If anyone is wondering how someone in Warsaw could study the Large Magellanic Cloud when it's only visible in the southern hemisphere, the University of Warsaw has a telescope in the Las Campanas Observatory in Chile

[@MrBigdaddy2ya]

You can pay for telescope time anywhere right

[@movingname3585]

​@@MrBigdaddy2yanot necessarily but yes generally anyone with a giant telescope would accept anyone's money otherwise the telescope would essentially be a giant waste of money cause no discovery from a telescope would pay for the telescope

Woop, woop, I'm from South Africa.

[@MrBigdaddy2ya]

@@KristelViljoen how are things in South Africa

[@KristelViljoen]

@@MrBigdaddy2ya When someone came up the saying, that everything is going south. Did they specifically had South Africa in mind? Every year from an early age, I picked a bright light in the sky on new years eve, wishing on a "star". Once, I came to the realization that the light that I chose was moving way too fast. Imagine the confusion. I remember distinctly were I was, the address of our house and even our telephone number. I was four. My parents thought that I was a weird kid staring aimlessly into the darkness. Believe me, if it wasn't for the fact that they were Lutheran, they would have most probably asked for an exorcism. Since then I have the same ritual no matter were in the world I find myself. I thought I'd be dammed if I choose a shitty star like that again. I missed it this year, my dog became very sick ( Galaxy ) and he later died of cancer. My son's birthday is in October ( the 21st). For two weeks we make every evening a fire ( we have a huge boma) braai some boerewors, choppies, chicken thighs and watch the orionid meteorite showers at night. Again we missed it, he was too busy with his entomology thesis since he had quite a few setbacks with his mosquito population, once ants destroyed his colony delaying his research...again. ( his project is about the effects that light have on the feeding behavior of Anopheles gambia) My husbands birthday is 21 December ( the southern solstice, which we also celebrate with the harvesting of food grown from our own garden), but yet again, a fire broke out at his work and guess who was on call? ( aircon, obviously) Now guess who missed the winter solstice? My husband cut his finger off in a freak accident in June. So yes, please come up with an significant celestial observation in the near future. The only date I can come up with is the super moon 19th of August and it is too far away. I've got to put an end to my unfortunate bad luck. ( My son jokingly just now says that bad luck is like an Remora getting stuck on you. It's not as bad as it seems but you do need to get rid of it. He says no matter how clean you are, they know better. Translating into cancel it with good deeds.)

I wouldn't call it a failure, it's still a significant finding. If ~12.2% of Dark Matter is indeed comprised of Black Holes, then that just adds to our understanding and helps narrow down the search. We'll probably be seeing a lot more "failures" before we're able to focus in on Dark Matter.

[@awesomedavid2012]

I wonder if part of the struggle is that everyone is trying to explain 100% of dark matter at one time. Maybe some part of it is black holes, some part requires MOND, and then maybe some are also new particles

[@user-yu8ur9yi9e]

If visible matter is ~5% of the mass-energy content of the universe, ~12% of dark matter works out to ~3% of everything. Pretty significant.

[@nzuckman]

@@awesomedavid2012 so GR is correct about black holes, but it still breaks in arbitrary ways at low accelerations, AND there are a bunch of new particles that we still can't find after decades of searching? I can't say it's impossible, but it feels like an ugly solution.

[@mikeblalock4116]

Scientists tend to be excited about being wrong, especially if the study was conducted well and peer reviewed. Every time you are wrong, you could be one step closer to being right, and you can help others to avoid being wrong.

[@nzuckman]

@@mikeblalock4116 ruling out places where your car keys are not can only go so far in helping you find them. You could spend generations proving your keys are nowhere to be found on the surface of the moon, but that won't actually help you find them if your keys aren't on the moon to begin with. Similarly, ruling out theories of dark matter doesn't bring us closer to knowing what dark matter is, especially if we fundamentally misunderstand how it works.

More support for space itself being dark matter. Each failure to find what is generally considered to be matter as the cause must eventually lead physicists to consider that space is not uniform but has flow and density variations around which physical matter accumulates.

[@StephenPaulKing]

Have Planck mass black holes been excluded by the data? These would not decay if they have a fractional spin.

[@grnbrg]

I want to know this as well. Even if there's no spin, it's possible that a black hole with a Planck length event horizon would be unable to emit further Hawking radiation, and be stable. Such an object would essentially not interact with normal matter, as scaling a proton to match a model Planck Black Hole that is the size of a grain of sand would give you a proton with a 2 light year diameter. About the only thing that would lead to a physical interaction would be for the Planck black hole to intersect with the event horizon of a larger black hole. In order for such objects to fill the role of dark matter, they would need to be quite common - on the order of 1 for every 30 cubic kilometres, if I remember the math. The problem becomes detecting an anomalous mass of around 20 micrograms, which may be moving at ridiculously high speeds, based solely on the observations of gravitational disturbances...

[@yvonnemiezis5199]

Nice to know this,thanks 👍😊

[@magnitizedlight6536]

Maybe you have explained this in some video that I have missed, but, I'm wondering: Since space and time are related and the universe has been expanding for over 13B years, as space expands, does space, at the quantum level get less "dense"? If so, does this change the rate of time, such that in the first millions of years, time was faster or slower than it is now? Maybe you can do a video to explain if the speed of time is changing as the universe expands. Thanks!

[@merceb9039]

It's a bit more complicated than that. There is a continuous spectrum of masses of primordial black hole dark matter. And the observations exclude portions of the spectrum, so some narrow range of possibilities still remain

[@DivergentStyles]

[@JJ33438]

Anton can you speak sometime about the electric universe filled with charged plasma with charge differentials that can be responsible for all phenomenon seen in the universe. In the electric universe instead of black holes at the center of galaxies it would be a plasmoid consisting of various currents.

[@fronthole]

I wonder if there are gravitational waves rippling through matter at all times.

[@axle.student]

Maybe it's worthwhile working out what gravity is before chasing shadows on the wall :)

[@johnbonahoom2525]

I wonder if all of the matter that is currently identified could be set aside. What would be left? My guess is empty space/time. Plus, since gravitational waves are now preceived. So, what medium is it that carries light as well? If empty space is actually empty, then how do these wave forms (gravity and light) propagate? Sound propagates through air and water. What we call inter galactic space is actually dark matter in my best guess.

[@scottbishop7899]

As we develop new technologies to measure or observe new phenomena we will always be refining our explanations/formulae or creating new ones to explain new ones when making new discoveries. We may find that the way we are applying the physics is not quite right and that this is where we are going wrong or that new physics is required to explain things, we should not be afraid to question old theories and physicists (even if we are wrong) as to do so would hinder us from evolving/refining our understanding. We need to remember that science is progressive (always evolving) and that we believe one thing until we find another to be true, our theories and technologies are still very new in the scheme of things but we'll get there (we are a stubborn lot afterall lol)

[@kakhipudhi]

Looking on Wikipedia's List of Ligo Events, there seems to be a correlation between the mass observed and the distance. It could represent much denser galaxies but also older galaxies. Observations of the Milky Way and the Magellanic Clouds are viewing a more contemporary galaxy. Could this not demonstrate the evaporation of large black holes to vapour (dark matter as black hole vapour) over time?

[@PlanetTwilow]

Wouldn't LIGO measurements experience time dilation, ditto gravitational lensing?

[@FrancisFjordCupola]

One of the big hopes is that there is just one solution. But it's a great deal more logical to expect that there are multiple contributors. I think that there was already an upper limit on the contribution of primordial black holes to dark matter that excluded them from being the single reason for dark matter existing. They were even excluded from being the majority reason.

[@BenD_Bass]

You always mention the dark matter halos surrounding galaxies. Could there be a particle that can only exist in the "empty" space between galaxies?

[@philsinclair7787]

I can't help feeling it is to do with what has actually happened to everything way out there rather than what we perceive that is as it was aeons ago.

[@mikep9690]

Why can "gravity" only be caused by mass? Gravity is a warping of timespace , so what is the effect of the collapsed timespace around a black hole? Maybe instead of a gravity well you get a drum skin? This area of effect would be a sphere of uniform gravity. The inverse square law wouldn't apply.

[@bryandraughn9830]

I wouldn't read the comments either. Love the channel!

[@MaNNeRz91]

[@MrBigdaddy2ya]

Maybe black hole is a strong collection of antimatter like gold antimatter supercluster. Maybe something at the center of it is driving the attraction. A gold antimatter collection bot?

[@NeonVisual]

Is it possible there is a bunch of stable elements in the island of stability which we simply don't have here, but is common everywhere else and throwing off our gravitational calculations?

[@Alondro77]

Nope. Their spectra would be abundantly obvious if they made up even a fraction of dark matter.

[@untouchable360x]

No. It's the island of Epstein.

[@alwayscurious413]

Instead of dark matter I prefer to think ‘dark curvature’ because via GR that’s what we most have in the end game. In other words dark matter might create gravity via GR or there might be an intrinsic curvature that manifests as gravity but which doesn’t need matter to be present. Rotation of a galaxy might cause the curvature like a vortex in the void.

[@tomholroyd7519]

I don't know but "it's made out of black holes" is probably the coolest solution ever

[@michaelaultman5190]

Hmm I gotta question do black holes ever seem to shrink and if so what's form of diet were they on?

[@willythemailboy2]

Theory has them losing mass by Hawking radiation, but it's an incredibly slow process that has never been directly observed. It also works as an inverse function of the mass of the black hole, so the bigger a black hole is the slower it emits radiation. Even the earliest stellar mass black holes will take many times the current age of the universe to evaporate, while supermassive black holes will take many orders of magnitude longer to evaporate.

[@OAN3476]

What if you could counterbalance the vibrational frequency of an atom or particle to make it stand still? Wouldn't that cause it to "freeze" in a sense? What about with magnets? Something like schrodinger's atom. Is it moving, or standing still. Lol

[@jerramygipson6560]

Does this rule out very small black holes then, such as asteroid-mass or smaller? A black hole with atomic mass, might have very little chance of enountering another black hole of the same size, even if they are extremely prevalent. I don't even know how you could detect such a thing. Though I guess if they were everywhere, that would have some effect on the solar system. How is it that dark matter is totally obvious in effecting the rotation of galaxies, but solar bodies seem to strictly obey Newtonian/Einstienian predictions?

[@Thomas-sb8xh]

Yep great work of prof. Andrzej Udalski and his team ( polish team )...Dear Anton as for DM, last discovery suggest that MOND is not done ;)

[@MsSmee2]

I have a gut feeling that the problem is somewhere around this argument. When we measure the observable universe we measure as if space/time does not distort. We can measure things that are not that big or small by traditional means, but we forget that space/time gets distorted when things get very big or very small. How can we say that planet x is y far away? That assumes the time it takes to record the red shift is unchanging. We strait measure that stars are accelerating away from us and we need to invent more mass/gravity to make the math work. The acceleration could just be a distortion of space/time that is not connected to an invisible mass or something.

[@MsSmee2]

Let me try again. How can these two ideas live together. The speed of light does not change. Space/time is not static. It distorts.

[@N8ThaGr8r]

I still think Dark Matter is matter from a previous epoch where the EM field worked differently so it doesn't interact with the EM field in our epoch

We’re still not certain that the final pop of Planck mass black holes happens. If the final pop doesn’t happen, and they don’t evaporate then it’s still possible that dark matter, or a substantial part of it, is Planck mass black holes that will be very difficult to detect.

[@NotOmni]

2:03 How does a tiny blackhole form? I though you needed rather massive stars going supernova to create blackholes.

[@InsertHandleHere968]

Tiny black holes, often referred to as primordial black holes (PBHs), could theoretically form in the early universe under certain conditions. Here are a few scenarios in which they might form: 1. **Early Universe Density Fluctuations**: In the moments after the Big Bang, the universe was incredibly dense and hot. Density fluctuations or inhomogeneities could have caused regions with significantly higher mass concentrations. If these regions were dense enough, they could collapse under their own gravity to form black holes. 2. **Cosmological Phase Transitions**: As the universe cooled, it underwent several phase transitions, similar to water freezing into ice. These transitions could have created conditions where certain regions became extremely dense, leading to the formation of black holes. 3. **Collisions of High-Energy Particles**: In the early universe, particle collisions at extremely high energies could, in theory, produce micro black holes. This concept is sometimes explored in the context of high-energy physics experiments, such as those conducted at the Large Hadron Collider (LHC). 4. **Extra Dimensions**: Theories involving extra dimensions, such as certain models of string theory, suggest that black holes could form at much lower masses than traditionally expected. If extra dimensions exist, they might allow for the creation of tiny black holes. 5. **Collapse of Cosmic Strings**: Hypothetical one-dimensional defects in the fabric of space-time, known as cosmic strings, could intersect and collapse, potentially forming black holes in the process. These tiny black holes would have very short lifespans, evaporating quickly via Hawking radiation, which is a theoretical process where black holes emit radiation and lose mass.

[@tygical]

gas can collapse into a black hole too

[@tristramsnowdon5256]

Dark matter and dark energy are fudge-factors used to explain what we observe and calculate. So something is wrong in our understanding or assumptions Maybe space-time only appears linear at planetary or local group (relatively short) distances, and at galactic or inter-galactic scales it is logarithmic, or exponential or some other function. That could explain a lot IMO

[@Everynamestaken69]

What if visible matter isn’t even a source of gravity or any alteration to spacetime? Im no physicist myself, but if dark matter for sure exerts a gravitational force, what if all matter is simply clumped around this invisible dark matter? It’s already been assumed that dark matter cannot interact with “us” aka regular matter as we know it. Stars, galaxies, and all. Perhaps when we see a star forming or a black holes accretion disk, we are seeing dense clusters of dark matter, which helps allow the formation of the secondary fields that allow “physical matter” to exist as we see it. Is it possible that only within these dense clusters of dark matter can our everyday physical matter take form?

[@Everynamestaken69]

This would also make sense with gravitational lensing. We already know that dark matter can cause a gravitational lens. Which is even more strange to me. If our universe is made up of 85% dark matter, would this not cause us to essentially be looking at a lens when viewing space? I’m no expert but please anyone who knows more fill me in!

[@Badficwriter]

Because there are galaxies that have little to no dark matter. So gravity doesn't require much dark matter.

[@archmage_of_the_aether]

to be honest, as a PC, I'd rather keep the tiny clockwork kracken with the ½ inch antimagic field

[@edwardfortae2350]

I personally think Dark matter isn't even in our dimension. I think it's matter in another dimension pulling on ours or a quantum variation of the universe affecting us here vs us affecting theirs from ours. Our matter we see is the dark matter for that quantum reality.

[@steelgreyed]

I still say Spacetime itself has mass, but repels itself from each other so the overall gravity is zero as it is not allowed to mass up. :)

[@stephencurtis9041]

Hi Anton, In a previous video you stated that an equal amount of anti-gravity and gravity were created when the Big Bang created the universe. So where is the anti-gravity? It seems to me that a whole other anti-matter universe was created and probably exists in the same space as our universe but in a different dimension because if the two universes came together they would annihilate each other. This anti-gravity universe is very likely to also be the elusive dark matter that scientists are trying to find. And it may be that multiple universes occupying the same space but in different dimensions is dark matter with an equal amount of anti-matter and matter universes. This is just a thought but I’m wondering if there is a way to check this out. I’m a musician not a scientist.

[@stephencurtis9041]

I meant anti-matter and matter

[@drsatan3231]

That's just a leading hypothesis but if true it's probable that they both annihilated each other, emitting 100% of their mass energy and then matter formed from that energy via nucleosynthesis after the big bang

[@selasco]

cant be dark matter just the time dilatation (that mass create around itself) creating the illusion of "more mass than should exist"? Like, if a mass need more time to do "gravit thing", it will be perceived, from out side, with more mass

Could it be that 85% of the singularity still exists beyond our visible universe accounting for the missing mass.

They dont have their act together. Lensing is not caused by gravity. More likely cause by temperature, and black holes are very cold.

TBH,i always thought the idea of primordial black holes kinda iffy.We may have to throw all of Hawking's ideas away and start anew.

80% of everything is dark matter and energy, but we can't see or study directly it yet. That sounds crazy to me

SuspiciousObserver's latest video posits the potential of black holes being plasmoids. It is interesting.

Could dark matter be the matter that was before the Big Bang and as the universe expended ie dark matter expanded and that’s why it’s so abundant

[@kimjong-du3180]

Very heavy right-handed neutrinos would be one way to explain black matter

[@doltsbane]

You know there's no rule that says there has to be only one thing that composes all dark matter. It could be that there's all kinds of different varieties of dark matter, each contributing a little to the total.
