    "Electromagnetic Fields and Waves" by Lorrain & Corson (2nd Edition) contains two problems relating Electrodynamics and Cosmology. Problem 4-22 starts with: "In 1959 Lyttelton and Bondi [Proc. Roy. Soc. (London) A, vol. 232, p.313] suggested that the expansion of the Universe could be explained on the basis of Newtonian Mechanics if matter contained a [tiny] net electric charge."
    A follow-on problem, Problem 10-11, mentions that correction terms to curlB and divE due to the creation of this charge should be on the order of R^-2 where R is on the order of the radius of the Universe, so that the new terms would be negligible at all length scales but cosmological situations. This hypothesis is consistent with the linear velocity-distance observations.
    Rather thought-provoking questions from an Undergraduate E&M textbook!

      Dark matter is the right answer. The problem is we have no reliable explanations as to what dark matter actually is because we cannot interact with it. And MOND continues to fall apart in the time since this video came out. It makes sense to continue studying dark matter because we can observe its effects. Something is definitely there. We need to figure out what it is

    Great video! I'm an amateur astronomer/astrophotographer and very interested in these topics and try to stay up on the latest developments. I've long had questions around this topic that I've never been able to truly find good answers. I've always been more of a MOND fan than DE/DM due to the fact that, as I understand, these are mear values inserted into equations to make them work so they match the observations. I love your open mindset where I've seen other videos where they take a hard stance on there is DM/DE and we just have to find it.
    I've thought a lot about this and have read articles on things like "Warp Drive", etc. which talk about bending space on either side of a starship. This made me think that we really don't understand how to interact with space. We understand that spacetime is a thing, and can see how the presence of matter can "bend" it to explain gravitational attraction. At least, that's the assumption of how it works. I've also read about quantum theories on particles like gravitons that do this interaction, yet, no evidence has been found to support this. I've read about string theory, etc., which tries to explain some of this. However, what if we simply don't fully understand the nature of space itself? Is it possible that it's just a property of space that it has to expand much like a balloon in a vaccum where the fact that there's no barrier at the edge of our universe to stop it and it simply must grow to fill the void? Is there a difference between space and a void where spacetime doesn't exist? What if we treated space as a separate physical construct that doesn't require particles to explain? I've noticed that they are always searching for a physical particle to explain such theories but never seem to contemplate the notion that spacetime has more properties that are yet to be defined?
    Can the equations that use the values for DE/DM be used in such a way to explain these properties? The thing that makes this make sense to me is the variance in red shift for more distant objects and explains the observation that the universe seems to be expanding in all directions away from us while accelerating. Perhaps this rate of expansion can be quantified and used in these equations. So when you're calculating the spin of a galaxy, are you also allowing for this expansion of space within the galaxies? Have we measured the rate of expansion between objects within the Milky Way? It has to happen everywhere if it's true. We wouldn't see it within very close proximity of a gravity field such as us walking on the earth or even between here and the moon. It would be only very slight between objects closer to the center, but more noticeable on the outer rim where things are much farther apart. We should see stars in the outer parts of our galaxy sort of pushing each other away very slightly because of the distance of space between them expanding if this were true.
    Ok, I've probably outdone myself on the crackpot scale, but would appreciate any further discussion to better understand these ideas. If I'm totally off base, I'd appreciate that feedback as well. These are just questions I have that keep me up at night. Thank you!

    Question: in a simulation of a three body system, usually one of the objects flings out of the system, and the other two become stable around each other. A chaotic as the system is, this is usually what happens (other than stable solutions). Now when we model formation of galaxies with dark matter, which makes it match the observations better, does the model consider that some dark matter must fling out of the system for everything else to become stable?

    Some commenters have said that DM is wrong. I wonder what information, observations, or theories allowed them to come to that conclusion. But they could be right about DM being wrong. Two problems I see are that DM "measurements" are post-hoc, i.e. they look at the mass of all the visible matter and calculate how much DM must be present to account for the motion of the stars in a galaxy or the movement of galaxies in a cluster, so they cannot see DM they cannot predict what the motions will be, rather they must measure the motions and determine the mass of dark matter. The other problem is that physicists have not idea of where DM fits into the Standard Model, and I'm not sure any have come up with a hypothesis of where DM fits, or with an alternative Model that explains everything the Standard Model explains while also explaining DM. So is there a more massive particle that has not been discovered yet? Probably a reason to build a MUCH more powerful collider.

    Awesome that mathematical models based on the philosophically untenable paradigm of chronocentric atomism have taken us this far.
    Fix that … and explaining the various phenomena for which DM is required … becomes quite trivial, as does understanding why the mathematical models of QM and GR work where they do.
    Physics though, is focused on mathematical models,not what regular people call Theories (understanding of mechanism).
    Note that Copernicus' model of planetary motions did not offer better predictions than did epicyclic models. It did simplify the picture though and advanced our understanding of mechanism.
    Escaping geocentricism required observations of the phases of Venus. Not better predictions.
    Escaping the current paradigm … should have happened long ago, but physics has firewalled itself very effectively, and has way more mathematical objects with which to tweak their mathematical models than did the poor epicyclists, who just had circles.
    End chronocentricism. Invert atomism. Insist on simplicity … it really isn't that hard ;)

Could you include current thinking on the cause of inflation and if it ended or could dark energy just be a remnant of it. Thanks.

    The problem I see with so many thought experiments is that they begin with a host of unexamined assumptions, the most glaring being what consciousness is. A lot of scientists suppose that consciousness arises from matter, but from the non-dualist perspective, it is the other way around. Also, often concepts like consciousness, thought, mind, ego, identity - all get muddled together and are not sorted out. The terms are then used interchangeably when they are distinct concepts. Another flaw I see is the assumption that for every single quantum result, the assumption is being made that everything in existence is being duplicated on a macro level and then continues onward. And so what? Maybe it is just consciousness, or awareness, or the non-dualistic nature of reality that is simply experiencing ALL material possibilities. We are sadly limited in our localized consciousness and struggle to process this view of the universe, it does not sit well with our ego-centric view of reality. Just another thought experiment with unexamined assumptions.
    Here's a thought experiment: if MWT is correct and for every single quantum interaction a parallel world exists, so what? Because if the Universe is infinite then everything in all forms exists. Infinity necessarily includes everything.
    My complaint with the Many Worlds Theory is that it is not empirically verifiable. That does not mean it is wrong, just that we will never know if it is correct. So what good does it do us on any practical level? It seems like a scientific dead end to me - but it's great for metaphysical conversations.

However, if I was looking for dark matter and I had come up empty after decades I would put my full effort into approaching it through the back door. What is the ‘origin’ of dark matter? What is the rationale for its existence to provide all of these observations? Why would dark matter have the properties that it does? If does dark matter exist than it ‘has to’ exist. It’s not the rotation just of galaxies , etc that need dark matter to explain their properties but fundamental physics at the time of Inflation, etc need dark matter to be logical.

    I personally suspect that dark matter is correct but it isnt actually within our universe as we assume, it sort of overlaps, acting as if the other side of the sheet in the demonstration of a mass pulling in gravity. A particle which is outside our reality but is still influenced by the quantum fields of our universe and thus mass and it interact with eachother in the field but not in the physical.
    Alternatively if string theory holds true, perhaps what we are observing are extradimensional particles.
    I suppose that we do not see them not because they are rare or hard to see but because we cannot see them. We cannot currently observe with certainty that which may be beyond our universe and we cannot see that which exists physically in a higher or lower dimension.

    Dark matter is the source of superconductivity. At 2.72K, photons pass through it and it generates the cosmic microwave background. This is why all light from stars is observed in the red shift. Using the Planck constant and e=mc^2, it calculates a mass of 1.181 X 10^-39 kg. This mass fits into the mass discrepancies of the atom, both the missing mass and the “empty” volume. It is responsible for electromagnetism, the weak force, the strong force and the motions of the stars & planets. We do not have 4 fundamental forces, we have 1 fundamental force, in which dark matter is the source of, that we are able to observe in 4 different states/configurations.

    If dark matter has a large impact on the gravity of a galaxy, would you say that it permeates the galaxy? If so, wouldn't the Earth be bathed in dark matter to some degree? Then wouldn't dark matter be contributing to the gravitational constant G? But to what degree? When we thought G was only due to the matter we know about, how could we tell what proportion of it was also due to dark matter? Is dark matter distributed unevenly throughout a galaxy? If so, then G would be different in different places in the galaxy. Since G is determined experimentally, and the only place we've run the experiment is on Earth, then variations could happen elsewhere. This could really shake things up, but it could also be used to explain galaxy rotation. But why would dark matter be unevenly distributed? For the same reason regular matter is, I suppose. Maybe the uneven distributions are the result of the interplay between the two forms of matter. There is much to contemplate.

    You may ask why am I so off track, well, recently we are beginning to understand some eerie nature of reality though not confirmed but no other way to explain it. These are; the situation argument, space and time is doomed, consciousness being fundamental in nature etc. If you actually look at it what we call normal matter is indeed the odd matter because it makes a smaller amount of matter in the universe. So who knows the next bottle neck we bomb into.

    Just a question... perhaps more about your choice of words than what physicist specialists use... Right about 5 minutes in, you say that dark matter doesn't interact with light.
    But earlier, you say that some of the evidence FOR dark matter comes from gravitational lensing, which to my mind by definition means *interaction*. So which is it?
    I don't know because I'm not trained. (Just an engineer making measurement instrumentation for scientists.) But I think because you mention gravitational lensing earlier, that you were mistaken when around at 5 minutes in you say that it does NOT interact with light.
    So I'm just chalking this up to loose talk in a video (I can't cast any stones -- guilty too) and I'm going with "Yes, dark matter interacts with light -- at least, it does so in a gravitational meaning as it is expressed when the general theory of relativity is deduced into specific situations that produce mathematical calculations which can be tested by observational, experimental result."

And when incomplete particle gets enough energy it produces gravitational gradient around it. and it gets devoured by complete particles but it is not enough for anything, except when thermonuclear synthesis happens it cannot happen without these incomplete particles.

I feel there is other layers to gravity once you get to immense scales like on the scale of entire galaxies and multiple galaxies interacting and many multiple galaxies interacting with all the properties of, density's, temperature's, velocity's, static charges, electromagnetism, plasma, Etc. All interacting with each other, and then it gets even bigger than that. I do not feel we actually have the ability to comprehend and accurately calculate this type of nature of the universe. So maybe there is a small scale gravity, average level gravity, and a Large scale gravity layer? It's just a hypothetical idea I have.

    • @mattpotter8725
      @mattpotter8725 Рік тому

      I have often thought the same. Not quite that there are different forces of gravity at different scales but much like Einstein's equations for General Relativity predicted that as objects American the speed of light, relativistic speeds, they are subject to effects that affect their mass or even the perception of the universe around them, then at large enough scales similar coefficients or extra term need to be added to Newton's Laws of Gravity.
      The fact that we don't have Quantum Theory for Gravity is problematic, which makes me think that we just don't understand gravity well enough. I don't like the Dark Matter explanation. It may be true, but to me it seems like something we'll never be able to prove beyond circumstantial evidence, which for me is like how before Einstein came up with his Theory of Special Relativity all physicists were including aether to make all their proposed theories fit the experimental results.
      I personally don't think there is a silver bullet answer that will explain everything here, hence why we've found it hard to find an easy solution. It may be, in my opinion, a combination of many things we don't yet know. But particles that don't interact with anything else (light of matter), but have mass and this exert a gravitational effect only interacting with space time curvature just sounds very far fetched, even if it is the most likely explanation. As a true scientist I'm skeptical of either proposed solution until the evidence is there to prove either correct.

      Gravity has an equal opposite counterpart called energy. To move matter against the pull of gravity an equal opposite amount of energy is required. Even more energy is required for the same matter to reach an escape velocity. Energy is required to cause galaxies to move away from each other against the pull of their gravity. Energy is the action, motion or gravity is the reaction.
      Gravity is what happens to matter that is unable to produce energy to counter the effects of gravity, cancel out the gravity so to speak. So a boulder is attracted to the Earth because it doesn't radiate enough energy to counter the Earth's gravity. Expansion of space between objects happens when the objects produce an excess of energy against the pull of their gravity. Example, you have two stars radiating a constant solar wind full of hot charged particles at 2 million miles per hour and the two stars will not collide. Well, as long as they are not on a direct trajectory or path towards one another. When they are not on the same trajectory their solar winds will force them apart. This is the equal opposite action causing their gravity.
      Energy is the action and motion is the reaction. Gravity is described as motion of mass. Mass is radiating energy producing motion we call gravity. When energy is created deep in the cores of large spherically shaped objects, gravity becomes the equal opposite counterpart, causing small matter to be attracted. But if both of the objects are radiating a constant flow of energy then a repulsive reaction occurs. Energy flowing upon small objects produces an attraction and the energy flowing upon large objects produces a repulsive force. The direction of motion then is determined by the object radiating energy and the objects receiving the energy. Attraction and repulsion occurs.
      Can this be proven in experiments? Yes, it has. Research ion lifters. When energy radiates from the metal causes them to defy gravity. Also research ARV, alien reproduction vehicle.

Normal matter formed at the great recombination epoch, a couple of hundred thousand years after the BB. Strangely, we see no evidence that antimatter also formed at the same time, although our models suggest that an equal amount of antimatter and normal matter should have been produced. Now, what if there is some reason that we have yet to discover that antimatter can not form by the process of recombination, but instead what should have been antimatter turns out as dark matter instead. Kind of like unborn matter. Matter that failed to recombine during that epoch. And there's more of it now that normal matter because a lot of normal matter has since turned into energy in stars.

Образно говоря, из-за указанного взаимодействия диск галактики приобретает некоторую связку, становится "жестче", и потому линейная скорость вращения отдаленных частей диска возрастает. ... Если представить себе, что диск галактики (со всеми его внутренностями) стал жестким, то имеющаяся вращательная энергия диска перераспределится так, что угловая скорость вращения жесткого диска станет меньше, при этом уменьшится и линейная скорость вращения ближней к центру вращения части диска, а линейная скорость дальних от центра вращения частей диска еще больше увеличится.

    Do you know of anyone who has seriously persued the notion of "We have the standard candles/measurements to them incorrect" and these galaxies are smaller than recorded? This may avoid invention of any new matter or any modifications to existing laws, just adjusting the scales and measurements to fit the observable result?

      No offence, but suggesting measurement errors is like saying to the surgeon, hey did you know you can transplant one kidney? ;) Check the Wikipedia page on dark matter, especially the observational evidence part.

      None taken, the offense is all sciences, however I guess this means the answer to my question is no? The reason I ask is that you are comparing Astrophysics to Medical Surgery using an analogy about something mankind has its hands on and has had the opportunity to examine, versus something vastly completely unknown.
      "Check the Wikipedia page on dark matter, especially the observational evidence part."
      If you are acting like stating the obvious has already happened, then please point me to any resources to look at where someone has actually proposed it could be a measurment mismatch issue and not a change in Newtonian Dynamics at certain scales or introducing unobservable matter? You will see on wiki there is no mention of the scale issue hence why MOND and Dark Matter are the primary propositions. Of which to add, there is no obsverational evidence for dark matter at all, there is only a consequential effect which we have assumed is a new form of exotic unknown matter, hence the question.
      I do not know where you see my other comment shouting out Jan Oort and Kent Ford but please do assume I had read much more deeper than just the wiki page on the topic, especially when the wiki page confirms the primary reason here "The primary evidence for dark matter comes from calculations". Now you can take that as an incomplete cherry pick if you need to, but that would be avoiding the very point of me asking the question.

      ​@@Gleem 1) Looking for errors and refining measurements is the bread and butter in astronomy. Also, see the distance ladder on Wikipedia. I can't point you to any research, but on top of my head, I recall ongoing attempts to refine the Hubble constant, which is related.
      2) There are 11 observational phenomena explained by DM and described in Wikipedia. Some of which could be explained only with large quantities of invisible and inert matter such as predicted DM.

      @@pavel9652 1/. Hubble constant has a massive issues at the moment which has increased the "crisis" of cosmology already beyond dark matter and dark energy. I know of one scientist who did suspect this very thing, called Halton Arp, who was swiftly removed from all telescope time on the basis of "That's a ridiculus suggestion". Maybe you will understand my question more with more context, he has many videos on yt, even a wiki page.
      2/. Dark matter is not an explanation its a placeholder label for something we do not have a clue about. What I am more after is "Has anyone actually considered the most simpliest layman solution to the problem, as opposed to inventing new invisible stuff and modifying something which works so well in the solarsytem making the matter more complex than it should be as us humans are liable to do". I believe the answer is "No science just assumes we have all the calculations correct".
      If you need to understand my stance more, here are more advanced questions which may help:
      From 1887 to 1925 (38 years) we have searched for an exotic form of matter called Luminiferious Aether. This idea was generally abandoned in the publics knowledge under the assumption it was not needed as we could not find any direct evidence of its existence.
      From 1930 to 2022 (92 years) we have searched for an exotic form of matter called Dark Matter. This idea is still being persued 92 years after its proposal without any direct evidence found ever.
      a/. Why did we abandon Aether so quickly yet are holding on to Dark Matter in comparison, when they carry the same layman descriptor of "A directly undetectable thing filling space"?

    There is an elephant in the room explanation for those abnormally high star rotation rates. We all heard the phrase "mass becomes infinite at the speed of light". This phenomenon is illustrated in a common relativity graph with velocity (from stationary to the speed of light) on the horizontal line and dilation (sometimes called gamma or y) on the vertical line. Mass that is dilated is smeared through spacetime relative to an outside observer. Even mass that exists at 75% light speed is partially dilated.
    Wherever you have an astronomical quantity of mass dilation will occur because high mass means high momentum.
    There is no place in the universe where mass is more concentrated than at the center of a galaxy. 99.8% of the mass in our solar system is in the sun. 99.9% of the mass in an atom is in the nucleus. If these norms are true for galaxies than we can infer that there is 100's of trillions of solar masses at the center of common spiral galaxies. There is no way to know through observation, there is far too much interference, dilation and gravitational lensing. If we attribute a radius to these numbers than we can calculate that relativistic velocities exist in these regions, the same way we could calculate the surface velocity of the sun if we doubled it's mass.
    The mass at the center of our own galaxy is dilated. In some sublime way that mass is all around us because as the graph shows we are still connected to it.
    It was recently discovered that low mass galaxies (like NGC 1052-DF2) have normal star rotation rates. This is what relativity would predict because there is an insufficient quantity of mass to achieve relativistic velocities. This is virtual proof that dilation is the governing phenomenon at galactic centers, there can be no other realistic explanation for this fact.
    A simple way to confirm this would be to calculate the star rotation rates of a large number of galaxies. This would show that all the high mass galaxies have star rotation rates that defy the known laws of physics and all the low mass galaxies (some galaxies can appear to be low mass but can have high mass at the center) would have predictable star rotation rates.

    Why can't the phenomena attributed to Dark Matter be explained by long-wavelength gravitational waves, where galaxies are standing wave vortices sweeping matter into spiraling crests, and the Bullet Cluster has a lensing wave peak separating the luminous halves?

    Hm, I'm not convinced that Dark Matter is the best "explanation" to this "lack" of matter that still causes gravity / bent spacetime...
    Isn't Dark Matter just the "mass we're missing" for our equations to make sense, by definition?
    I feel it unfair to give it that much credit as an actual "explanation", when it might just be exactly the "gap" in the understanding we have so far.

    It would seem the dark matter problems would be fixed with a tiny (on the order of gravity) anti normal matter force. This would also explain why we can’t detect it.

    Human and mammalian genome, made of DNA (nucleotides) wherein anywhere between 70-90 percent in genome is "junk" of unknown function but has subtle influence . Most accumulated due to viral integration etc. It "protects" coding or functional dna since mutations happen within these long stretches rather than more frequently in functional part.sometimes it also gains a function and affects genes in other ways. So maybe dark matter makes structure formation possible and protects them from insults in some way? And like it's genomic counterpart, is also made of the same stuff...yeah anologous. I still hate dark matter and energy though and would like another explanation

    • @pavel9652
      @pavel9652 Рік тому +2

      1) Do you have source of the claim? I have heard it in the past, but some 90% of junk code seems to be somewhat excessive. 2) How junk code protects from mutations since the amount of mutations should rise linearly with the length of the code? It might protect from certain types of mutations, though. I would have to think about it. 3) The dead code influences the evolution since parts can get activated. I agree on that one! 4) Dark matter help form structures like spiral galaxies because it has large mass or there is a lot of it, but it does not interact with EM fields, so doesn't heat up, etc.

      Pubmed has references to these claims. I used to work on this in late 1990s . No more. This claim is indeed disputed and there used to be an active discussion but I don't follow it any longer. But given that the genome is 5 billion letters and even if we assume 100000 genes( actual no is supposed to be much lower although proteins are many more) it doesn't seem sufficient to cover that length. And you're right. Some can get activated and influence the course of evolution too or have influence on phenotype.
