Never quite understood the comments that say things like "misinformation" and "wrong". The reality is that our understanding of the universe is incomplete, so yes, what's being discussed here in its totality might not be entirely right. But over the last 50 years (actually much longer but I'm talking just what I have personally observed) we have slowly built a better and better understanding with some hypothesis not making the cut, or bits of a hypothesis being found true forming a new hypothesis. Essentially, we build our model bit by bit. I think it's clear, or to me it is at least, that we are on some right track just by how our technology and understanding in general is proceeding. In my own lifetime, the experimental process we have come up with has dramatically altered the world I live in.

yea i mean theres even stuff on this planet all we can do is theorize about. theres educated theories then like mind uneducated but i like them. like when a black hole forms its core is basically a big bang that creates a new universe so everything thats pulled in is whats expanding that new universe.... cause nothing can move faster than light... accept space expansion faster than the speed of light. then theres some nonsensical argument about well expansion isnt travel so its not breaking any rules... speed is speed imo. so just like this video.... stuff is pulling galazies toward the edge? or the big bang that created our universe is still pushing everything away from it so nothings getting pulled but rather pushed?

i always thought, that the observeable universe is nothing static, if you teleport 100 million lightyears away, the oberservable universe also shifts 100 million light years with you. is that wrong? If i am right, this mass actually should be in the observable universe of the masses that are affected by it.
The idea is sound, but hangs entirely on the teleport part, or a wormhole which is still more at home in science fiction. It kind of breaks our brains that a distance can be so far - and expanding - such that any matter and newly produced light will NEVER cross the gap, but the universe is so very large as to be effectively infinite, and compared to it, we might as well be quarks. We will never be able to move fast enough to catch up with the receding darkness in any direction, to really see what's past it.
@@MAGAWillSaveTheWorld "yes and no" would fit with ideas about an infinitely repeating 4D or toroidal universe, where the boundary is a loop and you just come back on the other side, like Pac-Man.

I’m not a scientist, but I really enjoyed a video I watched about the edge of the universe only being the edge because of light having a half life, and so at a certain point it decays. It was a fascinating idea. Have you ever come across it? I should try to find the video again. We love you!
No, the accelerating expansion of the universe makes so that there's a point from which the space there is moving away from us faster than light, so even light traveling straight at us will be moving away. Also before that point the light that has been traveling through a ever expanding space-time gets redshifted, which makes it dimmer and dimmer the farther it came from, it's not a decay but you could compare it to it, photons can't decay over time because they can't experience time at all for traveling at lightspeed
I'm not understanding. What is 'outside our Universe'? Simply outside our light-cone. So if that remote galaxy or cluster has that vast mass nearby which is outside our light cone, but within their's then it's likely THEY can still see it or be influenced by it, no? Oh, and your later graphic where all the stars stopped at the edge of our observable universe. What was that about? They'll go on and on, just not visible from here. Which kind of goes back to my first point.
I sometimes watch these videos and think about the shots of the cameras perspective flying through space and you see all the galaxies whizzing by I wonder how many times the speed of light the camera is actually moving lol
I saw a zoom out video a while back where they actually calculated the speed. It was in the millions of time the speed of light when hovering above the milky way if I remember correctly.
Funny how we default to imagining ourselves at the center of things. Maybe this strange attractor is actually increase density at the center of the big bang.
That's because this is our actual perspective. No matter where you are in the universe it looks like you are in the center. Imagine it beeing a "render distance limit" while everything moves away from each other. If you go into one direction things behind you disappear while new space gets visible in front of you. It still always looks like everything is uniformly moving away from you because space itself expands at any given position.
As I understand it, the edge of the observable universe is simply where light can no longer reach us due to the expansion of space from our perspective. I don’t find the notion of some massive object(s) beyond our sight still exerting influence to be that controversial. 🤔 Think of it sort of like a venn diagram where the Earth’s’ observable universe is one circle while the attractors gravitational influence is the other circle. While it may not have any effect on Earth, galaxies still within our sphere of observation could still be under its influence, yeah? (Especially with how old that light would be)
The force of gravity affects us with speed of light which means that even if our sun magically dissapears it will still attracy us and we will orbit it for 8 minutes , so this thing should not be able to attrack anything in a great distance arround us , so I think that is why this topic is "controversial"
Moreover it is thought that the edge of visibke universe is its end , if this attractor really exists it would be a scientific proof that a real universe has to be way bigger that what we see , which would contradict many of our great theorems and we would have to change a bit our timelines and statistics about early universe
I believe the big picture or a better understanding of what the universe is, is right in front of us and all around us. We just cant fathom or at all able to detect it, we just see what we see now. Kind of like a grasshopper in a field. Hes in a field next to a highway with cars next to the city. But he has no way of detecting or realizing it and never will. To me thats the special part ❤
Black Holes create Space by destroying matter, what is referenced as dark matter or dark energy is nothing more than dead matter. Universal expansion is caused by the simplest of things, the removal of gravity.. or as I call it magnetism. Without the ability to collapse matter, what is left is wild amounts of expansion. Black holes are amazing.
I had a thought along those lines relating to the repeating expansion and collapse of sequential universes. What if that mass out there is the extra-special omni-massive black hole at the end of this cycle? Never mind entropy...the reduction in speed that will eventually pull us back is just so gradual that it can't yet be detected with our instruments. It's out there, though, infinitely patient. Eventually, _everything_ goes back "home" to repeat the cycle. Or not repeat the cycle...we won't know, either way.

Astronomy and astrophysics are amazing fields filled with wonder. Answer one question and two more appear. But we need to keep an open mind and thus, keep theology out of the discussion.
The thing that puzzles me is the far away you look, earlier the universe you look. That means if we could see 13.5 billion years away (or whatever the age of the universe is) we would see the big bang happening all around the edge of the universe?
There wasnt any light that could travel that far back. The earliest light that could start to travel is the cosmic microwave background and thats what we already see
When these researchers and physicists do their number crunching, are they only taking gravity into effect, or do they throw electromagnetic forces in there too?
On large scales electromagnetic charges tend to cancel eachother. But gravity has nothing (that we know of) that cancels it out, so it just grows with size. Therefor, in most scenarios at big enough scales, all other forces but gravity is negliable. The exceptions of course being black holes and the big bang itself, which is why we really can't explain what is happening there.
Once upon the shattered plains drifting the scattering Void, there was a child of humanity. Born from an Echo in the Machine, we are infants in the emptiness, a Voidchild. Echoes in a Mind's Eye out January the thumbnail looks like the universe in my thinking noggin.
I fail to see how this is a problem. We have no idea how big the universe actually is, and this abnormally large mass might just be a grain of sand in the whole picture. We just need to look at it on a bigger scale. However I would really like a video with a thorough explanation of the inflation, and especially how they reached the factor 10^27. It seems arbitrary, and pretty small tbh.
Isn't the "observable universe" a local variable? A object outside of our "observable universe A" cant affect us but it can affect a nearby solar system because its "observable universe B" is shifted compare to ours?
Maybe The Universe as we know it is just the afterbirth of something much larger and stranger that has already moved beyond our view. Maybe dark gravity is pulling The Universe along after it albeit at a lower velocity. Then again, maybe not. 🤔
My personal *opinion* and I won't be persuaded otherwise lol. Is that our universe is just the interior of a parent universe's black hole. And that black holes within our universe may contain within them relatively smaller universes. All the energy seems to balance out properly in my mind this way. We could actually be 1000's of layers of black holes deep. I call it an infinite fractal multiverse
The cmb came from everywhere at once and went in every direction, so we’re seeing the cmb that was created in a different part of the universe and is just now reaching us
@@fatch3353 but the radiation from the other side of the universe would reach and go past us long ago, no? I am assuming the matter in the universe is expanding at much slower rate than the speed of light radiation is itself, also expanding.
@@Steve-Richter Everything traveling towards us is also slowed down because of the expansion itself, so I guess the cmb might be forever detectable and only reaching us slower and therefore weaker and weaker but never totally fading away until all other galaxies disappear behind the edge of the observable universe, indicating any remaining radiation that was moving towards us must have also been fallen behind that horizon. Then it I assume it will disappear. In short, as long as we can see those galaxies so far away, we could also be able to see the cmb, but it might change when these galaxies slowly disappear into darkness.
I don’t know because I’m not a scientist but is it possible there is a relationship between matter/anti-matter asymmetry or annihilation and these unknown sources of energy? My mind just wants to make a connection between missing matter and surplus energy but also I know the fields were different in the early universe so maybe that is relevant. I literally don’t know, just curious if someone smarter than me has any theories.
Maybe we are just stuff in the bloodstream of an infathomably large being and we are sensing something that is a heart valve sucking everything in. I am a big proponent of the whole infinitely large and infinitely small philosophy.
Neutrinos and light waves are travelling outwards, expanding the size of the universe at the speed of light, correct? But galaxies are travelling in the same direction but much slower? Meaning, the size of the universe much exceeds the outer edge of the expanding pool of galaxies?
It’s not neutrinos and/or light which expand the universe; spacetime expands on its own, and electromagnetic radiation and matter are simply carried along for the ride. Light travels at a constant speed _relative to the patch of space_ it is traveling through; but nothing prevents space itself from traveling away from another distant patch of space faster than the speed of light, which is how we see very distant galaxy clusters receding faster than light away from us. The fact that the most distant galaxies can eventually leave the boundary of our observable universe can be a bit mind-bending to figure out. I like the analogy of the universe being like pulled taffy, which has some lumps (the galaxy clusters) and very thin stretchy bits (the intergalactic void). Think of light like an ant crawling along the taffy as you stretch it (and lose your appetite), and you can easily imagine stretching the taffy faster than the ant can cross to one side.
I mean... the edge of the observable universe is just a matter of perspective. Yes, stuff just outside, let's say at 50 000 light years away from the edge can never affect _us_ but can still affect stuff 50 000 light years away from us in the direction of the same stuff. Maybe I'm underthinking it. ¯\_(ツ)_/¯
The edge of the visible universe is based on our position within the visible universe. Objects further away have a different "visible" universe. You do not need cosmic inflation to explain any drift just because it is beyond our visible universe as it would not be beyond that of the objects in motion if this drift exists. Or at least doesn't have to be, just beyond our vision isn't invisible to things on the edges of our vision. Might be one of the worst video's Astrum has done in that regards.
Is it accreting matter as it also moves outward? If so, it would produce gravity waves which themselves travel at the speed of light and would reach our location in the universe over time.
I've watched your videos with great enjoyment for years. Finally, I became a subscriber and can more easily see when you've dropped another one. Hmmm... sounds like a rabbit pellet. Nevermind. ps... I don't always agree with you but I do appreciate the effort and reasoning.
A vacuum can only exist within spacetime. The universe has no “outside” as you may conceive. Think of the end of a circle or the edge of a sphere, then try to extrapolate that to the side of a 4-dimensional hypersphere; of course that analogy is better suited to a closed universe and we still don’t know the actual shape of it.
About the cosmic redshift thingee; the miscalculation that cosmic redshift would predict a 'Dark Ages' was WRONG (fully formed spiral galaxies where there ought to have been nothing but primordial particles) seems to have had NO impact whatsoever on the bulk of cosmologists (nice work if you can get it). Despite direct observational evidence (James Webb Space Telescope), they STILL think nothing is wrong with their redshift interpretation. But one thing we know now: Cosmic redshift is NOT a reliable tool for determining an evolutionary past, and casts into doubt the entire expanding universe assumption.

What if we somehow got like a james webb telescope sort of devices to let's say neptune would that be able to see more since its distance its not a big jump for how much The james webb telescope can already see but just curious.
I doubt anything new would be revealed. The distance from earth to neptune may as well be a rounding error because of insignificant that distance is in the grand scheme of things.
A pushing force would basically be impossible. Gravity allows objects to be attracted, but the opposite of that would be the expansion of the universe but this happens from all parts of space. To be pushed towards something it would need to be a physical interaction between two objects

In short, as long as we can see those galaxies so far away, we could also be able to see the cmb, but it might change when these galaxies slowly disappear into darkness.
I don’t know because I’m not a scientist but is it possible there is a relationship between matter/anti-matter asymmetry or annihilation and these unknown sources of energy? My mind just wants to make a connection between missing matter and surplus energy but also I know the fields were different in the early universe so maybe that is relevant. I literally don’t know, just curious if someone smarter than me has any theories.
Maybe that is where all the anitmatter went? We are drawn towards it facing The Great Annihilation 😊
Maybe we are just stuff in the bloodstream of an infathomably large being and we are sensing something that is a heart valve sucking everything in. I am a big proponent of the whole infinitely large and infinitely small philosophy.
Maybe we are just the "smelly kid" of the universe and no one wants to be near us...
Is this related to the Great Attractor at all?
No, the GA (and the Shapely Supercluster) are much closer to us.
idk
Neutrinos and light waves are travelling outwards, expanding the size of the universe at the speed of light, correct? But galaxies are travelling in the same direction but much slower? Meaning, the size of the universe much exceeds the outer edge of the expanding pool of galaxies?
It’s not neutrinos and/or light which expand the universe; spacetime expands on its own, and electromagnetic radiation and matter are simply carried along for the ride. Light travels at a constant speed _relative to the patch of space_ it is traveling through; but nothing prevents space itself from traveling away from another distant patch of space faster than the speed of light, which is how we see very distant galaxy clusters receding faster than light away from us. The fact that the most distant galaxies can eventually leave the boundary of our observable universe can be a bit mind-bending to figure out.
I like the analogy of the universe being like pulled taffy, which has some lumps (the galaxy clusters) and very thin stretchy bits (the intergalactic void). Think of light like an ant crawling along the taffy as you stretch it (and lose your appetite), and you can easily imagine stretching the taffy faster than the ant can cross to one side.
Yeah!!!!
All we have to do is build a warp drive. Problem solved.
I mean... the edge of the observable universe is just a matter of perspective. Yes, stuff just outside, let's say at 50 000 light years away from the edge can never affect _us_ but can still affect stuff 50 000 light years away from us in the direction of the same stuff. Maybe I'm underthinking it. ¯\_(ツ)_/¯
Guth is pronounced similar to tooth.
EZ. Our birth was banged from a white hole, and our death is sucked toward a black hole. Rinse, repeat. Circle of life.💸
Diffusion?
Tops !!!
@5:18 - at or beyond the edge of our OBSERVABLE universe…I think is what you meant
Is the CMB data really reliable enough to use it as a base to for this idea?
The edge of the visible universe is based on our position within the visible universe. Objects further away have a different "visible" universe. You do not need cosmic inflation to explain any drift just because it is beyond our visible universe as it would not be beyond that of the objects in motion if this drift exists. Or at least doesn't have to be, just beyond our vision isn't invisible to things on the edges of our vision.
Might be one of the worst video's Astrum has done in that regards.
yay! new video!
I love TH-cam and if you watch in the brayeve bowrser, you not will see addds any.
Gravity.
If its invisible then its a black hole is it not?
Is it accreting matter as it also moves outward? If so, it would produce gravity waves which themselves travel at the speed of light and would reach our location in the universe over time.
Azathoth O.O
😐 why.
I've watched your videos with great enjoyment for years. Finally, I became a subscriber and can more easily see when you've dropped another one. Hmmm... sounds like a rabbit pellet. Nevermind. ps... I don't always agree with you but I do appreciate the effort and reasoning.
If outside the universe is a vacuum then we will expand into it. Quite simple. Forget about dark matter etc,
A vacuum can only exist within spacetime. The universe has no “outside” as you may conceive. Think of the end of a circle or the edge of a sphere, then try to extrapolate that to the side of a 4-dimensional hypersphere; of course that analogy is better suited to a closed universe and we still don’t know the actual shape of it.
Craaazy, thinking about the edge of the universe.
yes, what exists at the outer edge of the universe? Will there be stars and planets?
Then it just turns out to simply be the epicenter of a cluster and nothing more.
About the cosmic redshift thingee; the miscalculation that cosmic redshift would predict a 'Dark Ages' was WRONG (fully formed spiral galaxies where there ought to have been nothing but primordial particles) seems to have had NO impact whatsoever on the bulk of cosmologists (nice work if you can get it).
Despite direct observational evidence (James Webb Space Telescope), they STILL think nothing is wrong with their redshift interpretation.
But one thing we know now: Cosmic redshift is NOT a reliable tool for determining an evolutionary past, and casts into doubt the entire expanding universe assumption.
What the hell is this comment section????
Just youtube allowing spam bots to run rampant through the comment section while simultaneously telling us we can't use ad blockers.
@@iambiggusAnd allowing all their comments to go through but something completely innocuous you say somehow trips TH-cam's censorship bots and deletes your comment without explaining what offended its sensibilities.

@@TheForeignGamer It really is ridiculous. I once couldn't post a comment until I removed the word "nuclear". On a physics video!

We gotta find some new terms for things we don't understand besides calling it "dark"
Kashlinsky needs kaopectate. To stop the dark flow.
I haven't watched yet, but that's a cool ass thumbnail.
I've actually had the bad fortune to run into Dark Flo. Stay away. Stay very away.
last time i was this early matter was still just a theory...
What if we somehow got like a james webb telescope sort of devices to let's say neptune would that be able to see more since its distance its not a big jump for how much The james webb telescope can already see but just curious.
I doubt anything new would be revealed. The distance from earth to neptune may as well be a rounding error because of insignificant that distance is in the grand scheme of things.
So...dark energy, dark matter, and now dark flow?
Its your mother
Nothing.... Nothing is doing that.
Something tells me that these people have no idea what they are saying
No proof given.
They just spew random words that miraculously create sentences?
why does it have to be something pulling it? can it not be something that has pushed (explostion) these object away in that direction?
A pushing force would basically be impossible. Gravity allows objects to be attracted, but the opposite of that would be the expansion of the universe but this happens from all parts of space. To be pushed towards something it would need to be a physical interaction between two objects
Not in the 39th dimension with a retroplanc glark shift of below 25.7 narcelflerts per scunge factor. Simples!
Science is constantly disproving itself.
We have been lacking a ground breaking discovery(astronomy, physics, cosmology)of some substance for decades.
We have a 20% understanding of reality
“Expansion” theory is a lazy way to make the math work. It’s literally a religion.
It's really fkd up that we say we can't understand the model of an infinite universe,but the model is a linear funnel... When it actually goes in every direction 360° why is the model only directed in one direction...until we accept and understand that macro and micro , quantum physics is more confusing than the macro, everything is possible on every level.. especially the " impossible" ....some of us,but not all have the ability to understand the energy that can't be quantified by our manmade written laws...,our conscience holds the answers both without and within..., it's all the same... open your minds
I have no idea how you manage to sound like an AI hallucination with extremely bad English and a randomized word lottery at the same time.
Plot twist it's a larger sexier universe just outside our observable range.😅
The edge of the observable universe is just another way of saying that we have not invented a telescope larger than JWST yet
The event horizon of the black hole we are inside.
There have been people who have suggested this, but it has no observable evidence. There are real anomalies that would be detectable if we were in an enormous BH. None of those anomalies are present, not even in a tiny way.
@ really? Because I’m old enough to remember when they said the Milky Way galaxy was the entire thing?
@@someguy-k2h consider this. Every atom is a universe. As above so below
@@BradyHansen81 That's what every 7 year old thinks the first time they see the Bohr model of an atom, and the Copernican model of the solar system. Then they have the same thought again after toking up for the first time. It's quite a banal thought.
