This video omits an important part of the reasoning that leads towards dark matter. When observing that some stars move much too fast, there was two possible conclusions (aside from rejecting the observation, which is not possible now because the phenomenon has been observed a lot of times): ether there is "dark or invisible or hidden" mass in the universe, either the laws we use are false (false as in "correct here, incorrect there"). The second assumptions is logically valuable.
I didn't realize that the concept of Anti-worlds was even really taken seriously. That's pretty cool. What if we visited the Alpha Centauri system, found an Earth-like planet, found intelligent life there, and try to land. Well, Kaboom right? Is this seriously possible? It doesn't sound impossible to me based on what we seem to know about the Universe so far.
I did some reading recently re one of the experiments in the forthcoming mission. It is good to see being tested so soon. It was found, once someone had sat down and did the math, that even relatively small magnets should be able to shield spacecraft from deadly solar radiation. If so it would make Space travel safer, much more easily than had previously been thought to be the case.
@CerisePsyche I'm glad you brought that up because the one thing that has remained constant in the face of technological and scientific breakthroughs is poverty, hunger, disease, etc. So while some members of the scientific community are constantly looking for a bunch of stuff that will not help, people are still suffering. I never said anything about giving up on science. ALL I say is put the best minds on the toughest issues. You all need to calm the hell down too.
@immunetocommonsense Ah, okay, slight correction - since the idea of antimatter predicted an antiparticle for all particles then your statement might be true; it is however only a single prediction which lead to the discovery, so if you count the number of different kinds of particles (of which I'd count antiparticles as one) then it's incorrect.
@joncl1 I think RUclips introduced a new symbol to notify that there are NO comments in this video, thus you can't activate the bubble switch. That's my take on it, but i'm not sure.
@Hooya2 - I guess what I'm saying is couldn't gravity act like a lattice, the pull of the outer stars gaining momentum because of gravitation (like tidal friction), achieving a stable dispersion of energy. Gravity does act strange as seen in formation in the moon system of Saturn. (ie. Solar System formation) It is caused by resonance. (I think, I could be wrong??) I guess what I'm getting at is factors of distance that overlap.
More research into detection devices! Space needs fields of repulsion/attraction to keep things orderly. There are collisions when out of balance, but dark space contain fields. just because on our scale they might not seem like much, on a solar, or galactic scale, the sum of field particles, that may be nearly undetectable, I would think is huge on the whole. Also detection of energy, and how to decifer it are two seperate things. And that absolute zero barrier...
@apocalypseap actually I do volunteer in the city for after-school reading programs for kids who need it. So you could say I play my small part. thank you, though.
@heartlessvietboy Antimatter is merely an exotic word for some types of particles.Like the video alluded to, a particle with all the same exact properties as another particle except for charge is then the anti of that particle. The other is then the "normal" particle. What one is considered "normal"and what one anti, is conventional. Whatever one was discovered first is the "normal". In this case, the electron was discovered before the positron, so the electron is normal and the positron is not.
They are also counterparts; they come into being in pairs. Both come from light, when gamma ray photons collide. That's why scientists are scratching their heads wondering where the other type of matter went. Enigmas of the universe...
@Olemguy I'm not sure it would be that simple. If an anti-matter civilization exits, then it must be stable, therefore it should be protected by "something" in the universe that protects from this kind of bad encounter, so it would be difficult to send a matter bomb to an anti-matter planet. (Maybe this "something" is just great distance, maybe not)
@TehOwnerer999 From what I gather, dark matter should have an effect on anything that goes through it. It has mass, therefore must exert gravity. That's why the stars at the edge of galaxies are not being slowed by centrifugal properties. o.O?
does an anti matter mass within out universe mean there could be worlds withing what we can see, but that they are in a 4th dimention so we don't see them? Someone help me out on this?
I don't understand what it is about the speed of the outer stars that baffles everyone. It moves like a solid because it seems like there is no friction in the path of the stars, why couldn't they move this way. The bonds of gravity are like the bonds in a solid and the resistance is negligible. I don't know much about this stuff, so maybe someone could enlighten me.
@sammysf415 There are other ways of seeing (detecting) things then using your eyes. For starters, we have other senses like taste, touch, smell, and hearing which we use to detect things. In addition to these, we can construct devices that can detect emitted wavelengths of smaller or greater size then we are biologically capable of detecting (like x-rays, ultraviolet, or gamma rays), Then theres the idea of detecting the fact that something else detected something, which is indirect detection.
The narator says that a space shuttle is going to deliver this aparatus to the ISS, but the space shuttles have been taken out of service... What us correctN
Maybe there is little hidden mass. I find it unlikely that so much is hidden. May be it is the structure of the universe itself that causes these calculations to show so much hidden mass. It may be some characteristics of the universe that we not yet have discovered.
@cmxcmx I whole heartedly agree. Fertilizerspike is way too confident about his assertions. @Fertilizerspike 1)Prove that stars are charged enough to account for the attraction. 2) If stars are charged, and the plasma between them is of the opposite charge (I'm guessing negative?), then why would spiral galaxies behave the way they do? Your explanations hold no water. Your explanation doesn't explain why spiral galaxies spin more like a record than a liquid being stirred with egg beaters.
@Olemguy LOL! I think you'd be annihilated by the matter in their atmosphere before you hit ground...but man, oh man that would be one hell of a disastrous explosion! An entire spaceship instantly turned in to 100% energy....I can't even imagine.
@Poleschs In other words, you see the effect butt cannot find a cause. Hypothetically speaking, if no hard evidence for dark matter were eve rfound, how would you suggest cosmologists explain the gravitational discrepancies? Just interested if there are any other accepted mainstream explanations that don't rely on undetectable stuff.
I guess also to put what is in my brain in words would be the innermost areas have all the gravity from the center and the outer edges of the galaxy acting upon it where the outer only has gravity acting from inside it's orbit. I realize it is farther from the galactic core, but perhaps the gravity wells don't act in the fashion that was anticipated because of the scale. I need to learn more, I'm just speculating. I guess my thoughts fall along quantum gravity. No evidence for DM yet.
What if there is no missing mass, but the problem, is the way we are measuring it. Einstein said mass is not in space time, but are extensions of space time. So, what if the total mass of the universe, cannot be found, by measuring it in any single reference of time, in other words, at any given moment, there is a finite amount of mass, in that moment of time. So, to know the actual mass of the universe, we would need a way, to measure its mass over time. What I'm saying is, how do we know, that the missing mass of the universe, is not simply located, in different references of time? I mean what physics do we have, that says the total mass of the universe, must all exist, in a given reference of time? What I'm saying is, that if in a given measure of Time, if I measure the mass of the universe, how do we know, that that mass figure, is not specific to the time reference. If matter were spread out over time, then you could never measure it in a single reference of time, and get its total mass, since its spread out over time, to calculate the mass of the universe, would require formulating its mass spread out over time, and in all the universes time, that would give us the total mass. The missing mass, is lost in time, it's not lost in space. Some of its mass should exist in the past, some of it in the present, and some of it in the future. You would never be able to measure its total, from a single reference in time. I mean think of it like a pie, divided into slices. Each moment in time, would give you only a slice of the total mass of the universe. Any observation we make in time, would only reflect that slice, which you could never measure the total mass of the universe, by measuring just a slice, but you would have to find a way, to add up all of the slices.
@Blindianboy Stopping scientific research would be a huge mistake. Science benefits humanity by increasing our understanding of the universe and using it to our advantage. And that scientific research could very well benefit the people stricken by poverty, hunger and disease one day. Science is not the enemy here. Direct your passion towards things that really don't deserve as much money as they are getting. Like wars and religion to name a few. Compared to war, science gets almost nothing.
@immunetocommonsense Well... not really... most particles were never anticipated to exist, then found and after quite a while explained theoretically (sorta... for some of them)
Fascinating stuff... Maybe (and before you all jump on me - lol - this is a purely personal theory), all this 'hidden' matter is parallel universes? Or other 'physical' dimensions we're not able to comprehend except to conceptualise mathematically... Just thinking out loud (well, in text) - lol
@TomatoBreadOrgasm Let the world know that you think dark matter will stop poverty and hunger. Let the greatest minds on the planet keep looking for the infinite nothing. Well said, sir.
@D34dFilms So in short, science knows what they know, and knows what they don't know; in contrast with pseudo-science that doesn't know that (and what) it doesn't know.
Could it be that dark matter doesn't exist? Is it possible the mechanism that holds the universe together is not really gravity but electromagnetism? Using electromagnetism as the dominant force sure does solve much of the deficiencies in the standard cosmology model. It eliminates the need for dark matter.
@destronia123 scientist probably "invented" dark matter to explain stuff they don't understand as they "invented" Luminiferous aether to explain the propagation of light in the universe. Many times in the history of Physics some materials wre "invented" to explain something So I guess we just have to wait them to dicover the explanation
Atleast we can dismiss our theories, unlike religions. And we can PROVE that the discoveries and theories (some of them, counting out those we cannot prove and have dismissed like the aether) we have made are true!
@sensur1 lol, that is so true, I have tried arguing with him about stuff but essentially he never gives proof for anything. But, with help from a co-worker we figured out his sources. It called the Electric Universe Theory, or Plasma Cosmology, in this all his arguments are consistent, though absurd and conjectured theory.
@TomatoBreadOrgasm don't get upset because the priorities of your favorite people are fucked up. or maybe more people should get upset so we can fix the problems here instead of investigating some shit that more than likely will benefit no one.
Thank you BestOfScience and ESA!

Having to resort to a Dark matter hypothesis makes me think there is something very wrong with current cosmological models...

Old news, but thumbs up for promoting science.
Thanks for putting this out here!

3:56 What are those stats? I can't read them entirely because they got cut off. Does anyone know?
@joncl1 I think RUclips introduced a new symbol to notify that there are NO comments in this video, thus you can't activate the bubble switch. That's my take on it, but i'm not sure.
The universe is such a strange place, but every human is worried and stressed out about shit that dosn't matter.
my species is driving me crazy.

@D34dFilms But the more you know the more you discover which makes it even weirder...
Can normal matter interact with dark matter? E.g. could a ball of normal matter go straight through a thick wall of dark matter?
@Olemguy I'm not sure it would be that simple. If an anti-matter civilization exits, then it must be stable, therefore it should be protected by "something" in the universe that protects from this kind of bad encounter, so it would be difficult to send a matter bomb to an anti-matter planet.

What's with the cropping?
what are they gonna do with it when they find it? and how will it benefit me?
@TehOwnerer999 From what I gather, dark matter should have an effect on anything that goes through it. It has mass, therefore must exert gravity. That's why the stars at the edge of galaxies are not being slowed by centrifugal properties. o.O?
great information
wuts the exclamation point and message bubble thing by the vid. resolution???
does an anti matter mass within out universe mean there could be worlds withing what we can see, but that they are in a 4th dimention so we don't see them? Someone help me out on this?
This is super interesting & confusing to comprehend.
Thank you
Great video!
could particles keep getting smaller and smaller, down to infinity?
It's so cool that we know so little :) Exploration ftw!
Can anyone recommend a good book on this topic?
I don't understand what it is about the speed of the outer stars that baffles everyone.

If 95% of the known universe is stuff we can barely detect. Imagine how much other 'stuff' could be out there that we cannot detect at all !
This is a great video
The narator says that a space shuttle is going to deliver this aparatus to the ISS, but the space shuttles have been taken out of service...
What us correctN
@MpowerdAPE Congratulations, Mcgyver!
Awesome! That's all I can say. I can't wait till we find out what dark matter is exactly
those scientists are my superstars
Whoo Dirac, FSU represent!
Maybe there is little hidden mass. I find it unlikely that so much is hidden. May be it is the structure of the universe itself that causes these calculations to show so much hidden mass. It may be some characteristics of the universe that we not yet have discovered.
Why do they over look the part of the universe that does have an electric field?

charge or spin?
@spongah Are you from the 1950's?
Auch das KIT hat am AMS mitgearbeitet.
i thought that there was no such thing as a "galactic edge" and a "galactic core" 1:08
@Hooya2 Thanks, I'll check it out!
It's funny how Science works, the more you discover, the less you know.
@TehOwnerer999 Good questions. I guess we'll need to figure out what dark matter is first.

Paul Dirac was from the Westcountry of England like me!
See, where not all toothless cyder chugging wurzels.
how do you see something you cant see
@Olemguy wouldent that destroy you aswell?
wow, awesome
Respond to this video...
ok im lost as to how dark energy can make a segnifigant portion of the uiverses mass as by definition energy is without mass.
@Blindianboy Stopping scientific research would be a huge mistake. Science benefits humanity by increasing our understanding of the universe and using it to our advantage. And that scientific research could very well benefit the people stricken by poverty, hunger and disease one day.
Science is not the enemy here. Direct your passion towards things that really don't deserve as much money as they are getting. Like wars and religion to name a few. Compared to war, science gets almost nothing.
why is it so f**ing hard to create anti graivity??? should be on the top list of priority. I'm working on it!
@somejackball an average lifespan of over 30 years is a nice addition too
@immunetocommonsense Well... not really... most particles were never anticipated to exist, then found and after quite a while explained theoretically (sorta... for some of them)
Probably not a shuttle, more likely a Falcon 1 or 9.
Fascinating stuff...
Maybe (and before you all jump on me - lol - this is a purely personal theory), all this 'hidden' matter is parallel universes? Or other 'physical' dimensions we're not able to comprehend except to conceptualise mathematically...
Just thinking out loud (well, in text) - lol
It's loose neutrons, baby.
@stevenweir76 Angular momentum. The longer the string on the yoyo the slower it'll move given the same amount of energy.
"Please join us on Facebook for the latest science news and videos:" - I don't want to join Facebook. Please keep staying on RUclips.
I want two of whatever you were on when you said that. I will pay double if you ship them to my mailbox! Plus S&H!
Anti-matter worlds!!! My god how unlikely is that? I cant even imagine the maths, or the situation that would make that possible!
Didn't there used to be various theories about a parallel, antimatter universe with opposite laws of physics to our own?
why can't i reply to comments?
@TomatoBreadOrgasm
Let the world know that you think dark matter will stop poverty and hunger. Let the greatest minds on the planet keep looking for the infinite nothing. Well said, sir.
@MobileThinker I know what you mean. I'd just go to pieces.
this made me hungry
good news folk, I FOUND THE GRAVITON , i did it with a refrigerator magnet a butane lighter and a paper clip.
F-in' Alpha Magnetic Spectrometers. How do they work?
@PVanderston inxna on the arkda atterma.
search inside
we*re going too fast,too slow
I like the idea of matter - anti matter bombs. Suppose thats the next and final step
neutrilino?
And to think... this might all be wrong
Vulcans!
Dark matter is just the invariant mass of counterpropagating photons.
@D34dFilms So in short, science knows what they know, and knows what they don't know; in contrast with pseudo-science that doesn't know that (and what) it doesn't know.
@BalthazzarCH V= (GM/r)^1/2
As r goes up, V goes down.
@g0d0fw4r because you need negative mass to create anti-gravity, something that does not exist. Not impossible, just non-existent.
Could it be that dark matter doesn't exist? Is it possible the mechanism that holds the universe together is not really gravity but electromagnetism? Using electromagnetism as the dominant force sure does solve much of the deficiencies in the standard cosmology model. It eliminates the need for dark matter.

@xeyon LMAO, you would think they would support the cause. But apparently, I guess were just suppose to stay on this rock and don't ask questions.
Atleast we can dismiss our theories, unlike religions. And we can PROVE that the discoveries and theories (some of them, counting out those we cannot prove and have dismissed like the aether) we have made are true!
no such thing as "dark matter", it's electrical, plasma universe explains the observations being made...too simple I guess.
@sensur1 lol, that is so true, I have tried arguing with him about stuff but essentially he never gives proof for anything. But, with help from a co-worker we figured out his sources. It called the Electric Universe Theory, or Plasma Cosmology, in this all his arguments are consistent, though absurd and conjectured theory.
Dark antimatter
so lemme get this straight... we still have poverty, hunger and disease. okay, just checking.
@xeyon They weren't necessarily creationists, they could have just been idiots...
@TomatoBreadOrgasm
don't get upset because the priorities of your favorite people are fucked up. or maybe more people should get upset so we can fix the problems here instead of investigating some shit that more than likely will benefit no one.
@Blindianboy personaly, why should we help poverty and hunger. I'm perfectly fine with lying back and enjoying myself doing nothing about it.
