the simplest answer is normally the right one and it is been proven that no matter how hard of a vacuum we pull there are virtual particles popping in and out of existence so wouldnt it make sense that the pressure involved with virtual particles popping in and out of existence throughout all of the universe could create some form of expansion associated these virtual particles and wouldn't it make more sense that dark matter is just brown and black dwarves and micro black holes along with a higher density of virtual particles existing in one area versus of another no need for dark matter or dark energy it's just normal matter that is dark and normal energy that is constantly being created and destroyed and is proven.

This dark matter energy hybrid idea is clearly garbage. The guy didn't even mention the fact a new force is still needed toe be emitted by dark matter particles... We know if they were same charged particles (perhaps even positrons) we'd be able to see them, so not a repulsive electromagnetic halo... Neutral matter does not repel electromagnetically... -- The other option is even less feasible: - galactic halos of neutral dark matter with continuous outward momentum, in a dense enough stream to guarantee enough repulsive collisions between adjacent dark matter galactic halo particles occur.. These collisions then need to propagate the collision force back in the opposite direction, through this neutral dark matter stream... The idea is absurd... It quickly gets to the point where a near solid dark matter halo must be continuously emitted. This breaks many physics laws.

@@PrivateSi There are problems yes but it does far better fit observations which show that whatever dark energy is if it exists it is non uniform i.e. inhomogeneous in the sky. Of course as the evidence against the validity of the assumed large scale homogeneity aka the cosmological principal the Need for such an explanation decreases. After all the cosmological principal is and always has been an *assumption* that allows the reduction of Einstein's Field Equations(EFE) to the vastly simpler Friedman Equations which unlike the potentially chaotic EFE have a analytical closed form solution. With the observational evidence from large scale surveys like SDSS and 6dFGS ruling out the existence of such a cosmological principal out to at least 300 Mega parsecs (Mpc) well beyond the cosmological principal's assumed 100 Mpc homogenous frame it becomes less and less probable for the observed acceleration associated with dark energy to be a real phenomenon rather than a correction factor added to fit the Friedman equations to a nonlinear varying metric which does not uniformly cancel out in all directions. The required binning of the sky to compute potentially different independent Hubble rates due to larger scale metric variability. While there are far too few galaxies studied for a Hubble rate beyond 2 sigma significance when accounting for this bias the evidence seems to suggest a highly anisotropic variability in the Hubble rate with much larger Hubble rate than the accepted supernovae Hubble rate towards the local void, and more interestingly a potentially smaller Hubble rate than that measured based off the CMB our towards the Laniakea supercluster members or the more distant Shapely supercluster indicating that the rate of expansion likely is decelerating. As optical measures of distance ladder measurements naturally exclude the zone of avoidance where the Milky Way blocks out optical light of more distant galaxies it seems increasingly probable that these combined factors can entirely account for the measured expansion rate as uncertainty in the allocation of kinematic, gravitational and cosmological redshifts can explain dark energy the Hubble crisis, the "axis of evil" of the CMB(as the measured CMB dipole is no longer kinematic but gravitational), the CMB cold spot, the "dark flow", the dozen or more impossibly large structures in the cosmos compared to the cosmological principal, really I can go on with the number of mysteries that potentially go away once the cosmological principal is dropped. Basically it suggests the gravitational field of Laniakea is dominant out to much larger distances than the cosmological principal allows which in turn is skewing observations as they assume that the universe is flat beyond 100 Mpc as our baseline. So any of the measurements will be off as the acceleration from the galaxy supercluster is getting assigned to the cosmological redshift rather than being interpreted as the non inertial effects of the local group being pulled towards the heart of Laniakea. As such galaxies in the opposite direction appear to be receding much faster away from us than the Hubble rate of the CMB would predict as the section of the sky where the Hubble rate is decreasing is predominantly excluded due to being obscured by our galaxy in optical wavelengths. However verification of this is dependent on the development of much more comprehensive galaxy surveys with the spectra of each individual galaxy cataloged rather than just a small subset (I.e. we need a sample size of a hundred million data points rather than a hundred thousand data points to reach 5 sigma significance) What is bizarre is that the error bars become sufficiently large that dark energy may or may not be needed yet it is still being assumed to still be there. I suspect this is a consequence of a Nobel Prize having already been awarded and the scientific community specifically cosmologists treading lightly around that as after all it means they would have to admit they did a bad job at data analysis and catching those mistakes in peer review. Scientists are after all humans and humans especially those with large egos don't like to admit they are wrong and the authority Nobel prizes give mean there is an outsized influence of certain people on the disciplines sub culture. I personally feel the EBOSS survey's results recovering the Hubble rate from the CMB once dropping the assumption of the cosmological principal was enough to show that the cosmological principal is the problem That said the potential existence of another force though isn't all that unexpected as there is some evidence suggesting dark matter does experience its own self interactions however so it should at least be considered if dark energy is being kept on the table. www.sdss.org/science/cosmology-results-from-eboss/ academic.oup.com/mnras/article/469/2/1924/3760286 www.aanda.org/articles/aa/pdf/2019/11/aa36373-19.pdf arxiv.org/abs/2007.04993

4:32. Ah, yes. The magnetic field space arachnid, or orbital orb weaver, crafting aurorae for millennia.

I came up with the same hypothesis (and several others) to explain universal expansion a few years ago. Nice to see one of them get some research done on it.

While vacuuming the carpets and dusting the floors I had an aha! moment and now know what dark matter is made of! It should have been obvious all along! Cat hair.

Dark matter might have reverse-gravity? Sounds a lot like scientists who don't know making wild guesses to me. But that is where a ton of science starts.

I thought we already explained dark matter and dark energy as the Flying Spaghetti Monster messing around. Ramen.

I've always wondered if just like a gas being released inside of a vaccum and expanding to fill it's container, maybe the universe is expanding for a similar reason. If whatever is outside of the universe has lower pressure than inside of the universe, it would expand without the need of dark energy. Even if that's the case though, it seems basically impossible to prove something like that.

Even with the resistance of those few particles though, gas expands incredibly fast when released inside of the vaccum but it does still have a limit to how fast it can go. If outside of the universe is a truly perfect vaccum without a single particle existing to decelerate the expansion of gas, I'm not sure whether or not it would ever quit accelerating because unlike a manmade vaccum, it's never going to fill it's container and reach equilibrium. But even if it does have a speed limit, maybe we just haven't reached it yet. Again, I have no idea what I'm talking about, but it's fun to wonder.

It may be switching apples for oranges, but if we already understand tangerines then its an improvement. (Terrible analogy, I'm sorry) Basically if the force behind dark energy is basically magnetism confined to dark matter, the we already have equations for that. Electric forces are mathematically identical to gravity (if mass could be negative and adjust the universal scaling constants). Magnetic forces are a result of moving charge, of dark energy is a result of moving dark matter with the same math then the only differences would be the scaling factor and possibly a limit to positive "mass" only creating purely repulsive magnetism. Before it was just: stuffs expanding so heres a force to do that, we know nothing else about the force.

The auroras... One point goes to the Thunderbolts Project for that. Reducing the number of unknowns (dark matter & energy) gives one point to mainstream scientists. I like where this is all going. 👍

I personally think this new explanation makes more sense than the idea that energy seeming comes from nowhere and thus requiring even more speculation to explain.

That hypothesis about dark energy also seems pretty nice because I can imagine that we can pin down the properties of the hypothetical dark matter particles that would fit their criteria. As in since we already have a decent idea of how much dark matter is unaccounted for and presumed to be mostly a new type of particle, scientists can test different strengths of this proposed force dark matter would interact with, as well as proposed masses of the particles themselves, to narrow down the specifics to whatever would lead to dark matter being capable of clumping together and holding galaxies together while also having a repulsive force strong enough to cause the acceleration between galaxies we see, and due to the fact that we wouldn’t expect galaxies to accelerate from each other 100% consistently due to differences in dark matter concentrations, looking for those differences could be an independent source of verification even if the proposed particles end up being too massive for us to realistically create. As such even if this theory turns out to be dead wrong, I expect that it will provoke a lot of discoveries that will help narrow down the properties of dark energy, and considering how much of this theory seems testable compared to some other dark energy theories we might be able to get an answer within years instead of decades, though that might be a bit optimistic. Exciting stuff!

I know a little bit about solar wind and planetary magnetic fields, but I had trouble following the Jupiter discussion because the graphics, especially the first one, were more confusing than enlightening with its plasmoids and sheet currents. Nowhere is Jupiter itself labeled, but "Io torus" is, which I did not understand. The animation of the reconnecting field lines was better.

The way I understand it is, Scientist call it dark matter & dark energy because they don't have a better understanding or a better name for it.

AIUI, the "dark" in dark matter is descriptive. Specifically, dark matter is dark because it doesn't interact with light (electromagnetic radiation). For dark energy, in the other hand, the "dark" was chosen, (again AIUI) because it was unknown and by analogy with dark matter. So, what you said is correct for dark energy, but not really quite right for dark matter.

Funny how some people denied dark matter and dark energy just because... they don't like those ideas. This is not how that work... (and I am talking about the comment, not the video. That's some good hypothesis) Anyways, I wonder if they are to solve that mystery during my life time...

If dark matter exerts a force previously unknown to us, won’t that imply a new type of force carrying particle? would this idea ultimately lead to a imbalance of dark energy, and hence different rate of universal expansion? Maybe even explain why the CMB have a gargantuan blue spot? How would the energies involved effect gravitation due to relativistic effects? Experiment idea: since we have a gravitational map of dark matter, and can probably use frame dragging to measure velocity.

So exciting

You should probably comment that this paper only considers whether this could explain cosmic acceleration (which sure it can... particles repelling each other tend to have that effect). But they don't comment on how this would affect galaxy formations, which DM is a very central part of and I imagine would be screwed up if dark matter started repelling each other as well.

Magnetic field lines on Jupiter: Oops I dropped something. BEEEEEEEEENNNDDD AND SNAP 👱‍♀️

Personally, I think the issue is more one of cosmologists ignoring the geometry and its inherent expansion, removing all the expansion (because it's "prettier" that way) by lumping it all into the variable a(t) and fudging the oordinates then asking why gravity alone doesn't account for it. Most of it is just there in the geometry before you even get around to adding mass. In Minkowski space-time (1,1-dimensional for simplicity) the observable universe exists as a flat line that crosses x=0 at the current coordinate age of the universe. That line only extends out to +/- 45 degrees before recessional velocity exceeds the speed of light. Now, what happens when you increase t? The line moves and gets longer since it still stops at the +/- 45 degree mark. Anything non-moving relative to the CMB basically stays at the same angle but the distance grows. That growth matches Hubble's law quite well but it's slowed a bit by gravity so you end up with a curve that falls below linear expansion with distance/time. The angle thing makes more sense if you swap coordinate and proper time to look at the problem in Euclidean space-time where it's half of an expanding circle and everything stationary with respect to the CMB is moving radially outward from t=0. Basically, though, time steps are multiplicative in rectangular coordinates and additive (just to the magnitude) in polar form.

The description of the new dark energy theory reminds me very much of Anne Elk's theory about dinosaurs.

About that theory of dark matter having a magnetic repulsion-like property to explain the observed expansion of the universe, it makes me think a little if it's maybe an elaborate astrophysicists' version of the "which came first, the hen or the egg" joke. Still, since any explained theory is better an unexplained one seeing as it lends itself better to setting up experiments to verify it, I guess it stands.

I proposed something similar in 2012. From the point of the big bang the space in front has no pull/push force but any matter moving outward from the initial start of our universe pull on one another giving our universe a constant expansion outward away from it's beginning. All objects pull on one another along with the Lagrange points to give a greater impact on other objects in space which should account for the lack of matter and IMO make cumulative gravity the greatest effect in our universe. Something mankind may understand if we survive long enough 🤔.

The cumulative effect pulling/pushing all objects away from the point of expansion makes perfect sense. The universe we live in is constantly expanding into a void and filling it with material.

"Dark energy " is timespace's expansion dragging everything as it flows by The gravity wells that hold everything together is cause by matter moving through TS . Matter's movement alone isn't enough, TS has to be flowing also. If TS was stationary stars would explode (not nova) all the time. When their rotation syncs up with their movement, as when a tire touches the road it is stationary no mater the speed of the car, The star would loose its gravity well and rip itself apart.

2.40 "This is an attractive idea..." No. It's a repellant idea. Let's go through this again until you understand it better! LMAO

Look up Gavin Wince's theory about time. Using 3 dimensional time equations he explains why galaxies rotate the way they do without the need for "dark matter" or "dark energy". On you tube the science is called "existics" and the episode is called " The Dark Side of Time". Enjoy!

Unfortunately fudging factors to explain rotation curves is insufficient to explain DM which is also inferred by many other observations in agreement that don’t support the alternative hypothesis. That is why MOND cannot explain DM also.

Dark Energy is easy to explain. I told this Idea my Physics Professor at UNI too: Dark energy is just the electro magnetic force between the WHIM ( Warm-Hot-Interstalar-Medium) Particles. These Particles are observed to be Ions which means that they repell each other. If at the stat of the Universe these particles were homogenously spread around they would repell each other more than they attract each other through gravity. If you do the simple math and compare newtons law of Gravity and the Coulombs law of the eletro magnetic force, both have the radius squared in the fraction. That means that as long as the charges and masses are fixed (which they are cause the WHIM is mostly made out of Hydrogen and Helion cores) the electro magnetic force is ALWAYS stronger than the Gravity of each and every particle. With this hypotethis you can also explain the current observable structures of the univers with its clusters and the fillaments between them. In regions where there were more unionised atoms after the big bang, Gravity dominated and formed the current structures over time. In regions with more ionised Atoms the Space just "expands" due to all the Particles pushing each other apart. My theory is yet to be completed and since i am a engineering student and not a true phycisist I might be wrong with some points, but since the power difference between the repelling of too protons compared to their attraction through gravity is around 1.2*10^36 it is clearly a obtion to look at. With that high of a power differents it is even explainable why there is more emptyness than filled space, because it is much more likely that the particles just repell each other and make the space "grow" than for them to bunch up and form clouds, nebula and later Galixies etc. Btw all of this is "copyrighted" knowledge, so dont sell it as your own idea if you ask someone about it. BUT please do ask Professors or other smart people about the possible of this idea beeing correct and credit me with the idea LOL.

The natural first (Occam’s) assumption to explain how or why a particle like a photon (or electron, etc) might behave as an uncertain location particle while also like a polarizable axial or helical wave “packet”, given that everything in the universe from electrons to solar systems are in orbit with something else pulling them into polarizable axial or helical apparent waves depending on the orientation of their orbits as they travel thru space, and given that we know we’re in a sea of undetectable dark matter but don’t know where it’s disbursed, is that they’re in orbit with an undetectable dark matter particle pulling them into polarizable axial or helical apparent waves as they travel where the speed of their orbit determines the wavelength and the diameter is the amplitude which would explain the double slit, uncertainty, etc. No?

Ideas like the planets all dance to the solar band & we are now looking at the sun over ourselves.

Dark Energy sounds like something from an RPG after all

Gotta love the geeks at NASA, they sent Juno to check on her husband (Jupiter) and his mistresses (Europa, Io, Ganymede, Callisto, et all)

" It's Like Physicists Finding Their Glasses They're Already Wearing " But i can see what it actually is

i always thought dark energy was because of virtual particles popping in and out of existence. when they pop in they create the space they occupy pushing the space around it out. when they pop out of existence they leave the space they created behind. so that creates a "pressure" to expand outwards. oh and thats y the expansion is speeding up. the more space available the more pops will occur.

@Questa Semplice Animazione So that would be a force with a linear relationship (just think about how the volume scales as you push to planets further apart (scales with distance), as you have the crossection of the planets times their separation being their spearated volume). So this behaviour could never imply a 1/r^2 force decay.

cross section of planets. And if you are talking about quantum pressure from gravitons it most certainly matters. Also you can not modify the wavelength relations without affecting energy and energy conservation relations.

@Questa Semplice Animazione You misunderstand the point. The force related to any Casimir type effect is directly related to the missing volume between your objects, which scales linearly with distance. There is no way for this to become a r^2 relationship. Certain materials can of course have resonances to certain wavelengths, but this is different. Also if you are talking about the blocking of some wavelengths like a Casimir type relationship you most definitely have pressure. Pressure is not a Newtonian concept, you find it in GR as well.

If dark energy doesn't exist, there would be a mathematical mystery of astronomical size.

2:38 "This is an attractive idea" Don't you mean a repulsive idea? ;)

Hi Hank! I hope you and everyone is doing okay!

Claims Dark Energy is debunked, proceeds to explain about a new speculative force similar to gravity. How is that debunking dark energy? It's just suggesting an explanation of what it is. It's not saying dark energy doesn't exist.

@@FitzgeraldStanburyWeissV my point is the other theory matches the definition of dark energy perfectly. It's not a debunking, it's an explanation.

Oh I do love scientific names like the Kelvin helmholtz instability. They crop up all over maths and physics.

Fast forward 100 years when hovercars use dark energy to float....

It is fairly simple, Dark matter is various "Black holes" from unfathomable universe sized behemoths to tiny brown/dark dwarf stars that exist everywhere, And Dark Energy is the Hawking's effect seen from the inside of a black hole.

Personal preference…vacuum superfluid theory explains dark energy better. In 2017 it was shown that you could define a surface-tension-like force in general relativity (under vacuum superfluid theory assumptions of space time) and if so, we have a mechanism which could exert opposing forces between two sufficiently distant massive objects, like galaxies. Imagine if space time could be modelled as a superfluid that could exhibit surface tension. Now imagine we have two galaxies placed next to each other. Within a certain distance and over sufficiently large time scales, the two galaxies will coalesce into one (attractive forces>repulsive Beyond a critical distance, they repel.

Have you guys done a video about the possible new physics results from Fermie Lab? Or did I miss it?

The greatest influence in Astronomy today is the attraction of scientists to provide guesswork to fill the vacuum of understanding that astronomical observations/facts are creating lol

The stars have been pumping out photons, neutrinos [and other stuff?] since they first formed, giving intergalactic space an "atmosphere". As the light from our own sun reddens as it passes through more of our atmosphere in the evenings, could the red shift in the light from distant stars be due to its passing through this "atmosphere" and not an indication of their recession? Could the universe be static? How many problems would vanish if that were the case?

One of the main issues with dark matter and dark energy is the math was done with bad calculations as we could not see a large amount of matter at the time due to the atmosphere. Everything in the Xray range and a few others that get filtered by the atmosphere was invisible to us throwing the numbers off and it will take years to look using the newer orbiting telescopes that can see the signs of what is there. So much has been found or confirmed since the math was done like black holes and super massive black holes have been seen since then that the smart thing to do is start over looking for what is there but then that is not what those making the research grants want to hear that everything is back to step one. We can't even tell is the Milky way and Andromeda are impacting already or if it is still millions of years from happening simply because of where we are watching from.

We can measure the light from a star and analyse the spectral absorptionto calculate how much mass is between the star and earth. We can never visually confirm all the dust that we know is there from spectral absorption calculations.

I mean it could always just be that dark energy and dark matter are the same thing. In Mass Effect they claimed that some of the neutronium (raw neutron slury) was both in that giving it positive electric currents could produce stronger are inverse gravitational forces and as such is both dark matter and dark energy. A repulsive force on the outside of the galaxies rim is just as effective as gravity itself caused by an invisible halo around galaxies. While eezo probably doesn't really work that way, it could always turn out antimatter has inverted gravitational force so assuming matter and antimatter survived the beginning of the universe they would never combine again forming galaxies that only attract to each other and not the opposite polarity. It would also explain why gravity is the only fundamental force that's only attractive and not repulsive. I still kinda doubt this is the case as we should still see gamarays between galaxies as small gas particles are less effected by gravity, but we can't completely rule it out just yet. There's also the idea of the GEODE, but that takes way too long to explain, look that up on Wikipedia instead. But back on topic, yes dark matter and dark energy might be the same thing, but that's definitely not guaranteed and I wouldn't push anything about it.

Indeed. It is healthy to admit when you are wrong.

This work is crucial to my sci fi novel! Lol

Dark matter is the black hole of physics as an actual science.

2021: The Year We Make Contact

Question: What if the expansion, or what we perceive as expansion, is just the pulling effect of the rest of the universe which is outside of the cosmic horizon? If the universe is still growing then it stands to reason that there is much more universe beyond what we can see, so the amount of matter beyond the cosmic horizon has more weight to it - therefore it is pulling on our little patch, which we can see, more than the net pulling effect of everything within our cosmic horizon. Does that make sense?

I talk with my hands, I talk with my hands ... furiously, furiously ... shakes head, shakes head ... wiggles back and forth ... talks louder, LOUDER ... oh yeah, science baby!

"This is an attractive idea" Talking about magnetic repulsion!

I did not understand a single thing talked about in this video, but it was somehow still very interesting.

Just some personal thought i had some while ago perhaps due to my lack of knowledge and misunderstanding these topics I sort of viewed dark energy and dark matter as something caused by virtual particles Virtual matter pairs pops into space then annihilates ye? And they cause the Casimir effect thingy Perhaps space expands because its pushed by virtual particles that pop in And as it expands it gives more space for virtual particles to pop thus the phenomena becomes stronger the larger the area of empty space stuff closer together become more strongly held together not because theres some dark matter there but because it the pressure of virtual particles push them closer? Maybe I’m completely mistaken i mean im not mathematician not phycisists But what do you fellas think? If its a dumb thought, i want to know why?

Good hypothesis. Seems like a possible explanation for DE. Probably too much of a homogeneous force to explain the variation in distribution of DM.

I couldn't help but wonder if the speed of light wasn't a constant, that might explain it?

Doesn’t io also constantly emit volcanic ejections into Jupiter’s magnetic field which then collects at the poles just like how it does with solar flares?

Is scishow seeing the light? :o

Could the speed up of the expansion be because we are still relatively close to the beginning of the universe? Like the explosion just happened (relatively) and it hasn't had a chance to have gravity start slowing it down?

So I have a question. Okay so they say the universe is expanding. Now is this solely from the redshift? If so then the opposite could also be true. Every thing closer to the center will be moving away from everything behind it and everything in front would be moving faster towards the center appearing to move away. So even if we were collapsing it would appear everything is moving away from us. Also it would appear to be speeding up because the closer to the center you get the faster you go.

I'm sticking to dark energy and dark matter until it's proven otherwise.
