This is a postulation not a discovery.
Someone did a weird math thingy that gave a word result and this was how they tried to explain it. There’s been zero confirmation this is actually the case. Just like they can’t decide if dark energy/matter is a thing.
We have a theory for expansion of the universe. It is called “the big bang theory”.
However according to the math our universe should slow down expanding, but we can observe it is speeding up. Solution? Dark Energy.
There are models that try to simulate the orbits and shit of things we can see. Now those models aren’t working however… Solution? Dark matter.
This is very run down concept of what dark matter and energy is. Basically shit we need for the math to work out to the observation we make.
However I don’t think we are inside a black hole. This would mean that instead of mostly nothing our universe would be cramped with matter…
Difference being that we understand dark matter exponentially more than dark energy. We can actually observe it’s gravity affecting light.
There’s also cyclic conformal universe theory, put forth by Penrose.
Where once you have an empty enough space… its mathematically indistinguishable from a singularity.
So, if its true, then yeah, we could be inside of a blackhole/singularity.
At this point, that doesn’t really matter.
There’s also been some major leaps in dark matter physics in the last few years. Revisiting primordial black holes using lasers and microlensing might actually be able to get supporting evidence here before long if the hypothesis holds.
PBS Space Time has a good video breaking this possibility and methodology down.
If you take all the mass in our universe and run it through the Schwarzschild equation, you get a black hole with about the same radius as our observable universe.
Things don’t need to be tightly packed to be a black hole, there just needs to be enough stuff in an area.
So, dark matter and energy is the Universe’s theorized version of the Kelevin (from The Office).
Man I really wish we had super fast space travel like star wars…
May be that’s why it sucks to live here… It’s related
What if we’re not in a black hole, but in the aftermath of a vacuum decay event?
We’re inside a dust cup?
What if Zelda was a girl?
That is literally what the current big bang theory says! en.wikipedia.org/wiki/Inflationary_epoch?wprov=sf…
Look up vacuum decay. It’s theoretically a thing that can rewrite spacetime at a lower energy level, and would expand out from a point in a bubble. The expanding bubble would erase and rewrite everything it touched into the lower energy level.
Well, that might suck slightly less in the long run?
That depends. The chances of finding other life are lower. That would also make a cosmic horizon that we would never be able to see beyond. It would make us unable to find the beginning of everything.
no my vacuum is working fine, thanks
But is your refrigerator running?
We should all be celebrating our good fortune, protection against a dark forest strike!
Sucking us into a black hole WAS the attack.
Dark Forest theory is just way for a Chinese author to make up bullshit nonsense physics to turn 3D space into 2D space via Clarktech while desperately trying to not piss off the CCCP.
What’s wrong about it? It seems like the obvious assumption that running into intelligent alien civilizations would be extremely dangerous.
Liu closed his eyes for a long moment and then said quietly, “This is why I don’t like to talk about subjects like this. The truth is you don’t really—I mean, can’t truly—understand.” He gestured around him. “You’ve lived here, in the U.S., for, what, going on three decades?” The implication was clear: years in the West had brainwashed me. In that moment, in Liu’s mind, I, with my inflexible sense of morality, was the alien.
And so, Liu explained to me, the existing regime made the most sense for today’s China, because to change it would be to invite chaos. “If China were to transform into a democracy, it would be hell on earth,” he said. “I would evacuate tomorrow, to the United States or Europe or—I don’t know.” The irony that the countries he was proposing were democracies seemed to escape his notice. He went on, “Here’s the truth: if you were to become the President of China tomorrow, you would find that you had no other choice than to do exactly as he has done.”
It was an opinion entirely consistent with his systems-level view of human societies, just as mine reflected a belief in democracy and individualism as principles to be upheld regardless of outcomes. I was reminded of something he wrote in his afterword to the English edition of “The Three-Body Problem”: “I cannot escape and leave behind reality, just like I cannot leave behind my shadow. Reality brands each of us with its indelible mark. Every era puts invisible shackles on those who have lived through it, and I can only dance in my chains.”
Dude. Relax. It was fiction.
Except from aliens that are also stuck here with us
We’re not stuck in here with them. Their stuck in here with us!
Anyone got a link to either nasa or a good article explaining it?
Scientific American points to an important fact. *With our latest surveys, such as the Dark Energy Spectroscopic Instrument (DESI) and Euclid, by my very rough estimation, we’ve taken pictures of somewhere around 100 million galaxies out of the two trillion or so estimated to exist in the entire observable universe.
Shamir’s paradigm-shattering conclusion relies on 263 of them.*
They are discussing bias in the selection
I can barely afford rent!
Well… the good news is you can stretch your income a bit further with spaghettification!
nuclear pasta is very energy dense
Beans are economical too
NOT “discovered inside black hole”, just gained further theoretical evidence for the Earth being in a less dense area of the universe. There has been actual evidence of such for some time (at least a decade), but there is uncertainty at such large scales so it cannot be called conclusive based only on a couple types of observation that may have erroneous procedures.
But then there’s the guy who added all the mass and energy of the observable universe, calculated its’ Schwarzschild Radius, and came up with 13.8 billion light years.
There’s also how our observable universe’s Hubble Horizon acts like a black hole event horizon, the way in which even the speed of light is insufficient to escape beyond.
A lot of the math inside a black hole is eerily similar to the math of our own horizon, as traced by the age of the universe plus the speed of light.
That is simply how horizons work. It’s nothing magical about our universe. It’s discussed in every astrophysics course worth its salt year one…
PBS Spacetime has many episodes on horizons and this very concept comes up a lot. It’s also equally probable using such simple logic that we are in a white hole given the effects of dark energy.
Nah, there’s been a bunch of discussion about our entire universe being inside a black hole.
Nah, that discussion is MUCH older and including much of the “news” about it, is completely and utterly misinformed BS.
There being a “bunch of discussion” doesn’t prove anything?
so basically We’re out in butt fuck no where in space and the aliens aren’t coming any time soon cause they essentially live in New York City and we’re in a town in Iowa that no one has ever heard of.
Less dense as in ~20% less dense. It’s absolutely nowhere near the population density difference of rural vs NYC, even assuming matter == chance for life, which simply is not the case.
It’s entirely possible that there are no aliens in the “New York City” part of the universe.
Dense regions of space will have much more interactions between stellar systems and may not be stable enough for life to evolve. It could be why we haven’t seen anyone else, they’re all in their own little pockets of peace.
Being from Iowa, I take offense to that… But yes, you are correct.
Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the galaxy.
Yes, we ignore it. Given the size of the universe, if being inside a black implies any conseqences that will ever hurt us, it will be a process that takes billions of years to develop, giving the human race billions of years to either become extinct or solve the problem.
There is no problem introduced by noticing that there exists a horizon to the universe. It’s also in no way what so ever a new “discovery”, but a basic concept based on how horizons work in the first place.
There's that and what seems to be a preferred direction of spin on a galactic scale. But it's not every galaxy.
Considering NASA could be canceled by an ass hole, I think we have other problems.
I thought black holes aren’t actually holes at all, they’re literally gigantic physical objects because they’re dead suns with shockingly high gravity that prevents light from escaping; how could our universe be inside something like that?
Firstly, a black hole isn’t an object, really. If you manage to compress enough mass in one place, gravity becomes the dominant force and the mass collapses into itself, eternally compressing and densifying. This is the singularity at the center of a black hole, and we use the term singularity because it’s describing a single unmeasurable point in spacetime.
Next point: high gravity curves space. Light only travels in straight lines if it can get away with it, so when light bends in space it’s because the space being traversed is deformed by gravity. Like, the Earth is, as far as it cares, going in a straight line that happens to curve back to where it started. If gravity is strong enough in a region, all possible “paths” through space become bent inwards to higher gravity. Like, even a perfectly straight line away from the black hole will be forced inwards again. That’s the event horizon, the region in space around the singularity where nothing can escape anymore: all paths go deeper into the black hole.
Third point: weird shit happens inside the event horizon. We’re well into Math now because we can’t actually see inside these things, but we can use math to theorize and describe the inside of a black hole. Basically, time and space switch places inside the event horizon. Because every possible direction you can move in only takes you deeper, that means the future is the singularity, and as you move forward in time you move closer in space to it.
So in net: they’re not really holes and they’re not really physical objects: they’re regions where every path in space is forced into going towards the singularity, which is itself infinitely small and infinitely dense.
I took a physics course at a community college over 20 years ago and one of the things that stood out to me was the professor telling us not to overthink or assign too much romanticism to the idea of black holes.
His message was basically “it just means the escape velocity is greater than the speed of light… if you plug the size and mass of the universe into the escape velocity formula, the result you get back is greater than the speed of light, so our entire universe is a black hole.”
If this was being discussed at a community college decades ago then I think the new discoveries aren’t as revelatory as they would at first appear to the general public.
When I first saw pictures of galaxies as a kid I noticed they all looked like black holes.
In a way we’re all just bits of organic matter mid-flush, waiting for the Drainpipe of Destiny

Orr, you’re missing the obvious alternative here - the guy was a legendary level scientist, but the government stole his research and threatened his family and sidelined him into being a community college professor so that no one pays attention to his “drivel” so that they continue to control us into being workers for the capitalist pigs
I mean, the model was first developed in the 70s so maybe not that specific guy
Would make for a decent flick, get Hollywood on the call
another thing I learned at some point: Just because a physics formula returns a result, doesn’t mean that it’s reality
Iff the rules of physics are accurate then it does, but we don’t know that they are. In fact, we’re pretty sure we’re missing some things. See: The Crisis in Cosmology.
TBF black holes themselves were originally just the result of a Physics formula, but they eventually turned out to be a “reality”. Sometimes that shit happens, yo.
Interestingly, galaxies at the edge of our ability to perceive are in fact receding away from us at velocities greater than the speed of light.
Maybe it’s because they are outside the black hole and aren’t time dilated.
Theory is one thing.
Observation is the next step.
Absolutely. I don’t want to minimize the importance of the new discoveries in any way; I’m just saying this isn’t the great surprise the original post seems to think it is.
Nah really it was probably some small thing the media got a hold of and just ran with. I think you’re spot on
And a relevant smbc for good measure.
hasn’t this been a theory for a while now? The event horizon of a black hole keeps information minus one dimension. and the theory goes that our entire universe is just at the edge or a black hole in a 4D universe
Yes. It’s basically how the holographic principle got started, and that was decades ago.
You better start believing in compression systems you’re in one
Ok I've been meaning to ask this in the Space community or the NoStupidQuestions community. I've seen this news circling around the past 2 weeks and have been watching videos of people talking about it.
Someone correct me if I'm wrong but I think the gist is that astronomers discovered with the JWST that some galaxies at the end of the observable universe appear to be younger than they are supposed to be. So it kinda blows a hole in the big bang expansion where objects farther away should be older. And that somehow ties in with the theory that our universe is inside a blackhole.
It's fascinating but I don't know what to do with that information other than just be fascinated. I think it was Neil deGrasse Tyson who said "what does it matter to us? nothing", because us being in a blackhole doesn't change anything in the scale of our universe.
We also have to remember that we can only see a bounded sphere of the universe from our frame of reference.
If we were to move our observation points to elsewhere in the universe, we’ll be able to see more of the universe and challenge our current theories.
The JSWT sees only what it can, and our theories about the universe can only extend as far as that evidence. Those galaxies might appear to be younger, but the science is never finished!
Probably goes without saying
From what I’ve seen, it’s not that they’re “young” galaxies, but that they shouldn’t have had enough time to develop if the universe were truly so crazily homogenous from the big bang. It doesn’t necessarily disprove the big bang, just means the universe might not be as “smooth” as previous assumptions.
Maybe the far away galaxies are just the close galaxies seen from the other side?
The Hubble radius of the universe is also equal to its Schwarzschild radius, which is a requirement for any “we’re inside a black hole” theory.
I’ve always liked this theory, imagining the cosmos is just a series/web/tree of black holes draining into the next. Everything gets recycled eventually.
Another big part of it is that if the big bang happened evenly then galaxies and other objects should be spinning in random directions. So far that's not what's been observed. There seems to be a preferred direction everything spins in.
we could acknowledge it as a possibility AND work to better our um… local frame of reference.
I mean, I think it's fair to ignore it 99% of the time. Frankly, as much as I love space science and science in general, we all should have a responsibility to solve real problems here and now. That's been my issue with a lot of science, currently - we need problem solvers rather than idle explorers.
Don’t get me wrong, understanding the nature of the universe is valuable and noteworthy. But how would that information meaningfully impact anyone’s life or change their behavior or worldview beyond a general awe at the unfathomable mysteries we already have towards space as we’ve understood it for centuries? Am I meant to stare up at the sky from 8:15 to 8:30 every other night with my mouth agap while I try to wrap my mind around the spacetime bubble we all exist on the surface of? Or can I just eat dinner?
Tax breaks for the rich is the only solution
paying rent sometimes feels like throwing money into a black hole
Okay, so now you can barely afford your rent inside a black hole. Enjoy the enhanced granularity of your desperation!
Both are fair and valid.
Peaceful science & good housing should go hand in hand.

I mean, we can talk about it for a bit, Angie, if it’d make you feel better, but that’s really about it, honestly.
