Roughly 85 percent of mass in the universe is "dark matter" -- mysterious material that can't be directly observed but has an immense influence on the cosmos. What exactly is this strange stuff, and what does it have to do with our existence? Astrophysicist Risa Wechsler explores why dark matter may be the key to understanding how the universe formed -- and shares how physicists in labs around the world are coming up with creative ways to study it.

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

I always think it’s weird when physicists say “well we have no idea...but we have some good guesses”
Lol those guesses ARE your ideas
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

Great. Hope we will find soon .
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.
I got Dark Matter in Black Ops 3 by completing all gun challenges for each and every gun. Best looking skin in the game!

I feel like all scientist should say "maybe" before every thing they say!
That's the spirit of science. It's very, very hard to be sure of something
@@elismarlosch2434 So why do so many scientists present conjecture as fact?
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?
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 - ✨✌️
She has the most amazing job ever
the graphics are so good
@Dark Matter your welcome?....
Good job, thanks. I think DM is 'folded' in a dimension we can't see, but can measure the effects of,.. obviously.
As I replied to another comment:
I would suggest it's the 4th-infinitith at diminishing fractions of the 1st-3rd.
We can observe and measure 1-3, but 4+ is always there, beyond our perception.
Therefore, the mass we measure is 3d, but the mass gravity responds to is 4+.
Thus our gravitational constant has 4+d matter built in, because it was calculated from experiments in 3d. But astronomical observations only "see" 3d, and therefore don't "see" enough matter to make the gravity equations work. They aren't out there measuring up the weight of stars, they are thumbnailing from distant observations.
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 😆
Spiritual vs Material
Non Physical vs Physical
Nothing vs Thing
Conciousness vs Awareness
You can either Divide the Existence in Two Dimensions or You can Perceive them as One. If you can do the latter, then Life and Death will no longer be a mystery to you.

Thank you, It's a mission impossible cos don't know what to look for but only knew it's something there...
Bold statement to say that dark matter goes through us when we dont even know what dark mater is

Yes, but so scientific. She says 'probably'. What a joke.
@Andrew Brent In the universe there are infinite possibilities so good luck lol xD

No problem, man.

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...)
How could the mass/energy of the total universe be concentrated into some sort of quark gluon particle concentrate just after the big bang? And how could the universe cool down?
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.

Got a question. The only thing it seems we think dark matter can do is influence gravity. Ok it would go through material. Then wouldn't it accumulate in center of Earth or even another body and add to there gravity. If not then why?
I have just discovered the exact opposite of an ASMR voice. Let's call it Anti-ASMR.

She sounds like Bernadette from the big bang theory ...
this talk finally convinces me of existence of dark matter, or a quite solid hypothesis at least.
Love how she laughs every time she says “I have no idea”
Yeah, at the end she admits that everything she said is BS and just unproven theory for which no empirical evidence exists.
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 CZcams 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.

They've been looking for at least twenty years and have found nothing. I think they need a new idea
Sexaquarks?
Wait is 20 years a long time to you?
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
@@motro1301 Please tell me where you can buy those (a friend wants to know)
I liked only because your job is to create simulations of galaxies I think that's awesome. I've always said that if we could map the sky precisely enough, and correlate this data with all newspaper articles published ever since the invention of writing, we would have something like a time machine; or like Gideon in Flash, it could be a supercomputer capable of predicting future events . Not sure, but very probable
We will find it and I wanna be a part of it
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?
got it, it's my soul.
How do I make a universe model and play with it ?

Well because of our technology and physics the mistery of the dark matter (that I think maybe I would've not known for a long time or maybe not in this life as out of 100% things going around us we are only familiar with 15% of them rest 85% is dark matter to us like the mistery of dark matter itself but thanks to our technology and physics that helped this mistery to reach till me. And thank you TED for sharing such an interesting information with us ✨✨✨
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.
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.

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.
This is interesting stuff!! Thank you for your talk!
yes
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?
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?
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 😊
Mam jo aapne handwriting pyq book Li hai please pdf share kar do
i'm guessing time is compressed until life observes = natures compression
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
"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.
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.
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
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
I would like to suggest an experiment where a small blast is made inside a vacuumed room with 360 degree sensors to observe the effect of blast on all the sides of blast location and observing the differences in observation can give us clues about dark matter & dark energy
The quantum universe is quite exiting. I want a job in quantum physics so bad 👌🧐😎
Watch the Channel "Space Time" instead
Hey im a fan of that channel too
The dark matter is within us, and if channel it properly then we can be dark wizards.
wrong
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.
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.
Who came here for comments?✌
Yeah
Me
TED talk videos are a joke to people.
@@Utub3iS6aY
Nah, sometimes they are really good, not this one though...
I do, some times they feed my brain and I just let it go inside the show treaping out for ideas as I free fall inside comments.
Aether...
aether is the sea of lights filled with six colors light that make white at the center of the outer.
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.
right so how do we detect the influence dark matter has on other things and what influence are we measureing?
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
There is no dark matter. Anyone reading from 2050?
Yeah
Are you still alive? I'm typing with my legs
2060 now bro. Typing with my brain.
Hello punny humans.
Greetings from singularity era , the year 0002 AS.
Quick note: AS: After Singularity.
see the video THE FLOWER OF LIFE OR DNA DECODED in you tube is a dna picture found in you tube and I could say it takes out dark energy.
You time traveller?
Axions are dark matter. Though it's a virtual particle, it fits the bill.
So sound has a particle. Would gravity waves have a similar concept?
