I’ve been pondering for many years that space time is the “glue” holding the universe together. Black holes eat space time. Less space time means less glue and the universe gets bigger. Since the universe is a bubble of space time, mass, and energy the outside of the universe must be no space time, and zero values for mass and energy. So it naturally wants to expand but that the glue acts to hold the bubble together.

I studied degree level physics over thirty years ago and always thought black holes might have something to do with the expanding universe. For me this is an exciting development, great time to be alive.

I thought that listening to PBS space time, the larger the mass the larger the impact of its gravitic field which would cause expansion of orbital range, which would drive wider ranges. As a complete non educated I've watched a lot of stuff like this and I honestly think both of them are just 'gravitic effects'

In a half asleep dream imagining, I pictured this: Blackholes not only Frame drag the "grid" of spacetime around in a kind of torque, they also Frame SUCK the spacetime inward as well. So the expansion of spacetime is the pulling of the 'sheets' down each big black hole- so the 'grid' between black holes gets stretched, and thats the redshift we see, as opposed to any actual expansion.

I had this idea for years. Since the observable universe is just a tiny part of the entierty, the cumulative effect from the sum of all black holes (majority of which are outside what we can observe) would create an effect that, when observed from our cosmological bubble, looks like expanding space. I do not have access to a theoretical physicist to tell me how is that idea wrong and I am sure it must be right? Since the idea is so simple, I'm sure they thought of it, and then discarded it, otherwise it would be mentioned somewhere...

That’s because what he described wasn’t hawking radiation. It’s the common depiction, but actual Hawking radiation is more complex. A more accurate description of Hawking radiation (as I understand it from other videos on the topic) is that the event horizon cuts off certain vibrational modes in the quantum fields. This means that the fields cannot be in their respective vacuum states, and so to restore them, particles effectively pop into existence with the necessary vibrational modes to restore the fields to their natural state. The particles produced are random (i.e. not limited to only photons) and have a wavelength of the event horizon’s diameter. And in order to get away from the black hole the particles effectively steal energy from it or the space around it, thereby reducing its mass. Also, because of weird relativity stuff, an observer close to the black hole will not see any particles, but an observer far away could.

Seriously, it's a common misconception that they're both particles and waves, but it really is just wavea, and localozed highly stable waves. Quantum fields need an exact amount of energy to generate a "particle". But quantum fields do SO MUCH MORE.

Their approximauoms of the continuous fields actually doing the work. Even empty fields all have a non zero rest energy thanks to the uncertainty principle. I'm getting there, don't worry. Think of a quantum field as extending drln one "end " of the universe to the other. Now, put a black hold in the way. Because quantum fields are are always shaking, they always have some wave activity. When put a black hole in the way, it literally puts a hole in the field. That really disrupts the field, and certain frequencies or modes (loose analogy) become impossible. Because quantum fields are everywhere spacetime is, they are inside the black hole too. That should help you visualize how energy can leak from the black hole. A mode is the quantum field behavior when it is disjointed in some way. The field essentially freaks out. It creates an effect in the electromagnetic quantum field. While part of the field gets trapped in the black hole(sorta), the uncertainty principle allows radiationto sometimes exit. Mass is responsible for the modes, so as radiation leaks, it takes some of the mass with it.

Actually I have a better analogy. First understand that particles are essentially just fancy vibrations in their respective quantum fields. A quantum field is a bit like a drum skin, it has a kind of tension so when you give it some displacement it oscillates around the equilibrium. When you hit a drum you create ripple like waves that travel in all directions across the drum skin. If the drum was very large or even infinite, the waves would travel away just like ripples on a pond. But when the waves hit the edge of the drum, the skin is pinned down, it canno5 vibrate. This is called a boundary condition and the waves will reflect off the boundary and interfere with themselves. Depending on the wavelength of a given way and the size of the drum, some frequencies will interfere with themselves destructively and cancel out while others will have just the right frequency to interfere constructively and form standing waves. This is completely analogous to an electron confined to an atom. The electrostatic attraction between the electron and the nucleus is like the boundary of the drum skin. It restricts which frequencies are allowed for the electron wave, hence atomic energy levels. The event horizon of a black is similar, except it affects ALL the quantum fields at once. It restricts which vibration modes are possible within its vicinity, and that means different particle states are allowed compared to a normal vacuum. Basically, if you put one finger on the drum skin and then hit it, the sound is different, muffled. Your finger is the black hole. The frequencies that make up the sound are the different particles. Roughly speaking.

I knew this intuitively since I first heard the terms " dark energy/ dark matter".

Thank you for producing this video. 7:00, my understanding is that a neutron star/black hole is not produced by the force of gravity in a supernova, but rather due to implosion. The explosion is extremely powerful, but there is a medium point in the star where the matter just cannot escape fast enough (i.e. explosion), so the forces causes matter inside the medium point i.e. the core, as said, becomes a neutron star or, if more mass, a black hole.

This has been my own theory on the universe, which is that black holes are recycling machines, breaking down matter into its most basic form and spitting it out back into something that becomes nebulae, stars, star systems, galaxies, and once again black holes.

Thanks. Very interesting. It is perhaps important to keep in mind that light [EM radiation of all types] does add energy density to a black hole. So it would seem that, even if a black hole isn't actively feeding, all the EM radiation out there would still increase it's size / mass. Witness the Kugel blitz. Over billions of years this would (presumably) add up. Of course, other things could be going on, too.

How much, does light pressure (photon-impulse transmission on everything it hits) account for the expansion of the universe? Isn't vacuum energy just that light pressure around us? ( I recall that idea about two parallel plates being so close that light can only push from the outside of the plates) The black holes being the engine of space time makes even more sense, when you take the viewpoint from the universe (itself not expanding) where everything inside (galaxies to the rulers) is shrinking.... caused by black holes.

I came up with this idea myself about a year ago or more, though it wasn't as fleshed out and I did not really have theory or evidence to back it up. I think I may have even left some comments on some videos about it the idea of the two being connected.

Nice summary. Two things I take from this. k is close to pi... could the error bar on this 3.11 move up? If the black holes are some how creating DE, then it would imply that there are spots in the universe that aren't expanding evenly. Could this then explain the cosmological crisis?

My sis and I have always only thought of this as the conclusion, but now that its with us... it almost feels like there should be more it.. this just can't be it

This result reminds me a lot of Leonard Susskind's ideas about ER=EPR. If the Einstein-Rosen Bridge leading from the event horizon to the singularity is expanding as the black hole ages, then this created spacetime in the neck of the black hole would contain the same vacuum energy as in the rest of the expanding universe. In other words, rather than black holes' increasing mass being the cause of dark energy, might this instead show they share the same cause: vacuum energy?

For quite a few years I've hypothesized this as well that the expansion of the universe is also likely responsible for our direction of time. Entropy being how we reconcile the direction of time but the expansion of the universe is also intrinsically entropy anyway so it would make sense that the expansion/entropy would be affected by gravity. Black holes having an effect on both of these makes sense, furthermore Black Holes would also be linked and reaching back to the Big Bang in the singularity giving birth to the only white hole.

I'll need to look over the theory and methodology before I'm convinced by the larger cosmic effects, but it's an interesting theory to me because it might help explain how superlative black holes themselves form. We've yet to completely nail down a mechanism that could produce such large black holes, especially when they seem to already be around really early on as well.

I happened to read this Farrah et al. observational paper on the same day as its online publication. I emailed Farrah that evening (never getting no reply) that a more likely theoretical explanation would not be that black holes trap dark energy WITHIN, but rather that they likely RADIATE dark energy outward while absorbing positive energy inward from "splitting the vacuum" near the BH horizon. My theoretical paper, first submitted to ApJ in the last week of February, was nearly identical to the one I published today (4/18/2023) in Journal of Modern Physics (also peer-reviewed), entitled "How Dark Energy Might Be Produced By Black Holes". It attempts to tackle the possible mechanism in a way similar to the Hawking radiation approach, only with the energy sign of the absorbed particle reversed ("positive" rather than "negative"). Accordingly, this would allow ASTROPHYSICAL black holes to GROW in mass-energy while radiating negative energy into the outer vacuum. I refer to this novel mechanism as "black hole dark energy radiation." Naturally, more observational data is necessary to sort these things out, but my approach, based also partly upon Dirac's mathematical formalism and FSC, has a nice symmetry to it. Important advances in physical theories often do. Sometimes the gatekeeper journals are slow to recognize important new ideas. I wonder why? Perhaps E.V. needs to take a rest.🙂

Current theories already strongly indicate that the singularity of a blackhole, is not a place but a point in time, supposedly infinitely far in the future, but more likely just a point in the very, very far future (~10^120 years) if the singularity never shrinks beyond planck length.

Same idea here. If dark energy is not uniformly spread out over all of space, but concentrated within black holes, we can assume that the rate of expansion of space is dependent on distance - further away, less space expansion. It means that stars further away from the black hole have less "work" to do to overcome the expansion of space, hence they will show up as moving faster then though. Perhaps also, the gravitational constant is dependent on distance from the black hole (and time).

Great explanation. After listening twice, I almost feel I understand it. But it's totally mind-blowing to contemplate. As mass accumulates, the universe expands as if the black holes' masses is somehow related to the expansion. Possibly even the cause ??? It doesn't seem like there could be a mechanism ... could there be a way to understand it at all? I imagine this could lead to the expansion of our understanding of physics if it is something that is knowable by humans.

1. What exactly is 'space' and how exactly does space expand? 2. What exactly is 'time' and how exactly does time vary? 3. What exactly is 'gravity' and how exactly does gravity do what gravity does? 4. How exactly do numbers exist in this universe for math to do what math does in this universe?

That's very interesting! Very strong correlation to ignore! Not to remind that correlation on its own doesn't point to the direction of causation (if there IS causation at all). But what I'm wondering is regarding the "source" of Dark Energy (DE). From other videos on the subject I understand that DE actually manifests in the vast empty space in between galaxies. And in the scale of a galaxy or a stellar system it's too weak (compared to gravity) that it can't pull anything apart, only makes galaxies move away from each other (unless perhaps they're in a denser galaxy cluster?). My point is how would the largest source of gravity (attractive force) inside a galaxy be the source of a repulsive energy outside of galaxies?

Cool!

Universe seems to expand in the huge voids between galaxy clusters where almost no regular matter is present... Also interesting to think what really means expanding space(time).... If spacetime is quantized what happens ? New quanta of space are created between the existing ones ? If not do it simply stretches itself ? Dr. Carlo Rovelli in one of his books wrote: "Gravity IS spacetime". That to me has some deep meaning...

As a particle physicist it is logical to see a particle behind a coupling. In a talk Prof. Tiziana di Mateo stated that supermassive black holes stop to grow, which means that also dark matter stops to fall in the black hole necessitating a dark radiation pressure. I assume that this is created by light particles, created in the collision of heavy dark particles as they fall towards the black holes. If they are neutrino like, they could permeate the universe with a dark flow that weakly interacts with dark matter, creating the pressure to accelerate the universe. Dark energy would then be the gravitational force of all the black holes in the universe. The problem with this idea is that the actualy estimated mass of all black holes together is way too low, but who knows.

Re the hawking radiation - the growth of both at the same time is probably the imbalance caused by them eating 1/2 of entangled virtual particles. Another interesting thought: Maybe this reinforces that we're "inside" a black hole.

Good question, I'm not sure we have the answer at the moment. Generally, we consider the local gravitational environment to not be expanding, and the instead the space between galaxies to be widening.

I think the interpretation of how this mechanism is actually working is the important bit, and I'm not sure we understand that at the moment

Another possibility assumes inflation actually happened. The big bang process spontaneously created black holes where spacetime literally tore open due to the extreme rate of expansion. The energy in the big bang would have been more than enough to create such rips in spacetime. No mass needed, just energy which resides in the extreme curvature of spacetime. As these black holes would have gulped down gargantuan amounts of energy due to the extreme density, dark energy would have gotten a start boost, fueling inflation until the universe was large enough that black holes became limited in their consumption. Just thinking from the top of my head here, love to hear counter arguments to shoot this hypothesis down.

Does this have any impact on the theory for Dark Matter to explain how many galaxies behave? Specifically if these galaxies that need dark matter to explain their behavior have a massive black hole at the center which is the source of Dark Energy, does this also have an impact on how these Galaxies behave?

Well... by E = mc², perhaps, just perhaps, that effect is conveyed by particles. So that may not be too far off.

I have a crazy idea. What if Black Holes contract the space around them somehow making each galaxy contracting in relation to the rest of the universe. Wouldn't this give you an expanding universe where pockets of mass(galaxies) stay roughly the same size to each other but shrink in relation to the rest of the universe. Although this wouldn't explain why galaxies with bigger black holes in the middle don't "contract" faster. But hey... It's an idea. O_o

Interesting theory but i have a question for it. How would the universe expands in it's early ages, before any black hole would apear,or even after a few apear in some galaxies ?

I've been predicting this for the past 2 years.

Could it be that the universe we observe is like a common channel for the singularities in black holes to transfer energy from mass consumed by black holes?

Are we sure the black holes themselves are the source of the universe expanding, or are both just subject to the same process causing both the universe and black holes to grow/expand? Why would one conclude this correlation is causation? I don't see the evidence for jumping to that conclusion.

All the paper showed is that the growth of black holes is correlated to the accelerating expansion of the Universe, measured by redshifting. To like 5 sigma. Correlation is not equal to causation. Correlation between A and B can't discern if A causes B, B causes A, or both A and B are the result of unknown C. This basic misunderstanding of scientific statistics causes a great deal of chaos once research leaves the Ivory Towers where they keep most all the humans trained in both statistics and the scientific method. Nowhere is this chaos and confusion worse than in "medical science".

What would seem to be weird about black holes causing the expansion of the universe would be that it would effectively kill black holes on a universal time scale. Since black holes require matter to flowing in to continue existing (assuming hawking radiation is actually a thing), by causing the expansion then eventually the distance of matter from black holes it would eventually lead to the black holes evaporating. This would then cause rhe “bounce” to occur or cause nothing to exist.

I think inside all matter is locked in “dark energy” I think black holes vacuum pack this energy and redistribute it. But I also feel like matter in the physical dimension displaces dark energy like ice in a glass- same stuff but in a different modality. So same stuff but taking up a different volume. That’s what my heart tells me anyway 😂

Hey, good clip from the woody Allen movie

Ok, looking forward to their explanation for uniform lambda across all points of space, rather than varying by proximity to a blackhole. Something going on at the boundary rather than in the bulk?

4'40: They called it a dark energy by fear of saying negative gravity. If the big bang made this spacetime, it might as well have made an opposite spacetime (action/reaction principle), interacting with us only by a repulsive gravity. This would elegantly explain both dark matter (galaxies not being heavier than they look, but compressed by repulsion of the anti-spacetime matter which is around them) and dark energy (obviously, mutually repulsive interactions lead to runaway expansion). Who has heard of the Janus model?

Lovely floating droplet at approx. 5: 59 - thin layer of air separate the drop from the liquid.

This is probably the most interesting science video I've ever seen. So, if I understand it correctly, the expanding universe causes black holes to grow. Does this, in turn, cause the universe to grow further, creating a positive feedback loop? Does that mean that eventually the entire observable universe will be swallowed by an ever-growing black hole? That's kinda depressing. But then what causes the expansion of the universe in the first place? And how can black holes convert mass, with positive gravity, into dark energy with essentially negative gravity?

I'm attending a talk tomorrow by a Dr. Kevin A. Croker one of the co-authors of the paper concerning the mathematics of cosmological coupling of non-singular black holes

a word of advice to the editor... I know it is common in science to use the word expansion ... however...for the regular simple human...it means nothing... nada plz contemplate using: space expansion..or even better if use space creation i found so many who don't get it excellent video many thx

It is now thought that only a part of the universe is expanding as many galaxies are moving toward "the great attractor" eg it is predicted that in the future The Milky Way will collide or move through Sagitarius. The simplest explanation is that as galaxies orbit they may move away or come together in varying cycles.

Very interested to see the more evidence that black holes are coupled. Isn’t this sort of correlation not causation? I guess I’ll have to read the paper.

My first attempt at an educational path was in physics and the link between black holes and dark energy makes so much sense and has such a "truthiness" feel to it for me that this does not bode well for the hypothesis. My speculations for what scientists will find on the quantum realm is currently at 100% incorrect compared to chimpanzees randomly hitting yes or no buttons getting at least 50% right. I did find this entertaining and for whatever it is worth it all seems reasonable to me.

I've always wondered how spacetime could be falling into the center and stretching without being pulled from somewhere. I wondered if this could cause the expansion but I guess it would be uneven.

It would be wild if the black holes are converting mass into space. What if every black hole is doing this and we've only noticed supermassive black holes doing it? Major spitballing, if the black holes were producing more space directly, there would be a kind of conveyer belt working against their gravity

Probably, galaxies expand into space and space comes between them to balance the density of space between galaxies. And it shows that we are living in an island universe.

Dear Dr. ben Miles, By the Geometric Chronon Field Theory, if you consider that not only conventional mass generates gravity but also charge does with + generating extra gravity and - generating weak anti-gravity, the electrons that are accelerated to relativistic speeds and escape the galactic pull ,constitute what we call dark energy. On the other hand, the active galaxies accumulate + charge which cause a dark matter effect, e.g. the positively ionized hot gas of the Bullet Cluster. This charge falls into the the super massive BH and causes it to expand beyond the expected value by mainstream physics. See "Electro-gravity via geometric chronon field and on the origin of mass" in ResearchGate. It is much more correct than the peer reviewed version from 2017. Many errors have been corrected in the ResearchGate version and the it is beyond comparison more advanced. Kind regards, Eytan Suchard.

So if I understand it is that for normal and small blackholes their mass is radiated away over time due to quatum fluctuations causing Hawking radiation. But for super massive black holes, it consumes the quantum fluctuations?

So, if the universe is flat topologically speaking, black holes are just bends where matter from one side goes to the other? Dark energy is the resulting effect since at least one side of the universe is loosing mass and the other side is gaining. Is there any way for us to know what side of the universe we are on. The internal expansion or external surface?

Science-Fiction idea: Humanity tries to create artificial supermassive whiteholes to counter the expansion of the universe, but creates a world full of new physical laws. I've got no clue if this would be good. I was just amazed by the topic.

Interesting stuff. Here's my (probably bad) question... Assuming black holes evaporate (Hawking radiation, etc.) what happens in the far future when they all do? Does the universe stop expanding? Does the expansion stop accelerating or even slow down? Does it have no effect? Or is the universe so diluted by then that it doesn't even matter?

This is my Recursive Black Hole Universe Hypothesis: a black hole is a time-reversed white-hole, and our singularity was in fact a time-reversed black hole. The “rules” which apply across time (which are generally considered by physicists “fundamental laws” are parameters encoded on the outside boundary, but actually apply across the inside. What happens inside a boundary is that these rules are applied over time, which results in an emerging reality

There isn't any "but how" - not even remotely. Presumably, they're arguing that because the mass of a black hole depends upon the boundary conditions at infinity and for our universe we don't have asymptotic flatness at infinity but an asymptotically de Sitter spacetime at timelike infinity that this then implies a dark energy content of a black hole. However there is no such calculation and I'm wondering if I may be giving them more credit than they deserve. What it looks like, at least over a superficial reading of the paper, is that this is nothing more than them arguing that if these new exotic dark energy black holes exist, and if they scale up in proportion to the cosmological scale factor then when averaging the dark energy density over sufficiently large volume then the total dark energy density is a constant - but this doesn't tell us very much (and I may not be giving them enough credit in this case).

Surely… if these Black Holes are so much larger than the “old Galaxies” justify and the size can be explained by the 68% “missing component”… is this simply further evidence of vaccuum energy/ dark matter… which is being “consumed” by the old black holes… does this make any sense?

This actually changes something about the universe faith instead of just being empty in and freeze in a few googolplex years it's going to be full of light-year wide black holes

With an unblemished record of experimental failure to find anything remotely resembling Dark Energy or Dark Matter, we can now confidently link them together with black holes, a cosmic phenomenon the basis of which is pure gravitational math with no consideration to super hot plasma configurations. Cosmologists, full speed ahead!

do black holes gain mass from consuming the background neutrino flux?

So if we could somehow get rid of every single black hole in the universe, the universe would either stop expanding or start shrinking? That seems wierd considering the fact black holes pull stuff in rather than pushing stuff out.

Yes it would, but getting rid of black holes is probably impossible because of how the event horizon works. Even if you somehow had a weapon that could "break" the singularity at the core of a black hole, if you fired it, it wouldn't reach the singularity until the end of the universe. It doesn't matter if you have a magic reactor that can literally generate endless energy from nothing, powering a beam that could blow up a star with a mass a thousand times greater than the black hole. You can shoot the black hole, sure, but the beam will take quintillions of years to actually reach the singularity. And when it does, it just adds to the black hole's mass, because in a singularity there is literally no difference between mass and energy.

@@noneofyourbusiness2437 Unfortunately, I think that as far as we understand science, the white hole would only succeed in feeding the black hole and making it bigger. Basically, any way that you combine a black hole and a white hole of equal size, what you end up with is one black hole and one white hole twice as big. It doesn't matter if it's the second black hole or the white hole that you push into the first black hole, the effect is the same. That's assuming white holes are stable - recently physicists have suggested it is more likely that white holes would expel all their mass/energy at once due to the density being infinite. If that's the case, it is highly likely that a white hole was the cause of the Big Bang. In which case, good news! Our universe is producing billions of new universes. I mean, not so much good news for US, since getting to one of those new universes would require passing through a singularity, but good for whatever lifeforms evolve in those universes, if any.
