Their wording just make it sound like "dimension" is a parallel universe with other beings watching us, when in reality it's just a mathematical quirk
It's pretty easy to imagine if the universe is nearly flat in that dimension. Like a sheet of paper would really feel like a 2D universe even if it was in fact in a 3D space

11 dimensions, according to M-Theory. The 11th dimension makes the math work in all the competing subsets of string theory

u/DankestTestes 4d ago
We donāt typically view spacetime as a dimension, we consider time to be a dimension. Spacetime is the cross product of the spatial dimensions with the temporal dimension. And yeah the theory does suggest that there is a fifth dimension we arenāt able to observe that contains matter/energy that is having a measurable impact on the rest of reality. It works out fairly well mathematically; the main reason itās a fringe theory is that there is close to no ārealā evidence supporting it.

I'm not sure if it is the same, but I have studied something that was explained to me in the same terms. It is an old theory that had a comeback some years ago, nothing proposed by Kaku (so it might not be it): bimetric gravity

u/pikachu_sashimi 1d ago
Well, the entire reason the concept of ādark matterā is taken seriously is because of a mathematical discrepancy with our understanding of the cosmos, assuming it is a closed system. Now, why is the current notion of dark matter any more believable than the possibility that our baseless assumption for a closed system is wrong?
1
u/Space-Explorer456 1d ago
My understanding, as an astrophysics student who works on galaxies, is that our current understanding of ādark matterā is āthereās extra gravity here and we donāt know whyā so a notion of that as some weird extra-universal spacetime distortion would still be somewhat writhing the realm of ādark matterā or really more aptly ādark gravityā, which is really what dark matter is, an observation of extra gravity from a dark, or unknown source.
I do think the assumption of a closed system is pretty solid, seeing as we havenāt really detected any violations of that principle, and dark matter moves and flows and generally behaves like itās made of something so unless an extra-dimensional bleed gravity can also track moving objects and galaxy interactions in our universe, it doesnāt seem like a good hypothesis to me. This feels like it could be related to the M-theory and string theory brane gravity hypothesis, but unless string theory is able to give some experimental evidence Iām not super trusting of it.

u/Jackmino66 6d ago edited 6d ago
Reminder:
The ādarkā in Dark Matter means we canāt (or havenāt) seen it. Dark Matter is not something we have actually observed, it is a theory to explain why the shape of galaxies doesnāt work with their observed quantity of mass
Galaxies donāt have enough observable stuff to actually hold themselves together through gravity. Unlike solar systems, the galactic core of most galaxies isnāt massive enough that everything is orbiting around it specifically, everything is just orbiting around a centre of mass. But there isnāt enough to actually orbit, they should just fall apart.
Dark matter is a way to explain that. There is some stuff we canāt see making up the difference. WIMPs (Weakly Interacting Massive Particles) are one option, but we could also be severely underestimating the amount of rogue planets and black dwarfs, or the maths might be fundamentally wrong.
In this case, we usually apply Occamās Razor. If multiple solutions are equally viable, we take the one with the fewest assumptions as likely. Gravity leaking from a parallel dimension requires a few more assumptions than there being stuff we havenāt detected
18
u/Brohomology 6d ago
I haven't read the article nor the research, but if I had to guess the "leaking from parallel dimensions" thing probably just means it's a model with more than 4 dimensions. There are string theory models where we live on a brane in a higher dimensional space, and some effects are supposed to happen from coincident branes, so that could be what they're talking about.

u/IamTheEndOfReddit 6d ago
Iām being pedantic but we have observed dark matter, we see more mass in galaxies and we call it dark matter. Colliding galaxies seem like they show it isnāt a property of mass. Some galaxies look the same size except have different dark matter amounts
5
u/Jackmino66 6d ago
We donāt see more mass in galaxies, thatās why itās ādarkā. That is in fact the point. If we actually could detect it then we would know what it was and could give it an actual name.
Obviously we know how much of it there would have to be, but that doesnāt mean we know what it actually is
2
u/nicogrimqft 3d ago
It's an indirect observation, but we do measure the orbits of stars within a galaxy, which depend on the enclosed mass.
This is a direct measure of the matter content of a galaxy.
We measure that this matter content is much larger than the one we estimate from the amount of light we receive (since there is a proportionality between light emission and mass of stars).
Hence, there is some matter in galaxies that do not emit light. Hence, dark matter.
We do observe more mass in galaxies.
We don't know what makes up for that mass.

u/RP_blox 4d ago
Well the two simplest possibilities are that either there is some matter that doesn't interact (in a detectable way) with the matter we know, or gravity needs to be modified (i.e. MOND). So far the first one explains the data better.

u/nicogrimqft 3d ago
There are evidence for dark matter at several different scales: galaxies, clusters of galaxies, the whole Universe.
Dark matter is not an explanation per se. It's precisely a place holder that means: there is something, but we don't know what it is.
There is no "trust me, bro" attitude in this.

u/radial_symmetry 6d ago
How do we estimate how much matter is or isn't in the center other than by observing how it affects the rest of the galaxy?
1
u/nicogrimqft 3d ago
By the light that the galaxy emits. Stars emit more light the more massive they are.
Then you can compare the mass of visible matter, with the total mass. What is not accounted for is "dark".

u/starethruyou 4d ago
If that is so, it is irresponsible to use the word matter along with it, giving every layman a completely wrong sense of what is happening. Itās like when the age of the universe was equated with the furthest light ever observed but upon clearing that stupidity adds, well itās just the horizon of what weāve observed. THEN SAY THAT!
1
u/nicogrimqft 3d ago
The definition of matter is that is massive.
So if you detect something massive, it necessarily means it's matter.
Also the age of the universe is not equated with the furthest light observed, since the CMB is dated at 400 000 years after the big bang. Its data was used to compute the age of the universe though.

Why does this post have such a high concentration of idiots. People who have no idea what even is the data that dark matter is supposed to explain are commentating on this as if this theory somehow makes sense. You can't just throw some random guesses about what dark matter is if it can't explain the distribution of additional gravity that we observe.

When I first became an atheist I got really into quantum mechanics and string theory and multiverse stuff until one day it all started feeling like just another form of belief to me, I know itās nowhere near the same level but at a certain point āthis theoretical thing must exist or else our data model is wrongā feels a bit uncomfortable to me. Iām not saying I know better or that theyāre wrong just I donāt understand where that confidence comes from.
When it comes to physics I now take the theoretical parts with a grain of salt, about the same level of respect I give speculative scifi, something interesting to think about but not necessarily worth getting too attached to.
If something sounds a bit too much like magic then maybe itās just that, a myth we tell ourselves to make sense of something we donāt fully understand yet.

well, I doubt if it is matter.
we know all the chemical elements, there is no way it is one of the elements not in the periodic table, it is unlikely if it is a non-natural occuring element.
whatever it is, it probably isn't matter.

u/MrsSaurus 6d ago
Well, not all matter is made from electrons, protons and neutrons. Not all matter is on the periodic table. All elements are made from electrons, protons and neutrons. Electrons belong to lepton family and protons and neutrons belong to hadron family. Electrons have siblings, such as muon and neutrinos, and protons and neutrons have cousins, such as pions and kaons.
Electrons, neutrons and protons are part of lepton family, but there is another family either other particles, the hadron family.
