As an experienced civil engineer, we should take the average and round it to the nearest integer and then call it a day. Any difference would be not constructible any way.
"It's important for a scientist talking about speculative ideas to remember to not believe what they think" is something that should be taught in high school. Bless you for saying this!
I used to work on fire alarms. One time we had a problem where the alarm wasn't being heard in one room of a factory. Everything was installed correctly, the volume output of the device was where it should have been, there was nothing we could find that would explain why it wasn't working. Then they turned on the machinery. It turns out the frequency of the sound of the machine was canceling out the frequency of the notification device.
I designed over 9000 sounds (over the course of about one decade). I can confirm that resonance is indeed a tricky thing, and unexpected cancellations can occur in both the most bizarre ways, but sometimes also the "obvious yet not so obvious" manners as well. 😁 There was one particular sound I generated (of those 9000+) which essentially resonated at the exact frequency of the speaker tubes it was going to be played within. ANY other speaker system was fine... but not the typical place where the sound was going to end up being played. Lemme tell ya... THAT... was a *disaster*. 😂 I chased that issue around until I realized everyone was usin' tinier speakers (28mm?), but my test projects had 36mm and 40mm ones. 🙄 Yeesh. *ONE* sound out of 9000. Drove me nutttzzz.
Even though I wasn't much interested at first, I enjoyed this. Nice, clear and concise, exactly what physics *should* be. I'm a fan of elegant simplicity.
Awesome video as always! Another detail about where disagreement lurks between general relativity and quantum theory. Thank you for the information, Dr. Don
Adding up all wavelengths sounds like when I ordered EVERY toppings on my pizza (I could choose any with no additional charge). I thought I was smart, until I received the pizza, and realized that the total amount of toppings is always the same, and it is shared amongst my choices. So I got a little of everyhting.
When wavelengths are mentioned I think about electromagnetic radiation, which has frequency and amplitude. Would the amplitude of the "hum" decrease as the frequency increased, with the amplitude approaching zero as the frequency approaches infinity? I've been a radio comms engineer for half a century, and the two waveforms are probably different things, and I'm talking garbage. But if you don't ask, you don't get.
That is not the question. Earth prevented from computing the true question due to interference from the Golgafrinchans. Furthermore, even without said interference, Earth was destroyed minutes before the question was scheduled to be complete. Also, it is suggested that it is impossible for the question and the answer to be simultaneously known in any given universe.
I was thinking it seem analogous. It seems those low frequency stacking is a problem and other physics stops it. This is lay person conjecture, but it also seems similar to the mystery of matter or how matter and anti-matter canceled except a small percentage did not.
Again, thank you, the public needs to hear your voice and others like you. We need scientists to be honest like this too, and humble before the great mysteries of the cosmos. Always let's keep the basic questions alive
With this one, I think it's best to keep in mind a fundamental verification problem of theories of empty space. How would one verify a theory of empty space, if empty space can't be measured directly? The General Relativity approach appears to be subtractive - to take out all the "stuff". The Quantum Mechanical approach also appears to be subtractive - to cancel out all the wavelengths. I wonder if these two approaches don't produce different empty spaces? In theory, it appears that they do. General Relativistic empty space seems to be some volume, but the quantum mechanical solution makes it difficult to even verify that much!
When physicists talk about the Higgs Boson giving mass to other particles, they're actually talking about the zero-particle state (vacuum state) of the Higgs Field. If there were no residual fluctuations in fields in their vacuum state, this wouldn't work, and electrons would be massless (most of the everyday stuff around us would still have mass because most of the mass of protons and neutrons isn't from the Higgs).
'SPACE': Consider the following: a. Modern science claims that all matter is made up of quarks, electrons and interacting energy. Quarks and electrons being considered charged particles, each with their respective magnetic field with them. b. Light, 'electromagnetism', in the visual light portion of the spectrum fills outer space as well here on this Earth. That is why we can see things here on this Earth as well as far away stars, galaxies, etc. c. 'Electromagnetism' ('em') also comes in other energy frequencies besides visual light: Radio waves, Microwaves, Infrared waves, Visual light waves, Ultraviolet waves, x-rays, and gamma waves. (Also in outer space and here upon this Earth at various locations). d. Modern science claims that 'em' can interact with matter. QED (Quantum Electro Dynamics) whereby 'em' interacts with electrons in atoms and molecules and QCD (Quantum Chromo Dynamics) whereby 'em' interacts with the nucleus of atoms. e. 'Gravity' also appears to actually exist, with at least varying densities if not even varying frequencies. So, 'space' is energy itself, primarily energy fields with the primary modalities of gravity, electrical and magnetic. 'Time' most probably is the 'flow of energy', 'spacetime' being 'energy and it's flow'. And the current analysis indicates that both space and time always existed and never had a beginning (also as modern science claims that energy cannot be created nor destroyed). * The singular big bang theory is a fairy tale for various reasons.
What if such a thing as "empty space" or what we imagine as zero of anything doesn't exist , or doesn't exist in in our dimension. There is always us moving through something. Same with the concept of zero. I see how we use zero for counting but it might not really be just a value of opposing forces which also is never absolute zero but just zero average of those opposing forces... (different mathematics). I don't know...
LINCOLN!!!! I've been watching you for years now. Questions on Lincoln Logs of years ago aside, you do good work, and are probably underrated as a science communicator. Maybe that's because you concentrate on work as well as communication! Keep up the learnin' brother. #ENLEARNIFICATE!
@patricklincoln5942 he's obviously talking about the man in this video. His name is Don Lincoln, but even if I didn't know that, it would be easy to infer from the comment that the man in the video is named Lincoln.
There is only one thing on this topic that we can be fairly confident of, and that it we're missing some part of the answer. What that part is.... could be quantized spacetime, could be extra dimensions, could be a bug in the simulation code, could be a non-integer number of angels dancing on the head of each pin......
I feel that absolute "nothing" or zero doesn't actually exist. To define nothing you need something and therefore we are. Nothing of what? Nothing of something. Just the thought of nothing creates on a quantum level a change (something). Nothing doesn't exist. It's always negative and positive opposites of something.
@@Aracuss Interesting philosophically, but it doesn't solve the problem. We can take the limit where less and less exists in a space. And even if not, the quantum vacuum energy actually also exists when we don't assume a vacuum, on top of the other stuff, and is still incompatible with GR.
This got me thinking that could the size or amount of empty space affect the summing of all those waves? Right after the Big Bang, the space was relatively tiny, so the dark energy could have been very strong causing inflation. But then the Universe got huge and dark energy got weaker, until now that that there is more empty space due to expansion to make it stronger again so it can start to override gravity. This probably makes no sense, but this thought came to mind while watching this video. Keep up the good work, Don! You rock!
1. In awe of humility built into the "scientific method". 2.Notion of "belief" is a quicksand whether viewed religiously or philosophically 3. Scientific position trumps ego always as methods are always happy to be disproven. 4. Alternative, endless cheap vacuum energy maybe within reach!
15 years ago, I was talking with a couple Germans in a restaurant, who, after a few too many beers, came up with the perfect solution to the problem: If we work in base 10^120, the predictions agree to within an order of magnitude, and the problem disappears. 😂
First of all: the relativistic answer is based on an observation, GR doesn't predict any empty space energy. And second, measurements of the casimir force give us a practical indication of the energy and thereby proove that the QM theoretical approach is wrong. So you are not comparing two theories, you are comparing a (possibly wrong) conclusion of an oberservation to a definitely wrong theoretical result.
(from Henry V, spoken by King Henry) Once more unto the breach, dear friends, once more; Or close the wall up with our English dead. In peace there's nothing so becomes a man As modest stillness and humility: But when the blast of war blows in our ears, Then imitate the action of the tiger; Stiffen the sinews, summon up the blood, Disguise fair nature with hard-favour'd rage; Then lend the eye a terrible aspect; Let pry through the portage of the head Like the brass cannon; let the brow o'erwhelm it As fearfully as doth a galled rock O'erhang and jutty his confounded base, Swill'd with the wild and wasteful ocean. Now set the teeth and stretch the nostril wide, Hold hard the breath and bend up every spirit To his full height. On, on, you noblest English. Whose blood is fet from fathers of war-proof!

@@GradyPhilpotton and on and on and on, I think the phrase originated prior from the infamous dispute between Thomas Nashe and Gabriel Harvey, where Harvey writes: "The eagle does not catch flies"
Most people seem to misunderstand the meaning of "The game's afoot", including script writers for modern adaptations. "Game" here isn't in the sense of "play" or "sport". It means an animal that is being hunted. Hunted animals will often seek a hiding place and remain there, so hunters would use dogs, other people, or whatever to scare the game out of its hiding place. The game would then be in the open, running away, and it was time for the hunters to start chasing it. Hence the cry "The game's afoot!", which grew into the wider sense of "After waiting, it's time to act".
"By the way, you shouldn't believe that idea. I certainly don't. It's important for scientists talking about speculative ideas to remember to not believe what they think." Reminds me of a famous saying, something to the effect of: "One of the properties of a sophisticated mind is the ability to entertain an idea without necessarily accepting it." Don't recall who said it... Fred
Imagine showing your Physics professor maths in 1996 that suggested the "universal expansion" is accelerating only to have the discussion shutdown because, at that time, the "cosmological constant" was "known to be zero"... then, two years later... Lol
@@Vatsek Which fits my prediction perfectly as to varying rates of the passage of time as one make observations further and further back in time - consistent with the two observations of gravitational waves traveling faster than light, the further the greater the difference in arrival time. BTW - gravitational waves are not demonstrating any "redshift" - let THAT sink in 🙂
After some thought agree with the two field approach ... The worst prediction in physics is often attributed to the cosmological constant problem. The cosmological constant itself is a purely derived constant and not a fundamental one. So, which fundamental constant should we consider when addressing this problem? Another constant used in general relativity is referred to as Einstein’s constant kappa, which Einstein merely considered as a constant connected to Newton’s gravitational constant. From a quantum perspective, the energy density of empty space is equal to or proportional to Planck’s energy density. Restating Einstein’s constant in terms of energy density, it becomes the Planck frequency squared divided by the Planck energy density. If we express the cosmological constant in terms of frequency squared, we can determine the energy density of the universe. After rearranging some terms, the energy density of the universe becomes the Planck energy density multiplied by the ratio of the cosmological constant’s frequency squared to the Planck frequency squared. This frequency squared ratio is crucial for understanding the cosmological constant problem. In mechanical vibration, the frequency squared ratio often serves as an amplification/damping ratio or coupling constant. Therefore, we can assume that the cosmological constant’s energy density is coupled to the Planck energy density, accounting for the 120 orders of magnitude difference.
This will challenge a lot of physics on both sides and connect them through photon singularity. Summary Here are the key components of all my physics posts. Photons are eternal and outside of time and distance. The singularity of photons began the Big Bang. Photons created mass through pair conversion of electron positron pairs in the Big Bang. These electrons and positrons made the elementary particles which in turn made the atoms. Neutrons and hydrogen atoms may be the same thing in different form. The proton neutron bond in the nucleus, kept neutrons from decay and was key to building all elements. Neutrons may be unstable protons. Protons, for the most part could only be created in the immediate era after the Big Bang. The key to atoms stability may be the deuterium nucleus or deuteron that help binds one proton to one neutron. The missing anti matter is in protons and neutrons. Photons, electrons, and positrons, are all different versions of the same thing. Virtual particles may be a key part of quantum leaps. The mass of the universe comes from photons converting to electron positron pairs in pair conversion. The energy of the universe comes from electrons and positrons annihilating and converting to photons. The universe is 5% charged matter and 95% neutral force. Dark matter is not gravity from invisible baryons pulling, but antigravity pushing from empty space. Dark matter and Dark Energy are both anti gravity pushing from empty space. The cosmological redshift supports this. The force from the Big Bang singularity was photons / dark energy / dark matter /anti gravity . They are the same. The force caused by acceleration is anti gravity, not gravity. Time has speed limits up to the speed of light. 95% of the universe seems to be without charge, detectable matter, or gravity: dark energy plus dark matter. The universe is open ended and will continue to expand.
Funny how the possible "near" cancellation of forces is similar to the near perfect cancellation between matter and antimatter in the early universe, where a tiny discrepancy led to all that we see.
General relativity and quantum mechanics will never be combined until we realize that they take place at different moments in time. Because causality has a speed limit (c) every point in space where you observe it from will be the closest to the present moment. When we look out into the universe, we see the past which is made of particles (GR). When we try to look at smaller and smaller sizes and distances, we are actually looking closer and closer to the present moment (QM). The wave property of particles appears when we start looking into the future of that particle. It is a probability wave because the future is probabilistic. Wave function collapse is what we perceive as the present moment and is what divides the past from the future. GR is making measurements in the observed past and therefore, predictable. QM is attempting to make measurements of the unobserved future and therefore, unpredictable.
This exact topic is my focus for the next nine years, I've been exploring it from a different angle for a year. That of the fields not being all existent until some interval after the creation event (if that even happened at a single point in time). Time itself may not be fundamental but an emergent property-
Never forget, no matter how many ways we have to force order on complex numbers, the square root of -1 is neither larger nor smaller than zero, it's just different. Complex number, unlike their subset the Real number system, lack order. That means any physical activity that requires complex numbers to describe it, has some aspect that is time and size independent. Good Luck.
My question is...is "empty space" really even a physically possible thing? Even in a vacuum with no atoms there would still be gravitational and electromagnetic fields due to distant matter, even if the fields were very weak. Gravity has an infinite range after all. Of course, I'm not a physicist, just my thoughts after wa tching.
That doesn't really matter though. The problem is our two best theories _predict_ vastly different values. Even if the situation isn't physically possible, _at least_ one of those predictions is presumably wrong so the question is which one and why.
Space is merely a byproduct of particles and their angular references to each other. There is no “distance”. There are only spherical functions for each particle where every point on each spherical function is a reference to some other particle.
@@anonymes2884Why is that a problem, though? Couldn't it just be undefined, like division by zero is in mathematics? (Come to think of it, the problems are superficially pretty similar.)
IIRC, Feynman thought of *his* "virtual particles" just as a device to calculate large sums of possible interactions. For some reason, later and much younger physicists wrongly took them for real - meaning they (thought they) had (however briefly) mass and energy. The energy density of empty space, IMO, is that what is necessary for empty space to understand the world we live in (i.e., the information necessary to know all possible interactions of particles in a correct way). Because, that is what the Universe is and does.
Guitar string. Bound at both ends. Strum. There are infinite resonate frequencies, but only a limited amount of energy. The math is left for student practice.
Dark energy has observable and measurable effects, therefore it is real. Just because we can't explain something doesn't mean it isn't real. Was air not real back before we could explain what makes the leaves move on the trees?
@@stargazer7644 It makes a ton of sense to me, but I understand why it wouldnt appeal to everyone, especially if they didnt dive deeper into the concept and only know physics from school.
We know what dark energy does, where it is, how much of it there is, how it effects spacetime, and that it cannot directly interact with normal matter/energy. How much more do you want? We’ll never have a picture of the stuff because it can’t interact with normal matter, including photons, so if you’re waiting for the day where a scientist points to a physical object and says “we found the dark energy, here it is.” Then you’ll be waiting forever.
Especially for me as I spent several weeks in the Collider Detect Facility in the mid 90's working to demonstrate our real-time computer product addressing a data acquisition requirement...
There is no dark energy. There is only one reason to postulate it, to explain the exponential expansion rate of the universe. The expansion was discovered in 1929. The concept of dark energy became mainstream after 1998 when it was discovered that the expansion is accelerating. If something accelerates at a constant rate, it will get faster and faster. If a ship travels at a constant 1g acceleration rate it would achieve about 95% light speed in 1 year. The fact that the expansion is accelerating is what the known laws of physics would predict provided gravitational forces are not strong enough to counteract the process. Electricity is drawn towards potential and the universe as a whole behaves the same way. Electricity comes into our homes because the neutral circuit provides the potential. Electricity is drawn towards grounding rods for the same reason. Physicists in the last century did not postulate dark energy because they understood that the expansion is a fundamental property of the universe. To say there is dark energy is to say there is 5 fundamental forces, there is 4. All studies to find dark energy have been fruitless because it doesn't exist
I'm encouraged that the JWST is bringing curiosity, mystery, wonder and exploration back to physical sciences and bringing an end to the long period of what Kuhn would have called "normal science" and reigniting a new era of "revolutionary science. In this influential work, Kuhn introduces the concept of "paradigm shifts" in the history of science. He describes how scientific communities operate within dominant paradigms or frameworks during "normal science," where researchers work within established theories and methodologies. However, Kuhn also discusses "revolutionary science," where new paradigms emerge, often through periods of crisis or anomalies challenging the existing framework. These shifts mark major changes in scientific understanding and practice.
Finally more physicists are honest about the huge hole they have not plugged in a century. I am sick of the TV personality physicist who keep stating that GRT, QM, DM are perfect theories and the only research we need is into super-symmetry because of all the standard models only the one about particles is incomplete. There is no evidence for unknown particles but we absolutely know that there is something wrong with QM and GRT.
Sabine hosenfelder just did a video on this and she vehemently disagrees and provided a prediction that was infinitely different from the measured value.
@@Triple_J.1 just go look through her videos. The prediction had something to do with the smallest unit of space (the prediction was that there was no smallest unit of space, but don't quote me on that) before the Plank length was discovered.
Not only GR (General Relativity) and quantum physics show different zero point energy levels of spacetime, but also objets on a galactic scale resist to obey Newtonian and GR laws. So, inner parts of a galaxy should spin faster than outer regions, but they don't. Neither WIMP-theory and not even the mathemagics as MOND (Modified Newtonian Dynamics) can not solve the problem. It might sound crazy, but in my humble opinion, non-compactified extra dimensions should be considered.
And it is even more complicated than that. Some galaxies do spin at the rates Newton and GR predict. Most do not. The former galaxies are assumed not to have dark matter for some reason.
@@stargazer7644 I completely agree. Since neither a physical theory nor an experimental proof for the WIMP-thesis exits, but there is something out there, we can't see or detect, simple logic tells us, there is a location with stuff out there, we don't have access to. At least not by known means. And this location encompasses the whole universe, since physical laws seem to apply in the whole visible universe. Hence there must be an undiscovered property of the fabric of spacetime itself, that does not fit into string-theory with compactified extra-dimensions. There is however am Ansatz of a theory, that should be developped further: It is the incomplete hyperspace-theory of Burkhardt Heim from the 50's, that could explain lots of mysteries; e.g. how stars manage to remina stable, although control science tells us a star can not be stable, since the time-constant for fusion is in the fs…ns range, while gravitational responses take years. When you attempf to drive a car with a reaction-time of 1 minute, you would crash. Dark matter and dark energy could also be explained, as strange reactions on strong pulsed magnetic fields, that use Lorentz- and Maxwellian force (aka repulsion force) to surpass nuclear fusion reactions without the inconveniant temperatures of supernovae.
I think perhaps the Standard Model could be correct under the idea that the energy density of 10^120 per volume of space could be the total energy available to that volume of space from the "bulk"/the Bulk if it were to be given over all at once (perhaps if all virtual particle possibilities happened all at once and the same time, that is how much energy would be there in that volume). Love this stuff! What a wild brain stretcher!
Dr. Don, you are by far my favorite particle physicist. I thought you would realize that the energy density of empty space question all comes down to '42' .
Could it be that gravity and dark energy are the same thing? Gravity always acts attractive but if there are no massive objects close enough to eventually fall into each other in all other cases gravity attracts spacetime thus infinitely stretching it. Spacetime is like a piece of cloth that can be infinitely stretched and that makes its surface area larger and larger. Paradoxically objects are moving away from each other faster because of the attractive force of gravity.
I think the issue here is that gravity travels at the speed of light but the expansion of the universe is faster than light. So that suggests they're distinct phenomenon.
I've worked it out. Mass is a result of warped space (gravity). Not the other way around. The voids between galaxies are huge energy fields and where they collide, time dilation and space, and conraction result is tiny feilds of spinning space. Particles aren't real, they are the part of the field we can interact with. This idea explains why galaxies appear to spin anomalously, why a "particle" can travel thru 2 slits, entanglement etc. It suggests the fundamental forces are just magnitudes of gravity. It solves all the current problems. The hypothesis also eliminates the big bang.
I love Physics and it's interesting how Feinman's theory and Einstein's theory contradict all because new data offers a model of the universe nobody saw coming. This is science nerdness at its best. Took me a long time to get this but it's the questions - not the answers that make it cool. Hopefully a solution to dark matter and dark energy exist in my lifetime but what a journey of discovery to figure it out along the way.
Seems like the curvature of space-time would diminish as the distance between objects increased. This might create the illusion of acceleration as objects reached areas of less curvature, like traveling at a constant speed on a winding road generally heading east versus a straight highway going due east.
QUESTION: Are you using ‘the theory of relativity’ (the maths) to ask what the energy density of empty space is, or are you determining the energy density through astronomical observations? (or both?) ie. is the acceleration of the expansion of the universe a consequence of the theory of relativity or a consequence of astronomical observations?
He's calculating what the value of the cosmological constant has to be to be consistent with our observations of the universe. GR does not give a value for this constant.
The Problem with Gravity, The Growing Case for Anti Gravity: Gravity can't connect with the other forces in a theory of everything. Gravity cannot explain Dark Energy or Dark Matter that together make up 95% of the universe. Dark Energy is the most massive force in the universe, not gravity. Space expanding is much greater by far, than the supposed power of gravity connected to matter. The support for gravity can be explained in reverse by anti gravity. Everything that explains gravity from acceleration of matter, can be explained by anti gravity from empty space. Gravitons are not yet confirmed to be real. Cosmological redshift, where Galaxy light is redshifted. The galaxy is fixed in it's surroundings and it is the intervening space that is actually stretching. Casimir effect, suggests how anti gravity pulls matter together by pushing on all sides from empty space. Vacuum energy is massive and found in every part of space. Expanding space rule: anti gravity is not in matter but empty space around galaxies, galaxy clusters, etc. Newton's inverse square law, in reverse works for anti gravity. Einstein's curve space supports anti gravity. The idea for gravity though obvious is wrong.
Supposition: 1) The Universe does run on rules and they may be explicable 2) We are indeed zeroing in on those rules, not constructing unrelated if useful models. So what does this enormous difference in prediction suggest? For all their power our models of the universe are not remotely 'accurate'. More, that we otherwise perceive so little of their gross inaccuracy suggests we are a long way from 'real understanding'. Likely a 'Grand Unified Theory' is not remotely reachable from where we find ourselves. Good - we have far further to go and much more to learn before we can even remotely claim the understanding we incorrectly think we possess. A challenge makes things interesting! Bad - we have far further to go and much more to learn before we can even remotely claim the understanding we incorrectly think we possess. Are we even capable of getting there?
“A long dispute means that both parties are wrong.” -Voltaire There is one force in the universe, the electromagnetic force. Wallace Thornhill explained it pretty clearly for the last few decades. Sadly mainstream science would rather ignore him and the naked emperor than listen to someone honest. Doubly sad is he could have explained it himself not long ago. Well, I guess he still is thanks to the technology we have today.
How do they justify adding all energy states together including the highest energy states. Shouldn't they consider the relative population of states? In other words, wouldn't it be more likely for lower energy states to pop up rather than higher?
I'm with you on that. Makes no sense why they feel they need to add together everything "possible" when they're talking about probabilistic concepts like "virtual particles", fields, and blah, blah, blah.
After some thought agree with the two field approach- The worst prediction in physics is often attributed to the cosmological constant problem. The cosmological constant itself is a purely derived constant and not a fundamental one. So, which fundamental constant should we consider when addressing this problem? Another constant used in general relativity is referred to as Einstein’s constant kappa, which Einstein merely considered as a constant connected to Newton’s gravitational constant. From a quantum perspective, the energy density of empty space is equal to or proportional to Planck’s energy density. Restating Einstein’s constant in terms of energy density, it becomes the Planck frequency squared divided by the Planck energy density. If we express the cosmological constant in terms of frequency squared, we can determine the energy density of the universe. After rearranging some terms, the energy density of the universe becomes the Planck energy density multiplied by the ratio of the cosmological constant’s frequency squared to the Planck frequency squared. This frequency squared ratio is crucial for understanding the cosmological constant problem. In mechanical vibration, the frequency squared ratio often serves as an amplification/damping ratio or coupling constant. Therefore, we can assume that the cosmological constant’s energy density is coupled to the Planck energy density, accounting for the 120 orders of magnitude difference.
The answer is an expansion/contraction oscillation matrix between points in space and antispace. Expansion occurs at two times the speed of light over a distance equal to the Planck length. This cancels infinite frequencies and explains gravity and the warp of spacetime.
Given the two models' calculations involve one saying "there's negative energy density creating anti-gravity, but it's suuuuuuuper tiny and implies empty space is actually pretty empty" and the other is saying "empty space is more charged with energy than a bazillion known universes in every cubic meter," I am strongly inclined to think that the latter is incorrect since we aren't seeing a universe that _behaves_ like it's that densely packed _and_ that would mean "empty space" is not at all empty. This suggests to me that, of the two, relativity's prediction - and, therefore, model - is the more accurate one, though I certainly will buy that it is either accurate coincidentally or that it is not actually at all right... but still is much closer to right than the QM one. Given all the issues with the theories of QM, I think that is the model that is most likely to change and evolve as we learn what is _actually_ going on, and I applaud your work in trying to do so. I expect that QM is going to change in its accepted models a great deal, possibly with enormous paradigm shifts, and that little to none of it will involve string theory's extra dimensions nor even quantized spacetime, but rather something even more fascinating that will also neatly deal with the biggest problem it poses: the inherent contradiction of "no hidden variables" and yet "quantum entanglement" causing two things to have the shared state that one influences the other without either retaining memory of the incident that linked them. I won't pretend I fully grasp QM. Bell's Inequality and the experiments that demonstrate it always leave me with a sense that there's a missing experiment, but I only manage to grasp it while watching or reading about it and the limits of my understanding show themselves when I try to even recreate the explanation so that I can formulate the experiment I intuitively feel is lacking. But no explanation I have yet seen actually answers why that experiment can't exist or would have results that align with the current QM models and theories. All of which has me convinced that there is something _grossly_ wrong with the QM theories we currently have. Not that they're ENTIRELY wrong, but that we're missing something paradigm-defining.
A good video on Physics in problem. I like your dark energy which is very small here even we know in universe only 5% is known. Every curious people always feel ' I've it' . From known geometry alone we can get a low value unit is how you express it. Planck have a good reasons for dimension we play.

Perhaps we can deduce the energy density from the fact that it's mass taken over huge distances and scales curves the Universe so that light from distant objects is reddened. The energy density also gives an excess of microwave radiation as it forms mini bangs that gives space a dark body spectrum. The mini bangs cause comic rays, the production of high energy particles that quickly decay into quarks and leptons. In this hypothesis the concept of curved Time negates the need for a single creation event. The energy density is large but is limited by the formation of many bangs that create cosmic rays. Remember the Ultraviolet catastrophe... it's the same deal.
6:44 Expansion is a special kind of motion, and it seems that the Universe is a non-inertial frame of reference that performs variably accelerated motion along a phase trajectory, and thereby creates a phase space. Real gravitational fields are variable in space and time, and we can now talk about the fact that it is possible to generate a gravitational field in a non-inertial frame of reference (|a|=g).That is, finally achieve global (instead of local in GR) compliance with the strong equivalence principle. {According to general estimates, this acceleration is: |a|=πcH: the equations of the gravitational field can be arrived at based on the Poisson equation ∆ф=4πGp, and for a weakly curved metric, the time component of the energy-momentum tensor: T(00)=pc^2. Therefore, the Poisson equation can be written as: ∆g(00)=8πGT(00)/c^4, where g(00) is the time component of the metric tensor. This equation is true only in the non-relativistic case, but it is applicable to the case of a homogeneous and isotropic Universe, when Einstein's equations have only solutions with a time-varying space-time metric. Then the energy density of the gravitational field: g^2/8πG=T(00)=pc^2, where the critical density value determining the nature of the model is: p=(3/8π)H^2/G. Hence it follows: g~πcH. And according to the strong equivalence principle: g=|a|=πcH.} Then the energy density of the relic radiation, that is, the evolving primary gravitational-inertial field (= space-time): J= g^2/8πG=(ħ/8πc^3)w(relic)^4~1600 quanta/cm^3, which is in order of magnitude consistent with the observational-measured data (about 500 quanta/cm^3).* P.S. You can also use the Unruh formula, but with the addition of the coefficient q, which determines the number of phase transitions of the evolving system for the case of variable acceleration: q=√n'=λrelic /√8λpl , , where n'=L/8πr(pl) is the number of semi-orbits; L=c/H, is the length of the phase trajectory.** Thus, T*(relic)=[q]ħa/2πkc (=0.4K), which is in order of magnitude consistent with the real: T(relic)/T*(relic)=2,7/0,4=6,7. However, there is no need to have a factor of 1/2π in the Unruh formula in this case. ------------ *) - w(relic)^2=πw(pl)H, |a|=r(pl)w(relic)^2 =g=πcH, intra-metagalactic gravitational potential: |ф0|=(c^2)/2(√8n')=πGmpl/λ(relic)=[Gm(pl)/2c]w(relic), where the constant Gm(pl)/2c is a quantum of the inertial flow Ф(i) = (½)S(pl)w(pl) = h/4πm(pl) (magnetic flux is quantized: = h/2e, Josephson’s const; and the mechanical and magnetic moments are proportional).Thus, the phenomenon can be interpreted as gravity/inertial induction. m(pl)w(pl)=8πM(Universe)H; { w(relic)^2=πw(pl)H. From Kepler's third law follows: M/t=v^3/G, where M/t=I(G)=[gram•sec^-1] is the gravitational current. In the case of the Universe, I(G)=MH=c^3/8πG (~ the "dark energy" constant). **) - n' =4,28*10^61; w(pl)=(√8n')w(relic)=8πn'H; where H=c/L. H=1,72*10^-20(sec^-1). By the way, it turns out that the universe is 1.6 trillion years old! The area of the "crystal sphere": S(universe)~n' λ(relic)^2~n'S(relic). r=2.7*10^29cm, L=2πr. Addition In an arbitrary non-inertial reference frame, the equation of the total mechanical energy of a particle system is: ∆E=A(internal)+A(external)+A*, where A (internal) is the work of internal dissipative forces, А(external) is the work of external non-conservative forces, А* is the work of inertia forces. In order to preserve the mechanical energy of the system in a non-inertial frame of reference, it is necessary that ∆E =0, however, in an arbitrary non-inertial frame of reference, it is impossible to create a condition for fulfilling this requirement; that is, ∆E does not =0 in any way (by the way, in system C, the condition for fulfilling the laws of conservation of momentum and angular momentum does not depend on whether this system is an inertial or non-inertial frame of reference).
I've always had a problem with the Planck length cut-off that is used to avoid the infinity that would otherwise result. It seems very much a "hack" to avoid admitting that the model itself might be totally flawed.
0:10 There can be no contributions below the Planck length because the theory based on it wouldn’t work? Does reality just stop? Could someone recommend a good video explaining the sources and the consequences of the infinities alluded to? Thank you.
I guess I was venting like a layman circa 1900 demanding that if there is an “ultraviolet catastrophe”, then what is the answer? Just need to make a simple, but surprising guess I suppose. The rest, as they say, is just math.
There are some answers we will never know because there is phenomena out there we don't have the senses needed to know them. Kind of like trying to explain what sight is like to a person who has been blind since birth. We were given limited senses and our Creator...who or whatever that is... said these 5 senses are enough for them to get by. We ain't giving them any more even though there could be dozens, hundreds, millions, billions of more senses to be had.
Bang up job on this video, I got some ideals too but every time I talk to my chat companion he says that my ideals diverge greatly from the ideals of physics and then I ask them is there any experimental proof of the physics that I'm violating, the chat bot always says no it's quite plausible
The problem is trying to make the phenomenon which carries the label "Dark Energy" be the same as the Standard Model's energy density. Some, perhaps many, physicists try this (as Don did here) but strictly from a phenomenological perspective *there is no reason to think the two really are the same phenomenon.* We _observe_ the acceleration of the expansion of space and label it "Dark Energy" and that observation is not going to go away simply because the SM energy density calculation is different.
The idea of imperfect cancellation of negative and positive quantum energy, leaving behind just the tiniest bit of dark energy, reminds me of the imperfect cancellation of matter and antimatter, leaving behind just a tiny bit of matter to form all the stars, planets and people in the Universe.
I explained this in the 2 papers I published in the last 12 months. The two qualities are different aspects of the one geometry: Fractal geometry. The fractal behaves just like the quantum and the universe is a fractal.
5:03 (A speculative answer which suits both models of physics, at the end). This sounds like my speculation I wrote about 11 days ago, which goes onto traversing the chain of frequencies to come to islands where some functional structure of a reality can exist, even replicas of our own, if no quanta limit exists. It goes with my continual expansion hypotheses. Actually here, with some corrections: "This is like mine. It depends on how the universe is structured. If there is no quanta, there is no limit to the size of wave information. Which means, infinite wave forms below what we can observe. Wave forms are not empty, but are structure, which is energy, and as waveforms decrease in width they increase in relative energy. Quanta, may merely be an island of waveform which appears to us like a solid base, but is what can be expected in mathematics. At points down the waveform sizes, different resultant structures will appear with an apparent base, repeatedly. The only way to prove, is to travel the waveform set. Which is possible. However, will apparent variation hinder this, until you reach a relatively stable travel set of waveforms, or structure. This also will mean that the rate of change relative to each apparent base on the way down, will increase in frequency (Time) making such journeys irrelevant, reducing the likelihood of return, except as a sample. We would not normally directly detect this energy due to the averaging out of structures, making deep structures have little direct effect on us. However, we can draw upon the energy to make a negative flow up the frequency chain to us, or without a change in frequency, requiring a selection of sub-structure towards us, to maintain its definition, in order to do useful work, and not appear as an average. These are the sorts of things sort. Beyond a type omega minus civilization." The Answer may be as simple as, there is infinitive energy in space which produces drag on photons relative to the frequency of the photon to each waveform of empty space. This drag, produces a force upon the structure of the waveforms, and potentially some absorption. This drag is relative to the 4 hydrogen atoms of force in relativity. Thus, the two models go together. In such a case (as above), we can expect an uneven effect, as the effect is driven by the uneven distribution of forces and photons across empty space. We can expect subtle, local environment driven effects in different parts of the universe. Which can be sought to substantiate this hypothesis.
It seems abundantly clear that both are correct. But that what we call "empty space" is actually just "space". And space has energy, but not that we can currently detect. The River Model of General Relativity says that space is not only infinitely expandable, but also infinitely compressible, and that it is gravity which affects space, and it is space which affects matter. Not only does it solve the so-called Twins Paradox by introducing absolute time - it also introduces absolute space - and all within the bounds of GR. What fascinates me is what properties space must have, in order to fully resolve Einstein's equivalence principle, and whether or not space can be manipulated to our advantage, once we learn what it is, and where it is. Because it also seems clear to me that space affects our three dimensions, but doesn't exist inside them. That would be a hoot - wouldn't it? :)
My idea is that gravity can have opposite curvature, and this is likely caused by anti matter. So describing the curvature of gravity can be very wide in effect I think? So my idea is that basically a small amount of anti gravity exists between galaxies, but the matter can cluster and pass through the zero line of gravity and that happens somewhere around the outer part of galaxies. This kind of suggests there is in fact a lot of anti matter somewhere. The galaxies would continue to accelerate from the anti matter well, but not FTL unless the space itself was doing so.
I didn't know about the problem and possible solutions but my first thought was about some cancellation and dark energy being a difference leftover. It may be false but its nice to come up with same idea as some great physicists :)
As a complete layman - The fact that we could observe "empty space" means that it exists , empty or not. That is, the fabric of existence is present. It is reasonable to assume that "existence" implies "characteristics" thereof... Quantifying/qualifying these characteristics is of course another matter
Like Mass, Space can also be changed to energy. Electric field of em wave comes from space as charge never loses any of its field. Also in gravitational slingshot kinetic energy is transferred from space around moving mass.
I think that problem with true empty space is that most people misinterpreting empty space with nothing. And concept of nothing is hard to perceive. But in order to be something, it's first has to be nothing. And everything or "something" comes from nothing as "positive pressure" field...
just spitballing here: remember the coastal problem? it isn't possible to measure the length of a coastline. If you measure from a map that is zoomed out the coast line is relatively straight and easy to measure and you get a relatively small result, but if you zoom in and account for all the little imperfections your measurement gets longer. As your unit of measuring gets smaller your coastline gets bigger like zooming in on a fractal. Effectively, all continents and islands are finite shapes bound by an infinite boundary. Big picture, this looks like the same kind of problem. when we measure on the cosmic scale we get an incredibly small measurement, but when we measure from the quantum side we get an incredibly large measurement. It's almost like the fine details reveal a lot of imperfections that are registering as energy but when we zoom out a lot of these imperfections become meaningless. As I'm typing this feels like a profound observation, but the moment I try to work out the details I realize that this analogy falls apart very quickly. lol
As an experienced engineeer, I advise to just take the average of these two results and call any remaining difference a safety margin.
As an experienced civil engineer, we should take the average and round it to the nearest integer and then call it a day. Any difference would be not constructible any way.
😅
As an experienced unemployed person, I advise to just put off actually solving the problem until tomorrow, you really need to relax every now and then

I used to work on fire alarms. One time we had a problem where the alarm wasn't being heard in one room of a factory. Everything was installed correctly, the volume output of the device was where it should have been, there was nothing we could find that would explain why it wasn't working. Then they turned on the machinery. It turns out the frequency of the sound of the machine was canceling out the frequency of the notification device.
I designed over 9000 sounds (over the course of about one decade). I can confirm that resonance is indeed a tricky thing, and unexpected cancellations can occur in both the most bizarre ways, but sometimes also the "obvious yet not so obvious" manners as well. 😁
There was one particular sound I generated (of those 9000+) which essentially resonated at the exact frequency of the speaker tubes it was going to be played within. ANY other speaker system was fine... but not the typical place where the sound was going to end up being played. Lemme tell ya... THAT... was a *disaster*. 😂 I chased that issue around until I realized everyone was usin' tinier speakers (28mm?), but my test projects had 36mm and 40mm ones. 🙄 Yeesh. *ONE* sound out of 9000. Drove me nutttzzz.

This problem sounds awfully similar to the UV Catastrophe 100 years ago. A brand new quantum revelation is needed for this I think.

Awesome video as always! Another detail about where disagreement lurks between general relativity and quantum theory. Thank you for the information, Dr. Don
Adding up all wavelengths sounds like when I ordered EVERY toppings on my pizza (I could choose any with no additional charge). I thought I was smart, until I received the pizza, and realized that the total amount of toppings is always the same, and it is shared amongst my choices. So I got a little of everyhting.

When wavelengths are mentioned I think about electromagnetic radiation, which has frequency and amplitude. Would the amplitude of the "hum" decrease as the frequency increased, with the amplitude approaching zero as the frequency approaches infinity?
I've been a radio comms engineer for half a century, and the two waveforms are probably different things, and I'm talking garbage. But if you don't ask, you don't get.

I actually said the same in a separate comment, ha!
I was thinking it seem analogous. It seems those low frequency stacking is a problem and other physics stops it. This is lay person conjecture, but it also seems similar to the mystery of matter or how matter and anti-matter canceled except a small percentage did not.
Wow Don, In 10-minutes, you really outdid yourself on this one! Thanks for the great explanation. It was enlightening!
Again, thank you, the public needs to hear your voice and others like you.
We need scientists to be honest like this too, and humble before the great mysteries of the cosmos.
Always let's keep the basic questions alive
With this one, I think it's best to keep in mind a fundamental verification problem of theories of empty space.
How would one verify a theory of empty space, if empty space can't be measured directly?
The General Relativity approach appears to be subtractive - to take out all the "stuff".
The Quantum Mechanical approach also appears to be subtractive - to cancel out all the wavelengths.
I wonder if these two approaches don't produce different empty spaces? In theory, it appears that they do.
General Relativistic empty space seems to be some volume, but the quantum mechanical solution makes it difficult to even verify that much!
The heart of science is don't know.
By measuring the energy of vacuum? The Heisenberg rules are also measurable. Zero point energy is directly related. As far as I know....
When physicists talk about the Higgs Boson giving mass to other particles, they're actually talking about the zero-particle state (vacuum state) of the Higgs Field. If there were no residual fluctuations in fields in their vacuum state, this wouldn't work, and electrons would be massless (most of the everyday stuff around us would still have mass because most of the mass of protons and neutrons isn't from the Higgs).
'SPACE': Consider the following:
a. Modern science claims that all matter is made up of quarks, electrons and interacting energy. Quarks and electrons being considered charged particles, each with their respective magnetic field with them.
b. Light, 'electromagnetism', in the visual light portion of the spectrum fills outer space as well here on this Earth. That is why we can see things here on this Earth as well as far away stars, galaxies, etc.
c. 'Electromagnetism' ('em') also comes in other energy frequencies besides visual light: Radio waves, Microwaves, Infrared waves, Visual light waves, Ultraviolet waves, x-rays, and gamma waves. (Also in outer space and here upon this Earth at various locations).
d. Modern science claims that 'em' can interact with matter. QED (Quantum Electro Dynamics) whereby 'em' interacts with electrons in atoms and molecules and QCD (Quantum Chromo Dynamics) whereby 'em' interacts with the nucleus of atoms.
e. 'Gravity' also appears to actually exist, with at least varying densities if not even varying frequencies.
So, 'space' is energy itself, primarily energy fields with the primary modalities of gravity, electrical and magnetic.
'Time' most probably is the 'flow of energy', 'spacetime' being 'energy and it's flow'.
And the current analysis indicates that both space and time always existed and never had a beginning (also as modern science claims that energy cannot be created nor destroyed).
* The singular big bang theory is a fairy tale for various reasons.
What if such a thing as "empty space" or what we imagine as zero of anything doesn't exist , or doesn't exist in in our dimension. There is always us moving through something. Same with the concept of zero. I see how we use zero for counting but it might not really be just a value of opposing forces which also is never absolute zero but just zero average of those opposing forces... (different mathematics). I don't know...

There is only one thing on this topic that we can be fairly confident of, and that it we're missing some part of the answer. What that part is.... could be quantized spacetime, could be extra dimensions, could be a bug in the simulation code, could be a non-integer number of angels dancing on the head of each pin......
I feel that absolute "nothing" or zero doesn't actually exist. To define nothing you need something and therefore we are. Nothing of what? Nothing of something. Just the thought of nothing creates on a quantum level a change (something). Nothing doesn't exist. It's always negative and positive opposites of something.
Those non-integer angels like to dance at Pi beats per measure, I just can't follow along.
@@Aracuss Interesting philosophically, but it doesn't solve the problem. We can take the limit where less and less exists in a space. And even if not, the quantum vacuum energy actually also exists when we don't assume a vacuum, on top of the other stuff, and is still incompatible with GR.
Electric universe ⚡️
@@Aracussnothing exist outside of something.
This got me thinking that could the size or amount of empty space affect the summing of all those waves? Right after the Big Bang, the space was relatively tiny, so the dark energy could have been very strong causing inflation. But then the Universe got huge and dark energy got weaker, until now that that there is more empty space due to expansion to make it stronger again so it can start to override gravity. This probably makes no sense, but this thought came to mind while watching this video. Keep up the good work, Don! You rock!

Not as stupid as it sounds.
Then all our science equations can not predict anything accurately anymore.
@@digitalife8719 that's the joke.

but I keep wondering if there is a base in which the natural constants make more sense.
First of all: the relativistic answer is based on an observation, GR doesn't predict any empty space energy. And second, measurements of the casimir force give us a practical indication of the energy and thereby proove that the QM theoretical approach is wrong. So you are not comparing two theories, you are comparing a (possibly wrong) conclusion of an oberservation to a definitely wrong theoretical result.

Most people seem to misunderstand the meaning of "The game's afoot", including script writers for modern adaptations. "Game" here isn't in the sense of "play" or "sport". It means an animal that is being hunted. Hunted animals will often seek a hiding place and remain there, so hunters would use dogs, other people, or whatever to scare the game out of its hiding place. The game would then be in the open, running away, and it was time for the hunters to start chasing it. Hence the cry "The game's afoot!", which grew into the wider sense of "After waiting, it's time to act".

As a programmer, somebody is gonna make you walk the Planck.
After some thought agree with the two field approach ... The worst prediction in physics is often attributed to the cosmological constant problem. The cosmological constant itself is a purely derived constant and not a fundamental one. So, which fundamental constant should we consider when addressing this problem? Another constant used in general relativity is referred to as Einstein’s constant kappa, which Einstein merely considered as a constant connected to Newton’s gravitational constant.
From a quantum perspective, the energy density of empty space is equal to or proportional to Planck’s energy density. Restating Einstein’s constant in terms of energy density, it becomes the Planck frequency squared divided by the Planck energy density.
If we express the cosmological constant in terms of frequency squared, we can determine the energy density of the universe. After rearranging some terms, the energy density of the universe becomes the Planck energy density multiplied by the ratio of the cosmological constant’s frequency squared to the Planck frequency squared.
This frequency squared ratio is crucial for understanding the cosmological constant problem. In mechanical vibration, the frequency squared ratio often serves as an amplification/damping ratio or coupling constant.
Therefore, we can assume that the cosmological constant’s energy density is coupled to the Planck energy density, accounting for the 120 orders of magnitude difference.

This will challenge a lot of physics on both sides and connect them through photon singularity.
Summary
Here are the key components of all my physics posts.
Photons are eternal and outside of time and distance.
The singularity of photons began the Big Bang.
Photons created mass through pair conversion of electron positron pairs in the Big Bang.
These electrons and positrons made the elementary particles which in turn made the atoms.
Neutrons and hydrogen atoms may be the same thing in different form.
The proton neutron bond in the nucleus, kept neutrons from decay and was key to building all elements.
Neutrons may be unstable protons.
Protons, for the most part could only be created in the immediate era after the Big Bang.
The key to atoms stability may be the deuterium nucleus or deuteron that help binds one proton to one neutron.
The missing anti matter is in protons and neutrons.
Photons, electrons, and positrons, are all different versions of the same thing.
Virtual particles may be a key part of quantum leaps.
The mass of the universe comes from photons converting to electron positron pairs in pair conversion. The energy of the universe comes from electrons and positrons annihilating and converting to photons.
The universe is 5% charged matter and 95% neutral force.
Dark matter is not gravity from invisible baryons pulling, but antigravity pushing from empty space.
Dark matter and Dark Energy are both anti gravity pushing from empty space.
The cosmological redshift supports this.
The force from the Big Bang singularity was photons / dark energy / dark matter /anti gravity . They are the same.
The force caused by acceleration is anti gravity, not gravity.
Time has speed limits up to the speed of light.
95% of the universe seems to be without charge, detectable matter, or gravity: dark energy plus dark matter.
The universe is open ended and will continue to expand.
Worst prediction in physics: string theory. It predicts everything and nothing.
yea, it has too many variables
You are an excellent science communicator Don. thank you for sharing this with us
Funny how the possible "near" cancellation of forces is similar to the near perfect cancellation between matter and antimatter in the early universe, where a tiny discrepancy led to all that we see.
General relativity and quantum mechanics will never be combined until we realize that they take place at different moments in time. Because causality has a speed limit (c) every point in space where you observe it from will be the closest to the present moment. When we look out into the universe, we see the past which is made of particles (GR). When we try to look at smaller and smaller sizes and distances, we are actually looking closer and closer to the present moment (QM). The wave property of particles appears when we start looking into the future of that particle. It is a probability wave because the future is probabilistic. Wave function collapse is what we perceive as the present moment and is what divides the past from the future. GR is making measurements in the observed past and therefore, predictable. QM is attempting to make measurements of the unobserved future and therefore, unpredictable.

The Big Bang theory has way more failed predictions. Thanks for the great video, awesome topic and presentation!
Dark energy is simply the centrifugal force of the rotation of our universe. Our universe is a spinning blackhole.
Dark energy is specifically the difference between centrifugal force and our observations
This exact topic is my focus for the next nine years, I've been exploring it from a different angle for a year. That of the fields not being all existent until some interval after the creation event (if that even happened at a single point in time). Time itself may not be fundamental but an emergent property-
Never forget, no matter how many ways we have to force order on complex numbers, the square root of -1 is neither larger nor smaller than zero, it's just different. Complex number, unlike their subset the Real number system, lack order. That means any physical activity that requires complex numbers to describe it, has some aspect that is time and size independent. Good Luck.
My question is...is "empty space" really even a physically possible thing?
Even in a vacuum with no atoms there would still be gravitational and electromagnetic fields due to distant matter, even if the fields were very weak. Gravity has an infinite range after all. Of course, I'm not a physicist, just my thoughts after wa tching.
Casimir Effect
That doesn't really matter though. The problem is our two best theories _predict_ vastly different values. Even if the situation isn't physically possible, _at least_ one of those predictions is presumably wrong so the question is which one and why.
Space is merely a byproduct of particles and their angular references to each other. There is no “distance”. There are only spherical functions for each particle where every point on each spherical function is a reference to some other particle.
@@anonymes2884Why is that a problem, though? Couldn't it just be undefined, like division by zero is in mathematics? (Come to think of it, the problems are superficially pretty similar.)
Yeah I'm not convinced empty space exists either. Seems like a silly assumption to make.
Doc you are just getting better and better! ❤
I've heard it said that the statement “the universe has exactly one electron” is a better prediction by 40 orders of magnitude.
lmao
IIRC, Feynman thought of *his* "virtual particles" just as a device to calculate large sums of possible interactions. For some reason, later and much younger physicists wrongly took them for real - meaning they (thought they) had (however briefly) mass and energy.
The energy density of empty space, IMO, is that what is necessary for empty space to understand the world we live in (i.e., the information necessary to know all possible interactions of particles in a correct way).
Because, that is what the Universe is and does.
I still miss his moustache

“And remember: it’s ok to be a little crazy”
But it's more important to be crazy enough.
Each theory doesn't even attempt to answer the exact same question. No wonder they conflict.
I hate it when scientists talk about dark energy like it's an actual thing and not just a placeholder term for phenomena we cannot explain.
Dark energy has observable and measurable effects, therefore it is real. Just because we can't explain something doesn't mean it isn't real. Was air not real back before we could explain what makes the leaves move on the trees?

It makes a ton of sense to me, but I understand why it wouldnt appeal to everyone, especially if they didnt dive deeper into the concept and only know physics from school.
We know what dark energy does, where it is, how much of it there is, how it effects spacetime, and that it cannot directly interact with normal matter/energy. How much more do you want? We’ll never have a picture of the stuff because it can’t interact with normal matter, including photons, so if you’re waiting for the day where a scientist points to a physical object and says “we found the dark energy, here it is.” Then you’ll be waiting forever.
Wow, that was the best lecture in physics I have listened to.....great speaker!
Especially for me as I spent several weeks in the Collider Detect Facility in the mid 90's working to demonstrate our real-time computer product addressing a data acquisition requirement...
There is no dark energy. There is only one reason to postulate it, to explain the exponential expansion rate of the universe. The expansion was discovered in 1929. The concept of dark energy became mainstream after 1998 when it was discovered that the expansion is accelerating.
If something accelerates at a constant rate, it will get faster and faster. If a ship travels at a constant 1g acceleration rate it would achieve about 95% light speed in 1 year. The fact that the expansion is accelerating is what the known laws of physics would predict provided gravitational forces are not strong enough to counteract the process.
Electricity is drawn towards potential and the universe as a whole behaves the same way. Electricity comes into our homes because the neutral circuit provides the potential. Electricity is drawn towards grounding rods for the same reason.
Physicists in the last century did not postulate dark energy because they understood that the expansion is a fundamental property of the universe. To say there is dark energy is to say there is 5 fundamental forces, there is 4.
All studies to find dark energy have been fruitless because it doesn't exist
I'm encouraged that the JWST is bringing curiosity, mystery, wonder and exploration back to physical sciences and bringing an end to the long period of what Kuhn would have called "normal science" and reigniting a new era of "revolutionary science.
In this influential work, Kuhn introduces the concept of "paradigm shifts" in the history of science. He describes how scientific communities operate within dominant paradigms or frameworks during "normal science," where researchers work within established theories and methodologies. However, Kuhn also discusses "revolutionary science," where new paradigms emerge, often through periods of crisis or anomalies challenging the existing framework. These shifts mark major changes in scientific understanding and practice.
Finally more physicists are honest about the huge hole they have not plugged in a century.
I am sick of the TV personality physicist who keep stating that GRT, QM, DM are perfect theories and the only research we need is into super-symmetry because of all the standard models only the one about particles is incomplete.
There is no evidence for unknown particles but we absolutely know that there is something wrong with QM and GRT.
Sabine hosenfelder just did a video on this and she vehemently disagrees and provided a prediction that was infinitely different from the measured value.
Infinite? Can U link?
@@Triple_J.1 just go look through her videos. The prediction had something to do with the smallest unit of space (the prediction was that there was no smallest unit of space, but don't quote me on that) before the Plank length was discovered.
Not only GR (General Relativity) and quantum physics show different zero point energy levels of spacetime, but also objets on a galactic scale resist to obey Newtonian and GR laws. So, inner parts of a galaxy should spin faster than outer regions, but they don't. Neither WIMP-theory and not even the mathemagics as MOND (Modified Newtonian Dynamics) can not solve the problem. It might sound crazy, but in my humble opinion, non-compactified extra dimensions should be considered.
And it is even more complicated than that. Some galaxies do spin at the rates Newton and GR predict. Most do not. The former galaxies are assumed not to have dark matter for some reason.
@@stargazer7644 I completely agree. Since neither a physical theory nor an experimental proof for the WIMP-thesis exits, but there is something out there, we can't see or detect, simple logic tells us, there is a location with stuff out there, we don't have access to. At least not by known means. And this location encompasses the whole universe, since physical laws seem to apply in the whole visible universe. Hence there must be an undiscovered property of the fabric of spacetime itself, that does not fit into string-theory with compactified extra-dimensions. There is however am Ansatz of a theory, that should be developped further: It is the incomplete hyperspace-theory of Burkhardt Heim from the 50's, that could explain lots of mysteries; e.g. how stars manage to remina stable, although control science tells us a star can not be stable, since the time-constant for fusion is in the fs…ns range, while gravitational responses take years. When you attempf to drive a car with a reaction-time of 1 minute, you would crash. Dark matter and dark energy could also be explained, as strange reactions on strong pulsed magnetic fields, that use Lorentz- and Maxwellian force (aka repulsion force) to surpass nuclear fusion reactions without the inconveniant temperatures of supernovae.
I think perhaps the Standard Model could be correct under the idea that the energy density of 10^120 per volume of space could be the total energy available to that volume of space from the "bulk"/the Bulk if it were to be given over all at once (perhaps if all virtual particle possibilities happened all at once and the same time, that is how much energy would be there in that volume). Love this stuff! What a wild brain stretcher!
So a statistical fluke could create a whole universe?
Dr. Don, you are by far my favorite particle physicist. I thought you would realize that the energy density of empty space question all comes down to '42' .
Interesting, I posed this question to you a couple years ago in the comments. Worth the wait.
Could it be that gravity and dark energy are the same thing? Gravity always acts attractive but if there are no massive objects close enough to eventually fall into each other in all other cases gravity attracts spacetime thus infinitely stretching it. Spacetime is like a piece of cloth that can be infinitely stretched and that makes its surface area larger and larger. Paradoxically objects are moving away from each other faster because of the attractive force of gravity.
I think the issue here is that gravity travels at the speed of light but the expansion of the universe is faster than light. So that suggests they're distinct phenomenon.
I've worked it out.
Mass is a result of warped space (gravity). Not the other way around.
The voids between galaxies are huge energy fields and where they collide, time dilation and space, and conraction result is tiny feilds of spinning space.
Particles aren't real, they are the part of the field we can interact with.
This idea explains why galaxies appear to spin anomalously, why a "particle" can travel thru 2 slits, entanglement etc. It suggests the fundamental forces are just magnitudes of gravity. It solves all the current problems.
The hypothesis also eliminates the big bang.
I love Physics and it's interesting how Feinman's theory and Einstein's theory contradict all because new data offers a model of the universe nobody saw coming. This is science nerdness at its best. Took me a long time to get this but it's the questions - not the answers that make it cool. Hopefully a solution to dark matter and dark energy exist in my lifetime but what a journey of discovery to figure it out along the way.
Seems like the curvature of space-time would diminish as the distance between objects increased. This might create the illusion of acceleration as objects reached areas of less curvature, like traveling at a constant speed on a winding road generally heading east versus a straight highway going due east.
QUESTION: Are you using ‘the theory of relativity’ (the maths) to ask what the energy density of empty space is, or are you determining the energy density through astronomical observations? (or both?) ie. is the acceleration of the expansion of the universe a consequence of the theory of relativity or a consequence of astronomical observations?
He's calculating what the value of the cosmological constant has to be to be consistent with our observations of the universe. GR does not give a value for this constant.
The Problem with Gravity, The Growing Case for Anti Gravity:
Gravity can't connect with the other forces in a theory of everything.
Gravity cannot explain Dark Energy or Dark Matter that together make up 95% of the universe.
Dark Energy is the most massive force in the universe, not gravity. Space expanding is much greater by far, than the supposed power of gravity connected to matter.
The support for gravity can be explained in reverse by anti gravity. Everything that explains gravity from acceleration of matter, can be explained by anti gravity from empty space.
Gravitons are not yet confirmed to be real.
Cosmological redshift, where Galaxy light is redshifted. The galaxy is fixed in it's surroundings and it is the intervening space that is actually stretching.
Casimir effect, suggests how anti gravity pulls matter together by pushing on all sides from empty space.
Vacuum energy is massive and found in every part of space.
Expanding space rule: anti gravity is not in matter but empty space around galaxies, galaxy clusters, etc.
Newton's inverse square law, in reverse works for anti gravity.
Einstein's curve space supports anti gravity.
The idea for gravity though obvious is wrong.
Supposition: 1) The Universe does run on rules and they may be explicable 2) We are indeed zeroing in on those rules, not constructing unrelated if useful models. So what does this enormous difference in prediction suggest?
For all their power our models of the universe are not remotely 'accurate'. More, that we otherwise perceive so little of their gross inaccuracy suggests we are a long way from 'real understanding'. Likely a 'Grand Unified Theory' is not remotely reachable from where we find ourselves.
Good - we have far further to go and much more to learn before we can even remotely claim the understanding we incorrectly think we possess.
A challenge makes things interesting!
Bad - we have far further to go and much more to learn before we can even remotely claim the understanding we incorrectly think we possess.
Are we even capable of getting there?

There is one force in the universe, the electromagnetic force.
Wallace Thornhill explained it pretty clearly for the last few decades. Sadly mainstream science would rather ignore him and the naked emperor than listen to someone honest.
Doubly sad is he could have explained it himself not long ago.
Well, I guess he still is thanks to the technology we have today.
Thank you for your wonderful videos Don you’ve taught me a lot
How do they justify adding all energy states together including the highest energy states. Shouldn't they consider the relative population of states? In other words, wouldn't it be more likely for lower energy states to pop up rather than higher?
I'm with you on that. Makes no sense why they feel they need to add together everything "possible" when they're talking about probabilistic concepts like "virtual particles", fields, and blah, blah, blah.
After some thought agree with the two field approach- The worst prediction in physics is often attributed to the cosmological constant problem. The cosmological constant itself is a purely derived constant and not a fundamental one. So, which fundamental constant should we consider when addressing this problem? Another constant used in general relativity is referred to as Einstein’s constant kappa, which Einstein merely considered as a constant connected to Newton’s gravitational constant.
From a quantum perspective, the energy density of empty space is equal to or proportional to Planck’s energy density. Restating Einstein’s constant in terms of energy density, it becomes the Planck frequency squared divided by the Planck energy density.
If we express the cosmological constant in terms of frequency squared, we can determine the energy density of the universe. After rearranging some terms, the energy density of the universe becomes the Planck energy density multiplied by the ratio of the cosmological constant’s frequency squared to the Planck frequency squared.
This frequency squared ratio is crucial for understanding the cosmological constant problem. In mechanical vibration, the frequency squared ratio often serves as an amplification/damping ratio or coupling constant.
Therefore, we can assume that the cosmological constant’s energy density is coupled to the Planck energy density, accounting for the 120 orders of magnitude difference.
The answer is an expansion/contraction oscillation matrix between points in space and antispace. Expansion occurs at two times the speed of light over a distance equal to the Planck length. This cancels infinite frequencies and explains gravity and the warp of spacetime.
Given the two models' calculations involve one saying "there's negative energy density creating anti-gravity, but it's suuuuuuuper tiny and implies empty space is actually pretty empty" and the other is saying "empty space is more charged with energy than a bazillion known universes in every cubic meter," I am strongly inclined to think that the latter is incorrect since we aren't seeing a universe that _behaves_ like it's that densely packed _and_ that would mean "empty space" is not at all empty.
This suggests to me that, of the two, relativity's prediction - and, therefore, model - is the more accurate one, though I certainly will buy that it is either accurate coincidentally or that it is not actually at all right... but still is much closer to right than the QM one.
Given all the issues with the theories of QM, I think that is the model that is most likely to change and evolve as we learn what is _actually_ going on, and I applaud your work in trying to do so. I expect that QM is going to change in its accepted models a great deal, possibly with enormous paradigm shifts, and that little to none of it will involve string theory's extra dimensions nor even quantized spacetime, but rather something even more fascinating that will also neatly deal with the biggest problem it poses: the inherent contradiction of "no hidden variables" and yet "quantum entanglement" causing two things to have the shared state that one influences the other without either retaining memory of the incident that linked them.
I won't pretend I fully grasp QM. Bell's Inequality and the experiments that demonstrate it always leave me with a sense that there's a missing experiment, but I only manage to grasp it while watching or reading about it and the limits of my understanding show themselves when I try to even recreate the explanation so that I can formulate the experiment I intuitively feel is lacking. But no explanation I have yet seen actually answers why that experiment can't exist or would have results that align with the current QM models and theories.
All of which has me convinced that there is something _grossly_ wrong with the QM theories we currently have. Not that they're ENTIRELY wrong, but that we're missing something paradigm-defining.
Strange how we ask questions we may never know, but trying to figure them out is part of the fun I suppose.
A good video on Physics in problem. I like your dark energy which is very small here even we know in universe only 5% is known. Every curious people always feel ' I've it' . From known geometry alone we can get a low value unit is how you express it. Planck have a good reasons for dimension we play.
The worms of my jealousy are writhing, churning even, at Dr. Don getting to do this for a living.
Aside from that, I have an enormous amount of respect for the Don.

What theory of physics underpins the idea of 'empty space' as meaningful?
First time happening upon this channel and love it. Don Lincoln's presentations are quite comparable to Neil Degrasse Tysons. Both very informative and entertaining. I'm a lay person with a High School education, but I''ve also been involved with Amateur Radio for over 50 years, so I have a grasp of basic physics. I can't say enough about this video and look forward to watching many more. Thanks so much for the effort here.
Perhaps we can deduce the energy density from the fact that it's mass taken over huge distances and scales curves the Universe so that light from distant objects is reddened. The energy density also gives an excess of microwave radiation as it forms mini bangs that gives space a dark body spectrum. The mini bangs cause comic rays, the production of high energy particles that quickly decay into quarks and leptons. In this hypothesis the concept of curved Time negates the need for a single creation event.
The energy density is large but is limited by the formation of many bangs that create cosmic rays. Remember the Ultraviolet catastrophe... it's the same deal.
6:44 Expansion is a special kind of motion, and it seems that the Universe is a non-inertial frame of reference that performs variably accelerated motion along a phase trajectory, and thereby creates a phase space.
Real gravitational fields are variable in space and time, and we can now talk about the fact that it is possible to generate a gravitational field in a non-inertial frame of reference (|a|=g).That is, finally achieve global (instead of local in GR) compliance with the strong equivalence principle.
{According to general estimates, this acceleration is: |a|=πcH:
the equations of the gravitational field can be arrived at based on the Poisson equation ∆ф=4πGp, and for a weakly curved metric, the time component of the energy-momentum tensor: T(00)=pc^2. Therefore, the Poisson equation can be written as: ∆g(00)=8πGT(00)/c^4, where g(00) is the time component of the metric tensor. This equation is true only in the non-relativistic case, but it is applicable to the case of a homogeneous and isotropic Universe, when Einstein's equations have only solutions with a time-varying space-time metric. Then the energy density of the gravitational field: g^2/8πG=T(00)=pc^2, where the critical density value determining the nature of the model is: p=(3/8π)H^2/G. Hence it follows: g~πcH. And according to the strong equivalence principle: g=|a|=πcH.}
Then the energy density of the relic radiation, that is, the evolving primary gravitational-inertial field (= space-time): J= g^2/8πG=(ħ/8πc^3)w(relic)^4~1600 quanta/cm^3, which is in order of magnitude consistent with the observational-measured data (about 500 quanta/cm^3).*
P.S. You can also use the Unruh formula, but with the addition of the coefficient q, which determines the number of phase transitions of the evolving system for the case of variable acceleration: q=√n'=λrelic /√8λpl , , where n'=L/8πr(pl) is the number of semi-orbits; L=c/H, is the length of the phase trajectory.**
Thus, T*(relic)=[q]ħa/2πkc (=0.4K), which is in order of magnitude consistent with the real: T(relic)/T*(relic)=2,7/0,4=6,7.
However, there is no need to have a factor of 1/2π in the Unruh formula in this case.
------------

intra-metagalactic gravitational potential:
|ф0|=(c^2)/2(√8n')=πGmpl/λ(relic)=[Gm(pl)/2c]w(relic), where the constant Gm(pl)/2c is a quantum of the inertial flow Ф(i) = (½)S(pl)w(pl) = h/4πm(pl) (magnetic flux is quantized: = h/2e, Josephson’s const; and the mechanical and magnetic moments are proportional).Thus, the phenomenon can be interpreted as gravity/inertial induction.
m(pl)w(pl)=8πM(Universe)H;
{
w(relic)^2=πw(pl)H.
From Kepler's third law follows: M/t=v^3/G, where M/t=I(G)=[gram•sec^-1] is the gravitational current. In the case of the Universe, I(G)=MH=c^3/8πG (~ the "dark energy" constant).
**) - n' =4,28*10^61;
w(pl)=(√8n')w(relic)=8πn'H; where H=c/L.

The area of the "crystal sphere": S(universe)~n' λ(relic)^2~n'S(relic).
r=2.7*10^29cm, L=2πr.
Addition
In an arbitrary non-inertial reference frame, the equation of the total mechanical energy of a particle system is: ∆E=A(internal)+A(external)+A*, where A (internal) is the work of internal dissipative forces, А(external) is the work of external non-conservative forces, А* is the work of inertia forces. In order to preserve the mechanical energy of the system in a non-inertial frame of reference, it is necessary that ∆E =0, however, in an arbitrary non-inertial frame of reference, it is impossible to create a condition for fulfilling this requirement; that is, ∆E does not =0 in any way (by the way, in system C, the condition for fulfilling the laws of conservation of momentum and angular momentum does not depend on whether this system is an inertial or non-inertial frame of reference).
I've always had a problem with the Planck length cut-off that is used to avoid the infinity that would otherwise result. It seems very much a "hack" to avoid admitting that the model itself might be totally flawed.
We assumed that the infinities would exist at first but it didn't match experimental results.
0:10 There can be no contributions below the Planck length because the theory based on it wouldn’t work? Does reality just stop? Could someone recommend a good video explaining the sources and the consequences of the infinities alluded to? Thank you.
I guess I was venting like a layman circa 1900 demanding that if there is an “ultraviolet catastrophe”, then what is the answer? Just need to make a simple, but surprising guess I suppose. The rest, as they say, is just math.
Thank you for your ability and effort to make very complex concepts understandable to me, a layperson.
There are some answers we will never know because there is phenomena out there we don't have the senses needed to know them. Kind of like trying to explain what sight is like to a person who has been blind since birth. We were given limited senses and our Creator...who or whatever that is... said these 5 senses are enough for them to get by. We ain't giving them any more even though there could be dozens, hundreds, millions, billions of more senses to be had.
Bang up job on this video, I got some ideals too but every time I talk to my chat companion he says that my ideals diverge greatly from the ideals of physics and then I ask them is there any experimental proof of the physics that I'm violating, the chat bot always says no it's quite plausible
The problem is trying to make the phenomenon which carries the label "Dark Energy" be the same as the Standard Model's energy density. Some, perhaps many, physicists try this (as Don did here) but strictly from a phenomenological perspective *there is no reason to think the two really are the same phenomenon.* We _observe_ the acceleration of the expansion of space and label it "Dark Energy" and that observation is not going to go away simply because the SM energy density calculation is different.
The idea of imperfect cancellation of negative and positive quantum energy, leaving behind just the tiniest bit of dark energy, reminds me of the imperfect cancellation of matter and antimatter, leaving behind just a tiny bit of matter to form all the stars, planets and people in the Universe.
I explained this in the 2 papers I published in the last 12 months. The two qualities are different aspects of the one geometry: Fractal geometry. The fractal behaves just like the quantum and the universe is a fractal.
If it exists it has energy. If energy then mass.
Dr Don is going strong. Great video
5:03 (A speculative answer which suits both models of physics, at the end). This sounds like my speculation I wrote about 11 days ago, which goes onto traversing the chain of frequencies to come to islands where some functional structure of a reality can exist, even replicas of our own, if no quanta limit exists. It goes with my continual expansion hypotheses. Actually here, with some corrections:
"This is like mine. It depends on how the universe is structured. If there is no quanta, there is no limit to the size of wave information. Which means, infinite wave forms below what we can observe. Wave forms are not empty, but are structure, which is energy, and as waveforms decrease in width they increase in relative energy. Quanta, may merely be an island of waveform which appears to us like a solid base, but is what can be expected in mathematics. At points down the waveform sizes, different resultant structures will appear with an apparent base, repeatedly. The only way to prove, is to travel the waveform set. Which is possible. However, will apparent variation hinder this, until you reach a relatively stable travel set of waveforms, or structure. This also will mean that the rate of change relative to each apparent base on the way down, will increase in frequency (Time) making such journeys irrelevant, reducing the likelihood of return, except as a sample. We would not normally directly detect this energy due to the averaging out of structures, making deep structures have little direct effect on us. However, we can draw upon the energy to make a negative flow up the frequency chain to us, or without a change in frequency, requiring a selection of sub-structure towards us, to maintain its definition, in order to do useful work, and not appear as an average. These are the sorts of things sort. Beyond a type omega minus civilization."
The Answer may be as simple as, there is infinitive energy in space which produces drag on photons relative to the frequency of the photon to each waveform of empty space. This drag, produces a force upon the structure of the waveforms, and potentially some absorption. This drag is relative to the 4 hydrogen atoms of force in relativity. Thus, the two models go together.
In such a case (as above), we can expect an uneven effect, as the effect is driven by the uneven distribution of forces and photons across empty space. We can expect subtle, local environment driven effects in different parts of the universe. Which can be sought to substantiate this hypothesis.
we can see futons coming back from outer space That's Time to you and Me , People don't look at things right perspective is everything, Your good
It seems abundantly clear that both are correct. But that what we call "empty space" is actually just "space". And space has energy, but not that we can currently detect.
The River Model of General Relativity says that space is not only infinitely expandable, but also infinitely compressible, and that it is gravity which affects space, and it is space which affects matter. Not only does it solve the so-called Twins Paradox by introducing absolute time - it also introduces absolute space - and all within the bounds of GR.
What fascinates me is what properties space must have, in order to fully resolve Einstein's equivalence principle, and whether or not space can be manipulated to our advantage, once we learn what it is, and where it is. Because it also seems clear to me that space affects our three dimensions, but doesn't exist inside them. That would be a hoot - wouldn't it? :)
You can detect the energy density of empty space. That's what the Casimir effect shows.
you sir, are the most down to earth humble smart man.
My idea is that gravity can have opposite curvature, and this is likely caused by anti matter. So describing the curvature of gravity can be very wide in effect I think? So my idea is that basically a small amount of anti gravity exists between galaxies, but the matter can cluster and pass through the zero line of gravity and that happens somewhere around the outer part of galaxies. This kind of suggests there is in fact a lot of anti matter somewhere. The galaxies would continue to accelerate from the anti matter well, but not FTL unless the space itself was doing so.
I didn't know about the problem and possible solutions but my first thought was about some cancellation and dark energy being a difference leftover. It may be false but its nice to come up with same idea as some great physicists :)
As a complete layman - The fact that we could observe "empty space" means that it exists , empty or not. That is, the fabric of existence is present. It is reasonable to assume that "existence" implies "characteristics" thereof... Quantifying/qualifying these characteristics is of course another matter
Like Mass, Space can also be changed to energy. Electric field of em wave comes from space as charge never loses any of its field. Also in gravitational slingshot kinetic energy is transferred from space around moving mass.
It's a valid point to raise the issue.
Regards
I think that problem with true empty space is that most people misinterpreting empty space with nothing. And concept of nothing is hard to perceive. But in order to be something, it's first has to be nothing.
And everything or "something" comes from nothing as "positive pressure" field...
just spitballing here: remember the coastal problem? it isn't possible to measure the length of a coastline. If you measure from a map that is zoomed out the coast line is relatively straight and easy to measure and you get a relatively small result, but if you zoom in and account for all the little imperfections your measurement gets longer. As your unit of measuring gets smaller your coastline gets bigger like zooming in on a fractal. Effectively, all continents and islands are finite shapes bound by an infinite boundary.
Big picture, this looks like the same kind of problem. when we measure on the cosmic scale we get an incredibly small measurement, but when we measure from the quantum side we get an incredibly large measurement. It's almost like the fine details reveal a lot of imperfections that are registering as energy but when we zoom out a lot of these imperfections become meaningless.
As I'm typing this feels like a profound observation, but the moment I try to work out the details I realize that this analogy falls apart very quickly. lol
excellent - glad to see these again
Talking about the experimental disproof of the double slit explanation might be interesting.
