@@isaacarthurSFIA Isaac, Thanks for the episode. I have come up with another model that does away with, or maybe explains dark matter. It proposes that gravity is caused by the mass in alternate universes faintly attracting mass in this universe, via the strong and weak atomic forces effecting mass in this universe. Yes, *it can be tested.* How does my model explain gravity that reaches far into space? Well, the other masses like planets, etc are mostly all disintegrating in those other universes because of their varying fundamental constants, and-or the *vacuum decay* of those universes. So, the *gradient of particles* expanding in the other universes would explain the gravity "field" we see. Light could bend around masses because it's actually refracting through the hidden, expanding mass. But to match observations, the masses in basically ALL the other multiplying universes may have to be exploding and flying apart. It could be tested by setting up a large, movable mass that would be moved if a random number generator picked a certain number out of a large set, and see if there is a delay, or anomaly in the change of the faint gravity field where the large mass *used to be* (since in other universes, the mass may not have been moved). I cannot run the calcs to figure out if they match observations, but I invite others to do so, if they would like to.

I remember once hearing a theory about Dark Matter being the gravitational "shadow" of another universe, so maybe if you were able to detect it directly, you could theoretically map another universe or dimension. Taken to the far extremes, perhaps you could find places where the boundary between universes was weakest and then find a way to break between them.

[@tobyharrison4702]

Well that’s a fun concept. Weird that no sci fi (I know of) has tried that concept.

[@echoecho3155]

@@Ozzy_2014 Isn't that the fun of sci-fi, though? Getting to play with scientific concepts - even the outlandish ones?

[@Dragrath1]

They have looked for this sort of effect under classical GR conditions but there the bleed through should have the effect of slowing down gravitational waves giving gravitons an effective mass as these perturbations can only travel at the speed of causality. However I think it is still possible if the dimensions separating us from these shadow universes are quantum mechanical in nature. In particular I wonder if all or some of the "dark matter" is really the combined leaking gravity from the "many worlds" view of quantum mechanics. In this case the halos of dark matter would be like the quantum mechanical cloud of the electron around an atom all the other possible states of that region of spacetime propagating through from their own entanglement cones. I got this idea from the formalism of Wolframs multi-wave hypergraph model for fundamental physics based around computation as it adds another type of dimensions based around all possible unique states. Since in that model every "world" overlaps in Einsteinian spacetime only separated in branchial distance where the speed of entanglement has units of power and is much larger than the speed of causality thus it shouldn't be subject to the slowdown that doomed the old shadow universe hypothesis as the new variants would be able to travel faster and catch up with conventional gravity rather than dragging the waves down. Note that these branchial worlds are able to collide in this model with those collisions representing two or more worlds converging onto the same state which has the trippy effect of making the past a quantum superposition of all indistinguishable past histories. Pretty trippy.

[@alexalekseev238]

This is the best channel about science. A lot of interesting and new information.

[@Gnomenclature]

In the parallel realities episode, it's mentioned that the weakness of gravity may be due to gravity's strength being stretched across multiple dimensions. Is it plausible that dark matter might just be the gravitational effect of mass from other dimensions interacting through a force of gravity that transcends dimensional barriers? Mostly a thought I had for a science fiction setting, but I thought it might be amusing to discuss.

[@theonlyrealcdub]

Yes, that is something I thought of. We would not be able to perceive or even measure matter at a higher dimension

[@LetsgoPats56]

Hypothetically do you think if we ever found a way to harness dark matter, we could use it to manipulate time due to gravitational time dilation?

[@mishkosimonovski23]

So potentially, we can take a spoon of neutronium surround it with large amount of Dark Matter, and it won't disintegrate and yet we could have access to the neutronium cuz Dark Matter is not standing in the way....we can use it for gravitational field.

[@Reddotzebra]

So if that last hypothesis is true we might actually create Timelord tech in the future.

[@tastyfrzz1]

Latest theory is that it's in the fifth dimension that was identified in Kaluzas idea in Einstein and Bergman's 1938 paper on gravity called "On a Generalization of Kaluza's Theory of electricity". In here electromagnetism results from a gravitational field that is polarized in the fifth dimension. If that's vtru there has to be a lot of something in there.

[@Skandraken]

I thought the purpose of MOND was to strengthen gravity, not weaken it. The version I remember is that at some critical value gravity transitions from being an inverse square law (1/r²) to an inverse law (1/r). If gravity were weaker, then we would need an even larger dark matter fraction to reach the galactic orbital velocities we see, making our problem worse.

[@_Fluffy]

Krikkit is exactly where my mind went when you started talking about using dark matter as planetary defense. I love how wacky physics can be.

[@Skylancer727]

From what I know, the best theories for dark energy to me would be the GEODE or "Generic Object of Dark Energy". It's basically the idea that along side black holes are GEODEs which look and act similar to black holes however are comprised of dark energy and therefore grow as the universe gets older as connected to the red shift of the photon. It could also explain why the collisions between black holes observed are really off of expectations being sizes that should be really uncommon as for the smaller stellar mass ones have barely been observed. As for dark matter, still banking on the axion. It's a particle that basically has to exist to solve quantum chromodynamics and it so far has had the most tests back it up. Recent studies of neutron stars show the increase in gamma rays expected if the axion exists and there were a couple of tests that showed minuet signs of detecting it (though those could be noise from false positives).

When dealing with quantum physics there are a lot of things we don't know, and its important to preface these things with terms like "as far as we know" so people aren't misled. I'm constantly running into people here on youtube who think dark matter is a sure thing when it isn't.

[@ThanksIfYourReadIt]

Im pretty sure dark matter just like a lot of other stuff is simply a place holder until more accurate measurements arrive. Like if we would count togather all dust, radiation, rogue planets, and other stuffs it could add up to the needed gravity easilly. But i mean really accurate, like counting togather the effects of gravitational wave fluctuations on planetary bodies and how it affects theire trajectory, and we talking about waves generated by not just the core but all other dense bodies, like the very common 2 star systems. If we would add up ALL this crap it might cut the bill. But even then we can still think about ambient forces like light push against planetary bodies in clusters where an abaundance of galaxies can be found in certain directions that creates a net extra force over a bigger patch of a galaxy's shape then it does when the same stuff spins around the other way. Angles can be covered here. AND STILL we could throw in theorized electromagnetic force is different in other parts of the visible universe due to the avarage allocation of mass in regions. Such thing could have a big inpact how matter gets affected by kinetic force other then gravity in big amounts like galaxies. This is computation and observation on such a level it might never even happen, but just might add up to the missing values. Our conciousness is rather parrallel, so not being able to think multiple reasons causing one big thing can be a known hinderence why we still call it dark.

[@robertanderson5092]

According to special relativity the closer to C that something moves the slower its clock. A photon travelling at C experiences 0 seconds between emission and absorption.

[@TheTonyMcD]

@@robertanderson5092 Exactly. That's why I like to imagine that photons are inherently unstable. The only reason that light exists in this situation is because photons don't experience any time in which to destabilize.

[@TheTonyMcD]

If the universe were created, by god or a simulation or whatever, perhaps the creator had severe problems trying to get the photon to be stable long enough. Maybe their solution was relativity, and the speed limit of the universe. They couldn't make photons last long enough, so they just made them not experience time. It's just a neat little thought experiment.

Isaac Arther and others like him, I mean in general. Obviously there's nobody like Isaac😁. These guys are a treasure to humanity in a time that desperately needs them. They give rational people, people who can't help but to dream about all the amazing things in humanities future in an actual possible kind of way access to the kind of expertise required that aren't always the most accessible. Humanity has alot more knowledge and power than the ufo ancient aliens crowd seems to know of. The idea of building scifi like spacecraft, megastructures, huge space habitats, modifying our genes for added capability, build nano structures that can do all kinds of cool shit. These things seem almost like magic but are actually possible within the laws of physics as we understand. That should be so much more exciting to people than just randomly assigning magical powers that are likely impossible to explain the next ufo sighting or weirdo conspiracy. A ufo that's likely a duck or a drone or a balloon or some other mundane thing in a slightly unusual circumstance. Or a conspiracy started by someone with a financial or other motivation to make u believe them.. Joe Scott used to do ghost investigations, Bigfoot, UFO's all that stuff. He got into it as a kid and was still interested as an adult. I was the same, I had all those ridiculous time life books that covered all these supposed incidence. Then he started investigating actual scientific topics and learning all that goes into them. Meeting the people that devote their lives to science. And he started to realize how stupidly easy it is to fool people with an unusual light or sound or anything unexpected and he had his come to Jesus moment as we say down south. Now he understands that's theres really just no evidence to support any of that stuff. He changed his mind even though he had to feel a little silly maybe even embarrassed but he admitted it all the same. That should be celebrated. It is a good thing to change your mind based on new evidence. We need more people like that willing to admit when they were wrong and try to correct how they got there in the first place to hopefully benefit you and I and make it easier for us to follow the example. The world is a big scary complicated place but it's the one we have. We should rather be happy to know an uncomfortable truth than believe a happy lie that just pushes the buck to someone down the line to deal with.. These guys and others like them should be part of public school curriculum. Watching this stuff doesn't just tell you what to know, it teaches you how to know anything for your self in any topic. It teaches how to know if someone is worthy of trust or just a good con artist. Humanity needs these things now more than ever. Turns out that making all of human knowledge available to everyone without teaching them how to think critically first just makes people dumber, more tribal and more primitive. You can find support for any crazy thing you want to believe online. But you should have the skills to decide whether they are worthy of your trust. Isaac Arthur gives people the freedom to dream about our magical future without any magic required. It's all just science and engineering. That should give people such optimism and hope for the future and a little more faith in expertise. If more people were interested in actually knowing things instead of just believing what they wish was true we might have a chance to fix the problems we have created through our ignorance. Guys like Isaac Arthur, Joe Scott, Tim Dodd, Mick West and on and on. I hope they know how much we appreciate their work. It might be more important than any of us realize, Thank You.

Maybe dark matter doesnt produce as much gravity as we think Instead spreading out More diffuse Allowing the gravitational well to be far further than the baryonic matter in a galaxy

[@miaththered]

Huh, I actually watched it before commenting for once. Thanks for this, Isaac!~

[@debyton]

In MOND how can gravity be different far away? Far away from what? Far away from one location in space-time is nearby some other location gravity needs to be invariant in space because every frame is a valid frame. How can gravity be one thing at the center of every galaxy and different at its edges? The MOND gravitational mechanism would have to be somehow informed by what we call the center vs the edges of a galaxy and also every other relevant distribution of matter as well.

[@cmbaz1140]

i wonder if dark matter is the result of anti-energy interacting with energy kinda the "reverse" of matter and antimatter becoming "energy" by annihilation ... resulting in "matter" just as mass with zero momentum , spin or charge.

[@archlittle6067]

What if a K3 civilization would use the entire mass of a galaxy, not just its solar energy? Assumptions: A Kuegelblitz (KB) is possible for a K3 to create. These would power the K3 habitats and solar power would no longer be needed. Using the methods described in your Starlifting episode, the mass of the star could be slowly "mined" away. Instead of using 1% of a star system's mass to create McKendree Cylinders, i.e. without the star itself, 100% of the mass might be utilized. The advantages are obvious. Further, the habitats would be mobile, using each hab's KB as a drive. If a star system's habs were spread out over a cube 6.2 billion miles per dimension, then a similar cube with one light year dimensions might contain a billion star system's worth of habs. The entire mass of the MW galaxy could be concentrated into a cubic volume less than 10 lys per dimension. This would speed communication and therefore governance in the K3 by several thousand times. Theoretically, two random K3 citizens could meet in a matter of decades instead of traveling for eons. The K3 might assemble it's habs near the natural BH Sagitarius A* to stabilize these in a halo. This ultimate megastructure might be called a "galactopolis". Sorry for going off topic. If you enjoy my musings, then perhaps this idea might be part of a future episode. Thanks for your indulgence.

[@jtgus]

It seems to me that dark matter is probably composed of multiple things and/or particles and is not a single uniform substance. Each of those sets of particles will likely have their own specific uses just like elements and known material particles have their uses.

[@Paroll123]

Have you seen the new evidence that points to the non existence of dark matter? Wont pretend I exactly understand it but would love to know your opinion/thoughts on this

[@lucky-segfault]

Short explanation: The study you're referring to most likely indicates that one of the things dark matter could have been was just disproven, but either way there's still something that sure does behave like a bunch of extra invisible matter in galaxies so what exactly that something is is still up for debate. Maybe gravity just gets weird on huge scales and it looks like extra matter to us who don't know better? Idk but there's definitely something going on, just what is far from being known for sure

[@darrekworkman8685]

There is a big difference between indirectly observation and hypothetical 'observation' that is only necessary to make another hypothesis work. Dark matter is a mathematically necessary for current theories of how the universe works to be valid. It is actually far more probably that the math is not correct than for dark matter to exist magically filling the wholes in the current theories. Quarks as a scientific theory have been shown to have predictive value in experimentation. The core and mantel haven't been observed, but magma has and again the theories have been proven to have predictive value. There is no predictive value by which to test if dark matter or dark energy is a valid hypothesis. It is a hypothesis that resulted from the observation that the universe doesn't behave the way scientist thought it did so the invented a 'substance' to fill the 'void'. Some examples of Clarktech are more reliable.

[@antsalberta7526]

Why doesn’t dark matter accumulate inside celestial bodies? If there is so much of it, certainly planets and stars should have trapped it inside their gravity wells. Which in turn would increase the weight and then increase gravity and increase dark matter attraction.. especially with a star, since dark matter doesn’t get influenced by normal matter, it wouldn’t feel the same pressure from the photons inside the star… and wouldn’t be pushed out? Or am i stupidly wrong here.

[@barefootalien]

Heh, funny you should mention a lot of these things... If you hadn't heard (which I mean, I'm sure you have), we _do_ now have evidence for a fifth fundamental force. We also have detections of gamma rays of about the energy we'd expect of certain WIMP particle decays, in about the right places. We _also_ recently discovered evidence that dark matter _is_ clumpier than previously thought. All this in the last two months or so. I couldn't help, as you listed all the things we might detect but haven't yet, but think of all the recent papers about the discovery of exactly those types of things. Oh, and had you heard the theory (that fits the evidence quite a bit better) that our central black hole may not be a black hole at all, but rather an extremely large, dense clump of dark matter?

same could be said about neutrinos and the higgs boson for the last 80-100 years. dark matter plugs holes in our general understanding, and it cant be discarded until we find better observations to fill those holes, just like the higgs field and boson did. whether dark matter turns into the current day aether, or next centeries higgs boson will only be determined after the fact. no matter how many outlandish or wrong theories we currently have about it.

Science moves forwards by falsifying itself. Theories are the models we have that have yet to be falsified in the areas they claim to represent, but all will eventually be superceded. Plus, a lot of the models we have superceded in physics, like Newtonian mechanics, are still very useful in the regions they apply to, even if some like the luminiferous æther have been put to rest. The funny part will be if anyone desperately clings to the idea after something more parsimonious takes its place, not that anyone ever believed it at all, to the extent that one can believe in a hypothesis that is explicit about its uncertainties. The people who will be the target of either mockery or hatred in the future will be the ones who deny climate change, suppress science, or insist on misuse of resources through wasteful things like the military industrial complex. In the far future, the idea of a human person not having access to food, shelter and healthcare will be laughably barbaric and cruel.

Lol, W.I.M.P.s - and people say scientists are bad at acronyms XD

[@michaeljf6472]

By 18:00 it seemed like you're describing Mass Effect. In-universe most of their advanced tech is based on element zero, which manipulates dark energy to create gravitational fields. They use it for everything, FTL, biotics, gravity plating, shields

[@cocoabutt1711]

I'm starting the Flat Gravity Society. I always wanted a cult.

[@Declan-pg8cg]

It has a certain attraction.

[@empireempire3545]

The name has lots of gravitas to it

[@jameskitner9368]

Can any one join? Or do you have to be drawn in?

[@Rattus-Norvegicus]

So long as I receive human contact I'm in.

[@silentwisdom7025]

There's plenty of fodder for the punchbowl these days. Just try and do some good with your influence, we all need more positivity.

Dark matter matters..

[@tobyharrison4702]

Hey a topic I asked about in a stream is now a video. Wooooo. Thanks Isaac.

[@xassix]

*sigh* Why are there so many people who just dont understand that believing your own gut feelings to outweigh scientific evidence is NOT the same as critical thinking?

[@nosacredcows1810]

You left out the sixth known type of energy and possibly the most important one of all,Caffeine blessed blessed Caffeine.

[@ruileite2634]

WimpTech is not a good name for your futuristic tech company. Rebranding needed!

[@thejimmydanly]

After spending a good portion of the last few years binging all of your videos, trying and trying to catch up, I'm finally all caught up and watching a new episode on the day it comes out.

[@Mike-sp6tt]

Another fantastic video. This is seriously the best channel on KZbin. I’ve been interested in aliens and the Fermi paradox since I was a kid, and When I discovered Isaac it’s like I struck gold. As a science communicator you’ve enlightened me far more than any other individual in the field. Thank you so much once I get a new job I will give back to you.

[@yankoaleksandrov]

When I drink too much or don’t feel good I always listen to this it’s very calming

[@chrisgriffith1573]

I think "dark matter" technologies will have more to do with making existing technologies far more "direct" in their path to our goals. I believe dark matter to be more of a property to our universe that permeates everything already... harnessing it for direct things would be silly, like making light shades around the Earth, it would take more energy and resources to produce than benefits of return for the investment.

[@thumb-ugly7518]

I love this episode. It reveals to me the vastness of our ignorance, and the potential to learn. I want to write a sci/fantasy. I’ll probably bastardize dark matter much the same way as Quantum Mechanics. Good stuff.

[@rojaws1183]

Anti matter is sooo last year. Here on Isaac Arthur we build with dark matter.

[@ArmandsVilnis]

i think ill have to re-watch this one several times before i understand what were talking about here. nonetheless thanks for the awesome videos mr.Arthur!

[@Deadlyish]

The biggest question I have about dark matter: can you make it into a drink and a snack?

[@john849ww]

Will you be adding a "join" option on KZbin as a way to contribute to your channel?

[@TheodoreIchabod]

23 seconds ago the internet got smarter

@@jessicalee3929 guess we do

[@gliese832c]

At the end of this episode you mentioned that if dark matter is crunched down dimensions, it could be used to store time. What the heck is that supposed to mean? My brain explodes just thinking about it. Can anyone explain it to me please?

[@Ozzy_2014]

Time passes relatively to ones motion through space. If you can control the warping of space time you could concibeably create bubbles of time. A slow time bubble would give you somewhere to exist say with a star still burning long after the universe has fallen to heat death. If it could do more.... Well I recomend the 1991 Novel Timeships by Stephen Baxter. A sequel to The Time Machine. They answer some big questions. What could a intelligence do that is functionally immortal and knows time travel exists. Knows the universe is dying of entropy. That intelligence would be well motivated to find a way to escape such a universe. Well perhaps this is how they will.

[@paulmahoney7619]

As an avid fan of the Stellaris mod Ancient Cache of Technologies I salute this video and hope you will make an episode about how we can harness the souls of stars themselves as an extremely potent source of power and incredible technology!

[@KlavierMenn]

First we master Tachyon Sensors, to finally grasp Dark Matter Drawing. Then we need very good scientists with specialization in Particles, Materials and Military to learn how to Generate, Contain and Apply Dark Matter and then, finally we can attain the Dark Matter Reactor. Suffused with a new way to power our society, Superior Constructs are erected, with Void Palace being the mark of Dark Matter Governance!

[@matteodelgallo1983]

GRASER is already taken! It's for Gamma Ray Amplification by Stimulated Emission of Radiation. You can have GASER though, I guess

[@lucasharvey8990]

Right as I'm on the way to school. See ya in half a day.

Don't worry guys, we just have to knock over some Fallen Empire and research the debris! Wait, I forgot this is real life, my bad.

In fact they are timeless. Litterally.

I'm one of those content creators who folded. Teeny channel, but still :) Will maybe get back into it this year. Great video as always Isaac, keep it up. Lots of love from South Africa.

The last time I was this early I was watching dark matter being made at the Big Bang

You should put the link to the nebula videos in the description. Up and atom etc.

There is some dark matter in my Kitchen and I don't know how to treat it. It demanded animal sacrifice, is this normal?

[@aleisterlavey9716]

@@jessicalee3929 hm... i fed it a bucket of fried chicken. Now it wants a gallon of Gravy. I fear, if I start feeding it People, it demands Chianti.

[@highfive7689]

Recently I read some articles on the postulation of Dark Photons and Photon decay. Since energy can not be destroyed ( A Big if - but most of our understanding of physics rests on this idea) Can we then suggest that when energy has been discharged below the observable range, can we postulate that Dark Matter might be related to this range level of energy way below radio waves (below ELF). Hence not seeable or detectible, due to our level of tech. Might even join the gravitational waves in space.

[@SepehrNaserkhaki]

In before what we call dark matter is just gravity generated by the fluctuations of the higgs boson field

[@silentwisdom7025]

Has anyone ever taken a suggested video tour of this channel? I bet you could watch for weeks on end skipping further and further back in the channels history. I tried this once with pbs space-time, but got bored.

[@XellithUS]

I saw a video the other day talking about how dark matter might not exist at all, and that the influences of dark matter might just be the influence of nearby galaxies and the rest of the universe. I THINK DrBecky did a video on it.

[@SerPapus]

It could just that the whole universe it self is running on a computer

[@mikeloeven]

There is no stealth in space! Turns insubstantial using dark matter WAIT THAT'S ILLEGAL!!

[@barryon8706]

I just found out that dark matter doesn't exist by looking through comments on KZbin. Do astrophysicists use KZbin?

[@comiccat4650]

Science is wild. "We don't know how bisycles or planes work but we use them anyway every day and we have never deteckted a single particle of dark matter and only know of it because the things we see don't add up bute here is how to use it anyways"
