doesn't have "time" as we know it and our experience of it is, again, artifactual. However, the "movement" of this universe toward a n-dimension black hole kind of implies time, at least in the sense that we understand it (physical state changes of matter. It was there, now it's here! How'd it happen? Time!)
So... "Yes" but I would wager if my stoner theory holds gravity (pun intended) that whatever "time" exists in a parent n-dimension universe is not the same as time as we understand it? But maybe it is! Idk. Someone ask Neil degrasse Tyson why I'm wrong. And dont let him fool you that my model wouldn't account for red and blue shifts as our little matter-islands shrink and "accelerate away" from one another. It do! 🙂
Also fun to ponder with my silly stoner model here is that... Well... There is a supermassive black hole at the center of most galaxies... Like it's some sort of iterative and exponentiating recursive process? 😵💫
"Time" exists in any reality that isn't static, it's simply the concept of being with any measureable change. Doesn't have to be linear or consistent but if there's two quarks then there's time.
It does seem somewhat likely that the flow of time would be different if other universes exist. Hard to apply our physical laws to guesses entirely outside observable reality.
The Frensh-German TV-Channel Arte published a Documentary about the theorem, that we are probably living in a black hole. According to them its based on the work of Nikodem Poplawski (mathematician and physicist). It was a kinda nice theory and seemed appealing. But Im no scientist and I have no idea about higher Math and Physics. Sadly, on the German Arte-TV-Site the video is not avaible anymore. (According to German Law public-TV-Channels arent allowed to keep their Videos up online unlimited) https://www.arte.tv/de/videos/101940-002-A/leben-wir-in-einem-schwarzen-loch/
But I assume there are other sources, probably even in other languages.
if you can call that living
Oh sure but when I say this I'm "too high" and need to "quit smoking." I been told y'all.
Kurtzegat (spelling debatable) did a video on this almost a year ago in case anyone wants a 10ish minute simplified version
I always thought this was the consensus, but turns out, it was just as far back as we can go where physics as we know it work. Not everyone claimed that nothing existed before.
Thing is that there's no "before", because time itself started with the big bang. The questions to ask are: is there anything other than our universe, and does that even matter? If nothing can get in or out of our universe, then there's no way to prove the existence of anything outside of it and there's zero impact one way or another.
Time as we know it started. That doesn't mean time as we don't know it wasn't around.
I saw some science stuff on YouTube the other day that explained that the expansion of the universe seems to have started before the big bang. Also that the expansion is what caused particles to come into existence from nothing and thus creating the big bang.
Found it: https://www.youtube.com/watch?v=OHdUFPAK7f0
Anyway, you're right that whatever was before or outside the universe is irrelevant to us. However, if we can get closer to understanding as much of the process as possible, it might still pave the way for something that we can use today.
"Thing is that there's no "before", because time itself started with the big bang."
Good to know modern science is catching up to fourth century theology:
"There was therefore never any time when you had not made anything, because you made time itself."
Saint Augustine posited in "Confessions" that before the Universe was created there was no time. Also, that the Universe was not made in any "place" because no place existed before the Universe existed(space is also created with the Universe).
For exact argumentation you can refer to the text, I suppose(chapter XI). I just think it is fascinating that conceptual tools and concepts developed by theologians and philosophers more than 1500 years ago are still incredibly useful.
They're not even a little bit useful. Using tautilogical arguments like this are actually a disservice to science, and anti-thetical to the scientific method.
I fail to see how this is tautological.
How is that antithetical to the scientific method? Science uses routinely uses manufactured conceptual instruments, theoretical objects and even applies mundane concepts in a metaphorical way. Science is a struggle to create theoretical frameworks that explain observations, and this is why in times of crisis science often turns to philosophy, since old frameworks might not be doing it anymore and philosophy provides new ones, as it happened with the crisis of classical mechanics, for example. This is a relevant example because it relates to the issues of space being absolute or relative and time as well.
If i have to explain to you why this is not helpful to science, I'm not sure you'd be convinced regardless of what I have to say.
There's debate on the existence of singularities and certain shapes of the universe can give the impression of accelerating expansion
Well, they still have a mass (and some form of "size") iirc, that can expand as they absorb things
Bruh I'm just trying to get through the workday I don't need this on my mind!
I honestly appreciate that we don't understand the universe. Theories keep evolving and that's what science should look like. If we can't question "established" scientific theories, we have abandoned the scientific method. Strong theories hold up. Like the theory of gravity, although even there I'm not convinced we have a complete understanding. Good answers are good, but who knows what we might be capable of if we keep pushing for more.
Chat is this real?
much larger universe than this? are you fucking kidding? we might just as well die then.
Or you might just as well live given the absurdity of it all.
You both make excellent points!
Pulls deeply on the cigarette, stomps it out and then waves the pistol's barrel towards a dark corner of the room.
"Now get into the box..."
eh why not ...
Because it's not what you expected?
I can assure you, whatever you expected is just as strange and absurd as this.
Let me put this in another way:
To think that time might have not existed, then started up at some point, breaks my brain.
To think that time might go on for infinity in the past, with no starting point, also breaks my brain.
No because it is just so crushingly huge. I mean maybe humanity could understand and even partially explore the universe at some point. But trying to understand a universe within a universe, fuck that. Whose to say it is not a sequence of universes?
Man, this is so cool!!
I like these observations and theories, despite them being the ramblings of very ignorant creatures (all of us as a species).
This said, we don't have evidence to suggest we aren't the most intelligent creatures to ever exist. It seems very, very unlikely... But, such is the rarity of life so far as we've observed.
So... These are lots of fun! If not for any other reason, than for the reason of humbling us all.
black holes all the way down?
Explains the warped timeline
Why aren't we all spaghetti, then?
All the matter in our universe was sucked into the black hole and then coalesced into all the forms that exist now. (Presumably, and if this hypothesis is true)
The way things are going, more like we got tossed in an endless trash can. I don’t blame the Vulcans.
So it might be turtles all the way down?
Ok yea that makes sense because we’re in hell
Sooooo the expanse was right?
I'm mostly curious how higher dimensioal space could explain (perceived) expansion. Like: maybe we live in a 3d bubble embedded in an n-d space which keeps on collapsing, pouring more and more energy into our "universe"...
That why our timeline seems to keep radically changing?

But if this leaves anyone in a philosophical mood, I leave this video on a comic book villain that unpacks into a metaphysical wonderment.
https://youtu.be/fcJ8QmogoXY
I’ve always believed that our entire universe is the inside of a gravastar in a 4D-universe. Our universe is the false vacuum inside it, permanently in superposition. We’re just one of the infinite potential states the wave function of the Bose-Einstein condensate inside could collapse into.
Oh, and gravity as a force would be the result of the 4D gravastar’s centrifugal force as it rotates on 2-axis, and that would be why we can’t figure it out.
At least that’s what I’ve always imagined reality. (Also known as my rambling brain doing its best in the moments between wakefulness and sleep)
Edit: tbh 5D/3-axis makes more sense
You might like this video by PBS Spacetime. I'm not sure how this relates to your centrifugal force idea, but we do actually know a few things about "what gravity is" that are really interesting.
Oh, I’ve seen this before! Although my interpretation is purely spatial and lacks any temporal component aside from the act of rotation itself. So it’s still applicable.
What did they drink?
Go Wildcats!
Whoa.
If this is true, this makes sense to me. Right or wrong, I’ve never been comfortable with the idea of infinite, endless space. Like God just existing for all time, never having a start or a stop is a cheap way of admitting we just don’t know, and may never know. Why does “God” and the universe get to be treated differently than everything else? Things come from other things.
I digress. I have often daydreamed that our universe only appears infinite because it’s actually a sphere or a bubble, and what we see as infinite is merely a reflection of our finite space like an infinity mirror would look.
But those ideas are just that: daydreams. If anything, I hope that the scientific and academic communities can keep open minds and not dismiss these radical ideas because it contradicts their religious fervor.
God was created by man. Change my mind.
“God” is what people use to explain the unexplainable. Change my mind.
Yes, it's called Trump and it's sucking up fucking everything.
The real Trump Derangement Syndrome is when you can't stop posting his name even on completely unrelated topics.
Can't i just have one article that doesn't mention that fat sack of shit. This is actually really interesting physics, and you had to go and ruin it.
Obama turned up, too, but it was funny.
Back in the days we'd just make yo mama jokes.
Yo mama's so fat, her mass affects the spin of galaxies! Or her mass is affecting our perception of those galaxies. We're not sure yet.
i know trump and elon are big topic now, but didn't expect to show up in an astronomy post
Yo, can we get like 5 minutes to revel in the non-political, world-changing good news?
To quote a wise man:
