Somewhat I hope that these findings will turn out to be correct. The whole idea of dark energy has always seemed very unsatisfying to me. Looking forward to seeing what astronomers can find out.

Dark matter sounds perfect, now dark energy. You know the what they have in common? They still don’t have a clue. All I can say is I am grateful to Einstein, I didn’t know he stopped the universe exploding. That is RAD😂
But even if you ask something they are all up in arms against you, calling us stupid, unable to understand etc., etc. When in fact they are the ones who don't know despite spending so much time working on the same thing.
"Dark Energy" has always been a stand in concept, a label for an observed phenomena that scientist lacked a good explanation for. It's like knowing about plant and animal evolution without knowing about genes and epigenetics.
Exactly, that is an excellent analogy. The more we learn about cosmology and physics, the more "dark energy" as an explanatory concept fades away into a relic of science history.
I don't think it's that scientists don't challenge their own ideas, but that institutions tend to get locked into orthodoxy and certain ideas become "untouchable" until overwhelming observations force change.
Nonsense. Scientists constantly challenge ideas of other scientists, the issue is finding a different solution to the problem that fits better than the current idea. It's not orthodoxy.

@@KnightspaceORG We found thousands of stone vessels, made out of the some of hardest stones. They are all following a predictable, mathematical pattern. In other words, they have been designed (I let you imagine "something" that takes mathematics as in input and outputs carved stone...), the precision matches modern CNC machines. The catch? We found them under the stepped pyramid, the origin of their discovery is documented and not controversial. (we have CT scans, 3D models, mathematicians looked at them, electron microscopy, and metrology done on them. STL files are publicly available. All of the above is 100% factual) Anyone looking into this will conclude that we are not the first advanced civilization on this planet. Whoever brings that up will get relentlessly and ruthlessly attacked, defamed, and shamed. That's just one example. The unfinished obelisk of Aswan is hand-waved by scientists. It's 1,200 metric tonnes, we could lift it today, it would take 36 modern cranes, then the only thing you could do is put it back because with 36 cranes around that thing, you're not going anywhere. Egyptians made an even bigger, estimated at 1,400 metric tonnes. Where is it? We don't know, there's only the hole left.

Question that, you'll be attacked. Around the Spinx are wall, it's actually in an enclosure. The ground was excavated, the middle part wasn't and that's how the made the sphinx, 4,500 years ago, according to science. The issue? There is signs of tens of thousands of years worth of erosion on the enclosure. Question that... You know the drill... I could go on and on, it's gotten to a point that I believe that the most used tool in all of science isn't a microscope, a scalpel or a lab coat but shame.

It’s interesting how the preference for elegance and simplicity over messiness and complexity has at times led us to hold onto theories for longer than we should have. But this is how paradigm shifts begin, according to Kuhn. An alternative theory arises that better explains a certain piece of data. Then it begins to explain other observations that don’t fit into the existing model. At a certain point, the existing theory gets so weighted down with messy complexity (epicycles) that the new theory begins to seem more elegant.
The problem is that beauty won't go away, it just morphs into different parameters over time, it is too subjective and is preventing good theories to emerge because they don't meet the right beauty flavor of the time.
That’s sounds like what’s happened to the Electric Universe model. Except, it is older than the Big Bang… was and still is suppressed in favor of the current cosmological crisis. We can’t have a theory that includes electrogravitics when we’re also trying to keep the advanced technology to a minimum. 😉
So to recap, Timescapes is saying that due to absence of gravitational bias through voids it's causing a red shift that we mistook for an accelerating Universe? I mean... I really hope this is true for the future civilizations after us.
This doesn't necessarily mean the universe isn't expanding, but it does mean that the known models would be completely wrong about the rate of expansion if it is actually expanding, in theory though this does open up the possibility of a renewal of other universal ends like the big crunch because we wouldn't be capable of measuring alot of things properly at that point, even the age of the universe would be questionable if this is proven true.
It's almost right too, but it's not. I went through all the calculations a few days ago and the answer is simpler and much more intuitive and elegant then even that. Because it doesn't explain why the universe appears to be expanding at an increasing rate. It only assumes the cause of red shifting, because we haven't been able to prove why light red shifts at all. Only that it does and more so in objects further away. But the accelerating universal expansion thing requires space to be expanding, we can't observe that locally in any way at all. It's not the universe that's expanding but light is accelerating. It does so more absent the interference of gravity. So once the light makes it into intergalactic space it will continue to accelerate forever as the wavelength lengthens. The photon has no mass, it's simply a transfer of energy from one form to another, wavelength to velocity. But at that speed the light doesn't experience time itself. It is the distances that cause the wavelength to stretch out and increase the speed like a spring uncoiling. That is the only thing that explains why the universe looks like the acceleration of the expansion is real. It's the light accelerating, not the universe. It solves every mystery, eliminates the need for dark matter and dark energy entirely and makes all our observations make total intuitive sense. It even explains why galaxies rotations seem too fast to hold themselves together. I spent hours doing the math with an Ai double checking everything. It couldn't find any problems with it either. I had to train the model on the concept first, I wanted to know if I was missing anything. So we plugged the math into everything it might break and it all worked better. It only breaks the need for dark matter and dark energy. Which obviously don't exist and never did. Or we'd have seen them. It even won't affect our technology in any way. Light accelerating at that right wouldn't even be measurable with our current instruments on scales millions of times larger than the Earth, or solar system. But the distance between galaxies, in the voids, that light starts to pick up some speed. But give it what we used to think of a 7 or 8 billion light years of distance, which might just be 2 or 3 light years in reality. It gets going really fast near the end. It'll cover what we think of as a billion light years in more like a couple seconds. Because the speed increase is exponential, just like the assumed universal expansion rate is. This is also why James Webb keeps seeing things so far away they would have existed before the big bang. They are far away, they are just sooner but still far away.
How can something so obvious, as relativity of time relative to mass, is not taken into account when looking at the Standard Model looking at Dark Energy?
Because a scalar field is more likely than a tensor field. Timescapes is just replacing a scalar field with a tensor field. Now you have to assume a tensor map in your equation that is not needed with a scalar field. Mathematically you are introducing more assumptions with a tensor field than a scalar field.
@@kazedcat Yeah, but I okhams razor is good and all that, I never understood, why physics used to dismiss something as untrue just because its mathematically less convenient. Same applies to ECT.. sure you use the simpler math if it doesnt matter, but ECT has very different explanations going on when it goes do black holes and big bang... so why is it generally ignored as possiblity, just because the math is hard? (ECT also introduces a tensor field for the "torsion" of space time)
This is amazing. It's incredible how much the right naming can affect perceptions. If they'd called it "flubbulon" or "pixie dust", we'd have a very different idea (and appreciation) for "dark energy".
There is honestly nothing to fear. Given that current theories are just that, since we have a hard time factoring in dark matter due to us knowing incredibly little about it. Even an ever expanding universe will be exciting and dynamic.

greg, we told you so many times already, you can't just make a drawing with crayons, pass it off as a science theory and expect the professors to take you seriously!
People who say they hate dark energy, that's pretty much everyone because we don't fully understand it. If anything this new paper will give us a more exact way of measuring the universe's expansion.
Obviously, intuitively, "dark e" and "dark matter" are NOT ACUTUAL, but mere placeholders for a gap of understanding in the standard model (gee whiz, um within "gravity" probably). In general, out-of-nowhere fantastic disproportionately shows you that you're likely on the wrong. track..
Dark matter is effectively proven by the observation of what are called baryon oscillations. But dark energy is a placeholder for whatever gives the measurements of acceleration.
@@michaelbarnard8529 It's not proven, dark matter is one of a dozen or so theories. Dark matter gets all the play because there's a half-dozen Ph.D.'s in charge have hung their hat on that THEORY. Any cosmologist that doesn't hang his hat on that THEORY is labeled a crackpot, loses his funding, and winds up working at Starbucks.
Dark matter isn't a THEORY. No one hangs their hat on that THEORY... It is just a placeholder name for the seemingly unaccountable source of invisible mass. Why do so many think they are "gothchaing" the scientific community by calling out some BS that is apparently being claimed?
@@Skank_and_Gutterboy there's active research in other explanations, notably all kinds of MOND. Also, many people use "dark matter" as a catch-all name for "whatever it is that causes these excess-matter-like discrepancies in our observations", in which case denying dark matter is much, much tougher, since the discrepancies are so, so heavily substantiated. I think sometimes the mixup of these two usages helps create an undue impression of rigid thinking.
7:15 I think, the thing for me, that I noticed personally, was the when you deal with GINORMOUS MASSES light speed becomes slow, seeing as though it travels on a reality (REAL MASS) grid, space can be CURVED FAST and the result is way too much stuff done for light to keep up with. ❤
Both dark energy and matter smacks of The Eather, miasma and The Humors or even the crystal spheres holding up the heavens... total bulls$it and was created to explain something we still dont understand.
Disagree.The Aether was a compete fabrication based on no observational data whatsoever. DE and DM are "made up', but seem to be based on actual observational data. Very different in my mind.
The term "dark matter", was always used as -we don't know. Having never been empirically proven, and relying on pure conjecture. Inference is not proof in science and I for one never accepted it's existence. Too many fellow scientists casually spoke of "dark matter" as though it was a proven fact for far too long. We must maintain a very high bar of proof in science or face mockery for our ineptitude.
@@G0nxsf It's hard to imagine a scientist not understanding the name. The name was translated from German where it means "Mysterious Matter," and that describes our current understanding of it perfectly.
So Big crunch is real. We will go back to being part of singularity... There's no heat death. Gravitational force will eventually overcome the expansion of the universe
I don't think it's an alternative... it should be the default. Right from the moment that some people claimed inflation was needed "because there wasn't enough time". That just implies very heavy time dilation. If matter tells space how to curve, then putting in much more emptiness means relatively less matter to curve space... and let's be honest, dark energy is called dark energy because people don't know what causes said effect, so it could be anything.
When the universe expands the mass density drops - when mass density drops the gravimetric potential drops - when the gravimetric potential drops time speeds up - When observing distant objects you see them as they where in the past when time was moving slower, adding to the observed redshift - thus the expansion of the universe is not accelerated
Before we knew about gases. The air around us was a "void" or treated like "nothing". We took breaths without knowing what it was. Regardless what we call the voids of space. Like the air around us, space is something. We just don't know. Like Tesla said, “If you want to find the secrets of the universe, think in terms of energy, frequency, and vibration”
I mean it’s really simple- dark energy is a dumb assumption. It’s easier to me to assume we’re operating form A incomplete local picture. Those ‘voids’ are just mass intersections of all celestial bodies in the universe. - if you realize all matter wants to come together / all ‘space’ pushes matter away… it’s a bit easier to picture. Especially if you operate on the idea that it was 2 infinite dimensions that collided. I think the forth dimension in a sense will be layers of our third dimensions creating infinite realities via ‘black holes’ But either way we’ll see!
Note: intersection of gravity wells (if you drew a line from all atoms to other atoms where would the largest intersections be based on gravity/size etc.
@@Chris-ut8we I do operate on that idea. I think it was m-theory or something akin to that. Two membranes/dimesions colliding. Almost like sex in a way where one ejaculated matter/energy into the other. Am I just a loon for thinking this?
@@Chris-ut8weDark Energy is dumb? You obviously don't understand the video, and don't even understand thst we have a 4th dimension. It is called time... and thinking there is infijite realities via black holes, is ... just as "dumb" as dar, enrrgy. A completely and utterly unproven phenomena. Sorry, dumber, as dark energy is at least something added mathematically to metch observations. Your multiverse doesn't even have observations
In my largely unecudated mind in the field I had thought, is time dilation over large distances taken into account for determening the acceleration? Surely, that must be an obvious thing. I guess not? What? How?
Yeah it feels like people forget that being wrong is an important step of the scientific process. We start out by being very wrong (Plato's Epicycles) , and then we prove that we're wrong about something and come up with a better explanation (Newtonian Physics), and then we prove that that explanation was wrong as well and keep working on the next one (General Relativity, etc...). Hell, the current accelerating-expansion-via-dark-energy model only dates back to the late 1990's, and people have been hard at work trying to prove it wrong since then.
This has nothing to do with dark matter though. And how is dark matter a cop out, if it's just the observation that regions of the Universe behave *as if* there was invisible matter in them? An exotic new type of matter is a possible, and currently favored *preliminary* hypothesis, not dogma or even a theory. Alternative models based on adjusting gravity simply can't explain all the observations, but we also can't detect the hypothetical new type of matter. Saying "we don't know exactly what's going on, but it might be X, we have to investigate further" isn't a cop-out, itr's the heart of how science works.
If this is true it’s huge! I’m not a scientist, but I’ve always thought there might be a different explanation. None of the explanations are very “satisfying”.
We also don't know if light energy DECAYS over vast time or distance. Light is actually information, as well as particles. Over vast distances, we still treat light as a LOCAL event.
I read an article on this and was hoping you'd do a video on it. Fascinating work, and I can't wait to see o3 take on some of that tricky math. What a time to be alive!
This is very interesting but also very limited to an astronomer's point of view. Dark energy has further justification beyond compliance to astronomical data (although these justifications are much more flexible when it comes to the amount of dark energy necessary in the universe). One such example would be the zero-point energy of quantum fields and the inescapable fact that all vacuum (in a quantum world) must have positive energy (assuming it's asymptotically flat) and negative pressure. And this is completely unrelated to type 1 supernovae.
A historic comparison: When Milanković calculated precisely with just Newtonian mechanics he could explain the ice ages! Maybe a better calculation with GRT, like the time scapes theory, could explain some open problems?
I am definitly not a physicist, but I always suspected that "dark energy" is just a place-holder for a concept or mechanic we yet not understand. It is remarkable that the idea of time dilation hasn't been considered for so long, as a core mechanic explaining ever greater red shifts, as we look further back in time.
Another theory I heard about, that seems to not only explain the increased expansion, but also dark matter, and the speed of light, is our spacetime being 4D hyperbolic on a large scale...
Could be... over the last several decades there have been many add-ons to the favored cosmological model such that they feel like "fixes" to make that model keep fitting observations. What about inflation? There may be some real shifts in cosmology coming down the road.
@@takashitamagawa5881 it already has seeing as how they are forcing math into what they dont see.

David and Sam O. right around Christmas?A gift-filled day. Thanks for trying to inform the public (that for now seems to distrust all sorts of experts out of hand).
I actually glad we may move away from Dark Energy. I don't know how to put it, but I never liked that idea when we just say "You know what, most of the universe consists of that thing we don't even know what it is and how it should be called. But we will continue, with holier-than-thou face force feed you this idea, that there is some unknowable thing which fills up the whole universe and dictates everything about it's evolution". It is like trying to convince everyone for decades, that Luminiferous aether does actually exist, while being insufferable about it on the whole another level. On the topic of timescapes specifically, it may be harder on the math part, but I am not gonna lie, it feels like an elegant solution. Very big brain movements. But anyway, nice video Cool Worlds. And Merry Christmas!
1:12 Yes, more distant, (older) things are moving away from us faster than closer, (younger), things... This graph is supposed to be read from right to left. From the past to the present. It seems to show things slowing down, not speeding up as you get closer to the present age.
I'm reminded of a study from several years ago, that removed dark matter equations from a simulation of a barred spiral galaxy model and added more black holes (like billions of black holes) to the galaxy simulation and it maintained its barred-spiral structure, which partially demonstrated that Dark Matter might not necessarily exist. Granted, the study shoehorned the black holes and their origin and distribution were not considered, and there's no observational data to corroborate the study. (It was just a simulation study). However, Dark Matter and Dark Energy are also shoehorned into the equations, with no explanation as to origin or distribution.
i never thought dark energy / dark matter exists, i always thought it's just a mis-calculation. i refer to the kind of dark matter that is supposedly holding universe together, i always known it's mis-calculation. but ofcourse i'm sure there are energies that human tech is not able to detect yet, so technically you could call it "dark energy", but it's not what most people think of when they hear dark energy/matter.
Dark matter was proposed in response to observation of galaxy rotation on the edges being quicker than expected. Electric universe theory describes this as an effect of the plasma density and charge density and is scalable to any size of observation. Electromagnetic force is 40 orders of magnitude stronger than gravity yet they want us to discount its effects completely.
How is stuff like gravitational lensing in the Bullet Cluster a "miscalculation"? It's a direct observation of seemingly empty space bending light as if there was a lot of matter there. Please learn anything about the topic before you solve the greatest scientific mysteries of our times with your brilliant innate common sense and intuition.
This is incredibly exciting news. Honestly I have never realistically hoped I might get a conclusive answer to the mysteries of what is dark matter and what is dark energy. The simple fact of the matter is proving that one of them does not exist is equivalent to proving what it is, and that this might happen in my own lifetime is very exciting.
This is PRECISELY WHY Science will ALWAYS supercede Religion! Science continually corrects itself, as time goes by! And this self-correcting mechanism, allows Science to grow, adapt and get better at making predictions, as it evolves... Throwing out well established ideas, if they don't fit new data! One really cannot say the same for Religion which tends to be fixed, rigid and static!!
This choose-your-team rhetoric is always damaging to both, however. The main issue the video presents is precisely scientists, for decades, not being able to overlook what was essentially a dogmatically-imposed idea, despite all the stacking evidence against it. On the other hand, religions are not "fixed, rigid and static", otherwise we wouldn't have such a diversity of them, both geographically and historically.
Hate to break it to you, but there is a bigger illusion at play. I'm just wondering how long it will take everyone to see it! Watching from a distance 🤨
It's a terrible indictment of the scientific establishment, and the prevalence of group think within it, that this wasn't realised earlier. It's absolutely trivial to realise this was something that should be looked into and worked on as a priority.
“Is there any chance our theory might be imperfect?” “No, no, there’s probably just titanically huge amounts of completely imperceptible matter and energy that, if it existed, would mean our theory was right all along.” “Oh, ok, that makes sense.” I love dark matter. It inspired me to come up with my dark girlfriend.
I've teased Neil a bit too about the biology thing, but I think he was just trying to navigate through a touchy sociopolitical subject without offending a particular group, it didn't go so well. I agree, how about we try not to gaslight him when he wasn't even mentioned in this video?
Thank you, I've had similar ideas for years now and have always found it frustrating how many physicists would rather take undetectable dark energy as answer, rather than exploring the possibility of good old time dilation. I think we need more explanation and simulation on how time dilation changes the perception from different points of view. When simulating in my head, I can imagine all kinds of crazy effects of morphing spacetime, including what the timescape theory suggests.
Wow, Dr. Kipping!!! We are, indeed, living in interesting times. As you say, the beauty of science is it is self-correcting. Moreover, as we look back over the millennia, the time required to self-correct has steadily reduced. It used to take centuries, as in the time of Aristotle, so that the man in the street did not live long enough to become uncomfortable with the new paradigm. Now, the time required has reduced to decades so that that man in the street has continuously been knocked off balance, leading to a distrust of science. So it is that voices like yours are increasingly critical for a broad understanding. It is your infectious enthusiasm and your words, " stay thoughtful and stay curious", that makes the journey so exciting. Never change, Dr. Kipping! We all need you!
so, if timescapes is correct, there's no increasing expansion, there's a fixed expansion, there's a slowing expansion or there's no expansion at all? I hope at some point they tell us what the universe is doing net of the optical illusion.
🙂 Aside: Einstein disregarded one of the two observers (two systems through motion). At the very beginning of his SRT genesis. Everything from here on is unscientific nonsense. Relativity is symmetric.
We are still in the process of understanding the universe..As we live very short span of time we believe those theories and calculations are correct in our generation which might be wrong for next generation tech observations
It’s comforting as a layman that, although I’m completely puzzled by the universe, the eggheads are essentially clueless also. Thanks for mentioning Ryan Ridden. Just subscribed to his channel.
Holy hell. I'm gonna have to keep on top of this. As a sci fi writer, I was thinking on this and had kernels of ideas that were leading to timescapes. Obviously without the actual math and work that went into it, but buddy might owe me 2 beers now.
Speaking of things which are non-trivial, the complete absence of evidence, and even the possibility of measuring, either dark-matter or dark-energy places them into the field of fairy tales.
I always thought of dark energy as an abstract concept of “something doesn’t make sense and we need more information to make a conclusion.” Could be something physical, a force, or nothing.
Why would light 'stretch out' due to expanding space? Photons don't vibrate in space so it shouldn't affect the wavelength. Expanding time does affect the measurement of frequency which is why it will appear blue shifted, not because it gains energy in some kind of gravity well.
It never sat well with me. They observed an anomaly that the universe seems to be expanding, so they immediately assume it's "dark energy" without being able to say anything more about it.
another awesome video show casing a new voice I haven't seen and glad to follow. Dr. Ryan's channel looks fun and I'm always looking for science communicators!
Big if true because it'd help with removing not only a made up term but if it turns out that it can predict that the expansion of universe won't continue indefinitely it's a very satisfying result aesthetically too. I hate the idea of heat death. Merry Christmas btw!

In other words, they have been designed (I let you imagine "something" that takes mathematics as in input and outputs carved stone...), the precision matches modern CNC machines. The catch? We found them under the stepped pyramid, the origin of their discovery is documented and not controversial.
(we have CT scans, 3D models, mathematicians looked at them, electron microscopy, and metrology done on them. STL files are publicly available. All of the above is 100% factual)
Anyone looking into this will conclude that we are not the first advanced civilization on this planet.
Whoever brings that up will get relentlessly and ruthlessly attacked, defamed, and shamed.
That's just one example.
The unfinished obelisk of Aswan is hand-waved by scientists. It's 1,200 metric tonnes, we could lift it today, it would take 36 modern cranes, then the only thing you could do is put it back because with 36 cranes around that thing, you're not going anywhere. Egyptians made an even bigger, estimated at 1,400 metric tonnes. Where is it? We don't know, there's only the hole left. If it was just 2 feet away, it would already be a mystery, it's literally nowhere to be found. Question any of this, you'll be attacked.
Oh, by the way, on the wall of the hole where that 1,400 metric tonnes obelisk are drawings, still visible to this day, that are known to predate even Old Kingdom Egyptians... Question that, you'll be attacked.
Around the Spinx are wall, it's actually in an enclosure. The ground was excavated, the middle part wasn't and that's how the made the sphinx, 4,500 years ago, according to science. The issue? There is signs of tens of thousands of years worth of erosion on the enclosure. Question that... You know the drill...
I could go on and on, it's gotten to a point that I believe that the most used tool in all of science isn't a microscope, a scalpel or a lab coat but shame. I've seen more shame being used than microscopes.
And it's nothing knew. Look into the guy who invented soap. Those who doubted evolution or crust displacement theory, they were all relentlessly and viciously attacked. You have romanticized scientists, which is okay, but it shows that you don't have a Twitter account... Those guys aren't wise old men with tame rhetoric, most of them behave like 14 years old on the internet or Mark Hamil...
We don’t know shit
It’s interesting how the preference for elegance and simplicity over messiness and complexity has at times led us to hold onto theories for longer than we should have. But this is how paradigm shifts begin, according to Kuhn. An alternative theory arises that better explains a certain piece of data. Then it begins to explain other observations that don’t fit into the existing model. At a certain point, the existing theory gets so weighted down with messy complexity (epicycles) that the new theory begins to seem more elegant.
The problem is that beauty won't go away, it just morphs into different parameters over time, it is too subjective and is preventing good theories to emerge because they don't meet the right beauty flavor of the time.
As a math nerd, I get the admiration for beauty, but real scientists should not let it ultimately determine their findings, lol.
That’s sounds like what’s happened to the Electric Universe model.
Except, it is older than the Big Bang… was and still is suppressed in favor of the current cosmological crisis.
We can’t have a theory that includes electrogravitics when we’re also trying to keep the advanced technology to a minimum. 😉
So to recap, Timescapes is saying that due to absence of gravitational bias through voids it's causing a red shift that we mistook for an accelerating Universe? I mean... I really hope this is true for the future civilizations after us.
This doesn't necessarily mean the universe isn't expanding, but it does mean that the known models would be completely wrong about the rate of expansion if it is actually expanding, in theory though this does open up the possibility of a renewal of other universal ends like the big crunch because we wouldn't be capable of measuring alot of things properly at that point, even the age of the universe would be questionable if this is proven true.
It's almost right too, but it's not. I went through all the calculations a few days ago and the answer is simpler and much more intuitive and elegant then even that. Because it doesn't explain why the universe appears to be expanding at an increasing rate. It only assumes the cause of red shifting, because we haven't been able to prove why light red shifts at all. Only that it does and more so in objects further away. But the accelerating universal expansion thing requires space to be expanding, we can't observe that locally in any way at all. It's not the universe that's expanding but light is accelerating. It does so more absent the interference of gravity. So once the light makes it into intergalactic space it will continue to accelerate forever as the wavelength lengthens. The photon has no mass, it's simply a transfer of energy from one form to another, wavelength to velocity. But at that speed the light doesn't experience time itself. It is the distances that cause the wavelength to stretch out and increase the speed like a spring uncoiling. That is the only thing that explains why the universe looks like the acceleration of the expansion is real. It's the light accelerating, not the universe. It solves every mystery, eliminates the need for dark matter and dark energy entirely and makes all our observations make total intuitive sense. It even explains why galaxies rotations seem too fast to hold themselves together. I spent hours doing the math with an Ai double checking everything. It couldn't find any problems with it either. I had to train the model on the concept first, I wanted to know if I was missing anything. So we plugged the math into everything it might break and it all worked better. It only breaks the need for dark matter and dark energy. Which obviously don't exist and never did. Or we'd have seen them. It even won't affect our technology in any way. Light accelerating at that right wouldn't even be measurable with our current instruments on scales millions of times larger than the Earth, or solar system. But the distance between galaxies, in the voids, that light starts to pick up some speed. But give it what we used to think of a 7 or 8 billion light years of distance, which might just be 2 or 3 light years in reality. It gets going really fast near the end. It'll cover what we think of as a billion light years in more like a couple seconds. Because the speed increase is exponential, just like the assumed universal expansion rate is. This is also why James Webb keeps seeing things so far away they would have existed before the big bang. They are far away, they are just sooner but still far away.
So. Turtles all the way down, then? @@MikeJones-wp2mw
True. Imagine this voids all travel at their own unique speeds… calculating the age of the universe would be impossible it would seem.
@@MikeJones-wp2mwHow can light accelerate it already travels at the speed limit?
How can something so obvious, as relativity of time relative to mass, is not taken into account when looking at the Standard Model looking at Dark Energy?
Math too hard 🤷♂️
Publish or perish with a dollop of click-bait.
@@iAnasaziphysicist increasingly can’t do the math .. so, yeah
Because a scalar field is more likely than a tensor field. Timescapes is just replacing a scalar field with a tensor field. Now you have to assume a tensor map in your equation that is not needed with a scalar field. Mathematically you are introducing more assumptions with a tensor field than a scalar field.
@@kazedcat Yeah, but I okhams razor is good and all that, I never understood, why physics used to dismiss something as untrue just because its mathematically less convenient. Same applies to ECT.. sure you use the simpler math if it doesnt matter, but ECT has very different explanations going on when it goes do black holes and big bang... so why is it generally ignored as possiblity, just because the math is hard? (ECT also introduces a tensor field for the "torsion" of space time)
This is amazing.
It's incredible how much the right naming can affect perceptions.
If they'd called it "flubbulon" or "pixie dust", we'd have a very different idea (and appreciation) for "dark energy".
I'd like it more if they called it flubbulon. I mean if they can name a particle that holds things together the gluon, why not
This development is extremely important to me. It significantly lowers my existential angst.
I agree
Good to know there are others out there that understand what it is like. :)
Why? It existing or not doesn't change the core concept of reality or the size of the universe
I also wonder why! Were you scared of dark energy? Or that the universe might expand into nothingness?
There is honestly nothing to fear. Given that current theories are just that, since we have a hard time factoring in dark matter due to us knowing incredibly little about it. Even an ever expanding universe will be exciting and dynamic.

I always thought "dark matter" sounds more like a "space holder" for "we just don't know".....
Sorta? It is a place holder but its based on observable data. It may or may not exist but we use it to try and make our theoretical maths work.
I said this 8 years ago, got told I should go to mental hospital. I even sent in my theory to a university, they never replied. Probably thought I was on drugs or something.
greg, we told you so many times already, you can't just make a drawing with crayons, pass it off as a science theory and expect the professors to take you seriously!
Good, I'm happy there's progress on this. I've always hated dark energy and dark matter to a lesser degree
People who say they hate dark energy, that's pretty much everyone because we don't fully understand it. If anything this new paper will give us a more exact way of measuring the universe's expansion.
Obviously, intuitively, "dark e" and "dark matter" are NOT ACUTUAL, but mere placeholders for a gap of understanding in the standard model (gee whiz, um within "gravity" probably). In general, out-of-nowhere fantastic disproportionately shows you that you're likely on the wrong. track..
Dark matter is effectively proven by the observation of what are called baryon oscillations. But dark energy is a placeholder for whatever gives the measurements of acceleration.
@@michaelbarnard8529
It's not proven, dark matter is one of a dozen or so theories. Dark matter gets all the play because there's a half-dozen Ph.D.'s in charge have hung their hat on that THEORY. Any cosmologist that doesn't hang his hat on that THEORY is labeled a crackpot, loses his funding, and winds up working at Starbucks.
Dark matter isn't a THEORY. No one hangs their hat on that THEORY... It is just a placeholder name for the seemingly unaccountable source of invisible mass. Why do so many think they are "gothchaing" the scientific community by calling out some BS that is apparently being claimed?
@@Skank_and_Gutterboy there's active research in other explanations, notably all kinds of MOND.
Also, many people use "dark matter" as a catch-all name for "whatever it is that causes these excess-matter-like discrepancies in our observations", in which case denying dark matter is much, much tougher, since the discrepancies are so, so heavily substantiated. I think sometimes the mixup of these two usages helps create an undue impression of rigid thinking.
No scientists have been looking for the fuse of those things
Merry Christmas, Dr. David Kipping and all of the Cool Worlds Lab and affiliates! 🎄
That's a narrow list for Christmas wishes, I'm just sayin'.
7:15 I think, the thing for me, that I noticed personally, was the when you deal with GINORMOUS MASSES light speed becomes slow, seeing as though it travels on a reality (REAL MASS) grid, space can be CURVED FAST and the result is way too much stuff done for light to keep up with. ❤
Both dark energy and matter smacks of The Eather, miasma and The Humors or even the crystal spheres holding up the heavens... total bulls$it and was created to explain something we still dont understand.
Disagree.The Aether was a compete fabrication based on no observational data whatsoever. DE and DM are "made up', but seem to be based on actual observational data. Very different in my mind.
@@alanjackson1015kind of like field theory these days
But how do you know it's BS if you don't understand it:?
Exactly
The term "dark matter", was always used as -we don't know. Having never been empirically proven, and relying on pure conjecture. Inference is not proof in science and I for one never accepted it's existence. Too many fellow scientists casually spoke of "dark matter" as though it was a proven fact for far too long. We must maintain a very high bar of proof in science or face mockery for our ineptitude.
Dark Energy is not even remotely relevant to Dark Matter though? What are you on about?
@@G0nxsf
It's hard to imagine a scientist not understanding the name. The name was translated from German where it means "Mysterious Matter," and that describes our current understanding of it perfectly.
So Big crunch is real. We will go back to being part of singularity... There's no heat death. Gravitational force will eventually overcome the expansion of the universe
Would be a paradigm shift
@CoolWorldsLab 💯
@@CoolWorldsLab
Paradigm shifts will happen when their is a lull for fifty years
@@CoolWorldsLab the world could use a few paradigm shifts...
I'm looking forward to it.😊
I don't think it's an alternative... it should be the default. Right from the moment that some people claimed inflation was needed "because there wasn't enough time". That just implies very heavy time dilation. If matter tells space how to curve, then putting in much more emptiness means relatively less matter to curve space... and let's be honest, dark energy is called dark energy because people don't know what causes said effect, so it could be anything.
Exotic Matter, it's some cosmic scale and kind of EM that is causing it, like we've seen bizarre things with that stuff like Superionic Ice.
Woho Merry Christmas!
I've never bought the dark energy theory, even when it really seemed to work.
Merry Christmas! 🎁🎄
When the universe expands the mass density drops - when mass density drops the gravimetric potential drops - when the gravimetric potential drops time speeds up - When observing distant objects you see them as they where in the past when time was moving slower, adding to the observed redshift - thus the expansion of the universe is not accelerated
Time has no properties, it is a concept, saying time speeds up is no different than stating the number 5 slows down, time is only a measure.
that is one big "thus" : p
Errr... you are making a hellalota assumtions for a thus.
Before we knew about gases. The air around us was a "void" or treated like "nothing". We took breaths without knowing what it was. Regardless what we call the voids of space. Like the air around us, space is something. We just don't know.
Like Tesla said, “If you want to find the secrets of the universe, think in terms of energy, frequency, and vibration”
I mean it’s really simple- dark energy is a dumb assumption.
It’s easier to me to assume we’re operating form
A incomplete local picture.
Those ‘voids’ are just mass intersections of all celestial bodies in the universe. - if you realize all matter wants to come together / all ‘space’ pushes matter away… it’s a bit easier to picture.
Especially if you operate on the idea that it was 2 infinite dimensions that collided.
I think the forth dimension in a sense will be layers of our third dimensions creating infinite realities via ‘black holes’
But either way we’ll see!
Note: intersection of gravity wells (if you drew a line from all atoms to other atoms where would the largest intersections be based on gravity/size etc.
@@Chris-ut8we I do operate on that idea. I think it was m-theory or something akin to that. Two membranes/dimesions colliding. Almost like sex in a way where one ejaculated matter/energy into the other. Am I just a loon for thinking this?
@@Chris-ut8weDark Energy is dumb? You obviously don't understand the video, and don't even understand thst we have a 4th dimension. It is called time... and thinking there is infijite realities via black holes, is ... just as "dumb" as dar, enrrgy. A completely and utterly unproven phenomena. Sorry, dumber, as dark energy is at least something added mathematically to metch observations. Your multiverse doesn't even have observations
In my largely unecudated mind in the field I had thought, is time dilation over large distances taken into account for determening the acceleration? Surely, that must be an obvious thing. I guess not? What? How?
I love how science and the scientific method is self correcting.
Also, I never liked the idea of dark matter and energy. It felt like a cop-out.
Yeah it feels like people forget that being wrong is an important step of the scientific process. We start out by being very wrong (Plato's Epicycles) , and then we prove that we're wrong about something and come up with a better explanation (Newtonian Physics), and then we prove that that explanation was wrong as well and keep working on the next one (General Relativity, etc...). Hell, the current accelerating-expansion-via-dark-energy model only dates back to the late 1990's, and people have been hard at work trying to prove it wrong since then.
This has nothing to do with dark matter though. And how is dark matter a cop out, if it's just the observation that regions of the Universe behave *as if* there was invisible matter in them? An exotic new type of matter is a possible, and currently favored *preliminary* hypothesis, not dogma or even a theory. Alternative models based on adjusting gravity simply can't explain all the observations, but we also can't detect the hypothetical new type of matter. Saying "we don't know exactly what's going on, but it might be X, we have to investigate further" isn't a cop-out, itr's the heart of how science works.
The idea of the universe not expanding is sensible, but radically changes how I was taught to think of it
It’s still expanding, just not an increasingly faster rate
It’s not that it isn’t expanding, just that the expansion might not be accelerating.
If this is true it’s huge! I’m not a scientist, but I’ve always thought there might be a different explanation. None of the explanations are very “satisfying”.
We also don't know if light energy DECAYS over vast time or distance. Light is actually information, as well as particles. Over vast distances, we still treat light as a LOCAL event.
Merry christmas guys

Merry Christmas and Happy Holidays, everyone
Your passion and excitement for this field is contagious. I love your videos and the work you do
This is very interesting but also very limited to an astronomer's point of view. Dark energy has further justification beyond compliance to astronomical data (although these justifications are much more flexible when it comes to the amount of dark energy necessary in the universe). One such example would be the zero-point energy of quantum fields and the inescapable fact that all vacuum (in a quantum world) must have positive energy (assuming it's asymptotically flat) and negative pressure. And this is completely unrelated to type 1 supernovae.
Thanks for this
Been saying this for years.
Pay no attention the dark matter / energy behind the curtain
You're a genius!
I’ve always felt that dark energy was a placeholder for maintaining relativity while at the same time throwing our hands in the air.
Same here.
What a fascinating Christmas present, many thanks Cool Worlds! Seasons greetings to you and the team!
A historic comparison: When Milanković calculated precisely with just Newtonian mechanics he could explain the ice ages!
Maybe a better calculation with GRT, like the time scapes theory, could explain some open problems?
I am definitly not a physicist, but I always suspected that "dark energy" is just a place-holder for a concept or mechanic we yet not understand. It is remarkable that the idea of time dilation hasn't been considered for so long, as a core mechanic explaining ever greater red shifts, as we look further back in time.

"Dark energy -- It's this thing that's all over the universe that we can't see, or know what it's made of... " what could go wrong? 😂
Another theory I heard about, that seems to not only explain the increased expansion, but also dark matter, and the speed of light, is our spacetime being 4D hyperbolic on a large scale...
Dark matter next to fall.
Could be... over the last several decades there have been many add-ons to the favored cosmological model such that they feel like "fixes" to make that model keep fitting observations. What about inflation? There may be some real shifts in cosmology coming down the road.

I actually glad we may move away from Dark Energy. I don't know how to put it, but I never liked that idea when we just say "You know what, most of the universe consists of that thing we don't even know what it is and how it should be called. But we will continue, with holier-than-thou face force feed you this idea, that there is some unknowable thing which fills up the whole universe and dictates everything about it's evolution". It is like trying to convince everyone for decades, that Luminiferous aether does actually exist, while being insufferable about it on the whole another level.
On the topic of timescapes specifically, it may be harder on the math part, but I am not gonna lie, it feels like an elegant solution. Very big brain movements.

I'm reminded of a study from several years ago, that removed dark matter equations from a simulation of a barred spiral galaxy model and added more black holes (like billions of black holes) to the galaxy simulation and it maintained its barred-spiral structure, which partially demonstrated that Dark Matter might not necessarily exist.
Granted, the study shoehorned the black holes and their origin and distribution were not considered, and there's no observational data to corroborate the study. (It was just a simulation study).
However, Dark Matter and Dark Energy are also shoehorned into the equations, with no explanation as to origin or distribution.
i never thought dark energy / dark matter exists, i always thought it's just a mis-calculation. i refer to the kind of dark matter that is supposedly holding universe together, i always known it's mis-calculation.
but ofcourse i'm sure there are energies that human tech is not able to detect yet, so technically you could call it "dark energy", but it's not what most people think of when they hear dark energy/matter.
Dark matter was proposed in response to observation of galaxy rotation on the edges being quicker than expected. Electric universe theory describes this as an effect of the plasma density and charge density and is scalable to any size of observation. Electromagnetic force is 40 orders of magnitude stronger than gravity yet they want us to discount its effects completely.
How is stuff like gravitational lensing in the Bullet Cluster a "miscalculation"? It's a direct observation of seemingly empty space bending light as if there was a lot of matter there. Please learn anything about the topic before you solve the greatest scientific mysteries of our times with your brilliant innate common sense and intuition.
Hope you had a good Christmas, these videos are always a good time!
This is incredibly exciting news. Honestly I have never realistically hoped I might get a conclusive answer to the mysteries of what is dark matter and what is dark energy. The simple fact of the matter is proving that one of them does not exist is equivalent to proving what it is, and that this might happen in my own lifetime is very exciting.
This is PRECISELY WHY Science will ALWAYS supercede Religion! Science continually corrects itself, as time goes by! And this self-correcting mechanism, allows Science to grow, adapt and get better at making predictions, as it evolves... Throwing out well established ideas, if they don't fit new data!
One really cannot say the same for Religion which tends to be fixed, rigid and static!!
That's like stating that live action movies will always look more realistic than animated movies. Yeah. They do. But what's the point?
This choose-your-team rhetoric is always damaging to both, however. The main issue the video presents is precisely scientists, for decades, not being able to overlook what was essentially a dogmatically-imposed idea, despite all the stacking evidence against it. On the other hand, religions are not "fixed, rigid and static", otherwise we wouldn't have such a diversity of them, both geographically and historically.
It's not expanding, and we should all see illusions. Dark matter/energy was an hallucination which became dogma.

Thank you, I've had similar ideas for years now and have always found it frustrating how many physicists would rather take undetectable dark energy as answer, rather than exploring the possibility of good old time dilation.
I think we need more explanation and simulation on how time dilation changes the perception from different points of view.
When simulating in my head, I can imagine all kinds of crazy effects of morphing spacetime, including what the timescape theory suggests.
Merry Christmas to you Professor and the whole Cool Worlds lab! You’re a huge inspiration and hope this next year is a great one for you!
Wow, Dr. Kipping!!! We are, indeed, living in interesting times. As you say, the beauty of science is it is self-correcting. Moreover, as we look back over the millennia, the time required to self-correct has steadily reduced. It used to take centuries, as in the time of Aristotle, so that the man in the street did not live long enough to become uncomfortable with the new paradigm. Now, the time required has reduced to decades so that that man in the street has continuously been knocked off balance, leading to a distrust of science. So it is that voices like yours are increasingly critical for a broad understanding. It is your infectious enthusiasm and your words, " stay thoughtful and stay curious", that makes the journey so exciting. Never change, Dr. Kipping! We all need you!
This shows exactly why "settled science" is the opposite of actual science. Science is the unending process of questioning everything.
so, if timescapes is correct, there's no increasing expansion, there's a fixed expansion, there's a slowing expansion or there's no expansion at all? I hope at some point they tell us what the universe is doing net of the optical illusion.
🙂
Aside: Einstein disregarded one of the two observers (two systems through motion). At the very beginning of his SRT genesis. Everything from here on is unscientific nonsense.
Relativity is symmetric.
We are still in the process of understanding the universe..As we live very short span of time we believe those theories and calculations are correct in our generation which might be wrong for next generation tech observations
It’s comforting as a layman that, although I’m completely puzzled by the universe, the eggheads are essentially clueless also.

Holy hell. I'm gonna have to keep on top of this. As a sci fi writer, I was thinking on this and had kernels of ideas that were leading to timescapes. Obviously without the actual math and work that went into it, but buddy might owe me 2 beers now.
Speaking of things which are non-trivial, the complete absence of evidence, and even the possibility of measuring, either dark-matter or dark-energy places them into the field of fairy tales.
I always thought of dark energy as an abstract concept of “something doesn’t make sense and we need more information to make a conclusion.” Could be something physical, a force, or nothing.
Why would light 'stretch out' due to expanding space? Photons don't vibrate in space so it shouldn't affect the wavelength. Expanding time does affect the measurement of frequency which is why it will appear blue shifted, not because it gains energy in some kind of gravity well.
Excellent video for a slow Christmas afternoon! Thanks for making the holidays brighter!
It never sat well with me. They observed an anomaly that the universe seems to be expanding, so they immediately assume it's "dark energy" without being able to say anything more about it.
another awesome video show casing a new voice I haven't seen and glad to follow. Dr. Ryan's channel looks fun and I'm always looking for science communicators!

Anime fan ♥️ 😂
I appreciate Dr. Kipping’s use of stupendous memes.
That’s a super interesting gift for xmas ❤ 😅 thank you Prof. Cool Worlds. Keep up the good work ❤❤❤
Its like adding oil to the soapy water, it accelerates artificially for a small period of time due to the surface tension being broken.
Big if true because it'd help with removing not only a made up term but if it turns out that it can predict that the expansion of universe won't continue indefinitely it's a very satisfying result aesthetically too. I hate the idea of heat death. Merry Christmas btw!
Very interesting!! Merry Christmas!!
What is baptised “Dark Energy” is most probably a byproduct or an observed effect of something much deeper, stretching the shape of space.
Any update on your JWST exomoon observations?
This is great! This is the very nature of scientific exploration.
