What Is Dark Matter? An Astrophysicist Explains | Edge Of Knowledge | Ars Technica

Ғылым және технология

We see evidence for dark matter everywhere we look but proving hypotheses around it has been exceptionally difficult. Astrophysicist Paul Sutter explains everything about this mystery in a way almost anyone can understand - what we know about dark matter, what don’t, and how we’re trying to find out more.

    Even if I take nothing else from this video, the notion that *neutrinos are dark matter so we have proof some of it exists* is mind-blowing. Mostly mind-blowing because it's the first time I've heard this, I still thought dark matter was only hypothesized, while I very well knew about neutrino-detecting labs.

    Yes, it baffles me how rare that is for someone to say that simply and clearly, because it is the only thing precluding more fundamental questions like "isn't it possible that your models are just wrong?" that many people naturally have upon hearing everything else commonly said about Dark Matter and Energy.

    Well neutrinos are more like dark-matter’s less shy relative. Even if neutrinos rarely interact with the other matter - they still do interact. The “true” dark matter doesn’t interact yet has a large gravitational impact on the normal matter - that’s what makes it a lot more strange than neutrinos!

I heard from another presenter you probably know (Dr. Gay) that in addition to the lack of mass neutrinos are too hot to be a candidate for DM. Is there some theory that says massive neutrinos would be colder and a better candidate? One last question: Do you lecture at your university and are your lectures on-line?

    dark matter does not interact electromagnetically, so it cannot collide with other matter and does not affect light, but it does interact gravitationally which is why we can detect it in the first place (the example of galaxies spinning faster than expected). Gravity is by far the weakest force so this makes it very hard to detect dark matter particles but easy to see their combined effects on galaxy scales.

    Dr. Thomas Charles Van Flandern, an expert in celestial mechanics, but apparently politically constrained in what he could say, indicated different frequencies are due to different light speeds, and at the time it made no sense to me as I took it to mean he was saying there were multiple light speeds at the same point in space. Eventually it became apparent to me that lightspeed could be gravity sensitive, that it gravitationally speeds up to gravitationally blueshift. After that, what Van Flandern said made perfect sense to me, he was talking about the same photon under different gravities. The only argument against variable light speed might as well be attributed to a revolutionary flatworm creation of bent-spacetime groomers, a theoretical decay effect of light bending, as if light and gravity fields cannot exchange energies directly.

    making a repeatable experiment with observable and replicable results most certainly proves a theory to be correct or incorrect or at least correct to our level of measurement and understanding. think about something simple like theorizing how gases change volume at different temperatures. do a bunch of experiments, plot the data, and you'll see the relationship is PV=nRT. before Boyle conducted experiments to prove his ideal gas law, it was a theory as to how the items functioned.

    A hypothesis will be shown to either hold or not hold, i.e. be correct or incorrect. If it is shown to be incorrect, a new hypothesis is formed. Once you gather enough understanding of a phenomenon, you can formulate a theory - a logical/mathematical model of how that phenomenon behaves. The theory should be able to explain observed behavior and accurately predict future behavior as the parameters change. If behavior is observed that does not fit with an established theory that's worked reliably up until that observation is made, a lot more investigation, measuring and examination needs to take place to make sure the observed results are accurate. At that point, the theory will need to be adjusted (maybe it was missing a parameter that had very little contribution up until now?) or a new, better theory needs to be formed. Even theories that don't work in extreme scales can be useful for normal needs, as they are usually simpler than a more correct theory that works over a greater value range - such as Newtonian mechanics and general relativity. If you go very large (planetary/stellar scale), Newtonian mechanics will give incorrect results, whereas general relativity will match reality better. Newtonian mechanics will still be accurate enough if you need to figure out the mechanics of a car on a hill, or the trajectory of a cannonball. The third term in this group is "law" - and a law of mathematics or physics is usually a (relatively) simple observation that has never been shown to be false. For example, energy in a closed system will remain constant - it can be moved around and it can change form, but no new energy can be created and no energy can be destroyed. There's a multitude of international physics prizes you can win if you can demonstrate a law of physics being incorrect.

    I have many questions mainly to do with observable phenomena that we should see more of that we don't, or so I believe. 1. If dark matter interracts with gravity, should it or why does it not attract itself to create dark matter bodies like planets or stars? If it does, shouldn't we possibly see galaxies with invisible cores or with significantly less stars for their size than they should? 2. If it doesn't react with its own gravitational field, then why would they interact with gravitational fields from visible matter. Would that then make dark matter a universal filler like aether? If so, why would galaxies stay connected since the force of gravity would be diffused throughout the universe and galaxies are only traveling through clusters that make them stable but then they're annihilated once they leave the higher concentrated areas? 3. Assuming that dark matter cannot react to the gravity fields of itself but can react with with those made by visible matter, then wouldn't we see different concentrations in planetary cores? Why wouldn't we see celestial bodies with significantly more gravitational force than others of a similar or exact same mass? Would it even be possible to calculate a universal gravitational constant associated with visible matter? On that note, if it makes up 80%-90% of the universe, wouldn't we also be able to detect more black holes and even black holes that don't have enough mass to sustain the gravitational force necessary to sustain one to begin with? Even if they're small enough that the Hawkin's Radiation, then shouldn't we be able to detect smaller spontaneous black holes being created all the time? 4. Assuming dark matter has the properties of the 3rd point, then we could assume that in the creation of the solar system that there would be a ring of it orbiting around the Earth or any of the other planets or even sun (or a sphere if it can't collide with itself) creating a gravitational field that would be easiest to detect with a sensor on a satellite? On that note, if it can't collide with itself, wouldn't there be a similar sphere around the galaxy that would have the mass necessary to rip stars and systems out of their current orbits around all galaxies, in different vectors so that disc-shaped galaxies would be rare? 5. How do we explain the existance of galaxies without dark matter, ones where their mass is sufficient to sustain orbit? Theories persist that their dark matter was stripped by nearby galaxies, but- considering the abundance of it-why would it leave any of the visible matter behind instead of the galaxies merging? Please help me understand the theoretical properties of dark matter since I've had a ridiculously hard time finding any information on the subject, instead, just the evidence we've seen that leads us to assume its existence.

    All matter and energy hold the potentiality for spawning life which leads to variables whose actions can be altered based on their observation of the universe. Dark matter cannot form in such a way that it’s byproduct (life) can become affected by observation of the universe. If we break all life down as nothing more than matter and energy with varying degrees of behavioral predictability, we find that reacting to the universe is itself the missing variable in the equations.

    Perhaps, if you account that Matter and Antimatter werent the only ones in the beginning of the universe, you may know why it wasnt annihilated. In the beginning there was 5 types of matter: 1. Very Heavy-Matter ( Interacts with Strong Force / Magnetism ) / 50% 2. Heavy-Matter ( Interacts with Weak Force / Gravity ) / 30 % 3. Common Matter ( Projects Magnetism / Gravity ) / 20 % 4. Very-Light Matter ( Dont interact with Matter/Antimatter ) 5. Antimatter ( Rarely interact with Matter, due to Heavy Matter forces, and does not have forces property. ) You know that you cannot destroy matter, so you are missing that when an Anti-Particle hits its Particle, It unleashes energy which decays to Very-Heavy Matter / Dark Matter. This can be proved with the expansion of the universe itself.

    We are beginning from the assumption that Relativity is correct. But if it can't explain the existence of 85% of matter of the universe, is it possible that the theory is fundamentally wrong? Instead of looking at the mystery of the 'dark matter', could it be that our glasses with which we were looking at them was faulty in the first place?

    Given what I've learned about dark matter over the years none of the detection methods make sense anymore, we're trying to detect a matter type we cant see or interact with by looking for it and seeing if it interacts with normal matter. We know it interacts with gravity and therefore time because spacetime but we dont see it interacting with much else. Unless it interacts electromagnetically, say by causing chaotic perturbations in electromagnetic fields then gravitational detection may be the only way. My personal theory is that it's either just a new form of matter created by black holes and replacing normal matter as a new study suggests, a form of matter which sits in a higher dimension therefore it only interacts with certain fields such as gravity or it is a form of matter which isnt even in our universe, that we see actual matter but only the gravitational shadow of it from another universe overlapping with ours in a weird almost metaphysical way Also what if there are many different types of dark matter akin to our normal matters periodic table

    Assuming the assumptions made in interpreting the measurements are correct, which implies there is a lot of "extra invisible mass" in the universe, then that "dark matter" is simply ordinary matter which is too dark to observe by current instruments! For example, comparing old photographs of galaxies, with modern deep imaging, reveals far more faint material in the outer parts of all of the galaxies. This explains that the "discrepant" galaxy rotation curve rates found by Vera Rubin are due to faint ordinary matter, not some elusive exotic "dark matter" which extensive search has failed to identify.

    *Speaking of thought experiments,* The speed of light is merely a mathematical construct. In reality gravity drops off exponentially outside of a galaxy allowing for time to speed up and the other thing that happens, which people seem to forget, is that less gravity also allows for distance to be expanded, which results in less distance compared to our contracted distance inside of a galaxy. So less gravity allows for our observation of the light to travel 186,000 miles at a faster rate of time over an inflated measure of distance relative to where we are inside of the galaxy causing the speed of light to be greatly increased relative to where we are in a more contracted measure of distance and a slower rate of time if GR is true and GR is now more of an observation than a theory. No dark matter and no dark energy required.

    If regular matter equals energy then antimatter also equals anti-energy. What if this anti-energy state doesn't interact with the regular matter/energy, the way anti'matter' does, but it behaves like dark energy instead? What if dark energy is anti-energy form of antimatter?

    Hello, im doing some research into why dark matter is predicted. I understand that the origin is the discrepancy of galactic rotation curves or simply the speeds of the orbits dont calculate correctly taking into account the mass density. My question is this, is dark matter solely based on that and that only, the speeds were measured and its not normal. Anything else or is that it?

    I feel that, talking about dark matter and Scientists saying it exists but dont completely know what it is and still haven't found an explanation for it but they do think that it exists. All this just resembles a common question that almost every person has asked them selves "Does God exist?" . We can all feel that God exists and there's a lot of evidence that explain that God exists but most people just ignore that feeling because they feel there's no true way to prove that He exists. There are People that actually believe he exists but find it hard to explain his existence but they do have a gut feeling he exists. These two subjects are completely different but you can compare the similarities.

    They aren't really comparable. Dark matter is an unknown concept. God is an *unknowable* concept. It's entirely possible within our understanding of science that we could one day observe and experiment with dark matter, it's just really difficult, and we've been unsuccessful so far. We know this because we have measurable boundaries for what dark matter could be, and a reason to suggest that our data isn't wrong and there is a measurable phenomenon happening. One day we could find a way to observe things withing these criteria, we could theoretically find dark matter. With God, *all you have* are feelings to go off of. God is a nebulous concept as-is. Even the people who believe in God can't agree which God it is, or what he is. It's safe to assume that even if God exists, we can't really consider him in the field of science, because God is unstudyable by nature of what God is. Which is someone or something who is *beyond* the rules of nature. You can't measure by the rules of nature, if that thing is not part of nature. And if God is indeed part of nature, why has no evidence whatsoever surfaced yet? Well, maybe he's real we just haven't found him yet, right? Well, there's a logical fallacy in that. A hunch isn't enough to go on to develop a theory, so until some kind of repeatable, measurable, experimentable evidence surfaces of God's existence, we can't consider him as real.

    For me it looks more in favor to a mond theory. It seems like the gravity force as we know doesnt fit for distances for far beyond 10k light years. Everything actually and simply fails after that, therefore the anomalies with all galaxy rotation curves, clusters and deep universe - therefore dark matter, therefore dark energy. Additionally, we still cant combine gravitational force with other fundamental forces of nature. Thats very obvious for me that our thought of gravity is simply wrong. I am very sure of that. I think gravity as we understand so far with all its calculations is just simply a side effect caused by something else that we havent discovered yet, but requires to extend. The gravitational lense must be caused by some other effects, if you compare it in the bullet cluster, the fields at that scale must be influenced differently than the gravity field of Xray smooth distribution, and the momentum could also work differently, also the expansion of universe could cause some anomalies in between them. Sticking on dark matter and dark energy is like sticking on a geocentric view. I think the accelerated expansion of the universe is a normal thing, just our understanding of gravity is simply wrong. As there was no ether either, same also no dark matter

The con"cern" is (like what I did there?) we find one...or two particles lets say out of hundreds, or thousands, or millions and get excited and start playing with forces we are ignorant to and presumptuous in our small scope of knowledge. I just hope zeal doesn't overtake patient, prudent science

    Thanks, other dimensions with different laws of physics seems likely because our universe has certain values tied to the laws of physics (stong force, weak force, etc) that make our universe with it's stars and planets possible. Now that could be because of intelligent design (sounds nice, but unlikely), or there are multiple universes and we happen to be in the one where these values make everything we know possible.
