Complex Dark Matter

Ғылым және технология

After a century of study, scientists have come to the realization that the ordinary matter made of atoms is a minority in the universe. In order to explain observations, it appears that there exists a new and undiscovered kind of matter, called dark matter, that is five times more prevalent than ordinary matter. The evidence for this new matter’s existence is very strong, but scientists know only a little about its nature. In today’s video, Fermilab’s Dr. Don Lincoln talks about an exciting and unconventional idea, specifically that dark matter might have a very complex set of structures and interactions. While this idea is entirely speculative, it is an interesting hypothesis and one that scientists are investigating.

    For a long time I was a fan of modified gravity over dark matter. I like to understand gravity as a natural force of the cosmos wanting to be empty and attempting to push all matter out of it's way; Not exactly a force of matter wanting to pull other matter into it. This kind of generally explains both why "dark matter" holds galaxies together as well as why "dark energy" is pushing galaxies apart. I know there's been attempts at creating theories based on these principals; however when you figure out a formula for one galaxy, it doesn't quite fit with another. Recently I've been thinking; why not both? What if galaxies had variable amounts of wimps and other dark matter entities but not nearly as much as much as our modern understanding of gravity would predict. Dark charges are another interesting wrinkle; makes me think about other possible unknown variables. It will give me something to think about on my evening run. Thanks!

Every dark matter vortex is connected to every matter vortex. At their Inertial plane, connecting into a hyperboloid, between Space and Counterspace. I liked the last idea the best. A little of the other 2. Dark energy is magnetism/Birkeland currents. Magnetism gives Magnitude to the Universe. Birkeland currents holds everything together. Stars are created when Birkeland currents short across Space and Counterspace. Leaving a hyperboloid between Space and Counterspace. Monopoles in Stars in Space and Counterspace.

I have great faith in the fact that one day humans will learn to create a relative, localised, field of gravity, whilst being able to ignore any other gravities around it. Once we can do that, travel amongst the stars will be the norm, not a dream. We arent that far away.... In an infinite universe there are infinite possibilites..... Can we do it?

    Well, we might be able to mess with the Higgs field, but it won't work the way you want it to. The Higgs field only contributes to the mass of elementary particles, for composite objects most of the mass comes from the interactions holding them together. For instance, a proton is made of three quarks with a total mass of about 8 to 12 MeV, but the proton mass is 938 MeV. So, even if you completely removed all the mass from the Higgs field, you would still have about 99% of the mass left over. Also, i208khonsu is correct in pointing out that you would totally mess with atomic physics and chemistry.

    I applaud your use of the term "possible" in regards to dark energy an dark matter. Even though the evidence is mounting for their existence, we still don't have direct, confirmed identification of either. I am looking forward to the hi-fi lensing studies and continued efforts to detect elusive weakly interacting particles. It's much like identifying/quantifying the water vapor that the clouds form from before spectroscopy. I still think a large part of it is regular matter, much of which is behind event horizons. Gais recently discovered massive amounts of white dwarfs never seen before, and there are undoubtedly even more brown dwarfs and black holes that we will not be able to detect by any means, for centuries to come.

But the dark matter too must move and be impacted by light matter, yes ? So it is not enough to explain what form the dark matter can have, we must also show how it could have gotten that shape in the first place. Within those models, are we in a kind of equilibrium where dark matter and light matter patterns can more or less keep they shape they have (disk like galaxies etc..) or are the shapes of things unstable (in the scale of billions of years) ?

    As far as I know dark charge and whatnot doesn't really help explain anything, its just something interesting to think about. What it does do though, is that if its true then it might give us more ways to measure dark matter. For instance, I think I heard something a while ago about an idea where dark photons had a chance to convert into normal photons and vice versa, which predicts that you should see a little bit of light shining through walls and stuff. Usually this kind of thing isn't considered likely enough to get its own experiment, but they might try analyzing the data from other experiments looking for new kinds of signals.

    One observation I have is that visible matter exists entirely/mostly within the galaxy and is surrounded by dark matter.Therefore it is very likely that visible matter came from the surrounding dark matter. The idea is that dark matter changes when it enters warped space such as in a galaxy. To go on I'd say that way out there between galaxies matter has no weight and therefore electrons are not attracted to protons but once these particles enter warped space, the proton becomes 1000x heavier than the electron and the electron is forced to orbit the proton. This idea means that the strong nuclear force is really gravity at work on the very small. but this is all just wild speculation.

And for why we see outer stars of galaxy orbiting faster then it should be it is because time runs faster in less dense area of outer side of galaxy so that appears that they are moving faster relative to us . If it's wrong then why ???

    Ok, we seem to have two camps: One that says "Dark matter is stuff we dont have the ability to see" and Two: "Magical mystery stuff that doesnt interact with anything, in any way". At 8:00 the graph shows "strongly interacting dark matter" which negates theory of dark matter #2, which, of course, leaves theory #1: Stuff that we dont have the ability to see. In other words dark matter = stuff we dont have the ability to see, which of course means that its normal matter that strongly interacts. Hence the latest papers on the halo surrounding galaxies are much larger than previously believed. One paper says that the halo around the Milky Way galaxy may be as much as (or more than) 600,000 light years across, as apposed to the size of the Milky Way itself being 100k-110k light years across. There is no need for dark matter when you account for the nearly invisible halo and EM's.

Oumuamua was discovered only because astronomers are intensely studying the space between the stars, looking for anything there. We've even discovered a few rouge planets this way, just nothing approaching the numbers needed to add up to five times the mass of our galaxy. And he didn't say they've been ruled out to exist (they do exist, we've found them by doing exactly what you think astronomers aren't asking), just that there aren't even close to enough of them to explain dark matter. Give astronomers some credit here.

    My bet (pure speculation) for dark matter is supermassive black holes (quasar remnants). As black holes gain mass, they gain volume at a much higher rate. At some point, their density becomes less than that of air. This might cause them to stop interacting with other matter on a quantum level. Light, electrons, and other matter would pass right through them. They become large clouds of gravity.

    Flat Earth has no strong arguments of any sort and can be easily demonstrated false. It's a case completely different from String Theory. String Theory, or at least its specific forms like M-theory, do make predictions such as supersymmetry or extra dimensions, the real problem is empirically testing those predictions. But so was the case for many other theoretical predictions of older theories. I'm no fan anymore of String Theory but I won't accept it's just a theoretical rant, as every theory it does predict things we don't know yet about and that we may find about in the future if technology and ingenuity allow.

    Dr. Lincoln, Great Video! Most informative. I would like to offer you a simple suggestion for why there is no need for dark matter in the rotation of other galaxies. Galaxies are rotating as they form because their parent entity was rotating. This rotation is not kinetic from the galaxy's frame of reference. No two galaxies have a frame of reference in common, so our observations of other galaxies need to be adjusted accordingly. If we observe a galaxy with a redshift greater than 1.4, our difference in speed is more than the speed of light, we cannot possibly have frames of reference in common, what makes any other galaxy any different than this normal? Thanks.

    When was that? It's always been the case, always, that unexpected results mean one of two things: 1) Your theory is wrong, or 2) You discovered something new. If we took your approach we would have never discovered anything new in history. If you want to come up with a new theory, be my guest. Lots of people a lot smarter then you or I have tried and failed, so for now we go with the dark matter theory. But if you do come up with a new theory of gravity, remember it must both explain current observations AND not conflict with other areas of physics. Coming up with a new theory to explain dark matter is easy. Doing so without breaking all the rest of physics is extremely hard. Good luck.

    the dark matter/energy sphere is the confluence sphere for the energy of the local system. The disc comes from matter focusing near the center plane on axis. Why energy distributes into spheres, I have yet to imagine. But dark matter really seems to be like the ocean, and ordinary matter is the land created by that ocean. An ocean which spewed forth the elements, nutrients, and energy required for these islands to host higher metabolism life forms of greater detail and volition.

    The dark particle you seek is very likely the neutrino, the dark energy would be the Higgs field itself, or, rather, it’s otherwise undetectable particle constituent, and the dark photon is something you definitely wouldn’t see, as it wouldn’t have a wave form, it instead would spin around heavier mass carrying particles and produce a fluctuating ‘glow’ of sorts via electron interaction And you’d most likely find that dark photon in a black hole, due to the effects of its gravitational force compressing the photon’s structure and it’s concentrated electro magnetic field warping the photon’s wave form into a circular flow I’m probably crazy, I know, but look into that if you run out of doors to check, physics likes inventing new particles it can’t locate to answer and explain new problems when it has enough lying around, with little understood properties, that could very well answer these questions, perhaps we just need to check what we already have available first?

    That would be dark energy, not dark matter. But you'd probably need a huge vacuum space to generate such dark energy, so it seems impractical (would not fit inside any spaceship or the spaceship would not be able to be made of matter: too "energetically dense" for dark energy to happen). Also dark matter does not seem to interact in all the electronuclear spectrum, what seems quite impractical for any use, unless you power your ship by some, seemingly impossible, form of "gravity polarization" which I cannot even fathom (and in which case a rock would also probably do the job using less space).
