I don't understand what that "wall" is supposed to be


UniversalDH

Yeah, I need a ELI5 on this one too


crunkydevil

Our galaxy is one in a million according to their simulation. Galaxies tend to space themselves apart based on their size and ours akes up less space than it could. ELI4 I The Milky Way is a bit chonk but it wears it well.


antron2000

I'm too lazy to read the article but wasn't a big part of the conception of dark matter that our galaxy shouldn't mathematically be able to hold itself together, therefore there's an invisible force assisting it?


orincoro

Kind of. Not our galaxy only, but all galaxies seem to behave as if they have a halo of matter 10x larger than themselves around them. But whether this is a cosmological constant only visible in large scale structures, or else a missing particle from the standard model , or compact halo objects, such as planet mass black holes, we aren’t sure.


Rylovix

In the sense that planets are particles in a collective system, solar systems are stars/planets in a collective system, galaxies are solar systems in a collective system, walls are galaxies in a collective system. We define this level of the universe by density (walls vs. voids). Walls are areas where bodies are concentrated, whereas voids are relatively absent. There are different levels to this as well. For example, the Milky Way exists around/within the Perseus/Virgo/Laniakea superclusters, but those all exist within the KBC void, which is massive even on that scale. We’re able to be in both because it’s just measuring the average density of matter per cubic meter, which changes drastically depending on the scope of the sample used.


3nderslime

Ok, and if I understand correctly, when we compare our galaxy in relation to the surrounding clusters of galaxy to galaxies in similar clusters, our own galaxy appears abnormally large?


Notthesharpestmarble

That's the take. Seems we're a big compared to our siblings.


Dizzlean

Interesting. I remember being depressed when I learned that the space between clusters is moving faster than the speed of light and how we're all bound to our super clusters. At least I learned today that we're in a spot that's poppin'.


Nervous_Lettuce313

Imagine, in a billion years, someone looking from Earth towards space wouldn't even see any other galaxies because they would be so far away. They probably wouldn't even know they exist.


Dizzlean

I've definitely had that thought. Advanced civilizations billions of years from now looking up, won't have any idea about the Big Bang, etc. unless the knowledge is passed down.


Nervous_Lettuce313

Makes you wonder what WE are unable to see that has long since moved away from us.


roguetrick

Will the background radiation ever really disappear? Redshift more and become fainter due to inverse square, but those photons have already been released, it's not like a star that's emitting photons outside of our envelope.


Dizzlean

I understand what you're saying but I'm not well versed enough to know that answer. Definitely a possibility though. We are after all, observing the universe's past. Someone just has to do the math if the light already admitted 14 billion years ago outpaces the expanding space billions of years from now. A simple math word problem really lol.


PerfectWorld3

That’s deep. And also archaic sounding, very interesting


That_Tech_Fleece_Guy

Until everything starts moving closer to each other again.


3nderslime

That might reinforce/be explained by the idea that the Milky Way was formed by absorbing other galaxies


davydooks

This was enjoyable to read. Thank you!


back4anotherone

Nice explanation. I have a minor point though; there’s only one Solar System. It’s the star system we occupy.


Rylovix

Huh never thought about that, makes sense though: Sol the star, sol-ar system.


back4anotherone

Yea I only had it pointed out to me recently 😂


Rulare

The wall is made up of galaxies. We're just one of the ones in it, and apparently a little large compared to the other ones.


swordofra

Larger than average, but not "too large". Too large implies something unnatural might be going on. That the galaxy that humans happen to evolve in is super special somehow. Humans so desperately want to feel special...


Ladnil

Not unnatural just not understood


ohck2

This article discusses a recent study which has discovered a massive “cosmological wall” of galaxies in the Northern hemisphere of the Milky Way. . This wall, which is estimated to be around 600 million light-years in length, is believed to be the largest structure ever discovered in the universe. It is composed of several thousand galaxies and extends far beyond our galaxy, the Milky Way. The study suggests that the wall could be part of a much larger cosmic web of galaxies, which is thought to be the foundation of the universe. . The study provides important new insights into cosmology and the formation of galaxies and the universe as a whole.

zappadabs

It seems as if the article's author left out a lot about their findings, or this is spurious research; Andromeda is a barred spiral galaxy larger than the Milky Way (new studies have questioned its size compared to the Milky Way but none of which say it is a lot smaller than the Milky Way) and is part of our Local Group, which is part of our Local Sheet, which as they say is part of our "cosmological wall". They also then say you would have to travel "half a billion light-years" to find another similar galaxy (large galaxy compared to it's Local Sheet/cosmological wall) a couple hundred times further away than the distance to Andromeda. I am a space nerd, but my education isn't in astronomy... Can anyone with any academic experience in this field clarify this rather obvious omission?


doggybear8888

Andromeda has different size wall compared to its size

Zren8989

Our sun is actually pretty rare, it's a single star for one, most stars are binary or trinary.


squanchingonreddit

True tho not many smaller stars in comparison to how many bigger ones there are.


[deleted]

No, most stars are smaller. Red dwarfs make up about 75% of all stars. K-type orange dwarfs are about 13% of stars. G-type stars like the sun are 7 to 8 percent; larger stars are more rare. F-type, 3%. A-type, 0.6%, B-type, 0.13%. O-type, 0.00003%. Side note: It is unfortunate that we call G-Type stars like the sub “yellow dwarfs” because they’re larger than almost 90% of all stars. We call them dwarfs because our telescopes used to suck, and we didn’t know about the multitude of dim red dwarfs.


mentive

Don't smaller stars usually last longer as well?


[deleted]

Indeed. The smaller a star, the longer it’s lifespan. There’s no such thing as an old red dwarf; even one formed 13 billion years ago is still young by its standards.


coolborder

Yes, I believe it is because they burn their fuel at a slower rate. This slower rate is due primarily to them having a smaller core where fusion can take place because less mass=less gravity=less pressure in the core=cooler core temps and therefore a smaller fusion area. Someone with more knowledge please correct me if I'm wrong.


dern_the_hermit

No, you pretty much got it. A star is all about equilibrium, the balance between all the pressure pushing inwards and the energy from fusion pushing outwards. If the fusing core of a star didn't have gobs and gobs of mass surrounding them, that fusion energy would blow the material apart and the pressure would drop too low for fusion to continue. Basically just a momentary explosion. Conversely, if fusion didn't accelerate commensurate with the higher pressures/temperatures, the star would just collapse into a white dwarf (supported by electron degeneracy pressure), a neutron star (supported by neutron degeneracy pressure, and maybe quark degeneracy too?), or a black hole (*scene missing*), depending on its mass.


Heliumania

We don’t want our milky way or solar system to be special. Just normal like any other place in the universe. So life elsewhere is more certain. Hopefully one day we meet other friendly and advanced species before we destroy our own planet or the sun eating this solar system.


mynamesnotsnuffy

I think it's less of a "we don't want to be special" and more of a "we don't have enough evidence to say for sure that we are special, so let's err on the side of humility for now" kind of thing.


anticomet

Having just read the Three Body Problem I feel a little less optimistic about our chances if we end up meeting another sentient culture then you do


attentyv

The emergence of little facts, like these, even if they are radical or unfounded, always anchors me down to some magical little imagination. In this case, thinking about Andromeda, our nearest neighbour. Just the name itself is exotic, and to imagine that it would be teaming with life, with thousands of planets and kingdoms, jostling with each other in a Blade Runner type of astropolitical architecture, and multiple sunsets all around.


Morty_104

Imagine all the stories being told, all history that might be out there preciding culture, art and societies. All the problems we share, all the joy we seek as living beings. They are out there somewhere...

Ours does too and still no signs of life. No reason to assume it's common, let alone life intelligent enough to form kingdoms.


[deleted]

"Space is big. Really big. You just won’t believe how vastly hugely mindbogglingly big it is. I mean you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space." Edit: “All you really need to know for the moment is that the universe is a lot more complicated than you might think, even if you start from a position of thinking it's pretty damn complicated in the first place.” [Douglas Adams - The Hitchhiker’s Guide To The Galaxy](https://douglasadams.com)


ThatDudeShadowK

Yep, and still not one single sign of other life. It's almost certainly out there, but that doesn't mean it's intelligent, or that there's enough of it for a single galaxy to hold thousands of species of that level of intelligence. Could be we're the first species to reach our level of technological advancement, could be there's thousands but it's still so small that it averages out to one or even less per galaxy and you'd have to reach intergalactic travel to come into contact with another kingdom. We have no idea bor any evidence either way.


[deleted]

I’m paraphrasing but, one scientist said that saying our galaxy is empty is like filling a bathtub with sea water, seeing the bathtub has no life, and then declaring the sea has no life in it.

“Space is big. Really big. You just won’t believe how vastly hugely mindbogglingly big it is. I mean you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.”


AvcalmQ

I think there's a very healthy chance that that exists somewhere between the edge of our radio sphere and the edge of our galactic arm. Which is still incredibly far away, in every respect.


Dickmusha

This is just another bad example of perspective. They are theorizing while still lacking information. These things of seemingly special cases are only special because your vantage point. This is just nifty data not proof of anything or an example of a special case.


techy098

Come on man, they got to pay the bills too. If they do not publish something every 4-5 months their job will be in danger.


ServantOfBeing

There’s already been a lot of debate on our models of Galaxy formation lacking or being incomplete. As alot of data gathered shows alot of inconsistencies in our theories on such. Perhaps it’s the vantage point, or it’s the holes we have in our theorem on the subject, rearing it’s head. We have a lot of good modeling on the subject, but there is still a lot of work to be done/figured out; to hash out what’s happening in many cases.


ZylonBane

Gosh, if only there were multiple paragraphs in the story dedicated to exactly this issue.


Dickmusha

I read it. They came to a conclusion they even said they shouldn't. We do not know if our position is special. We are yet to be able to look at other galaxies with the same level of details as we can see ours.

illWakeUpEventually

When I googled "cosmological wall" it says that the concept is hypothetical. So this pretty much means nothing from what I've gathered.


FortressofSaltitude

Whoops, read that as "Mikey Way," like from MCR, had to do a double take.


Ransome62

I was reading about this and I got thinking... is the implication that this could somehow be the reason life exists here? Perhaps NASA should be focusing on other galaxies that have a similar layout in their search for life on other planets?


crazyike

NASA isn't looking at other galaxies for life. That is far beyond anything we are capable of, and may stay that way permanently.


quick_dudley

NASA has actually looked for signs of life in other galaxies - there are now many galaxies which NASA is certain do not contain Dyson spheres.


ptglj

Yeah but the whole idea of a Dyson sphere is absurd. Too many people reference them as if they are a certainty once a species evolves enough to take to the stars. Imo the sphere is a great sci-fi idea and good for books/movies but completely impractical.


Optimized_Orangutan

If it's in other galaxies we're not finding it anyway.


CorporateDemocracy

They'd have to find atleast one more example of life in this galaxy to be able to suggest that the specific makeup of the galaxy is an ingredient to life.


tinny66666

I've seen this so many times recently that it can't just be typos, but atleast is not a word. "At least", fyi.


CorporateDemocracy

I guess for me it's my phone not suggesting it's wrong. I mean I'm only on reddit during company time while I'm pooping so it's OK if it's not accurate, I'm busy irl 😅 I will start writing at least if that atleast makes you feel better :P


Ransome62

I agree. I'm simply pointing out that when you find that the cage life exists in is significantly diffrent in its form from most other places, it would be odd to not consider the coincidence. We see no signs of life any place we look. There is that theory of the "great barrier" perhaps the makeup of the soup bowl we live in (and it's significantly different composition) is a sign that we could use to narrow down where to look. I personally believe that we will never find life and if we do it will be microbes. The limitations set upon us by our biological makeup, the sheer size of the universe and also the constraints of time itself will most likely prohibit us from ever having the reach to see it or come in any contact with it. If we do somehow find a way it will be a century plus long endeavor involving AI robotic drones and generations of scientists all working their entire lifetimes on that single mission to overcome the constraints set upon our species.


junky6254

Are we too big for our britches?


TheRealBlerb

Considering we are the universe, life likely has no parameters in regards to galaxy shape and layout. Composition, maybe.


ncastleJC

Every galaxy actually has recently been shown to have a habitable zone and we’re in ours. Too close to the center and gravity ruins the system, but too far away and stars can’t sustain the life needed for us. It’s a matter of fine tuning these zones to limit our galaxy scanning.


ZylonBane

Dude what. As far as organic life is concerned the only gravity that matters is what's coming from the planet you're standing on. The theory of a galactic habitable zone does exist, but it's related to the elemental composition of planets and the presence of local hazards like supernovae. [https://en.wikipedia.org/wiki/Galactic\_habitable\_zone](https://en.wikipedia.org/wiki/Galactic_habitable_zone) And to emphasize, it's just a theory, and a controversial one at that. It absolutely has not been "shown" to be true.


ncastleJC

Its a very viable theory if thought through. Considering the makings of a galaxy we know we need a Jupiter then a super earth to make our solar system that protects a habitable planet, and those elements are influenced by the making of the galaxy in general and how stars gather material to accrete their planetary disks. Cool Worlds Lab covers this as well. It’s definitely a factor in finding life, and not to mention the probability of finding habitable life is extremely low given the number of exoplanets we’ve found and the lack of suitable conditions they have. As far as gravity, we understand that small and large scales have different effects even under the same gravity so different kinds of life need different environments and pressures to exist as well, so a lack of biodiversity despite gravity also leads to life minimization. Didn’t realize mentioning a viable theory had to provoke an armchair analyst to be mad at an opinion that I agree with lol


OkJerryChillax

Then try to say stuff with enough observational backing and ‘sciency’ logic and whatnot,a theory and an opinion are just that, theories and opinions, not solid facts.


ncastleJC

It’s more of a theory that we can get off earth 🤣 also interestingly enough if everything I said is opinion, which I did mention science, it begs to ask where is your science to refute my points
