We tend to imagine there are connectings between things that we don’t understand. Quantum mechanics and consciousness, aliens and pyramids, black holes and dark matter, dark matter and dark energy, dark energy and black holes. Usually there’s no real relationship whatsoever, but this last pair-black holes and dark energy being the same thing-has received some recent hype in the press. Let’s see if it might actually be true.

Hey Space Timers! Want to deep dive some Space Time and watch ALL the episodes referenced in this week's episode? Then check out our episode companion playlist: clip-share.net/p/PLsPUh22kYmNAO4wmE0sua4zqcs0D7eqv7
That's a great idea! These videos are so massive in their undertaking that at least 5 other videos can be directly recommended, while those 5 will each lead down their own rabbit holes.
If we live in a blackhole, this is all moot.
Hey could anyone help me with something.
The geometry around a blackhole just simply would not allow for this correct? The very space around a black hole falls INWARD toward the singularity.
To get expansion the solution for that is a whitehole. Isn't it?
@king_ Tesseractthere are many unknown forces around black holes. Atom nuclei we predicted many particles to explain the stability of nucleus , simmilar theory required to explain structure of black hole😢
If the new theory in the video is correct, then you can bet that black hole's dark enery is also responsible for the phenomenon we now ascribe to black matter.
Thanks for the shoutout Matt and co! Great to see some of the historical cosmological context covered 👍
Love your content Dr. Becky!
This is the Clip-Share space channel synergy I've been waiting for!!! 😃
Awesome channels, both Dr. Becky and Matt's PBS Space Time!!
Although I agree with being skeptical about a new observational experiment's conclusion. There are other observational experiments that had reached the same conclusion. Gravity = the spaceless and timeless vacuum energy state of matter!!! :)
Here's the link to Dr. Becky's video on that topic: clip-share.net/video/3gg1OS435UE/video.html
I am but a very ignorant electrician , I have followed this channel for year , I get maybe 30-40% of what’s being discussed , but your presentation skills, you vibrant explanations , and your sheer intelligence makes every video a joy to consume , thanks for what you do
I remodel homes. Aka glorified handyman. I've been learning about astrophysics for decades and still I am unable to grasp most of it. I've always wanted to know the fundamental truth of reality.
Same here, long time follower of the channel with zero background in astrophysics: I love the subject so much that I keep watching although I constantly make almost nothing out of it 🥲
"the smarter your mind, the smarter your god"... 100% factual truth
"ignorance is not a disease, but a state of mind"... also 100% factual truth
I am over 60, and I can't stop educating myself, lol
I know, I will continue learning daily - till the day I die....and that is a cig way into my great-grandmother's words "You live 100 years, you learn 100 years, yet you'll die an idiot".
DO NOT stop learning!!!
@Francesco Segrè keep watching... it will come!
PBS Space Time is in my opinion, the best science show I have ever seen. It's hard to put into words how much I love your videos. Absolutely fantastic work.
Check out Sea, also Space is Ace
@Ryan Romero Will do, thanks for the tip
PBS Space Time, SEA and Anton Petrov are my top 3 space related channels. No sensationalized click bait, just straight up current scientific information. What a treat!
add cool words to the mix. dr kipping teaches at columbia and is a fantastic communicator with a way with words. him and SEA are my all time favorites.
Thanks everyone for great tips on channels, they're great!
I love how respectful you are in criticizing others' work. It's a hard skill to acquire, and you set a great example.
He does it in such a way to where some people won't even notice. A beautiful skill to have.
It didn't strike me as criticism, but rather, a healthy degree of cautious scepticism. The grander the claim(s), the more it behoves the reader to remain cynical. And from what little my Neanderthal brain comprehended from this video, this paper's proposing some pretty massive claims (pun intended).
I feel the more time you spend trying to be productive and running into your own limits, the easier it can be to be humble critiquing others.
Because it's not critique.
He's just performing the script!
While I was watching this I took note of just how clean the camera footage is, and how well it's blended with the background and animations. Overall the visuals of videos on this channel are really well done, and I wish to voice appreciation of that.
Thank you Matt! I was wondering if you and your show could cover "Quantised Inertia" theory at some point? A vehicle going to space to test the theory is going to space on a Falcon 9 soon, and I think more people would be interested to hear about it.
Props to your motion design/VFX team. This might be some of their best work yet
Came here to say the same thing. Amazing visuals on this episode!
let’s just say everyone has their standards.
it's AI 🤣
@HellXels no it does have that unique style, not AI
@Windows XP memes and stuff lol Prompt: Graphics in style of PBS spacetime
AI: Gotcha fam
I've watched a number of decent videos on this topic. That said, I've come to expect PBS Space Time to provide the clearest explanations, and this episode did not disappoint. 🙏
Dear brothers and sisters,
I have published a series of papers (totally 9 nos.) on "Theory of Singularity"
[Volume 10; issue 03,04; 2023] - arcjournals - International journal of advanced research in physical science - Open access for free download.
1) New representation of Gravitation
2) Structure of black holes
3) Finite structure of space-time.
4) Real dimensions of space-time
5) Singularity
6) Source of dark energy...etc
"Fundamental theory of Singularity" - The new proposed study that serves one fundamental for general relativity and quantum mechanics by solving the incompatibility between them...thank you
I really appreciate the detailed breakdown at the end! Great to see specific reasoning as to the strong and weak points of a result :)
Currently the places to hope for a real space craft engine capable of taking us into the cosmos are in a few places as I understand it. There is little to no hope in negative energy being a thing. What does a graviton look like is definitely going to answer some questions. Are there fundamental forces we haven't discovered yet is lastly also super important. Fact of the matter is, light speed is not fast enough. We need to understand energy better. I suppose we will eventually start blowing up anti-matter bombs to observe conditions no longer existent in our current state of the galaxy and unlikely to occur again. Maybe some answers will be observable we haven't considered in such high energy events we can collect every possible information off of.
I’ve thought like this for a long time, I m glad to see that theoretical physicists have at least considered all this. It may be wrong but I’m glad curiosity allows all possibilities to smash up against evidence.
Great video! This is a really intriguing idea, and one can see how people might wish it into existence. It's a novel take for sure, and it will be cool to see if the paper is dissected seriously by the community.
in the english language "black" equates to "dark"...that's good enough for me.
I love the phrasing “For complicated reasons due to relativity being weird…” 😂 So true!
Wonderful video! I think I understood only 5% of it but it’s still wonderful! Great work!
5%! Look at Ms Big Brain here 😅
Damn, 5%?
Spacetime tomfoolery
My man understood regular matter and ignore dark matter and energy lol😂
You guys are getting percents?
Been waiting for this one! Thank you Matt and team for another amazing video on a most fascinating subject! Visuals are insane btw, so well crafted.
"For complicated reasons due to general relativity being weird" is now my go-to excuse for basically anything 😂
"You've been late to work three times this month"
@Jengleheimer Schmidt "But time is relative to each observer, so from my perspective, I wasn't late, you were just early."
@Bradley Walker ...now you sound like key and peele doing NDT...
My brain was blown as usual. Thanks, Matt.
I always thought a universe was inside of black holes. Dark matter was gravity pull of massive space objects around the black holes. Also, the expansion and the void energy are the absorbing of mas into black holes. But I'm just someone who enjoys learning such a thing, so their probably lot stuff I don't know that make this wrong. However, it would make a good story.
I always appreciate the detailed visuals. Keep up the good work!
I always look forward to the PBS Space Time video when a hot topic pops up in cosmology.
I appreciate that the skepticism is expressed respectfully on this channel. And there should certainly be skepticism on these claims, but it is better to consider the possibility that the authors could be on to something rather than arrogantly dismiss them with a wave of the hand. This channel gets it right.
Thanks for the continuing effort to help explain the topics to someone like me. I am a highly interested layperson, and the vast majority of other channels are either too basic for me, or far beyond anything I could understand without actually being a researcher in the field.
I love this jab at quantum consciousness. It feels fitting for the topic. I have a hard time making sense of it and it was explained to me in detail for a class I’m taking for my degree.
Could black hole rotation cause the black holes to appear more massive? Like how a spinning whirlpool is able to consume more water.
"For complicated reasons due to general relativity being weird" is now my go-to excuse for basically anything
Very insightful and well argued/thought out, thanks matt!
I've seen almost every of your videos, for past 6-7 years, each of them terrific quality. Never bias, always factual with passion and realnest. Awesome content! 😉😁
Agreed. Had to laugh at a guy in one of the comment replies above you saying all Matt does is make up "pure unadulterated nonsense", and hopes that people that understand science don't see it and that enough people that don't understand the science believe his "nonsense".
And what have you learned in 7 years?
I'd argue that PBS space time has a clear pro-reality bias.
@FussyPickles it's a bot
I’m glad Matt wasn’t totally convinced of this paper’s claims, and neither was I. Of course, it’s nice to hear alternative takes from time to time, especially concerning things like dark energy, which we still don’t know a lot about. But at the end of the day, the simplest explanation for dark energy is it is just the inherent energy of the vacuum of space. Connecting it to black holes as some sort of grand unification seemed like a big stretch to me. Still, it was interesting to hear about and pick apart nonetheless.
The explanation of hawking radiation (2 virtual particles on either side of the event horizon are forever separated) may be part of the key to understanding the difference in the observed size of black holes vs their theoretical size due to accumulation of matter.
would the time dilation beneath a black hole's event horizon prevent the matter inside from actually ever reaching singularity?
... from whose perspective?? To an outside observer, the object inside the black hole slows down and becomes frozen. But to the object inside the black hole, it would seem to continue moving at the same speed, while the outside observer would appear to move much faster. It's all relative. :)
Always nice to see Soviet scientists given the credit they deserve!
We couldnt have done it without Tsolikovsky
Thank you for another informative and interesting episode!
This is the first "dark energy is just..." theory that actually makes some sense. It's probably wrong, but it's not obviously wrong, that's always a good start in science.
Einstein and his greatest blunder is a fascinating story, all the more so when it turned out he was so damn smart that he actually got it right, for the wrong reason.
Great video. With dark energy, I suspect it's a case of the theoreticians getting way ahead of the experimental data available. Or as Asimov would put it "Insufficient data for a meaningful answer".

Congratulations on acknowledging Dr. Becky. Wish i could listen to both of you tear apart an astronomy topic sometime.
Just a thought: this kind of widespread interference “at a distance” may be related to quantum entanglement
It's always made the most sense to me thinking of black holes as tears in spacetime. The infinite mass and therefore gravity make a ton of sense in that scenario. That means they would be connected somewhere else. Possibly even not somewhere in our universe or maybe even dimension
Black holes don't have infinite mass. They have large mass contained in a small volume, which gives them a point of infinite density, while still having a finite mass. I agree that they can be visualized as stretching the fabric of 4D SpaceTime until it punctures a hole into 5D SpaceTime where they connect to all other black holes, and I believe this energy is what caused the Big Bang, since there's no law of physics saying that Time has to move "forward only" through the higher 5D SpaceTime. So the energy "lost" through black holes is what created the Universe that created the black holes, forming a giant 5D loop. Does that make sense?
Brilliant, as always! What a joy to learn!!
If their claim, black hole growth is coupled with the expansion of the universe is true, then could they potentially figure out a way to calculate the vacuum energy density using this idea helping prove their theory? For example, by using Hawking’s equation for black hole entropy they could try to relate the vacuum energy density (VED) to a black holes surface area in the formula then rearrange the formula to come up with a new prediction of VED and see if this matches observed values.
Yes, I was wondering about Hawking Radiation.
I often envision black holes tugging at the fabric of spacetime and spacetime like auxetic quantum foam. Look up a video titled "Auxetic Foam Research at HPMI" to see what an auxetic foam sample looks like. If the connection of black holes with dark energy is verified, the warp drive would have to be revised. Dark energy is said to be basically antigravity. It's something important for interstellar travel in reasonable time.
Excellent as always. Fascinating topic.
Wow The universe is big, complex and not understood. Good stuff. ❤

Super fascinating, I'd never heard of this!
I heard from another video about this paper (Anton Petrov, I believe) that black holes “swallowing negative energy” is effectively the same thing as producing dark energy as we think of it now. Could you comment on how black holes eating space itself could lead to space expanding? Thanks for the awesome content!

Could black holes manifest as dark energy by pulling spacetime inwards? Pulling spacetime inwards towards centers of mass could have a similar effect (or similar appearance) to spreading the voids outward... stretching spacetime out in the center, rather than the empty/void space having negative density.
Love the channel!
Just wrote this comment myself!
That's a neat idea for sure. But to me (a complete layperson on this stuff) that sounds like the empty space between galaxies is homogenous and unchanging, which would imply the amount of redshift of light from far away galaxies shouldn't be dependent on the distance it travels across space.
In other words, galaxies far away from us (and of similar size) would have roughly equal redshifting no matter the distance - because only the space close to galaxies would cause redshifting. And as for larger galaxies with stronger black holes (which results in stronger pulling of spacetime), we would expect to see more redshifting for those larger galaxies.
But again, I'm not an expert by a long shot and might be missing something.
@Danny DeWario if there is more distance to an object, then there more area being stretched by black holes between here and there.
If every black hole is pulling space in (causing the light traveling through it to stretch) and there are more black holes stretching space between a more distant object than a nearer object, the redshift would correlate with distance.

"People love to imagine things that they don't understand are somehow connected to each other" Me, that's me, I'm people.
lol, I'm so happy for you 😊
I'm atheist and very skeptical in general
@Mark Muller Just stay open-minded, fervent about finding the truth, and willing to accept it if you find it, even if it negates everything you may have previously believed.
@BackYardProphet You're contradicting yourself, being skeptical and atheist means not holding any kind of belief
Edit: Your name explains everything I guess
@Mark Muller Yea, you'll probably grow out of that by the time you are 30 kiddo. I found it an awful lot easier to be an atheist in my 20s when I still thought I knew everything 😁👍🏻
I think its still a good way to start thinking about dark matter. It could just be matter distorting light in such a way that our instruments cant pick it up.
Or something to that effect
Very well put, and I also like the skepticism!
Why???
Vacuum energy is very interesting. My thought is that "dark energy/matter" has always been related to black holes.
The thing that amazes me is that there is a answer to all our questions we have about the universe.
A question: many supermassive black holes we have seen are way too large considering the time they formed, especially those within a few hundred million years after the formation of the universe. We know that dark matter is affected gravitationally - could it be that black holes consume dark matter, along with regular matter, and gain mass that way?
i really love when Matt changes his cadence going into the ". . . Space Time" outro
This wasn't a good one for the outro
That's the one thing I hate about these videos.
Thats the one thing i get in these videos
I have had a silly idea in which I imagined electrons being remnants of blackholes... But thank you for sharing.
We often see black holes depicted in 2D models as the singularity pulling down spacetime. Are there any good videos that discuss how black holes actually look in 3D? Like is the BH actually flat and the horizon could be on plane with our POV / seen at different angles? Or would it look more like an orb? Like if a BH is facing us where we are observing directly above the event horizon in the 2D model, how far does the singularity go down? Wouldn't it run into other things near it?
You can see the black hole in 3D in the movie Interstellar. There is a gif of how spacetime curves towards the inside of an object's center of gravity. You can imagine gravity as the concave curvature of a contracting vortex and dark energy as the convex curvature between galaxies.
Absolutely. The distance between black holes is increasing from momentum, and being the strongest gravitational masses in the universe, by far, they pull everything along with them in their expansion. Next, you might find that the expansion of space between black holes might be faster than the expansion of the surrounding universe, because they don't pull everything in at the same rate as they are moving away.
Thank you for this beautiful summary of the background. I find some analogy between this idea of equating DE to SMBHs, and OTOH a quip I came up with a dozen years back, in the form of the bold assertion that _Dark energy is ambient pollution from alien warp drives!_
-- with diverse motivations ranging from the humorous take on Fermi's Paradox; through an objection made to a subliminal perception (likely to be widely shared) that the focus on uncovering some Earth 2.0 that's expected of exoplanet research, was premised on a secret project to escape by relocating there (rather than address) a self-inflicted destiny of runaway greenhouse effect attributable in good part to vehicular emissions; to a more direct if vague analogy between _accelerating_ expansion and _runaway_ greenhouse effect; and, finally; to alluding to the idea that _the negative gravity (and negative self-gravity!?!) of the massive amounts of negative mass-energy postulated to enable FTL Alcubierre drives, leads to expect that in case of a leak or loss of confinement, the negative mass-energy would in fact race to mimic the uniform distribution and influence currently attributed to dark energy._
I'd concede however that the satire directed by this quip at the expectation of our relocation to some Earth 2.0, is at risk from Poe's Law. A picture emerges of a Universe polluted by the failures multiplied over eons, of desperate attempts of planetary civilizations to save themselves using unstable approximations to an Alcubierre drive...

Very good sir, thanks for wonderfull journey into my imagination. You guys are inspiring 🙏
Ive been watching these vids for a while now, i appreciate Matts breakdown into simple terms on the subjects even if sometimes i dont fully understand them
A good way to think of this would be circulation in the body, but not arteries and veins, but instead both of those opposite the lymphatic system that balances pressure imbalances from the former with the rest of the body indirectly via an almost hidden medium of vessels. Likewise, as Black Holes concentrate matter, they might well be exerting opposite outward force in all directions, or possibly converting matter into space itself.
I like this «converting matter into space itself», black holes as spacetime factories, because stars are said to fuse simple to more complex atoms, and denser stars are made of simpler elements, like neutron stars, it makes some sense to me that black holes make quarks stop being particles and go to be virtual particles, such as are said to sprout and annihilate from quantum foam.

Could cosmological coupling be a kind of quantum entanglement, along the lines of ER=RPR, where the great voids from which space expands outward are essentially white holes?
I have speculated for years that dark energy is just another perception of black holes consuming space itself. If all black holes consume space, they cause a stretching of the spacetime between them and would be responsible for the primary red shift of measured galactic movements.
If you consider the 'rubber sheet' analogy, then it would make sense that if you have points on that sheet that are pulling in the sheet, then the points would increase in mass due to the 'sheet' they absorb and that the 'sheet' in-between would become stretched and give the impression of expansion. Over time, as the points increase in mass, they pull in more sheet, giving the impression that the expansion is happening faster. To someone living on the sheet, the difference between expansion and sheet removal would be very difficult to distinguish.
And of course, if the sheet is being pulled in at a constant rate, it would also explain the rotational velocity discrepancy in galaxies, thus explaining dark matter.
Interesting and creative analogy! But, the black holes are not the only ones that are consuming the fabric of space-time, so to speak, also ordinalry mass object, like planets, stars, etc., are doing the same thing, just that the intensity or "speed" is order of magnitude lesser that of the black hole objects.
I often envision black holes tugging at the fabric of spacetime and spacetime like auxetic quantum foam, and black holes as factories of spacetime, turning matter into virtual quarks, because stars are said to fuse simple to more complex atoms, and denser stars are made of simpler elements, like neutron stars, it makes some sense to me that black holes make quarks stop being particles and go to be virtual particles. And gravitational waves, and matter that is converted into gravitational energy, contributing to the expansion of the universe.

Thank you very much for doing the "What If Black Holes ARE Dark Energy?" video, this was something I had explicitly requested on the Discord back when that idea was published.
I've been binging on this and other channels to help me digest information about physics at which I'd otherwise shrug my shoulders. I sometimes find it easier to comprehend things when I don't get lost in the minutiae, and this sort of content helps me with that (I think).
I still struggle with dark energy. My brain keeps telling me that black holes contain separate universes. We know mass and energy from our universe can pass the event horizon and theorize it becomes incorporated into the singularity.
If there lies the possibility that our universe is nested within another, where our universe exists within a black hole in a parent universe, is it not possible that dark energy is fed into our universe as our parent universe feeds it matter and energy? Is it not possible that dark energy is the parent universe's matter and energy that fell across the event horizon following the instant our universe was created? Perhaps the mass and energy from our parent universe is not wholly compatible with our own universe, but continues to fall through and be present, regardless, contributing to our growing universe? Or perhaps that the information stripped from mass and energy falling into the black hole that cannot bear our universe's physical laws is damned to an existence at the threshold of the event horizon to be rejected back into the parent universe as Hawking Radiation or something along those lines? Would the feeding of mass and energy across the event horizon not lead to one or two inevitabilities: the universe that is being fed would have to expand in space and/or grow in density?
But I'm also struggling to comprehend merging black holes if they, indeed, do contain separate universes within? If the universe within one black hole has different physical laws than another black hole with which it collides and merges, would the resulting merger produce a unified universe from the mix of the two physical environments or would the universes merge in such a way that the physical laws for each incorporated universe allow them to both simultaneously exist within the same space, only interacting through compatible physical laws?
I'm in way over my head, but this stuff is so fascinating!
The unreliability of intuition is why we developed the scientific method. 😄
Just imagine the mess we'd have made of quantum physics without science, given its profound counterintuitiveness.
Matt links to a video by Dr. Becky, you should really check it out! If you like it, she also has good explanations on dark energy, etc in other videos.
Re: multiverses, etc. Remember these are mathematical constructs created by following mathematical theory. A "universe" is a set of numerical values on one side of an = sign. Multiverse theory is the logical conclusion of following the math that was used to define that "universe". So most of your yes/no questions are answered "depends" - they depend upon the values used to formulate the original mathematical universe.
I really want to read your replies in full, but for sole reason whenever I try to "read more," I'm directed to this reply. 😢
Thanks for helping direct my curiosities, I can at least see that I should check Dr Becky's content.
Must have been a bug. Got to read the full contents after I replied. Thanks!
I often envision black holes tugging at the fabric of spacetime and spacetime like auxetic quantum foam, and black holes as factories of spacetime, turning matter into virtual quarks, because stars are said to fuse simple to more complex atoms, and denser stars are made of simpler elements, like neutron stars, it makes some sense to me that black holes make quarks stop being particles and go to be virtual particles. And gravitational waves, and matter that is converted into gravitational energy, contributing to the expansion of the universe. Look up a video titled "Auxetic Foam Research at HPMI" to see what an auxetic foam sample looks like. If the connection of black holes with dark energy is verified, the warp drive would have to be revised. Dark energy is said to be basically antigravity. It's something important for interstellar travel in reasonable time.
If dark matter is made of stuff, suppose it is an undiscovered particle for instance, is it possible for a black hole to absorb it into the event horizon? Would that change the mass of the black hole? Would it grow? Could this effect explain the very large rate at which supermassive black holes expand?
The only thing we know about dark matter is that it interacts gravitationally.
Anything that does so becomes part of the black hole once it crosses the event horizon, and adds its mass/energy to it.
There has been an argument that since dark matter doesn’t seem to participate in electromagnetism, it would have a hard time accreting efficiently, since unlike ordinary matter, it cannot loose velocity and any orbital angular momentum by blazing it away quasar like in an accretion disk.
@Richard Classey yeah, that makes sense. I wonder if it would be possible to measure how much dark matter falls into a black hole and if that could tell us something about it. That seems a little out there though.
Dear brothers and sisters,
I have published a series of papers (totally 9 nos.) on "Theory of Singularity"
[Volume 10; issue 03,04; 2023] - arcjournals - International journal of advanced research in physical science - Open access for free download.
1) New representation of Gravitation
2) Structure of black holes
3) Finite structure of space-time.
4) Real dimensions of space-time
5) Singularity
6) Source of dark energy...etc
"Fundamental theory of Singularity" - The new proposed study that serves one fundamental for general relativity and quantum mechanics by solving the incompatibility between them...thank you
Imagine if we in a couple of years actually figure out what dark energy is and it turns out to be embarrassingly obvious to have missed until then...
If local space time looks similar, does it look less similar on the edge of a large galaxy's space-time? Would dwarf galaxies at the edge of larger galaxies be affected differently than the ones closer in and could you glean anything interesting with that boundary region?
It would make sense that if space is expanding in all directions from everywhere then massive objects would also expand.
Hi Matt
I greatly appreciate your work.
I was wondering if you can check out the new cosmology theories of Mohammad Ali Taheri around dark matter and dark energy and more and let us know about your thoughts
Here is the name of the video
4- Dark Matter, Dark Energy & Space Viscosity - A Theory by Mohammad Ali Taheri
There are more videos in that playlist they are very interesting
Thank you
I've thought of a similar situation. If our Universe is indeed 'inside' a Black Hole in a parent universe, the rate at which that Black Hole consumes matter determines the strength of Dark Energy and the rate of expansion of our Universe. A Black Hole that is consuming almost nothing would mean that the universe inside it would have a very slow expansion, while one that is feasting on a star would have a much faster expansion.
I guess I'm implying that the Hubble 'Constant' is not constant, but depends on the amount of matter falling into our 'parent' Black Hole.
The hubble constant is already not constant. It's really the "hubble parameter". It is only constant across space(as far as we can tell), not time because the expansion rate changes with density.
So if Dark Energy does turn out to be created by black holes would that mean its just a measure of how much spacetime has been stretched since the beginning of the universe by massive objects?
Maybe. I often envision black holes tugging at the fabric of spacetime and spacetime like auxetic quantum foam. Look up a video titled "Auxetic Foam Research at HPMI" to see what an auxetic foam sample looks like. If the connection of black holes with dark energy is verified, the warp drive would have to be revised. Dark energy is said to be basically antigravity. It's something important for interstellar travel in reasonable time.
Would attributing the mass of black holes to dark energy change the distribution of the masses in the pie chart (matter vs. dark matter vs. dark energy)?
I've said this years ago on this channel, but I think dark energy is essentially just the part of gravity we haven't figured out yet. And if we can get the shape of black holes down (you know, get rid of the singularity in the math) then we may immediately get an answer as to what's causing dark energy.
While this study has me far from convinced of their conclusions, I do like that they used that very idea to get here and I hope more do it.

i'd love to review the data pools that lead you guys to the conclusions you reached
"A black hole only knows about what falls into it" in my head became "The black hole knows what's inside it at all times. It knows this because it knows what isn't inside it."
Would it be mathematically equivalent if everything in the universe would shrink at some rate over time, proportional including the strength of the force field? And time dilation included, this would just not be as dramatic for black holes so that they seem bigger to us over time?
I feel like this could make sense if we flip the idea 180° once or twice.
This paper sounds like a strong case of "having a conclusion before making the experiment" to me.
Yeah like which publication
"Come up with a theory that explains a thing, design experiments to test that theory, and record the results" are the basics of the scientific method, but another, just as important, part of the method is "rigorous adherence to honesty in your experiments and the willingness to accept when your theory is flawed."
@Derek Floyd But wait, the theory is "99.8%" non-flawed! Close enough for jazz, as they say. And cosmology evidently.
I had the same response. The idea that old galaxies should have smaller black holes seems weird. Assume a galaxy that does not accrete more mass. Over time it’s black hole should increase in size. Which would make “black holes grow faster than their galaxies”
Or just testing for correlation? It doesn't really say anything else as the space of explanations for that correlation (and all scientific explanations/theories-other-than-equations) is infinite, and we generally just use Occam's razor with no deductive logical basis to use it, sometimes more complicated explanations are the correct ones (though in the case of simplified models, it's more precise to formulate Occam's razor in terms of number of assumptions, and simplifying assumptions are assumptions)
If two particles can become entangled by placing them very close to eachother, then is it possible that all of particles, under the immense gravity of a collapsing star, reconfigure into a wave function as seen in entanglement?
The entangled particles are said to in fact form a wormhole. The black hole would form a wormhole with a white hole from a big bang of the universe that it contained within.
What I'm hearing is that dark energy and thus black holes are actually the friends we made along the way.
Best show on you tube for years straight. Keep it up Matt!
Fantastic video, Space Time team!
Great episode - love hearing you comment on other people's papers.
Thank you for making a video on this. I have talked about this subject a few times, so its nice to see it being covered.
You should check out the video he suggested, Dr. Becky is just the best when it comes to black holes, and she gives them an even fairer review than Matt
This is The topic I have felt may explain what so many are looking for.
Great discussion and If anyone is able to crack this problem I wouldn’t be surprised if DE Is coupled to galaxies and black holes. But this problem is the size of the universe so there’s that. Good luck. I’ll be watching.
For me I think it’s fair to imagine the same amount we know about black holes equals roughly the same amount we know about dark energy. Great team to push new ideas. They must align with the old rules but new discoveries make new rules. For me it’s the elephant in the room that black holes are what keep our sun orbiting around the Milky Way, keeps the earth spinning and set to motion the weather even.
The idea that black holes are dark energy raised a question in my mind about dark matter: If it is five times more prevalent than ordinary matter and seams only to interact with gravity, are there very dense areas of dark matter i. e. dark matter "stars" or even "galaxies"? Obviously we can't observe them directly, but shouldn't they be visible via gravity lensing?
Would black holes gaining mass over time, all over the universe, cause an increasing tension on the fabric of space that would look to an observer within that universe as if other objects seem to be accelerating away towards their cosmic horizon? An increasing, uniform pull from outside our cosmic horizon, rather than a push?
I'm hyped you're doing this video. I'm interested in this theory.
Been looking forward to this video since the paper dropped. That was quick considering all the animation and editing, thanks spacetime!
thanks spacetime, for everything you do
Wouldn't it be funny if after all the work and math put into trying to understand dark energy and the expansion of the universe, we ended up realising that the universe is actually staying the same size but all the stuff inside it is just getting smaller so it looks further apart.
Hi, I was thinking about the same fact 2 years ago but I thought what if black hole is made up of dark energy as black hole and bark energy attract objects towards them because of their density, so I just had an idea about it and I am not sure is it right or wrong. What is your opinion?
I don’t understand most of what he talks about, but I’m addicted to listening to it and trying.
Thanks for the great video! I was wondering how black holes and dark energy could be actually the same, since black holes clearly have a gravitational effect on the surrounding matter and should though counteract the expansion of the universe. I'm a chemist, not a physicist, so maybe I missed some fundamentals behind that idea.

"People love to imagine that things that they don't understand are somehow connected to each other."
This explains so many behaviors! I'll keep this in mind from now on.
Wouldn't the rate of expansion then depend on the local density of black holes? Then some regions of the universe will expand faster/slower than others.
On the largest scale matter as well as black holes should be equally distributed.
That was my exact question. That changes the shape of the universe making the visible horizon different in every direction. Meaning no more Hubble constant.
Not necessarily. Depends on the underlying physical mechanism by which the black holes convert mass/energy into space. If it's something like water pouring into a bathtub, then well, the water level rises uniformly even though the source is localized. This analogy is stronger than one might think - fluid dynamics equations are suspiciously similar to GR, both of which treat the subject matter as a continuous medium - even though we KNOW that water is NOT continuous medium, it's made of particles.
Or better yet, imagine a tiny stream of water falling onto a kitchen table, slowly growing a pool.
@Emp Empischön Fair enough I didn't read the paper so I'm a bit unqualified to even ask a question. Yet this is the second video on this subject I've seen in as many days. I would love to explain dark energy this way, but it just seems way too hiding in plain sight to explain such a confusing and complex subject. So I guess I'm looking for that steel toed boot to kick it in the head.
Thanks for your explanation it does make sense considering what is expanding is all part of the same single fabric.
@Emp Empischön I know that this is all conjecture but I like to imagine that space is an emergent property of mass / energy and that as it expands, it has to push against the surrounding spacetime, causing it to compress, causing what we call gravity. This expanding space still has to go somewhere and that's we observe at larger scales, i.e. cosmic inflation.
What makes black holes unique is that the space is expanding faster than light can travel across it and any light that enters is basically red-shifted into oblivion.
By no means do I have a grasp on all the theories and physics behind blackholes, but has the subject of blackholes containing or giving birth to universes been touched on recently with more theories and data to date? Would be a nice 'what if' to rip apart or explore in a nutshell.
That innocent sounding phrase, "That may one day be detectable," pretty much kills of it.
Nonetheless welcome a change from the more SF oriented episodes that we've had recently.
If I understand this, wouldn’t this suggest that the universe’s expansion would be variable based on the distribution of black holes? So unless supervoids were filled with black holes wouldn’t supervoids expand slower than the rest of the universe?
I’m very curious about the potential relationship between this coupling and entanglement. I know I understand neither which is exactly where this discussion came from, but I wonder nonetheless
I love how we have dismissed the Aether but are now on the lookout for dark matter and dark energy! 🙃
If ER=EPR, could that provide a mechanism for cosmological coupling to work and provide a solution to the even distribution? As in, all supermassive black holes are connected to each other via wormholes, which provides a way of ‘sharing information’ on large scales and smoothing out the distribution.
So how would a black hole, with such a powerful inward gravitational pull, also push space away/ expand it outward at the same time? If anyone knows what the explanation is, I would be interested to hear it. 🙂

Nothing wrong with people loving to imagine things they don’t understand
I’ve been saying for thirty years that the only thing that can go through wormholes is space. If these massive black holes are wormholes to the white hole at the start of our universe, then it makes sense to me.
If you look at the vacuum energy as the lowest possible quantum energy density, then it's just another one of those spooky actions at a distance things isn't it? If that was the case then you could start thinking about the role of dark energy in quantum entanglement.
