I love it so much when someone can explain advanced science clearly to me. I am not a scientist and I don't naturally think like one, so exciting insights into the nature of our lives wouldn't be available to me if there weren't people on this Earth who have the ability--a gift--to make what our species is learning clear and comprehensible in layman's terms. I'm just so thankful for that. Thank you articulate scientists for not keeping us in the dark! :)
This is the problem with education - we teach children to 'know the answers' but at the highest level of the scientific art we accept 'I'm still searching' - perhaps she's earned the right by way of a PhD to say 'not sure yet' but isn't that something? We punish kids for not knowing until they earn the right to not know by searching for something that's difficult to explain
yes but it’s vital that, if physicists don’t have any solidified idea based off of hard evidence, that they clarify that their ideas are mere hypotheses and should be taken into account, but at most with a grain of salt
@@ramzichouk4080 sorry but it wasn't "god in the equations" that provides our understanding of the universe, that enables religion peddlers a platform to preach.
Thank you Ms. Risa Wechsler for giving such an interesting talk about such a fascinating subject. It must be really amazing to work in this area of astronomy.
Hint: your are seeing the universe in one perspective or in one visible dimension spectrum. Dark matter sits just under the surface of this visible dimension that has enough influence. It is Like water in a bathtub and gravity is like a hole in the bathtub / sink, you dont see the water but whats in the water .. Think of a triangle recycle symbol.
@@BB-zq6hy its simple. Two ancient universes fell in love "Collided" and the spark gave birth to our adorable baby universe, which overtime grew and became more complex, . The reason the Universe is getting faster is because its going through puberty..

Her shrill voice cuts through your consciousness like a surgeon's scalpel without the administration of even the slightest anesthetic. So, what can she do? How can we preserve her without being hit with a serious case of trinnitus after her lecture?

The weirdest thing about dark matter is NOT that is doesn't react with normal baryonic matter BUT the fact that it doesn't react with itself. We could expect that dark matter could be submitted to the interaction of the forces that created it but it seems that is not the case. Think about that: it would certainly coalesce in some dark matter [?] stars if it could, and sometimes those gravitational pits would mix with stars' gravitational pits, thus adding to the gravity of the system then boosting the pressure and nuclear activity of those stars. We would see many low mass stars shining like bigger ones. We would have supernovae much more often since smaller stars could achieve iron fusion. But we don't see any of it. No hint of it at all. So even if you reach a critical mass of dark matter that would normally collapse in a star, the collapse is never achieved since dark matter would just continue it's way just right through itself and never pile up. So dark matter is just wandering around like a thin gas. But! And it's a big but: I don't think dark matter can escape a black hole since it''s sensitive to gravity (time-space curvature). So, a big part of the mass of the oldest black holes must have been made dark matter. That actually might explain the existence of supermassive black holes since those seem to have been formed pretty soon after the Big Bang when dark matter's density was way higher than it is today. You see, there is an upper limit at the speed of what a black hole can gobble up. Normal matter when it get heated up in the accretion disk radiates so much energy that it blows part of the gas falling and slow down the amount of matter reaching the black hole. But with dark matter, that wouldn't happen. (Ok, right, dark matter may radiate some form of energy that can only interacts with other dark matter particles, but I doubt that). So, early supermassive black holes may have been mainly filled up with dark matter.
When i was first introduced to biology in high school i was intrigued. What made it work? How do things function? Im so sorry i was educated by people who had a reply of nobody knows instead of well amino acids combine under the right conditions and create single cell life etc. it turned me off to science for so long because i was like welp ill never know
"We're even trying to make dark matter here on earth"....Please don't. I wish scientists would find other ways to get information other than experimenting with things we're still utterly clueless about.
Dark matter is what our universe expands into. The dark matter forces the universe matter through a smaller space which speeds up our expansion and produces dark energy from the friction of dark matter on the universes matter.
Thank you very much for enabling and then sharing a TED talk on this topic! In my case, and maybe many other cases, videos like this give us guidances to topics/disciplines we really would love to engage more with intellectually/socially, but don't have the opportunities in offline life. Thank you for helping keep our hope and sparks alive. :')
They used to like Carl Sagan for example. The problem is he died of old age and new "Christian Scientists" were born to take his place. In fact the whole BIG BANG actually started with a Catholic Priest named George Lemaitre
Probably because they don't understand what a conjecture is. Unfortunately, there are a lot of scientists who have a dogmatic view of science. You've to able to understand when this is the case.
There are conjectures and conjectures, there are facts and also lot of things in between. If you do the maths, some ideas are really strong, Quantum Mechanics for exemples. So strong your phone works thanks to it, pcs works thanks to it and it helps to explain so many things. And still we know for a fact it could be false even tought it works, now, really well. So is Quantum Mechanics a conjectures? No, but it could be, maybe it is, but not so much, isn't it?
Some entity out there in TED land, who has the resources to do so, please do my gravity test to see if my Theory Of Everything is correct, so that species from this Earth might survive beyond this Earth: (Reusable code from my files): Here is the test for the 'gravity' portion of my TOE idea. I do not have the necessary resources to do the test but maybe you or someone else reading this does, will do the test, then tell the world what is found out either way. a. Imagine a 12 hour clock. b. Put a magnetic field across from the 3 to 9 o'clock positions. c. Put an electric field across from the 6 to 12 o'clock positions. (The magnetic field and electric field would be 90 degrees to each other and should be polarized so as to complement each other.) d. Shoot a high powered laser through the center of the clock at 90 degrees to the em fields. e. Do this with the em fields on and off. (The em fields could be varied in size, strength, density and depth. The intent would be to energy frequency match the laser and em fields for optimal results.) f. Look for any gravitational / anti-gravitational effects. (Including the utilization of ferro cells so as to be able to actually see the energy field movements.) (And note: if done right, it's possible a mini gravitational black hole might form. Be ready for it.) (An alternative to the above would be to shoot 3 high powered lasers, or a single high powered laser split into 3 beams, each adjustable to achieve the above set up, all focused upon a single point in space.) 'If' effects are noted, 'then' further research could be done. 'If' effects are not noted, 'then' my latest TOE idea is wrong. But still, we would know what 'gravity' was not, which is still something in the scientific world. Science still wins either way and moves forward. Revised TOE: 3/25/2017a. My Current TOE: THE SETUP: 1. Modern science currently recognizes four forces of nature: The strong nuclear force, the weak nuclear force, gravity, and electromagnetism. 2. In school we are taught that with magnetism, opposite polarities attract and like polarities repel. But inside the arc of a large horseshoe magnet it's the other way around, like polarities attract and opposite polarities repel. (I have proved this to myself with magnets and anybody with a large horseshoe magnet and two smaller bar magnets can easily prove this to yourself too. It occurs at the outer end of the inner arc of the horseshoe magnet.). 3. Charged particles have an associated magnetic field with them. 4. Protons and electrons are charged particles and have their associated magnetic fields with them. 5. Photons also have both an electric and a magnetic component to them. FOUR FORCES OF NATURE DOWN INTO TWO: 6. When an electron is in close proximity to the nucleus, it would basically generate a 360 degree spherical magnetic field. 7. Like charged protons would stick together inside of this magnetic field, while simultaneously repelling opposite charged electrons inside this magnetic field, while simultaneously attracting the opposite charged electrons across the inner portion of the electron's moving magnetic field. 8. There are probably no such thing as "gluons" in actual reality. 9. The strong nuclear force and the weak nuclear force are probably derivatives of the electro-magnetic field interactions between electrons and protons. 10. The nucleus is probably an electro-magnetic field boundary. 11. Quarks also supposedly have a charge to them and then would also most likely have electro-magnetic fields associated with them, possibly a different arrangement for each of the six different type of quarks. 12. The interactions between the quarks EM forces are how and why protons and neutrons formulate as well as how and why protons and neutrons stay inside of the nucleus and do not just pass through as neutrinos do. THE GEM FORCE INTERACTIONS AND QUANTA: 13. Personally, I currently believe that the directional force in photons is "gravity". It's the force that makes the sine wave of EM energy go from a wide (maximum extension) to a point (minimum extension) of a moving photon and acts 90 degrees to the EM forces which act 90 degrees to each other. When the EM gets to maximum extension, "gravity" flips and EM goes to minimum, then "gravity" flips and goes back to maximum, etc, etc. A stationary photon would pulse from it's maximum extension to a point possibly even too small to detect, then back to maximum, etc, etc. 14. I also believe that a pulsating, swirling singularity (which is basically a pulsating, swirling 'gem' photon) is the energy unit in this universe. 15. When these pulsating, swirling energy units interact with other energy units, they tangle together and can interlock at times. Various shapes (strings, spheres, whatever) might be formed, which then create sub-atomic material, atoms, molecules, and everything in existence in this universe. 16. When the energy units unite and interlock together they would tend to stabilize and vibrate. 17. I believe there is probably a Photonic Theory Of The Atomic Structure. 18. Everything is basically "light" (photons) in a universe entirely filled with "light" (photons). THE MAGNETIC FORCE SPECIFICALLY: 19. When the electron with it's associated magnetic field goes around the proton with it's associated magnetic field, internal and external energy oscillations are set up. 20. When more than one atom is involved, and these energy frequencies align, they add together, specifically the magnetic field frequency. 21. I currently believe that this is where a line of flux originates from, aligned magnetic field frequencies. NOTES: 22. The Earth can be looked at as being a massive singular interacting photon with it's magnetic field, electrical surface field, and gravity, all three photonic forces all being 90 degrees from each other. 23. The flat spiral galaxy can be looked at as being a massive singular interacting photon with it's magnetic fields on each side of the plane of matter, the electrical field along the plane of matter, and gravity being directed towards the galactic center's black hole where the gravitational forces would meet, all three photonic forces all being 90 degrees from each other. 24. As below in the singularity, as above in the galaxy and probably universe as well. 25. I believe there are only two forces of nature, Gravity and EM, (GEM). Due to the stability of the GEM with the energy unit, this is also why the forces of nature haven't evolved by now. Of which with the current theory of understanding, how come the forces of nature haven't evolved by now since the original conditions acting upon the singularity aren't acting upon them like they originally were, billions of years have supposedly elapsed, in a universe that continues to expand and cool, with energy that could not be created nor destroyed would be getting less and less dense? My theory would seem to make more sense if in fact it is really true. I really wonder if it is in fact really true. 26. And the universe would be expanding due to these pulsating and interacting energy units and would also allow galaxies to collide, of which, how could galaxies ever collide if they are all speeding away from each other like is currently taught? DISCLAIMER: 27. As I as well as all of humanity truly do not know what we do not know, the above certainly could be wrong. It would have to be proved or disproved to know for more certainty.
You would like the magnet research of Mr. Ward, the Texan electrician who shows how to make an energy feedback loop with a drill, an electric generator and an osoloscope. Once you power up the drill motor into the generator and through the scope, you can observe the start up energy, and the generator energy combined. When you disconnect the start up source, the generator powers the drill, and has extra electricity available. He makes his experiments public and coined the phrase "Ward Force" to explain the energy where positive and negative poles meet.
@@loraxdavewalters2696 There are also videos here on RUclips that utilize magnets and coils that interact with each other to generate usable electricity without any 'normal' power source. In addition, one could also bury large metal plates in the ground at a certain orientation to the flow of energy going through the surface of the Earth and generate electricity that way too. (Earth batteries). The DC electricity generated could be utilized to split water into hydrogen and oxygen, of which could be stored and later recombined to get the electricity back with a by-product of basically pure water, and the world needs more pure water too.

What if dark matter isn't matter at all, but the effects of gravity from another parallel universe with slightly different laws of physics leaking into our universe?
So basically we still don't know what dark matter actually is, or how to detect it, or if it's even correct to attribute the theorised missing matter in the universe to so called "dark matter". It's simply a convenient phrase - a stand in - for a concept we have no understanding of. The release of this video gave me some hope that they'd made some more progress towards understanding what dark matter since the in-depth BBC documentary I watched a few years ago. I guess not.
I just wanna be pretty straight forward and ask a question that On what basis and observation do you calculate the percentage of dark matter,dark energy and matter??
1) Ratio of mass of Dark Matter vs. Visible matter: local measurement of gravitational pull and kinematics of stars in galaxies, and galaxies in the clusters. In more detail, we measure what we see (gas, dust, and stars in galaxies and between the galaxies), and their kinematics. Knowing how gravity between those objects would result in kinematics (Galileo, Kepler, Newton) that we do NOT see in real galaxies. We see that galaxies (stars within) are rotating as there is more mass than what we see. Also, intracluster gas and the galaxies in clusters move as there is some additional mass somewhere around. We proposed many hardly visual objects (heavy particles, Back Holes, brown dwarf, invisible gas, ...), but by deduction and better observations, we eliminated those candidates. 2) Ratio between Matter (Dark+visible) and Dark energy: assumptions about the universe, and how it expands. We measure how fast the universe expands, which depends on the ratio between gravitational energy (source in dark+visible matter) and some energy causing expansion. Also, different ratio between Dark energy and gravitational energy would end up with different slopes of densities of matter throughout the space (= how concentrated the density of matter is), and different look of the cosmic microwave background (CMB, CMBR).
An educated guess: Orbital period is related to mass, so by observing how fast stellar objects rotate in a galaxy as a function of distance from its center, you may infer approximately how much mass is involved.
Also: gravitational lensing. Gravity bends light. So by measuring how strongly light bends around a gallaxy, its mass can be inferred. The lensing can be observed by comparing how the apparent positions of more distant objects are distorted as a massive object passes in front of them.
Feels like science took a wrong turn somewhere along the way when normal matter is considered to make up less than 5% of our universe, the rest is something too dark to see, detect or comprehend.
Thank you for sharing this fascinating information about Dark Matter. So inspired by the image of Milky Way, such a beautiful view of somewhere I had no idea about.
I think, dark matter is exist in higher dimensions. We are only able to observing the consequences, in lower dimension. If we come to know how dimensions relate to each other, is there any mechanism exist in higher dimension, then may be mistrey of dark matter gets solved...
I hate to say this... But this talk sounds like we heard it a thousand times before and there's never anything new. I feel like I watched the same talk over 10 years ago.
What is astonishing me is the fact that she never says “ we think that... “ . All claims of modern cosmologists seem to be based upon solid evidence, but in my opinion this is far from being the truth.
Amedeo Filippi - agreed. The dark secret of cosmology is that it’s essentially a card house built on so many shaky axioms that it borders on religion. Time to divide science into that which can be called proven knowledge with a sober face, and that which is fascinating speculation, but forever beyond proof. Its reasonable to assume that the notion of dark matter is more related to the fact that we really don’t understand what causes gravity to happen, than to some kind of matter, whose essential property is that it is unobservable
@@BlueGTR100 Our understanding of our universe, its based on observations. which provide the technology that enables dimwits like you to comment on the internet
Simplest explanation of dark matter: The stuff we can't see or touch or measure or find has to be there because if its not, none of our basic math and physics laws work when we try to measure really big things.
Here's an idea. The universe, and everything in it is not just expanding, it's contracting and expanding at the same rate of time. So nothing is changes. But as we know planets and stars are moving away from each other then the question raises, how come? And the answer to that is,,,, loss of energy. No process is 100% efficient... it will lose some of the energy that was applied. And that lost energy causes the elastic affect on the distance
I think we forget something else. If there is dark matter we should also see some weird movements of galaxys, stars, planets... . that experience gravity from dark matter. Instead the movement is 100 procent of the matter we see only its stronger then we calculted. I mean i thing we forget something else and sorry for my english.
@youwhatnow haha, you are so polite! I mean, she is really knowledgeable, so confident, and she presents really well....but the pitch, the high pitch OMG!!
What if Dark Matter/energy is where two parallel universes bounce into each other and the energy in one leaks into the other? Parallel universes may not sit next to one another all well behaved and orderly-like. What if parallel universes move around the same way particles do here in our universe? That they even bounce against one another sharing internal forces for just in instant. If this map experiences changes and restructuring, it could be the result of outside influences. The current map could almost be considered like the pattern a cars windshield gets from seperate drops running into the glass and spreading around making pathways towards each other.
Models that don't include dark matter do not reflect out current universe. For example, when she was talking about the need for clumps of matter to form, models that don't include dark matter are unable to explain the seemingly accelerated attraction and convergence of matter. We know some sort of 'force' must exist and that visible matter does not account for all the matter we detect; dark matter fits the description quite well.
@@sivansharma5027 My model is simple but true: atoms ENTANGLE cross section from north to south or viceverse by electromagnetism keeping matter in groups togather but still all kind of matter are all jointed one to another electromagneticly speaking by overslapping one to another so the system is better united, now see that CMB makes a centripetal force to matter helping to even make a much strongger unification, you may see that even the stronggests light of all gets refracted by the electromagnetism that all systems have, if you have notice if you are an astrophysics follower that many pictures from the cosmos show a disc at the meadle that is where practicly the planets float, the disc is done by the north side and the south side so all this factors dont let matter to fly out galaxies or any other system, is not hard to see how all this factors keep matter were it belongs, see the video THE FLOWER OF LIFE OR DNA DECODED for better descriptions that you get seen colors cause relativistics not even see in black and white cause they are pairs.
Although we understand how gravity effects mass, we do not completely understand yet how mass and space interact to produce gravity because we do not yet understand what space is made of...until then, I think the chase for elusive matter may be a wild goose chase.
As much as people slam the whole 'dark matter' idea, you have to respect the scientists for working incredibly hard, some possibly for their whole career, dedicating their time in the knowledge that it may not even turn out to be the right theory. Science is a long-term pursuit of discovery and I always credit those who try to further our knowledge rather than sit around and dismiss every theory going as silly, because you never know what may turn out to be true!
Daniel The problem is our tax dollars are being wasted on this nonsense. If you want to look for something that doesn't exist, then knock yourself out, but do it on your own dime.

She says dark matter could be as large as the mass of 100 suns when talking about how big dark matter might be. But mass does not describe volume. Did she mean 100 solar volumes? Or that one particle is the mass of 100 suns?
@@zazugee Total mass? As in how much mass dark matter takes up overall in the observable universe is what you mean? That kind of makes no sense. If the total mass of dark matter was the equivalent 100 times that of our sun then there is no way that dark matter could take up the overwhelming majority of our universe. And we know it does take up that much. 100 suns is an infinitesimal fraction of how many stars there exists. There's 100 billion stars (100000000000) in our galaxy, and there is 100 billion galaxies in the observable universe. Mind boggolingly large numbers. For dark matter to make up 84% of the mass of the universe, as it does, it would need to have more mass than just 100 measly suns. Quite a gigormously enormously larger amount.
@@pseudonymousbeing987 i didnt catch this 100 sun reference but i think she was using it in a fraction as in like missing 100 sun mass in the solar system to give an idea of what we dont know
How can you take a physicist seriously who doesn't know how to pronounce Planck? We can't see it, we can't detect it, but we know it goes right through us?
Please define your variables. You seem to have a velocity as your final line. But don't say what it is that is moving. Is it the Galaxy? At what distance from the center? Do you have a link to a more clear explanation?
Subject: Alternative theory for dark matter IMAGE GRAVITY (SS):- Existing structure of galaxies are not stables without dark matter But a new force which is image gravity (named by me as “SS”) will be introduced by me. Explanation in brief :- Line of attraction (Gravity ) between two celestial objects is the vector sum of two components one in a straight line and other is in a curve. Curve component is only in plane normal to equator. The angle (named by me as Angle of Power, P) can be as high as 40- 50 Degree for bullet clusters or around 1 degree for stars on outer rings of galaxies. 1. Angle of Power (P) is proportional to distance (R), and Rotation of object. 2. Gravity field (normal component) + Gravity field (curve component) are equal to (G Mm /R 2) normal gravitational law for near objects only. 3. Gravity Field (normal component) is reduced with square of R but Gravity Field (Curve component) is reduced by R only as it is one dimension less than gravity. 4. Angle of Power (P) is called so because it provides extra energy and pull for the revolving object. 5. Image gravity (SS) will be created at the point of interaction of the curve component of both the objects. 6. A constant is required in the equation. 7. After solving this equation on available data of many galaxies we can actually find the correct value of G also ( up to 20 Decimal points ). 8. For a cluster of galaxies it can be taken analogues to a domain in a magnet. This theory is under evolution and critical comments are required.
Unlikely, we are a very limited species. With our natural grasp of only 3 dimensions. We cant even detect the majority of matter in the universe. We find out more, sure. But we wouldn’t “find out” as in solve this thing we called universe.
Damn I keep waiting for a vampire to come along and single me out for special consideration for immortality. Just so I can hang around for a few thousand years and find out all the cool things science is going to discover in the future. Gonna be so pissed off when I die.
If there is only matter and dark matter in universe then why do we say that there is vaccum in space due to which we can't hear sound in universe? How much vaccum is there(I mean density in universe)? I'm 10class student plz answer anyone 😊
Dark matter is really matter to our whole university, these visiable matter is just a cluster of dark matter, dark matter can be treated as the ash of enery.
Because someone has worked out that we need nearly six times more mass in the universe than we have (we have 15%, need another 85%). It might be dark matter, or something else, or the premise may be wrong...
Although I've already learned most facts from the speech, - Still was very interesting to listen, and I've loved how the speech was formed, and the sequence of the presentation - 👍🌟 - Thank You! - it was pleasure to listen - ✨✌️
Every spiritual and science text say the same thing, "there was nothing in the beginning just an energy source" and my friend you're a part of it. I guess, what we call soul or spirit or the life energy is a kind of dark energy.
I keep feeling like someone is going to discover dark matter is just the other entanglements in Hilbert space that we are separate from. Meaning in many-worlds, there exists all probable outcomes so we are dark matter to the other outcomes that are not entangled with our universe. ¯\_(ツ)_/¯
99.99 of matter in the universe is entangled one to another and if some is not it just follows the other cause is encapsulated by electromagnetism that later will be burned to produce energy as trees are for other trees.
Dark Matter: Possibility A: We can't find 90% of the universe. Possibility B: We have a completely wrong understanding of gravity. I wonder which one it could possibly be ...
One thing I don't understand; She and other scientists, often talk about Dark Matter going through us and other "normal" matter, without interacting in any way, hence the difficulties to detect it, but then go on to tell us, that dark matter was integral in forming stars and galaxies made of "normal" matter. How would dark matter affect the forming of stars and galaxies, or even just matter clumps if it doesn't interact with matter in any way?
Ok so what alarms me the most is the statement "what is it?...well we have no idea" and the following statement "We're even trying to make dark matter here on earth by smashing particles together"
My idea so I get to name it! Voyager 1 is now in interstellar time or "Mikey's Time." Think of it like Alvin and the chipmunks. "Vyger's" message is fine. It's just sped up now that it's outside our suns time bubble or "Terran Time." It would be faster still if "Vyger" sent a message from beyond the Milky Way's time bubble. (That name is still up for grabs.) Then there's Outside the Local Group time bubble, so on and so on until we get to the, "True Interstellar Time Standard." Now that "Vyger" is in interstellar space, it's also in the Milky Way's STANDARD, faster moving, interstellar time or "Mikey's Time." •Our sun's time bubble: "Terran Time" we know and have measured. •Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring. Wild guess I'd say time will increase in speed, now and until Vyger is outside the Ort cloud .007-.07% faster, maybe. Just for reference. •Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08% to a couple seconds faster, maybe. Used just for reference. •Outside any influence in the, "True Interstellar Time Standard," or...;-P Name NOT up for grabs BUT just begging to be measured. The rate/flow of time is fastest here so, surfing time here is choice. Though it's best to have your motor boat. ;-P A minute is a minute in all. It's the rate/flow I'm talking about. The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time." Pass it on, please and thank you.
Just like how Higgs Boson gives matter particles mass, what if dark matter actually gives particles the charges that they have? As someone who believes in interdisciplinary scientific studies, what if we compare the white matter and grey matter in our brain with the normal matter and dark matter in the universe? (I am saying so because when the presenter showed the clusters of galaxies just after the formation of the universe, it appeared to me like neuronal networks in the brain...)
What if dark matter or the matter we can't perceive. Exists on multiple planes of existence, such perceivable and non perceivable existence. And what if dark matter exists in nonlinear time. Which could explain why we can see its affects on things we can see and have knowledge of. But not it itself. A perplexed thing dark matter is.
Theres actually a theory that dark matter could be made by primordial black holes (black holes created a fraction of a section after the Big Bang) so that's a pretty good question. The primordial black hole theory also assumes that they contribute to super massive black holes.
Considering we only know less than 1% of what our universe is...i think its safe to say us monkeys dont even know if the big bang even happened, its just easier for monkeys to say "it went boom den all things wuz".
Look kid, I think you're missing just one of the basic qualities/properties of dark matter that it does NOT interact with itself so it couldn't form dark matter clumps by it's own
Dark matter is needed to explain many things in Astronomy, but the fact is that we are getting it wrong about the location of the dark matter. Dark matter exists in the parameters like there is an egg shell of dark matter. And what we call universe, is actually one bubble or pearl of a necklace of 18000 pearls with no string attaching them. Nature loves motion. Spinning, Rotation, and Revolving. This necklace of 18000 universes are in a circular motion within the thick shell of Dark Matter. Enveloped inside a shell of Dark Matter. Right balance has been achieved by AFFINITY (Gravity) of all these objects. Universes are not bumping into the wall of dark matter, as the circular necklace of 18000 universes have AFFINITY to pull together and sustain the shape of a necklace. All three motions of these 18000 pearls keep them on the right track of circular motion, not bumping into each other, not bumping into the wall of dard matter, and not pulled towards the centre of the Shell of the Dark Matter. The problem of the astronomers is solved. I know only that person can give the above account who has seen the shell and the pearls, or told be somebody who has seen it. Yes, someone has seen it for sure. At least the fact is better than the wild guesses by the scientists. By Mushtaq Qureshi - Manchester, UK. (Email: maqureshi@virginmedia.com)
Dark matter doesn't go through us. We go through the dark matter unaffected. Just like a fish moves deep in the water, unaffected and unaware of the fact that it is surrounded by water.
Spoiler: dark matter doesn't exist. In current quantum gravity theories at the edge of research, dark matter disappears. It is simply the error/discrepancy between a non-quantum description of gravity and a quantum description. The nature of gravity changes in very low gravity fields (which is the case in the outskirts of galaxies).
We don't know what 85% of our world is made of yet we claim to be the masters of it. Enlightenment should be about how we acknowledge our role and get in line like the rest of the universe. It's time to bend the knee to the Creator.

Remember when we couldn’t see infrared or UV light?, then technology advanced so that we could. I believe that if we could see further up and down the electromagnetic spectrum that we could see dark matter, but I’m not a scientist so I don’t know what we would have to do. Any feedback on this thought?
@wspaciao headimencional serna I'm referring more to the macro Electromagnetism, for example Our sun and some planets all combining their magnetic fields along with other Galaxies collective magnetic fields... From the the black hole in the center to all the stars, etc. There is this experiment some guy did who created 2 inverted bowl shaped metal to create a magnetic field and then threw magnetic balls in the center of them. It was interesting how each magnet spaced themselves evenly between the magnetic field created by the 2 bowls.
I love it so much when someone can explain advanced science clearly to me. I am not a scientist and I don't naturally think like one, so exciting insights into the nature of our lives wouldn't be available to me if there weren't people on this Earth who have the ability--a gift--to make what our species is learning clear and comprehensible in layman's terms.

The weirdest thing about dark matter is NOT that is doesn't react with normal baryonic matter BUT the fact that it doesn't react with itself.
We could expect that dark matter could be submitted to the interaction of the forces that created it but it seems that is not the case.
Think about that: it would certainly coalesce in some dark matter [?] stars if it could, and sometimes those gravitational pits would mix with stars' gravitational pits, thus adding to the gravity of the system then boosting the pressure and nuclear activity of those stars. We would see many low mass stars shining like bigger ones. We would have supernovae much more often since smaller stars could achieve iron fusion.
But we don't see any of it. No hint of it at all.
So even if you reach a critical mass of dark matter that would normally collapse in a star, the collapse is never achieved since dark matter would just continue it's way just right through itself and never pile up. So dark matter is just wandering around like a thin gas.
But! And it's a big but: I don't think dark matter can escape a black hole since it''s sensitive to gravity (time-space curvature). So, a big part of the mass of the oldest black holes must have been made dark matter.
That actually might explain the existence of supermassive black holes since those seem to have been formed pretty soon after the Big Bang when dark matter's density was way higher than it is today.
You see, there is an upper limit at the speed of what a black hole can gobble up. Normal matter when it get heated up in the accretion disk radiates so much energy that it blows part of the gas falling and slow down the amount of matter reaching the black hole. But with dark matter, that wouldn't happen. (Ok, right, dark matter may radiate some form of energy that can only interacts with other dark matter particles, but I doubt that). So, early supermassive black holes may have been mainly filled up with dark matter.

Probably because they don't understand what a conjecture is. Unfortunately, there are a lot of scientists who have a dogmatic view of science. You've to able to understand when this is the case.
There are conjectures and conjectures, there are facts and also lot of things in between. If you do the maths, some ideas are really strong, Quantum Mechanics for exemples.

Some entity out there in TED land, who has the resources to do so, please do my gravity test to see if my Theory Of Everything is correct, so that species from this Earth might survive beyond this Earth:
(Reusable code from my files):
Here is the test for the 'gravity' portion of my TOE idea. I do not have the necessary resources to do the test but maybe you or someone else reading this does, will do the test, then tell the world what is found out either way.
a. Imagine a 12 hour clock.
b. Put a magnetic field across from the 3 to 9 o'clock positions.
c. Put an electric field across from the 6 to 12 o'clock positions.
(The magnetic field and electric field would be 90 degrees to each other and should be polarized so as to complement each other.)
d. Shoot a high powered laser through the center of the clock at 90 degrees to the em fields.
e. Do this with the em fields on and off.
(The em fields could be varied in size, strength, density and depth. The intent would be to energy frequency match the laser and em fields for optimal results.)
f. Look for any gravitational / anti-gravitational effects.
(Including the utilization of ferro cells so as to be able to actually see the energy field movements.)
(And note: if done right, it's possible a mini gravitational black hole might form. Be ready for it.)
(An alternative to the above would be to shoot 3 high powered lasers, or a single high powered laser split into 3 beams, each adjustable to achieve the above set up, all focused upon a single point in space.)
'If' effects are noted, 'then' further research could be done.
'If' effects are not noted, 'then' my latest TOE idea is wrong. But still, we would know what 'gravity' was not, which is still something in the scientific world. Science still wins either way and moves forward.
Revised TOE: 3/25/2017a.
My Current TOE:
THE SETUP:
1. Modern science currently recognizes four forces of nature: The strong nuclear force, the weak nuclear force, gravity, and electromagnetism.
2. In school we are taught that with magnetism, opposite polarities attract and like polarities repel. But inside the arc of a large horseshoe magnet it's the other way around, like polarities attract and opposite polarities repel. (I have proved this to myself with magnets and anybody with a large horseshoe magnet and two smaller bar magnets can easily prove this to yourself too. It occurs at the outer end of the inner arc of the horseshoe magnet.).
3. Charged particles have an associated magnetic field with them.
4. Protons and electrons are charged particles and have their associated magnetic fields with them.
5. Photons also have both an electric and a magnetic component to them.
FOUR FORCES OF NATURE DOWN INTO TWO:
6. When an electron is in close proximity to the nucleus, it would basically generate a 360 degree spherical magnetic field.
7. Like charged protons would stick together inside of this magnetic field, while simultaneously repelling opposite charged electrons inside this magnetic field, while simultaneously attracting the opposite charged electrons across the inner portion of the electron's moving magnetic field.
8. There are probably no such thing as "gluons" in actual reality.
9. The strong nuclear force and the weak nuclear force are probably derivatives of the electro-magnetic field interactions between electrons and protons.
10. The nucleus is probably an electro-magnetic field boundary.
11. Quarks also supposedly have a charge to them and then would also most likely have electro-magnetic fields associated with them, possibly a different arrangement for each of the six different type of quarks.
12. The interactions between the quarks EM forces are how and why protons and neutrons formulate as well as how and why protons and neutrons stay inside of the nucleus and do not just pass through as neutrinos do.
THE GEM FORCE INTERACTIONS AND QUANTA:
13. Personally, I currently believe that the directional force in photons is "gravity". It's the force that makes the sine wave of EM energy go from a wide (maximum extension) to a point (minimum extension) of a moving photon and acts 90 degrees to the EM forces which act 90 degrees to each other. When the EM gets to maximum extension, "gravity" flips and EM goes to minimum, then "gravity" flips and goes back to maximum, etc, etc. A stationary photon would pulse from it's maximum extension to a point possibly even too small to detect, then back to maximum, etc, etc.
14. I also believe that a pulsating, swirling singularity (which is basically a pulsating, swirling 'gem' photon) is the energy unit in this universe.
15. When these pulsating, swirling energy units interact with other energy units, they tangle together and can interlock at times. Various shapes (strings, spheres, whatever) might be formed, which then create sub-atomic material, atoms, molecules, and everything in existence in this universe.
16. When the energy units unite and interlock together they would tend to stabilize and vibrate.
17. I believe there is probably a Photonic Theory Of The Atomic Structure.
18. Everything is basically "light" (photons) in a universe entirely filled with "light" (photons).
THE MAGNETIC FORCE SPECIFICALLY:
19. When the electron with it's associated magnetic field goes around the proton with it's associated magnetic field, internal and external energy oscillations are set up.
20. When more than one atom is involved, and these energy frequencies align, they add together, specifically the magnetic field frequency.
21. I currently believe that this is where a line of flux originates from, aligned magnetic field frequencies.
NOTES:
22. The Earth can be looked at as being a massive singular interacting photon with it's magnetic field, electrical surface field, and gravity, all three photonic forces all being 90 degrees from each other.
23. The flat spiral galaxy can be looked at as being a massive singular interacting photon with it's magnetic fields on each side of the plane of matter, the electrical field along the plane of matter, and gravity being directed towards the galactic center's black hole where the gravitational forces would meet, all three photonic forces all being 90 degrees from each other.
24. As below in the singularity, as above in the galaxy and probably universe as well.
25. I believe there are only two forces of nature, Gravity and EM, (GEM). Due to the stability of the GEM with the energy unit, this is also why the forces of nature haven't evolved by now. Of which with the current theory of understanding, how come the forces of nature haven't evolved by now since the original conditions acting upon the singularity aren't acting upon them like they originally were, billions of years have supposedly elapsed, in a universe that continues to expand and cool, with energy that could not be created nor destroyed would be getting less and less dense? My theory would seem to make more sense if in fact it is really true. I really wonder if it is in fact really true.
26. And the universe would be expanding due to these pulsating and interacting energy units and would also allow galaxies to collide, of which, how could galaxies ever collide if they are all speeding away from each other like is currently taught?
DISCLAIMER:
27. As I as well as all of humanity truly do not know what we do not know, the above certainly could be wrong. It would have to be proved or disproved to know for more certainty.
You would like the magnet research of Mr. Ward, the Texan electrician who shows how to make an energy feedback loop with a drill, an electric generator and an osoloscope. Once you power up the drill motor into the generator and through the scope, you can observe the start up energy, and the generator energy combined. When you disconnect the start up source, the generator powers the drill, and has extra electricity available. He makes his experiments public and coined the phrase "Ward Force" to explain the energy where positive and negative poles meet.
@@loraxdavewalters2696 There are also videos here on RUclips that utilize magnets and coils that interact with each other to generate usable electricity without any 'normal' power source.
In addition, one could also bury large metal plates in the ground at a certain orientation to the flow of energy going through the surface of the Earth and generate electricity that way too. (Earth batteries).
The DC electricity generated could be utilized to split water into hydrogen and oxygen, of which could be stored and later recombined to get the electricity back with a by-product of basically pure water, and the world needs more pure water too.

What if dark matter isn't matter at all, but the effects of gravity from another parallel universe with slightly different laws of physics leaking into our universe?
Gravity doesn't exist 😆
So basically we still don't know what dark matter actually is, or how to detect it, or if it's even correct to attribute the theorised missing matter in the universe to so called "dark matter". It's simply a convenient phrase - a stand in - for a concept we have no understanding of. The release of this video gave me some hope that they'd made some more progress towards understanding what dark matter since the in-depth BBC documentary I watched a few years ago. I guess not.
I just wanna be pretty straight forward and ask a question that On what basis and observation do you calculate the percentage of dark matter,dark energy and matter??
Gravity, my friend, what else?
1) Ratio of mass of Dark Matter vs. Visible matter: local measurement of gravitational pull and kinematics of stars in galaxies, and galaxies in the clusters. In more detail, we measure what we see (gas, dust, and stars in galaxies and between the galaxies), and their kinematics. Knowing how gravity between those objects would result in kinematics (Galileo, Kepler, Newton) that we do NOT see in real galaxies. We see that galaxies (stars within) are rotating as there is more mass than what we see. Also, intracluster gas and the galaxies in clusters move as there is some additional mass somewhere around. We proposed many hardly visual objects (heavy particles, Back Holes, brown dwarf, invisible gas, ...), but by deduction and better observations, we eliminated those candidates.
2) Ratio between Matter (Dark+visible) and Dark energy: assumptions about the universe, and how it expands. We measure how fast the universe expands, which depends on the ratio between gravitational energy (source in dark+visible matter) and some energy causing expansion. Also, different ratio between Dark energy and gravitational energy would end up with different slopes of densities of matter throughout the space (= how concentrated the density of matter is), and different look of the cosmic microwave background (CMB, CMBR).
An educated guess: Orbital period is related to mass, so by observing how fast stellar objects rotate in a galaxy as a function of distance from its center, you may infer approximately how much mass is involved.
@@renanbelli gravity is the glue that holds the lies together
Also: gravitational lensing. Gravity bends light. So by measuring how strongly light bends around a gallaxy, its mass can be inferred. The lensing can be observed by comparing how the apparent positions of more distant objects are distorted as a massive object passes in front of them.

The dark secret of cosmology is that it’s essentially a card house built on so many shaky axioms that it borders on religion.
Time to divide science into that which can be called proven knowledge with a sober face, and that which is fascinating speculation, but forever beyond proof.

Sexaquarks?
Wait is 20 years a long time to you?

The universe, and everything in it is not just expanding, it's contracting and expanding at the same rate of time. So nothing is changes. But as we know planets and stars are moving away from each other then the question raises, how come? And the answer to that is,,,, loss of energy. No process is 100% efficient... it will lose some of the energy that was applied. And that lost energy causes the elastic affect on the distance

What if Dark Matter/energy is where two parallel universes bounce into each other and the energy in one leaks into the other?
Parallel universes may not sit next to one another all well behaved and orderly-like. What if parallel universes move around the same way particles do here in our universe? That they even bounce against one another sharing internal forces for just in instant.
If this map experiences changes and restructuring, it could be the result of outside influences. The current map could almost be considered like the pattern a cars windshield gets from seperate drops running into the glass and spreading around making pathways towards each other.
I have this gut feeling that we are WAY wrong about the nature of the universe/reality.
Because society as a whole is arrogant
How can we model something we don’t know and say that we do know whether galaxies or universes would form or not? That is the question.
Models that don't include dark matter do not reflect out current universe. For example, when she was talking about the need for clumps of matter to form, models that don't include dark matter are unable to explain the seemingly accelerated attraction and convergence of matter.
We know some sort of 'force' must exist and that visible matter does not account for all the matter we detect; dark matter fits the description quite well.
@@sivansharma5027 My model is simple but true: atoms ENTANGLE cross section from north to south or viceverse by electromagnetism keeping matter in groups togather but still all kind of matter are all jointed one to another electromagneticly speaking by overslapping one to another so the system is better united, now see that CMB makes a centripetal force to matter helping to even make a much strongger unification, you may see that even the stronggests light of all gets refracted by the electromagnetism that all systems have, if you have notice if you are an astrophysics follower that many pictures from the cosmos show a disc at the meadle that is where practicly the planets float, the disc is done by the north side and the south side so all this factors dont let matter to fly out galaxies or any other system, is not hard to see how all this factors keep matter were it belongs, see the video THE FLOWER OF LIFE OR DNA DECODED for better descriptions that you get seen colors cause relativistics not even see in black and white cause they are pairs.
Although we understand how gravity effects mass, we do not completely understand yet how mass and space interact to produce gravity because we do not yet understand what space is made of...until then, I think the chase for elusive matter may be a wild goose chase.
How do we know that these forces are NOT from visible matter? Do we know that?
As much as people slam the whole 'dark matter' idea, you have to respect the scientists for working incredibly hard, some possibly for their whole career, dedicating their time in the knowledge that it may not even turn out to be the right theory. Science is a long-term pursuit of discovery and I always credit those who try to further our knowledge rather than sit around and dismiss every theory going as silly, because you never know what may turn out to be true!

I think this was very well done... congrats to her and her team
She says dark matter could be as large as the mass of 100 suns when talking about how big dark matter might be. But mass does not describe volume. Did she mean 100 solar volumes? Or that one particle is the mass of 100 suns?
total mass and not the mass of one single particle
@@zazugee
Total mass? As in how much mass dark matter takes up overall in the observable universe is what you mean? That kind of makes no sense. If the total mass of dark matter was the equivalent 100 times that of our sun then there is no way that dark matter could take up the overwhelming majority of our universe. And we know it does take up that much.
100 suns is an infinitesimal fraction of how many stars there exists. There's 100 billion stars (100000000000) in our galaxy, and there is 100 billion galaxies in the observable universe. Mind boggolingly large numbers.
For dark matter to make up 84% of the mass of the universe, as it does, it would need to have more mass than just 100 measly suns. Quite a gigormously enormously larger amount.
@@pseudonymousbeing987 i didnt catch this 100 sun reference
but i think she was using it in a fraction
as in like missing 100 sun mass in the solar system to give an idea of what we dont know
@@zazugee
No she definitely wasn't saying it like that.
@@pseudonymousbeing987 can you tell me what time she said that?
i cant rewatch the whole video now, i'm busy
How can you take a physicist seriously who doesn't know how to pronounce Planck? We can't see it, we can't detect it, but we know it goes right through us?
Dark Matter is Electromagnetic.
mcV=ezI
V=(e/m)(z/c)I=176Gx1.25u I
V=220km/s
This what's rotated the Galaxy fast, electricity like a Motor!
Please define your variables. You seem to have a velocity as your final line. But don't say what it is that is moving. Is it the Galaxy? At what distance from the center? Do you have a link to a more clear explanation?
Subject: Alternative theory for dark matter
IMAGE GRAVITY (SS):- Existing structure of galaxies are not stables without dark matter But a new force which is image gravity (named by me as “SS”) will be introduced by me.
Explanation in brief :- Line of attraction (Gravity ) between two
celestial objects is the vector sum of two components one in a straight line and other is in a curve. Curve component is only in plane normal to equator.
The angle (named by me as Angle of Power, P) can be as high as 40- 50 Degree for bullet clusters or around 1 degree for stars on outer rings of galaxies.
1. Angle of Power (P) is proportional to distance (R), and Rotation of object.
2. Gravity field (normal component) + Gravity field (curve component) are equal to (G Mm /R 2) normal gravitational law for near objects only.
3. Gravity Field (normal component) is reduced with square of R but Gravity Field (Curve component) is reduced by R only as it is one dimension less than gravity.
4. Angle of Power (P) is called so because it provides extra energy
and pull for the revolving object.
5. Image gravity (SS) will be created at the point of interaction of
the curve component of both the objects.
6. A constant is required in the equation.
7. After solving this equation on available data of many galaxies we
can actually find the correct value of G also ( up to 20 Decimal points ).
8. For a cluster of galaxies it can be taken analogues to a domain in a
magnet.
This theory is under evolution and critical comments are required.
got it, it's my soul.
I want to hear a physicist say “we WILL find out.” Scientific positive attitude isn’t foolish. Remain scientific but determined.
Like always, we'll find an answer.
-interstellar-
Unlikely, we are a very limited species. With our natural grasp of only 3 dimensions. We cant even detect the majority of matter in the universe. We find out more, sure. But we wouldn’t “find out” as in solve this thing we called universe.
The reason why Dark Matter particles have not been found, nor will ever be found, is that they don't actually exist.
Damn I keep waiting for a vampire to come along and single me out for special consideration for immortality. Just so I can hang around for a few thousand years and find out all the cool things science is going to discover in the future. Gonna be so pissed off when I die.
If there is only matter and dark matter in universe then why do we say that there is vaccum in space due to which we can't hear sound in universe?
How much vaccum is there(I mean density in universe)?
I'm 10class student plz answer anyone 😊
Watch the Channel "Space Time" instead
Hey im a fan of that channel too
The Big Bang needs a Big Banger.
Dark matter is really matter to our whole university, these visiable matter is just a cluster of dark matter, dark matter can be treated as the ash of enery.
wut
If you can't see 85% of the universe then how do you know the percentage rate?
Because someone has worked out that we need nearly six times more mass in the universe than we have (we have 15%, need another 85%). It might be dark matter, or something else, or the premise may be wrong...
Although I've already learned most facts from the speech, - Still was very interesting to listen, and I've loved how the speech was formed, and the sequence of the presentation - 👍🌟 - Thank You! - it was pleasure to listen - ✨✌️
Every spiritual and science text say the same thing, "there was nothing in the beginning just an energy source" and my friend you're a part of it.
I guess, what we call soul or spirit or the life energy is a kind of dark energy.
The dark matter is within us, and if channel it properly then we can be dark wizards.
wrong
I keep feeling like someone is going to discover dark matter is just the other entanglements in Hilbert space that we are separate from. Meaning in many-worlds, there exists all probable outcomes so we are dark matter to the other outcomes that are not entangled with our universe. ¯\_(ツ)_/¯
99.99 of matter in the universe is entangled one to another and if some is not it just follows the other cause is encapsulated by electromagnetism that later will be burned to produce energy as trees are for other trees.
Dark Matter:
Possibility A: We can't find 90% of the universe.
Possibility B: We have a completely wrong understanding of gravity.
I wonder which one it could possibly be ...
One thing I don't understand; She and other scientists, often talk about Dark Matter going through us and other "normal" matter, without interacting in any way, hence the difficulties to detect it, but then go on to tell us, that dark matter was integral in forming stars and galaxies made of "normal" matter. How would dark matter affect the forming of stars and galaxies, or even just matter clumps if it doesn't interact with matter in any way?
none sense, thats it.
Thank you for the amazing talk!
Ok so what alarms me the most is the statement "what is it?...well we have no idea" and the following statement "We're even trying to make dark matter here on earth by smashing particles together"
I bet she has a *lovely* singing voice.
Please do yourself a big favor and never go to Vegas!
Sam Sen hahahaha!!!!
If dark matter doesn't interacts with matter , then how does it influence matter ?
Because they are matter 🤣
Just joke
It does interact with matter. It just doesn't interact with LIGHT.
please don't make a galaxy bomb thank you :)
Easier to just ask Taco Bell to never offer coupons. 😈
Galaxy is already made up of billions of little bombs called stars. So.....
Read the xeelee sequence by Stephen Baxster
@@shinyheart3373 yeah so we should create more while we're at it?
My idea so I get to name it! Voyager 1 is now in interstellar time or "Mikey's Time." Think of it like Alvin and the chipmunks. "Vyger's" message is fine. It's just sped up now that it's outside our suns time bubble or "Terran Time." It would be faster still if "Vyger" sent a message from beyond the Milky Way's time bubble. (That name is still up for grabs.) Then there's Outside the Local Group time bubble, so on and so on until we get to the, "True Interstellar Time Standard." Now that "Vyger" is in interstellar space, it's also in the Milky Way's STANDARD, faster moving, interstellar time or "Mikey's Time."
•Our sun's time bubble: "Terran Time" we know and have measured.
•Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring. Wild guess I'd say time will increase in speed, now and until Vyger is outside the Ort cloud .007-.07% faster, maybe. Just for reference.
•Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08% to a couple seconds faster, maybe. Used just for reference.
•Outside any influence in the, "True Interstellar Time Standard," or...;-P Name NOT up for grabs BUT just begging to be measured. The rate/flow of time is fastest here so, surfing time here is choice. Though it's best to have your motor boat. ;-P
A minute is a minute in all. It's the rate/flow I'm talking about.
The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time."
Pass it on, please and thank you.
i'm guessing time is compressed until life observes = natures compression
can you imagine the family tension if this lady was married to a plumber or a guy who was stocking shelves at Walmart?
At least they accomplish sth every day
What to do when your gravity equations don't work? Throw in some dark matter and hope the public never calls you out on it.
I particularly liked the bit where she said that was when gravity 'turned on'.
I turned the movie 'Gravity' on
@@arindam1249 and it's about as scientifically accurate as anything this TED talk mentions.
Gravity is the glue to keep all their bullshit lies glued together
So everyone assumes space existed before this big bang. Love it...
Walter Issacson asked this same thing to Brain Greene and he answered that it is pointless to know what was there before the big bang.
Your comments help explain the Trump disaster .......
Truly
Just like how Higgs Boson gives matter particles mass, what if dark matter actually gives particles the charges that they have?
As someone who believes in interdisciplinary scientific studies, what if we compare the white matter and grey matter in our brain with the normal matter and dark matter in the universe? (I am saying so because when the presenter showed the clusters of galaxies just after the formation of the universe, it appeared to me like neuronal networks in the brain...)
Juicy topic! Can’t wait for more discoveries about dark matter. Thx for video
No one knows what dark matter is
There is no juice...just assumptions
Dark matter doesn't exist.
But i....
No juice, no discoveries. Just a very confused woman with the unearned confidence of a tenured professor.
What if dark matter or the matter we can't perceive. Exists on multiple planes of existence, such perceivable and non perceivable existence. And what if dark matter exists in nonlinear time. Which could explain why we can see its affects on things we can see and have knowledge of. But not it itself. A perplexed thing dark matter is.
Since dark matter has mass, why aren't there dark matter black holes?
Theres actually a theory that dark matter could be made by primordial black holes (black holes created a fraction of a section after the Big Bang) so that's a pretty good question. The primordial black hole theory also assumes that they contribute to super massive black holes.
Dark matter makes white holes
Considering we only know less than 1% of what our universe is...i think its safe to say us monkeys dont even know if the big bang even happened, its just easier for monkeys to say "it went boom den all things wuz".
Look kid, I think you're missing just one of the basic qualities/properties of dark matter that it does NOT interact with itself so it couldn't form dark matter clumps by it's own
Dark matter is needed to explain many things in Astronomy, but the fact is that we are getting it wrong about the location of the dark matter. Dark matter exists in the parameters like there is an egg shell of dark matter. And what we call universe, is actually one bubble or pearl of a necklace of 18000 pearls with no string attaching them. Nature loves motion. Spinning, Rotation, and Revolving. This necklace of 18000 universes are in a circular motion within the thick shell of Dark Matter. Enveloped inside a shell of Dark Matter. Right balance has been achieved by AFFINITY (Gravity) of all these objects. Universes are not bumping into the wall of dark matter, as the circular necklace of 18000 universes have AFFINITY to pull together and sustain the shape of a necklace. All three motions of these 18000 pearls keep them on the right track of circular motion, not bumping into each other, not bumping into the wall of dard matter, and not pulled towards the centre of the Shell of the Dark Matter. The problem of the astronomers is solved. I know only that person can give the above account who has seen the shell and the pearls, or told be somebody who has seen it. Yes, someone has seen it for sure. At least the fact is better than the wild guesses by the scientists.

Aether...
aether is the sea of lights filled with six colors light that make white at the center of the outer.
Dark matter doesn't go through us. We go through the dark matter unaffected.
Just like a fish moves deep in the water, unaffected and unaware of the fact that it is surrounded by water.
"The search for dark bullshit -- and what we`ve found so far." | Risa Wechsler
Very good
Spoiler: dark matter doesn't exist. In current quantum gravity theories at the edge of research, dark matter disappears. It is simply the error/discrepancy between a non-quantum description of gravity and a quantum description. The nature of gravity changes in very low gravity fields (which is the case in the outskirts of galaxies).
I DONT THINK SO.
I want her job that sounds so awesome
We don't know what 85% of our world is made of yet we claim to be the masters of it. Enlightenment should be about how we acknowledge our role and get in line like the rest of the universe. It's time to bend the knee to the Creator.
what if dark matter is just in some other dimension that we are unable to acess?
Well, if it were, it wouldn't affect our dimension at all - so we would have to find something instead
Thank you Ms. Risa for this amazing simple explanation 🙏
I know she try to talk loud and clear, but it's too pitchy and very uncomfortable
not for me. some people just need to complain, i guess
I tried playing it at 1/4 speed to see if I could bring down her pitch... Big mistake... Still painful and she sounds like a super drunk valley girl. Amplified the vocal fry to the point where suicide was contemplated.
I bet you can ward off mosquitoes with that voice...
the search goes on, because detection of dark-matter particles would exceed the excitement of anything that has emerged from particle physics in the past 20 years, including the discovery of the Higgs particle. The main purpose is to gain an understanding of the matter that comprises 85 percent of the universe.
I watch too many science videos.
And I still have no clue what reality is.
Eco Geek no you don't it's impossible to be too nerdy
Randy Hanna my bets on the simulation theory
Remember when we couldn’t see infrared or UV light?, then technology advanced so that we could. I believe that if we could see further up and down the electromagnetic spectrum that we could see dark matter, but I’m not a scientist so I don’t know what we would have to do. Any feedback on this thought?
What if electromagnetism collectively WAS the cause of what they call dark matter.
@@omrirotcod7035 in fact it is all is light made so even plastic must to be electromagnetic.
@wspaciao headimencional serna I'm referring more to the macro Electromagnetism, for example Our sun and some planets all combining their magnetic fields along with other Galaxies collective magnetic fields... From the the black hole in the center to all the stars, etc. There is this experiment some guy did who created 2 inverted bowl shaped metal to create a magnetic field and then threw magnetic balls in the center of them. It was interesting how each magnet spaced themselves evenly between the magnetic field created by the 2 bowls.
