James Webb Telescope Just Revealed the True Scale Of The Universe!
Embed
- Published on Feb 12, 2026
- The James Webb Space Telescope has changed how we understand the universe - not just by seeing farther, but by revealing how much larger reality truly is.
In this video, we explore how Webb uncovered galaxies forming just 300 million years after the Big Bang, why the observable universe stretches 93 billion light-years across, and how cosmic expansion hides vast regions of space forever beyond our reach. What Webb found challenges long-standing models of galaxy formation, exposes the invisible forces shaping cosmic structure, and raises profound questions about what exists beyond the limits of observation.
From the nature of light and time, to dark matter, dark energy, and the cosmic horizon itself, this cinematic deep-dive reveals why the universe is far bigger, more crowded, and more mysterious than we ever imagined.
This is the universe - as James Webb is showing it to us.

On sleepless nights, becoming aware of the vastness of the universe can help the mind feel less constrained.
The statement treats "feeling less constrained" as straightforwardly desirable, but constraint sometimes serves a function. The boundaries of ordinary perception anchor us.
its just so sleepless sometimes
It gives me panic attacks. Literally feels like an elephant sitting on my chest..😂
Lets me know God is much bigger than my current estimation of Him, and that size may not be as important as I think it is.
@SanchoGraciecan’t tell you how to feel but it gives me a sense of relief. We are so insignificant that it makes me feel free. Enjoy this small sliver of time that we are able to experience.
A photon traveled nearly the entire life of the universe only to land on James Webb Telescope. That is wild.
Yeah - but for the photon that flight happened instantly.
@nightworg🤯
photons do not travel their light is a transfer of enrgy......flip a switch to a table lamp.........is allowing energy to transfer through the atoms of the copper wire ....there is no "flow".................only energy transfe...........!
@thomas-gw3xfWhat is it flowing through in space for billions of years?
@t@thomas-gw3xfyou may be thinking of electrons
Perhaps there is no end to the Universe.
We on earth truly are nothing, hardly a grain of sand on a beach.
Considering this where does that leave the religions on this blue ball, politics on this ball. All of it is truely nothing
Imagine the Earth is the size of the smallest grain of sand you can get then imagine that grain of sand having to travel 37million km just to cross the Milky Way.
Not even that big.
I'm not real clear on your math. One light year is 9.46 trillion km making 37 million km just a small fraction of a light year.
@rawhideadventures9515 If you scale the Earth to the size of a grain of sand and think of the Milky Way being about 74 trillion times wider than Earth, it’s like a grain of sand vs 37 million km. I initially thought of 0.05mm for the smallest but I see I used 0.5mm for this scale.
Mellow, soothing, and fascinating. Quite the lullaby.
It’s remarkable how long it took for cosmology to fully embrace the idea that there might be no clear boundary between “the universe” and “nothingness!”
In many modern theories-such as eternal inflation or the Hartle-Hawking no-boundary proposal-the Big Bang isn’t a dramatic emergence from absolute void or a true beginning. Instead, it may simply be a local event: a phase transition or “bubble” of expanding space-time within a vastly larger, eternally infinite universe.
What we perceive as the grand origin of everything could, in reality, be just a minor, commonplace fluctuation-one local phenomenon among countless others.
There's no such a thing in Nature as an "infinity" its a construct, just like zero. You can't count zero of a thing. I'll try to explain: not only is that count qualitatively contradictory, but the quantitative nature of "nothing" occurs only by the absence of a categorical existence which - by definition - ennunerates it. Infinity cannot be ennunerated by direct observation, cannot be compared against a knowable standard of measurement that is empirical and observed in Nature. It is a regrettably meaningless interval of interminable scale. The universe is scalable, knowable and ultimately real.
@santyclause8034 How many billions do I have? 😂 ZERO. BUT, I get your point, and you are correct. In the wider scheme, there is nothing that is zero everywhere. And likely, infinity is the same, because of it's relation to the concept of being non-scalable opposites.
Our observable universe is like standing in the middle of an ocean and saying this is all there is.
well put
More like... being a fish in a pond and saying "this is everything"
I love how the video sparks curiosity and encourages deeper thinking about the universe.
Thanks😊
Thanks chatgpt
I always find it hysterical when something in the universe defys the laws of arrogant human physics. 😅
They try soooooo hard to avoid the fact that something cannot come from nothing. The "big bang" came from what? Maybe it was created by an intelligent eternal Being? That being must be more intelligent, bigger, & more powerful than the Universe itself! Think about that? We are like tiny ants. Tireless but limited, bound in space, location, & time. We cannot possibly understand!
@cherylfox6765yes God and he visited us in a body,his son jesus to give us a door out before it is destroyed
@arfermo853and then came trump, undoing so much of what Jesus worked for.
@patrickryan8869ALL things work toward the good for those called according purposes. Thing look bad at time but later you look back and say ,wow
@cherylfox6765from where the intelligent eternal being come from 🤡 From nothing??😂😂
i thought the 8 second delay on the moon was too much, so i googled, it says 1.3 seconds...
1.21 to 1.35 seconds the orbit is elliptical.
Sun is 8 seconds.
@Peterbrendanalbert sun is 8 minutes actually
@CommonSenseABCAh yeh, I remembered 8 at least. One of these days.....
I came to comment the same thing.
Errors so simple as this make me not want to waste my time watching the rest of an already proven to be poorly checked for accuracy
This subject is so fascinating, it makes a person realize that maybe we are alone in the universe, we might as well be because the distances are so vast
I'm just along for the ride
Reveals the scale of the "known" universe ✨️
Space always reminded me of a garden.
This is the same mistake astronomers made before the James Webb telescope extended our vision of the Universe. There is no proof that the Universe is finite.
Great comment. I love to imagine that, like traveling across a planet far enough, you come back to your starting point from the other side. Imagine traveling far enough into the universe you come back to your starting position from the opposite side. I'll bet it happens.
There is definitely no proving that the universe is infinite. What a fallacious implication. Finitude is a matter of knowable scale. What came before is unknowable, beyond the chains of causality, before motion through Space-Time was even a thing.
If that's supposed to be a fallacious implication then a finite universe is just as unacceptable based on current observations. Humanity still has yet to prove if the universe is finite or infinite, so stating either of those ideas would be fallacious is stupidity itself.
@datstift610The HOLY BIBLE in Revelation it says with God speaking ‘’ I AM THE FIRST AND THE LAST , THE BEGINNING AND THE END , THE ALPHA AND THE OMEGA ..This tells me God is Infinite and he is
everywhere at the same time … it also says in PSALMS 19: 1 THE HEAVENS DECLARE THE GLORY OF GOD ! I DONT EXACTLY KNOW WHAT IT ALL MEANS BUT I TRUST IN HIS WORD AND GRACE BECAUSE I SIMPLY BELIEVE..! 😇🙏✝️
To the best of my knowledge, there’s no proof that there wasn’t an infinite number of big bangs, which may or may not have happened simultaneously.
(There may be enumerable bag bangs reaching critical mass as I’m typing this.)
That’s why I’m more interested in long range teleportation than time travel.
I’m as far into the future as I want to be.😁
Astounding...and So very very well said!
I think I managed to grasp about 10% of all of that - but what a 10%!!! I may be a bit lacking in the understanding department but I absolutely love the images and the voice trying to help my dying brain cells appreciate something new in their last gasp.
Thank you
😊
I honestly had to pause and stare at the ceiling when you explained the 'Cosmic Horizon'. The realization that entire cosmic histories are unfolding in regions we are physically disconnected from forever gave me genuine existential chills. 🌌✨ The metaphor about the early universe 'building skyscrapers before roads' was such a brilliant way to explain the 'Too much light, too early' problem. It completely shifted my perspective on how rapidly structure emerged after the Big Bang. 🏗 This isn't just a video; it’s a high-quality documentary that rivals big-budget productions. The visualization of the Cosmic Web and Dark Matter filaments was breathtaking. Thank you, Cosmos Dust, for respecting the intelligence of your audience while making the complex beautiful. You’ve visualized the invisible architecture of our reality perfectly. Standing by for the next masterpiece! 🚀🧠🔭💫👏
I imagine the universe just keeps going beyond our ability to comprehend it ….. there is obviously so much we simply don’t know or understand it’s truly amazing
imagine when we make a better telescope
Trump won‘t let us.
@angeliiique-p7swhy? Just Why?😑
They are already building one / build one
But the point is....the objects farthest away are traveling the fastest and accelerating. Within less than a million years we won't see 80 percent of what we can see now. Won't matter if we have stronger telescopes, the light won't even be detectable because most matter in the universe will be beyond our detection.
Every new discovery is another wonder to think about!❤❤❤
It truly is!😊
This is quite interesting as an audio presentation - very well presented.
I do take exception with the artistic graphics shown. It adds drama, but has no basis in what the audio is presenting. It pretty much just repeats the same graphics over and over.
Most interesting when you just listen to the text being read.
Brit here. What fascinates me about astronomy is that it’s all speculation, stars may exist or they may not depending on how far they are from us. Fundamentally in the end it all boils down to one of the biggest words we have ( if ). If we manage someday to travel at the speed of light some lucky person, if I can call them that will find out, but on returning may find nobody left here to share their discoveries with.
But what is lacking here in this comment is the sheer distance comprehension. At the speed of light 186,000 miles per second a human beings life span wouldn't even make it out of our own galaxy let alone to 1000 light years away, 1,000,000 light years away, a BILLION light years away! Grasp that... one light year is traveling 186,000 miles per second for an entire year to reach said point. It is absolutely mind bending to think of the scale of things! So say the traveler leaves at the age of 20, in reality he/she would only be able to travel 30 light years away and then the 30 to return at the age of 80. Thats 30 light years, from earth to even reach the edge of our galaxy (the milky way) is an estimated 25,000 light years. So we really wouldn't really see much more than we can right here on our cozy planet. Crazy right 😲. Now imagine there are billions of galaxies, plus the distance between galaxies. Absolutely insane.
It's mind blowing that the universe could be a forever thing and never end, that amazing fact that we will never know.
Has to be a forever thing. If there's an edge, what's beyond the edge?
The content is top-notch, the visuals are beautiful, and the information is incredibly valuable. One of the best astronomy videos I've ever seen on RUclips!
This video is truly a cinematic masterpiece! 🌌📽 I was completely captivated by the explanation of the universe's 'True Scale'-that mind-bending 93 billion light-years figure is hard to even comprehend. The visualization of the Cosmic Web and how Dark Matter acted as the invisible scaffolding to give galaxies a 'gravitational head start' was simply brilliant. 🕸🧠 The revelation about galaxies being fully formed just 300 million years after the Big Bang (Cosmic Dawn) is a total paradigm shift that rewrites history! 📉🤯 I especially loved the poetic insight that looking into the sky is like reading an ancient archive, not seeing a live feed. Thank you, Cosmos Dust, for such high-quality research and narration. This channel deserves millions of views for making complex science so epic and accessible! 🚀✨🔭👏
👊
Just worked out how big 'INFINITY' is. WOW WOW WOW !!!!!!!!
Do they run a bus service
"NO VESTIGE OF A BEGINNING, NO PROSPECT OF AN END"
This really puts how small we are into perspective.
I have so many documents I'm not playing with anyone anymore
Thanks, awesome presentation. What if dark matter is or contains the other dimensions they think exist, interacting with our three dimensions as matter passes through it.
Think of everything you think you know about how big the Observable Universe is... now cube that. And you are closer to the truth. Imagine how much more there is beyond the Observable. (I love it!)
They can not measure how fast black holes grow. Why do you state that?
The fact scientists don't / didn't think the universe is undergoing some sort of entropy is actually funny. Of course it made galaxies quicker at the beginning.
I really like this video
THIS IS CRAZY!!!
They should have asked me. If I squint I can see out that far. Lots of nights I just stand in the backyard just freaking out about all the stuff going on out there.
If space-time is stretching and light gets pulled flatter (lower frequency, longer wavelength), then reverse back to teh bangbig its clear a gas don't have to expand much to lose energy and condense. Whuts a kilometer now, might be a millimeter 14.3B years back or whatever the ratio is (divide by teh speed of light times 14.3B?). If it isn't that space contracts its scale, then time compresses, or they both concentrate and the nature of Space-Time is condensed along with everything possessing any scale (or unit) in it. An ion of Hydrogen might be the size of a coupla Plancke lengfs or sumfing. A different kind of pressure cooker, to be sure.
I slept really good, Thanks for your contribution 😊
Thats good, glad you liked it😉
James Webb Telescope Just Revealed the True Scale Of The Universe!.......until the next true scale.
Ať tíme 1:54, I think there IS a mistake - the Moon is only 1.3 light seconds away, not 8 seconds?
You are correct. I was getting on here to make the same point. Hard to keep watching when this kind of error is right at the beginning
Yeah the moon would be almost 1.5 million miles away lol
To explain the "earlier than expected" galaxy formations maybe we can consider time ran differently then (faster?). After all space and time are related, and so there was a lot less space back then, since supposedly the universe has also expanded exponentially since.
Absolutely breathtaking. This video turns cutting-edge Webb discoveries into a clear awe-inspiring story about the universe’s true scale limits and mystery-deep science told beautifully.
I've known for years now
Great 👍🏻👏🏻👌🏻☝🏻☝🏻☝🏻☝🏻☝🏻‼️
Thank you!😊
Those early, massive, complex galaxies, suggest our understanding is lacking, and the age of the universe is not what we think it is.
Crazy how all this is in the past and we cant know whats there now for sure
At some point in time, when a person looks up the stars will be gone. The universe will have expanded so much light will never reach us
yes!!! congratulation for video!! :)
Thanks
universe is soo vast
Bro this is an amazing story. I don’t wanna fall asleep and miss it lol be more boring next time jk but seriously… like photons are traveling one at a time across the galaxy what incredibly imagery. It’s crazy how reality works
😂😉
Each every stars in outa space have there own lifes..like earth we have our own star sun we belong to the planet earth
I really enjoyed this and it is interesting to read the comments. Some are very scientific, which science is the backbone of these discoveries, and some are philosophical. I love both, though I am not educated in the science other than my own strong interest.
As a 65 year old retired person, one sentence really struck me though, " Every observer, no matter where they are, sits at the center of their observable bubble."
Science takes us so far, there is ALWAYS a point when we must look UP to the Creator, thank You Heavenly Father !!!
I don't understand if we realy know where the position of the "big bang" realy is. We are at the center of an observable universe and the webb telescope has just extended the border of the obesrvable universe from 14 billion to 46 billion light years but we cannot see the origin of the big bang. Therefore the big bang theory still holds it's ground and we have to accept the fact that the universe is even bigger than we can immagine.
👍
Seems true,..!
Instead of one single Big Bang how about more than one pulse that's why Webb is seeing formed galaxies beyond our understanding?
Then how come galaxies collide?
This was real good information.
Apart from the moon / light / time taken bit... which was incorrect, but not corrected or acknowledged by the author...
To quantify the existence of the unknown you first predetermine not to attempt to observe it.
I am sceptical of light-year measurements. The universe seems very fluid. Gravitational lenses would seem to defy the accuracy of light-year measurements.
They say astronomy grew out if astrology so some ideas you hear are a hangover
I'm just along for the ride . Just worked out how big 'INFINITY' is. WOW
It's relatively big i guess
I don't think anyone has ever claimed that what the telescopes of the time could see was the extent of the total universe. Current estimates, even before the webb telescope, was that the actual universe was many times larger then what we could see, and possibly infinite. We don't know, and we can never know because most of the universe has moved beyond the ability of its light to reach us (and space continues to expand).
The issue of how quickly the high energy soup of the earliest universe progressed to stars and galaxies is an entirely separate issue.
So space is currently expanding faster than light can travel? And the expansion has accelerated to be where it is now. How do we measure this?
0:24 We knew the 93 billion light year diameter of the observable universe about twenty years before the Webb telescope became operational.
So, if the telescope could see the big bang, it would be...a wall of faint energy? Would it look like what we see in the...background? What we perceive?
I really like this video 😍😮
Thank you!😊
The edge of the observable universe is exactly what an event horizon looks like from the other side.
Want to see what happens inside a black hole? Look around.
Why couldn't we get a clear pik of atlas 3i 🤔
What if the “big bang” is actually just one of many explosions in a universe so big it’s not possible for us to see it a part of something much much bigger similar to the universe we know where a big bang is basically like a galaxy one of many more?
If the light from beyond the "cosmic horizon" can no longer reach us, how do we detect the "cosmic background radiation" from right after the big bang?
The only explanation I can think of is
what we know about time and how light travels is wrong maybe we are not looking into the past??
So how did Earths particles get here from 13bn years ago, form Earth etc but the photon was playing catchup 08:20
Haha! Expansion.
Isn't stuff great.
I really like this video 😍
Thank you!😊
Ignorance = Fear so you look out a crack in your wall of fear & see only 1 % of all & pontificate on what is reality to try to quiet all the fear eating at you! Always has been & always will be so embrace that first before spewing all that Ignorance & just say we do not know, then you can expand the knowledge of all that you fear.
eviously
Nature does what It wants, not what man wants.
The universe goes on forever, and the James Web telescope doesn't have the ability to see more than a small bubble. When I was in school, astronomy professors were telling us that the Milky Way galaxy was the universe. My smartphone takes better pictures of the sky than our best telescopes back then.
7:30. Or. . . The Universe is much older than we have previously thought . Much, much older.
14:06 Carbon and Oxygen are products of a normal fusion process. . . Co-existent with first-generation stars
93 billion lightyears across.
So from my reference point roughly a radius of 46,5 lightyears, right?
Some older postulates stated a radius from observer to event horizon with 13,8 billion lightyears.
Let's say there are some relativistic Doppler-Effect phenomenons to consider. Let's just estimate them with an variance-factor of +1,0628 (1+0,02π).
This would extend the radius of observable space-time to an amount of roughly 14,67 lightyears.
Let's take this presumed value and multiply it with π.
The radius of the observable universe would stay at 14,67 lightyears. But the event-horizont at those 14,67 lightyears might be curvy and could allow is to have a glimpse in the corners that couldn't be seen without the curvyness.
We might could see 14,67 multiplied by π ≈ 46,078 lightyears of universe, that is actually already hidden from the reference point of the observer; e.g. JWT. 46,078 multiplied by 2 would be 92,156 lightyears across, right?
Why are so many people have the weird idea, that their reference point is the only one. The Big Bang didn't happen at a specific point. Before the Big Bang, there was no point and therefore there was no "before". Consequently the Big Bang happened, it happens and will happen all at once - everywhere and continually at all times. It's partially out of your reference frame.
So your perception of time matters to yourself in your universe perception. It doesn't matter necessarily to other reference frames.
I don't understand this obsession to try to set a standard space-time exactly there where those people are perceiving their version of reality. The Big Bang didn't will happen right now, where someone is shitting. If that would be the case, the universe would be even more hostile than it is already 😉
What part of infinity did they not understand. Was it "U" or was it "E" in the word UNIVERSE or the UNIVERSE. We can not see the other side because there is no other side. Like time, it has no beginning and it has no end. Time and Space. We will never visit or see these places. They can only exist in our minds eye.
What if scientists created something that could only trigger to start its operation only once it reaches the ort cloud that way we could actually, eventually see further, and yes, I do know that's only.possibke with a quantum entanglement type concept, but, didn't Google and Harvard or mit create a quantum chip, so technically we could start some type program to do that, I'd be the 1st to volunteer. Call it the snow probe
It's all guess work. I don't think we'll truly ever know the full size.
The amount we don't know is unmeasurable.
Our arrogance is our ignorance
I am what I am I know that you know and I'm the one homeless and don't have money I don't think so
The universe is an amazing place. We are just now able to envision creation in the cosmos. The next step will be to have contact with alien intelligence. Alien societies are highly evolved. We stand to learn a great deal.
Science is the gateway drug to the truth!
We should go back and bring back some dinosaurs 🦕
The word is farther, not further.
So.... according to physics, there could be much much more thats so far away the light might not have gotten here yet. How would we know? Especially if its moving opposite our travel.
Its already crazy enough to think about how nothing outside our solar system is where it looks to be anymore... all that stuff they are looking at 300,000,000LY away could have exploded or gone out by now for all we know.
If we do ever somehow manage faster than light travel... how do you get anywhere? The closest thing has not been where it looks to be in more than 2 years. You would have to account for the realtive motion of everything, you can't do a straight line, you would miss. Though I suppose the ship is part of that moving system already by virtue of having existed within the gravity well of something that is moving.
Nothing is "still" if compared to an arbitrary point in space, its all moving pretty fast in our reckoning but might be "still" by the Universe's. And an arbitrary point in space is a hypothetical situation anyways... its impossible to be "still" while within a moving system.
Flat Earth weirdos don't get that and fries their brains. 😂
I don't know. Its a lot to think about and I am not an astrophysics expert.
We are so very tiny, and for our scientific advancement and observation, don't really know anything.
Nuts that we can see stuff that happend millions of years before life even existed here.
So theoretically could flying pigs exist out there lol
I hope y'all are happy with coming agenst me
Imagine if what we are actually looking at is the whole universe but what if our whole universe as we know it was actually a galaxy and there are trillion of other galaxy 😮😮😮
er um-it takes about 1.3 seconds for light to travel from the moon to the earth, not around 8 seconds. Ok Ok, others noticed this!
it is called engagement farming, a glaring mistake to gain comments
My question is what physical law dictates that the universe began at the same instance everywhere? Can some areas be older or younger than others?
Because everything in the universe is recorded information. Time is the rate of observation.
Everything in the universe was created from a single point. Everything in it was created from that point, including us. Expansion is the process of creation from that point. That Expansion continues as we speak and will continue into the indefinite future until one of several possible events occurs to change it. We have no idea what event that will be or when it will happen to change this Expansion to something else.
@amazonianfromboston1933also they thought that there would only be a couple of elements because they could not have been formed yet, elements like carbon, h20,co2 and so on, this could only have happened because of pressure being build up over a period of billions of years, then released in the universe as buildingblocks, except the webb telescope proved there where all kinds of elements in the " so called early universe " the webb telescope has sensors that can interpret the data,
@amazonianfromboston1933and their are alot of other things that dont add up! Science needs only one miracle to lay its head on and thats the big bang so they can build on their theory
@worldclassishand particles behave differently when observed, also very interesting, maybe the universe is showing us what it wants us to see, but is it there when not observed! Reality is stranger then fiction!
The author is dancing around the problem of our horizon of view-ability, and the edge of the universe. If the remote galaxies we can see appear more complex, it is likely the universe is much older and much larger.
Al Hamdulillah…
Why cling to a Big Bang theory? Why not entertain that the universe is older than once thought. If a big bang is that important, then move it back another 7 or 10 billion years.
Because the cosmic background radiation is currently viewed as the limit of the universe's age. Currently, it's seen as the "beginning". So we can't push it back any further. At least, not until there's evidence that the CBR is not the beginning of time, the beginning of cause and effect. Currently, scientists believe it's more likely that they have issues in the theory of the formation of matter and stars than the age being the error.
I don’t think bigbang i the problem its dark matter and dark energy. We have no clue
no.. the moon is 2 seconds away... in light speed. you see it as it was 2 seconds ago
We are most likely still on the first page of the book called THE UNIVERSE. We hardly know nothing yet. Just my opinion.
