So hypothetically if we could reach the edge (if one exists), what is there? I mean would we just go into nothing? Or is it like earth, where if you travel in a straight line long enough you end up back where you began? Space BLOWS MY MIND. It makes me sad that we won't ever see the very very beginning of it, or reach other galaxies in my lifetime. There's so many things I have questions about that I won't ever get an answer to and that kind of makes me depressed when I think about it too much.
We won't reach other stars in our lifetimes let alone other galaxies FFS. It is likely we will never even reach another star in thhe entirety of human existance.
I have similar feelings of being sad cuz i wont live long enough to know the truth. However, what makes me cool that humanity will never know the truth even in a billion years, they wont even be able to travel outside the solar system. You might think it is possible but when you look at numbers you will understand that even our solar system is very huge for humanity power resources to handle. Travelling outside the galaxy is a dream will never come into reality. Even voyager 1before 30 years and still travelling at tremendous speed is still exist in our galaxy and didnt reach the edge of it
He needs to say 100 billion galaxies in the "observable" universe. There is absolutely no reason to believe we are at the center of everything and that there are no galaxies outside the distance we can see based on the light that has so far reached us.
He said that seven years ago. Now we know we are on the order of 10 billion or so galaxies in our little cluster of galaxies, which is one of 50 or so billion clusters in our local super cluster, and on and on.... as we get better technology, we learn more about everything that makes up our one universe in what is possibly the great multiverse or quantum universe. Who know for sure? I just like kicking back in the back of my truck way out of town, listening to Pink Floyd- Dark Side of the Moon and watch all the wonders in the night sky. Greeting from west Texas Ya'll
eminemishh Any/everywhere in the universe you are will be at the center. It's a sort of paradox. The observer defines the universe from it's point in time and space.
Mean while, here on earth, we size our problems into politics, having no idea how insignificant we are to the size of this thing we intent to imagine - the universe.
Considering the universe is a bounded infinity. From the observer's perspective, ours, the further we look away, the more we see into the beginning of space time. Since the universe is expanding into that direction, away from us, I suspect it is expanding, quite literally, into it's origins-the singularity from whence it spawned. The future is, in fact, becoming the past.
Our world and our understanding of the universe has changed so much in just a hundred years you just have to wonder his much it will change in a thousand years.... If we survive
The latest estimates I have read on the number of galaxies in the visible universe is 2 trillion, not 100 billion. But even 100 billion galaxies is a number that you just cannot rap your head around. The universe is indeed one huge and very mysterious place.
If we say that the universe has a boundary, what would we call the space/zone/area on the other side of that boundary? Is the outside not still considered as a part of the universe?
Not Sure Thanks for the response Brother. When I look up the definition of the word Universe, it can cause some confusion due to the fact some definitions include "the bulk", and others do not (even though they don't refer to "the bulk" by name. I think that it is important that the defiinition be made clear in order that people understand what is trying to be implied in science video's. This changes my view and understanding on so many things, and know I can understand what other science video content makers are trying to say. Peace and Respect Brother.
***** The first dimension is a line. Add the second dimension and you have a plane. Add the third, and you have a box. Another way to look at it is length, area, volume. Your example fails because it excludes the third dimension, and space is 3-D.
the universe is infinite in every direction, the human mind cannot process that concept and never will. This precludes thinking as to what's beyond the edge of the universe
No. Either the universe has an edge or it's infinite. Something that is infinite doesn't have an end-point, by definition. Something that has an end-point isn't infinite.
The universe can't be infinite. If the universe had a beginning about 14 billion years ago then the universe must be trans-finite meaning that it is unimaginably huge but still has a finite volume. If you were to keep going in one direction you would eventually come back to the place you started because the universe is a curved 3 dimensional surface of a hypersphere.
There's a lot of confusion about whether the "edge" being talked about is the edge of the defined observable universe, or about the larger (maybe "infinite") universe of which it's just a small part. The only "edge" to the observable universe is simply the limit of our astronomical observations of light which has been traveling since the big bang. The size of the observable universe expands each day with the 24 hour age increase of the universe, and simply expands into the larger universe which surrounds it. As for the universe outside of the observable universe, it's size is unknown. What sort of an edge it has if any is unknown. But the measurements of the WMAP and Planck satellites against the "surface of last scattering" of the Cosmic Microwave Background radiation indicates that the large scale topology of the universe is "flat." Which is to say "Euclidean"......that the sum of the interior angles of a universe-sized triangle based on the variations of the CMB radiation totals 180 degrees, as close as it can be measured.
If there is any boundary in the Universe, the question is: what is beyond it? I wouldn't be surprised if there were other Universes like ours separated from each other with empty space.
Every time I sit down and really try to wrap my small mind around what the universe is, or how large it is, or how mathematically reasonable it is that there is life on other planets and things like that I get this strange feeling. It's almost like excitement that comes with shortening of breath and other odd sensations. Is this weird?
It's called 'wonder' - it is the catalyst for our journey into the cosmos. I feel our far off descendants will view us with great affection, and possibly envy us living in an age of ignorance and discovery. They may even say to their children when they put them to sleep at night: "A long long time ago, on a blue planet somewhere out there, people would wish upon the stars that me and you now travel amongst. If it wasn't for them, we wouldn't even be here - If only they could see how their wishes came true. Now, goodnight you grey, massive headed little telepathic princess, and sweet dreams."
asre wefwefw Oh goody! Another atheists. What else can you share with the world that nobody gives a flying hoot about? Are you gay? Are you black? Have you ever had a heart attack? Can you sing? Do you swing? Have you ever felt a scorpion sting? What's the meaning of your life? Are you happy and rich, or are you lonely and filled with strife? Are you angry and mean? Is your house messy, or do you keep it real clean? I guess it really doesn't matter, so I will quit with the chatter. When you're dead, you are dead, and that makes you mad as a hatter.
snakebitmgee I'm Gay and Black and i belong to the middle class... I'm lonely and happy and yes, dead is the end for all of us until science invents the inmortality. I invite you to make science i don't caer if you believe in god or not (that's your problem and you are liying to yourself) but please do science.
plain & simple we will never figure out how large the universe is. humans will be dead in a few thousand years and the cycle of 'life' continues on other planets in different forms.
there is also a 3rd possibility: imagine a balloon, its surface is not infinite big, but you can walk around on it and never hit the edge. and when you blow air in it, it gets even bigger but is still infinite as it was before. i think spacetime is a bit like it.
+fanjapanischermusik Just as when human thought the earth was flat, they could not conceive what come after the edge of the "observable earth", so they said when you go over the edge, you fall in oblivion. And it turned out the earth is a kind of a "infinite plane" in the shape of a sphere. Maybe we just need to change the way we observe the universe...
I thought this video was very good. I also think that many of the critical and sarcastic comments are made by people who need to drop their own intellectual pretentiousness and ask themselves who this video is aimed at? Don't forget not everyone is as wise and as all knowing some of you seem to be. Many people are approaching these types of questions for the first time, for such people this video is an excellent first step. Although now retired I have spent my life teaching maths and physics at college and university level, this is exactly the type of material I would present to my students who are just starting out on their journey of discovery. I think the makers of the video have struck a good balance of being informative without being too speculative or self indulgent - unlike some of the posts that they have invoked. Well done!
It's expanding into something close to nothing, but different than the day before. And that's when I saw her, ooh I saw her. She walked in through the big bang, big bang.
Naaaah... Don't cave to impatient people... (Your craft is sound). I liked the intro as it helps me mentally pull focus on the subject we are dealing with. It's like you have been outside in the sun, and it takes your eyes a good 45 seconds to adjust to a dark space. Similarly with the topic in hand, most people transitioning to this video are having to deal with the flotsam and jetsam of everyday life... So I find the introduction helpful to change "Metal gears" and be able to visualize and in a sense try to intuitively feel or wrap one's head around the vastness and truly epic naure of the topics we are dealing with. It's all good ! :-)
If the universe has boundaries, it's said that we can never reach the border because it's constantly moving away from us. However, who's to say our Galaxy isn't close to the border of the universe? Still too far to detect it, but still right on the edge, moving along the border as the universe expands.
We know that we are at the CENTER of the OBSERVABLE Universe by definition. The Observable Universe is the maximum distance than we can see when we look out into space. Since we can see the same distance in all directions, then we are at the center of the Observable Universe. The radius of the Observable Universe is defined by the Particle Horizon, which is calculated to be at a distance from the earth of over 46 Billion Light-Years in all directions. So we're over 46 Billion Light-Years from the edge of the Observable Universe in any direction we look, and we know that the Total Universe extends beyond that......probably FAR beyond that. So even if there is a boundary to the Total Universe, we know that we are very far away from it....at least over 46 Billion Light-Years. A "Veritasium" video on TH-cam discusses the Observable Universe and the Particle horizon. It's titled: "Misconceptions About the Big Bang,"
One thing I often wonder is if the Universe is finite and has an edge, then what would it be like for a civilisation living in a galaxy on the edge, in one direction there would be nothing and in the other there would be everything. Very cool
Rasverix Xyleighraq there is no end to the universe just like you can count for ever ! There is no edge to anything ,it goes ever increasingly smaller and same bigger !
Rasverix Xyleighraq , I often wonder what the night sky would look like if we were in a different location within our galaxy especially closer to nebula, would they have been part of mythology? The Titans perhaps? Being at the edge of the universe would be a natural variation on that theme.
The Universe has a membrane at the edge and on the membrane, written repeatedly in a plethora of languages is the legend, "Slow, Spaced Out Hippies Ahead!"
The Truman Show, all the way out. Something beyond the transfinite boundary is replaying our universe’s recorded spacetime tape. Heck for all we know, it might even be a malicious extra-dimensional child.
Mnakekeli Ngcamphalala I don't quite understand what you mean by that, but if i somehow understand what you've asked, "the universe isn't located anywhere, it's just there."
Mnakekeli Ngcamphalala That question doesn't seem quite logical to ask as the universe doesn't have any other points of reference we could use, *that's detectable*, that we could compare *it* to. So far as we know, its just there, expanding .. If you were to ask, *" Where our star & its surrounding planets were located within our galaxy "* or *" Where the nearest star system to our solar system is located "*, then yes, those are questions we could correctly answer as scientists have studied & calculated the distances to acquire the answers to those questions. & if you're curious to know what the answers are, to the above questions; - Our solar system is located in the outer reaches of the *Milky Way Galaxy, & is a spiral galaxy. - *Alpha Centurion* is the closest star system to our solar system, ( its *4.37 light years* away from us ). :)
Mnakekeli Ngcamphalala To ask that you have to presuppose that our universe has boundaries and out of the boundaries there are more universes. As we don't know if our universe is infinite or not and we don't know if there any other universes out there, your answer cannot be answered! Sorry!
E=MC2 also says that space, time, and energy are finite. If the universe has a beginning then it has an end. Everything loses energy with the passing of time. Then energy will end and the expansion of the universe will reverse into shrinking and it may be faster or earlier than we ever imagined.
The more I learn about the universe, the less tangible it gets. Space and time linked, third dimension is an illusion, space is a hologram, energy out of nothing, virtual particles, time is an illusion, etc... I did not know that a year ago... If this goes on I think in a few years time, I will learn that my whole existence is an illusion created by my own illusive brain or something?
Ronald de Rooij Good question, when I read idiotic posts like yours, I come to the conclusion with evidence that this man has written an idiotic comment. Therefore, the only plausable reply, is to ask the question "are you an idiot". If you dont want to be called an idiot, then dont write idiotic comments, its that simple.
Ronald de Rooij The fool who knows he is an idiot is at least wise to that respect. You dont even know you are an idiot. Which makes you the biggest idiot of all.
A friend of mine was depressed because he heard the sun will only last another 5 million years. When I explained that in fact the sun will last another 5 BILLION years he was very much relieved and very happy again.
These videos by Deep Astronomy are really well done and excellent explanations of so much of what we know, and what we're still learning, about the Universe we inhabit. Wonderful stuff!
If our Galaxy was the size of a Neutrino, the size of the observable universe would be about the size of a Hydrogen Atom. All things being relative we should be studying and spending more on the Sub-Atomic "world". We like to think BIG but thinking small sort of frightens most of us...
So if it's infinite with no boundaries then how did the medium of an infinite universe suddenly come into being and what existed before it came in to being, and if it was nothing then then what defines nothing and how could the state of nothing become a state of something, and has the state of nothing existed for an infinite amount of time beforehand and how and ughh wtf
Because the universe complete with space, time, energy and laws is thought by God. There can be nothing material where there is no space. Our reality has been carefully thought so that everything fits. And we don't even know it. He has still more computing capabilities. Infinite.
Adam Harrison I think the universe is infinite and always existed, but is also always undergoing change, with the rate of change itself varying. However, there is underlying structure to the universe which is not entirely entropic as "scientists" would have everyone believe. This is easily seen in spiral galaxies and the spirograph pattern of magnetic fields, etc.
Adam Harrison something can’t come from nothing Everything came from the unmanifested absolute which is perfect Those in the know are referring to this thing when they say God
Simple, either an expanding universe into infinity, or an expanding universe which will then contract, resulting in a crunch leading to another big bang. Not sure how you prove either hypothesis, but go for it, and I wish you luck.
when there are no answers we simply give up and use the god did it theory, fortunatly not all of us are quiters and seek the answers through study and observation, lets hope we never stop learning, and if there is a god he shouldn't judge us for being courious.
Maybe we are looking at this at the wrong angle or perspective. I imagine the universe as a 4th dimensional balloon.Imagine you are inflating a 3D balloon then 2D creaturs thrive on it. They will think its infinite because there is no edge and they think that their universe started from a "point" but the truth is, it started everywhere. As you indlate the balloon, every part of it expands. So maybe our universe is like that. Expanding into a 4-Dimensional space.
what if our universe has always been expanding and there were infinite amount of big bangs that exploded and expanded the galaxies before ours. If that is true wouldn’t it make sense if the civilizations from early big bangs 1. gotten so advance that we are not worth visiting. 2. Extinct.
@4:10 " if that is true however, then the boundary is so far away that we cannot see it, and it can therefore never ever affect us." Right. Because things that we cannot see never ever affect us. Like germs and radiation. Good logic there
There are no exact answers, the universe appears to be like a balloon that continues to expand. What is the expanding balloon expanding into? Nothing, it creates it's own space. If there is an end, then logically there must be something outside of that.
Ya, kinda like a balloon but whats inflating that balloon? its more of that space that you just called "nothing". Its not "nothing" it may be a NO THING but not nothing, its the smallest of the smallest of the small and everything in the universe is in it right now.
what is the space between electrons or quarks or anything in that scale? It's not air of course, it's not gas (we are on a far lower scale) what is it? It is empty and consists of nothing yet it provides some distance in space...Maybe I am just ignorant...
The latest theory is everything is a tiny string of energy. So you don`t think about space. The universe is and we are just uneven strings, with one end or other being a bit more energetic than the other. So when we try to detect atomic particles, all we are doing is detecting the heavier bit. And to me it kinda explains quantum theory, if these heavier bits on the string move around.
easyeagle2 thank you for the reply, but the question then just changes to: what is between the tiny strings? :D I am guessing energy and it is made out of some tiny tiny particles, then I ask what is between those and blah blah...Do we even need to know? :)
String theory is (currently) physically untestable and entirely theoretical, constructed from mathematical models and proofs. But I think Ludak was asking "what is space on small scales?" Well, we don't know. It's energy is greater than zero everywhere and it's expanding.
Question: I've heard some say "new" space time is being created, and that causes the expansion. But ive also heard it said that time-space is simply being stretched....which one is it?
I think it's more accurate to say the former. New spacetime is created, but the question is, where does it come from? The research into dark energy hopes to settle that issue. Because the universe is accelerating as it expands, there is a force associated with that expansion. Forces need energy, so what is it? And that's a burning question in cosmology right now.
I see. Thank you for clearing that up for me. I love your channel. And if you dont mind me saying so, its one of my favorite places to go after I smoke a joint. Cheers!
both, the idea around dark energy is that space itself is growing from the inside, so space isn't exactly stretching but new space is coming into existence everywhere, so in between two bodies more space is coming into existence, its just too small to see on a small scale like inside of a galaxy, it's only relevant across billions of light-years. Its why the universe in a way has no outer edge because the expansion of space moves at a rate faster then light speed could travel so nothing could ever reach the edge.
Dark Energy, if it in fact exists in the way we think it does, is raw creation. Where it is not, there is nothing. Where it is, there can be something. Theoretically, Dark Energy's expansion is defining a finite space (our universe) within a blind infinity. Though, who are we to say that there aren't other pockets of dark energy doing the same thing, I.E. _other universes_ which may eventually contact and connect with our own.
It may be that the universe is not 'expanding' into anything, but rather 'thickening out': what began as 'empty space' becomes progressively more densely filled with light & gravity, and it thus takes longer to get from A to B (in both terms of time and space, the continuum being space-time after all). From the perspective of those within 'the universe' it is expanding; from the perspective of those at the very (Escher-like) edge of the universe, they are simply taking longer (and experiencing more) to get anywhere.
I believe what you mean is "Given enough time all matter changes (sometimes with explosions) through space with gravity". I agree with you that matter didn't just come into being something from nothing.
They would see basically the same sort of things we are. A never repeating pattern of galaxies, each becoming bluer and younger and smaller as duo look further out, then would see the point the universe reionized in the cosmic microwave background.
In the video he said that if there is a boundary we can never see it because the universe is expanding. I've got a fair understanding of the expansion of the universe concept (I couldn't follow the math to save my life but I think I understand the concept fairly well) and of course looking from earth we could never see the boundary if there is one but if someday we derived a technology to warp space to travel faster then light or create wormholes and teleport then what is stopping us from seeing the boundary?
hmmmmm what if the universe is super damn vast so that even ftl and wormholes wouldn't get us there faster than the universe is expanding? like, we'd always be behind. or mebbe the universe is inherently unstable near the boundaries? eh who knows
If you imply a boundary for our universe, which is everything there is, then by definition there has to be something "on the other side" of that boundary....which would be everything that isn't. If you can make sense of that, then please inform us.
Alan Hill Well of course I have no idea what the boundary would be like or what the other side would be like but in the video he's saying that if there is a boundary that we can never see it because of the expansion. He doesn't say we can never see it because the other side is the opposite of something he says that we can't see it simply because we can't get to it. Did I misunderstand that part?
Time is the barrier which keeps us imprisoned on this planet...when we break through the perception of finite, linear time, (which is an illusion and thus CAN be broken through) we become infinite beings with multidimensional knowledge as a natural consequence of that. That is what the mystics were alluding to and that is why the deepest Kabbalah from two thousand years ago was able to outline principles that the new physics is only now beginning to "discover". It is not a matter of "understanding" intellectually through equations, it is a matter of us realising, experiencing and becoming that truth, which we come to by dissolving the illusion of our perception which keeps the truth hidden from our eyes. Many people at this time are beginning to wake up. This is the next stage in our evolution, much needed, when you look at the mess we have made of this planet, but forgivable as you would forgive a toddler for making a mess of its playroom. Our race has merely been in its infancy for the most part of commonly remembered history, though there have always been those souls who have seen the truth and tried to point the way.
The barrier IS our temporal illusion. Our flawed perceptions are thoughts and concepts about reality, not reality itself. Our consciousness is non physical, and thus if we can ascend above our normal perception, we can connect with the limitless of the quantum field. People are stuck in varying mind patterns, according to their belief system and conditioning. Youa lways find that the achievers in life are the ones who dare to break through their own perceived limits, but that breaking down goes on a long, long way... Our consciousness makes up the hologramic reality we see around us, affecting every atom and every particle, and by changing our consciousness, we can change ourselves and our life circumstances for the better. If you are going to live in an illusion, you might as well make it a good one!
"The fabric of space and time is expanding" This is why I (being polite) call these people "babbling idiots" *First-* Time doesn't exist, it's merely a measurement tool created by humans to measure how long it takes for a particle to move from point *A* to point *B* and, *Second-* If space was "expanding" the most basic logic tells you that we wouldn't be able to realize it because *EVERYTHING* would be expanding at the exact same rate. Hence the solar system would be expanding, the earth (and everything in it) would be expanding, WE would be expanding, and of course our measurements devices would be "expanding" as well, *AND* with it the measures themselves.
just because you dont understand something, dosent mean that the person explaining it is an idiot. "first-" time does exist, and its not a "measurement tool" created by humans.. its a word created by humans to describe something (like everyother word). www.oxforddictionaries.com/definition/english/time when people talk about the "fabric of space and time" they are referring to this: en.wikipedia.org/wiki/Spacetime
Merlith Gero You are just regurgitating like a parrot what these *babbling idiots* CLAIM. Yes, it's a word created by humans to describe something, indeed. It describes *how long it takes for a particle to move from point A to point B* But, If like you say, time "does exist" = *prove it* SHOW us "time" As for "what they are "referring to" when talking about this, the entire thing is based on the *presumption* that time "does exist" So if you are gonna refute what I said, do so explicitly. Show us how we would be able to perceive the "expansion of space" when ALL of space (that is *the entire Universe and everything in it*) expands at the exact same rate which would OBVIOUSLY include the space contained in every single atom causing *EVERYTHING THERE IS* to remain at the exact same size/distance in relation to everything else. Let's see your "understanding"
***** Time was not invented by man. The MEASUREMENT of time was invented by man. Just like how we didn't invent a meter or a kilometer. These things have always existed, we just found a way to measure them. Run along now.
OfArgento The measurement created by man measures how long it takes for particles to move from point A to point B. That's what it measures. It doesn't measures "time" simply because time doesn't exist. But, (if like the previous regurgitator) you pretend that "it does" you are welcome to *prove it* as well. SHOW us "time" wise one...
***** my gawd. you are an idiot.. i even linked you the definiton of the word and youre still incapeable to understand basic logic. its NOT a measurement tool. the fact that everything age, that a clock ticks, that something rust or rot, creatures evolve, planet circling around the sun.. ALL of these are examples of time. its just a bloddy word to explain the indefinite continued progress of existence and events in the past, present, and future regarded as a whole. if you cant grasp something as simple as this, then you clearly lack the intelligence to understand astronomy, so i advice you to watch something else. how do we know the universe is expanding? well, the answer is luaghably simple.. because through years of analyzing and calculations, we can see that things are moving further away from each other. why is this difficult to understand? en.wikipedia.org/wiki/Metric_expansion_of_space the only "babbling idiot" here, is you.
Maybe we are like nanoscopic cells, thinking that we are a extraordinary intelligent species and amazed by how "huge" the universe is, while we, along with our galaxy are unimaginably "small."
Why would that scare you? In this immense Universe it is almost guaranteed that there are other beings, somewhere, wondering the same thing. Nothing to be scared about!
Left out one important fact: the expansion is so fast, we may never see other galaxies in the future and our future generations may never know there are other galaxies in the universe, or even there's a universe. We are alone. Are we an anomaly, or the start of something? We may never know and our curious and limited minds must accept that's a fact we must live with.
****random thought***** when we are on earth we look outside this sphere and see stars and planets and galaxies ..... what if the observable universe is just another sphere that we are in that we could escape ..... and we could get outside of it and look down onto our universe ..... and see other universes existing inside another sphere!!!!! We may never know just how small we are in the grand design!!!! I'm not offering any science here or theology just a random thought based on pure imagination!!!!!
It may not be so mush that the Galaxies are expanding out into new space but that new space is getting in between galaxies. OR. its not so much that galaxies are moving away from each other but more space is moving in between them.
***** In other words, no one knows? Is that what you are saying? But surely, one can find out. Isn't that what science and cosmology is about, finding how the world of nature works? So why do you want t give up on it?
Gunter Raffel It was not meant to be a scientific answer. Has for science, they cannot know what is not observable. We would need to step outside the universe to see. There are things science will never be able to answer. Things like; Why anything instead of nothing?
hellavadeal ok, that makes perfect sense. It would be difficult if not impossible to describe a accurately describe the true nature of a bottle of Coca Cola if one has lived only inside it. An exterior viewpoint would be required. Science does not dare to venture that far, but why should that be impossible?
At the very end of the universe there is a tax and revenue office
No, there is a restaurant
Dmv for sure.
You wish Charles
*(cries)*
I just mentioned death & taxes today!!! Lol🤣🤣🤣
500 million years... awwww universe baby pictures. We were so cute back then.
They could have shortened the video by just saying "I don't know" the end.
Well said.
This is pretty much 90% of the Astrophysics content you find on TH-cam ever since the pandemic hit.
Thanks
So hypothetically if we could reach the edge (if one exists), what is there? I mean would we just go into nothing? Or is it like earth, where if you travel in a straight line long enough you end up back where you began? Space BLOWS MY MIND. It makes me sad that we won't ever see the very very beginning of it, or reach other galaxies in my lifetime. There's so many things I have questions about that I won't ever get an answer to and that kind of makes me depressed when I think about it too much.
We won't reach other stars in our lifetimes let alone other galaxies FFS. It is likely we will never even reach another star in thhe entirety of human existance.
I have always wondered since I was a child.... what is beyond the Universe...
There is a glass ceiling...
judsonkr hence, "hypothetically".
I have similar feelings of being sad cuz i wont live long enough to know the truth. However, what makes me cool that humanity will never know the truth even in a billion years, they wont even be able to travel outside the solar system. You might think it is possible but when you look at numbers you will understand that even our solar system is very huge for humanity power resources to handle. Travelling outside the galaxy is a dream will never come into reality. Even voyager 1before 30 years and still travelling at tremendous speed is still exist in our galaxy and didnt reach the edge of it
Now I know why the space bar on my computer is the largest key. I get it now. Space is big.
Kay why ess
Very very big.
He needs to say 100 billion galaxies in the "observable" universe. There is absolutely no reason to believe we are at the center of everything and that there are no galaxies outside the distance we can see based on the light that has so far reached us.
He said that seven years ago. Now we know we are on the order of 10 billion or so galaxies in our little cluster of galaxies, which is one of 50 or so billion clusters in our local super cluster, and on and on.... as we get better technology, we learn more about everything that makes up our one universe in what is possibly the great multiverse or quantum universe. Who know for sure? I just like kicking back in the back of my truck way out of town, listening to Pink Floyd- Dark Side of the Moon and watch all the wonders in the night sky. Greeting from west Texas Ya'll
Brian Acctually the earth is at the "centre" of the observable universe.
Correction-our planet is at the center of our observable universe.
eminemishh Any/everywhere in the universe you are will be at the center. It's a sort of paradox. The observer defines the universe from it's point in time and space.
That is correct. It is also correct for every planet.
Mean while, here on earth, we size our problems into politics, having no idea how insignificant we are to the size of this thing we intent to imagine - the universe.
ikr.....
Well unless we screw up big time and destabilize the Higgs field, thus ending all of the universe.
bigdog1 i hope you are trolling

Then you would never use your brain to think ever again...
This video really makes you think: "where the hell are we?"
Imagine if life didn't exist. Where would anything be?
Rob N If existence did not exist, then we are trapped in in a non-existant dimension
If nothing existed to measure the size of an atom, would it be infinite in size? Would it be everywhere and nowhere?

It blows my mind to know that infinity space exists
"Two things are infinite. The universe, and human stupidity, and I'm not sure about the former." -Albert Einstein
@Dan O'Moore former means the one before just so you know
@Dan O'Moore it's fine!
Notice how he didnt comment about the latter
@Dan O'Moore no my point is he didnt actually say whether or not he thought human stupidity was infinite
@Dan O'Moore well he implies it but doesnt say it...and a genius like him likes to throw riddles like that out there.
Keep looking up. Keep looking out. Keep looking in.
I am looking in. I can see right now through your window what you are doing.

I love this stuff.
Considering the universe is a bounded infinity. From the observer's perspective, ours, the further we look away, the more we see into the beginning of space time. Since the universe is expanding into that direction, away from us, I suspect it is expanding, quite literally, into it's origins-the singularity from whence it spawned. The future is, in fact, becoming the past.
Our world and our understanding of the universe has changed so much in just a hundred years you just have to wonder his much it will change in a thousand years.... If we survive

The latest estimates I have read on the number of galaxies in the visible universe is 2 trillion, not 100 billion. But even 100 billion galaxies is a number that you just cannot rap your head around. The universe is indeed one huge and very mysterious place.

Neither did that time.

CANAL GG Ye, modern scientific view of time is bizarre,
Is that a haiku?
If we say that the universe has a boundary, what would we call the space/zone/area on the other side of that boundary? Is the outside not still considered as a part of the universe?
it is called " the bulk"
as described in M theory
Not Sure Thanks for the response Brother. When I look up the definition of the word Universe, it can cause some confusion due to the fact some definitions include "the bulk", and others do not (even though they don't refer to "the bulk" by name.
I think that it is important that the defiinition be made clear in order that people understand what is trying to be implied in science video's.
This changes my view and understanding on so many things, and know I can understand what other science video content makers are trying to say.
Peace and Respect Brother.
***** The first dimension is a line. Add the second dimension and you have a plane. Add the third, and you have a box. Another way to look at it is length, area, volume. Your example fails because it excludes the third dimension, and space is 3-D.
Sebastian K. "space time curvature"
No such thing. That volume can be infinite destroys your theory.
Sebastian K. "What is gravitational lensing then..?" Nothing that proves such curvature.
the universe is infinite in every direction, the human mind cannot process that concept and never will. This precludes thinking as to what's beyond the edge of the universe
No. Either the universe has an edge or it's infinite. Something that is infinite doesn't have an end-point, by definition. Something that has an end-point isn't infinite.
The universe can't be infinite. If the universe had a beginning about 14 billion years ago then the universe must be trans-finite meaning that it is unimaginably huge but still has a finite volume. If you were to keep going in one direction you would eventually come back to the place you started because the universe is a curved 3 dimensional surface of a hypersphere.
SpaceTimeMachine Think he meant the edge of the observable (part of) the universe.
dolphinsatsunset1 np
There's a lot of confusion about whether the "edge" being talked about is the edge of the defined observable universe, or about the larger (maybe "infinite") universe of which it's just a small part. The only "edge" to the observable universe is simply the limit of our astronomical observations of light which has been traveling since the big bang. The size of the observable universe expands each day with the 24 hour age increase of the universe, and simply expands into the larger universe which surrounds it.
As for the universe outside of the observable universe, it's size is unknown. What sort of an edge it has if any is unknown. But the measurements of the WMAP and Planck satellites against the "surface of last scattering" of the Cosmic Microwave Background radiation indicates that the large scale topology of the universe is "flat." Which is to say "Euclidean"......that the sum of the interior angles of a universe-sized triangle based on the variations of the CMB radiation totals 180 degrees, as close as it can be measured.
I respect anyone who try to explain about the Universe. Explaining it, is as tough as understanding it. Excellent work bro!
If there is any boundary in the Universe, the question is: what is beyond it?
I wouldn't be surprised if there were other Universes like ours separated from each other with empty space.
If that is so they would exspand into oneanother would they not.

@@davidhess6593 Space with stars and planets.
Every time I sit down and really try to wrap my small mind around what the universe is, or how large it is, or how mathematically reasonable it is that there is life on other planets and things like that I get this strange feeling. It's almost like excitement that comes with shortening of breath and other odd sensations. Is this weird?
It's called 'wonder' - it is the catalyst for our journey into the cosmos.
I feel our far off descendants will view us with great affection, and possibly envy us living in an age of ignorance and discovery. They may even say to their children when they put them to sleep at night:
"A long long time ago, on a blue planet somewhere out there, people would wish upon the stars that me and you now travel amongst. If it wasn't for them, we wouldn't even be here - If only they could see how their wishes came true. Now, goodnight you grey, massive headed little telepathic princess, and sweet dreams."
Man, your videos are almost like a spiritual experience to me.
I'm an atheist btw.
Same here
asre wefwefw Oh goody! Another atheists. What else can you share with the world that nobody gives a flying hoot about? Are you gay? Are you black? Have you ever had a heart attack? Can you sing? Do you swing? Have you ever felt a scorpion sting? What's the meaning of your life? Are you happy and rich, or are you lonely and filled with strife? Are you angry and mean? Is your house messy, or do you keep it real clean? I guess it really doesn't matter, so I will quit with the chatter. When you're dead, you are dead, and that makes you mad as a hatter.

I'm lonely and happy and yes, dead is the end for all of us until science invents the inmortality.
I invite you to make science i don't caer if you believe in god or not (that's your problem and you are liying to yourself) but please do science.

copying and pasting makes you look like an idiot.
get the fuck out of my thread and spread your poison somewhere else fucking zombie!!
asre wefwefw You must not be paying attention. Science has already proven God's existence.
plain & simple we will never figure out how large the universe is. humans will be dead in a few thousand years and the cycle of 'life' continues on other planets in different forms.
Wow, the graphic sequences illustrating that fraction of the universe we've been able to map is awe inspiring. Beautifully done... many thanks.
there is also a 3rd possibility: imagine a balloon, its surface is not infinite big, but you can walk around on it and never hit the edge. and when you blow air in it, it gets even bigger but is still infinite as it was before. i think spacetime is a bit like it.
+fanjapanischermusik Smart thought.
+fanjapanischermusik Just as when human thought the earth was flat, they could not conceive what come after the edge of the "observable earth", so they said when you go over the edge, you fall in oblivion. And it turned out the earth is a kind of a "infinite plane" in the shape of a sphere. Maybe we just need to change the way we observe the universe...
+fanjapanischermusik so the surface of the balloon would be two dimensional, and we would be unaware of the higher dimension we are expanding into?
+fanjapanischermusik and what is inside the balloon?
+fanjapanischermusik - And what is the space outside the balloon?
I like the voice acting of this man. Its so comforting
I thought this video was very good. I also think that many of the critical and sarcastic comments are made by people who need to drop their own intellectual pretentiousness and ask themselves who this video is aimed at? Don't forget not everyone is as wise and as all knowing some of you seem to be. Many people are approaching these types of questions for the first time, for such people this video is an excellent first step. Although now retired I have spent my life teaching maths and physics at college and university level, this is exactly the type of material I would present to my students who are just starting out on their journey of discovery. I think the makers of the video have struck a good balance of being informative without being too speculative or self indulgent - unlike some of the posts that they have invoked. Well done!
I should be studying, but my brain wants to know the mysteries of the universe.
It's expanding into something close to nothing, but different than the day before. And that's when I saw her, ooh I saw her. She walked in through the big bang, big bang.
its mind blowing to think that out there never ends..its just that everything on earth comes to an end .this shit does my head in...
Best explanation I've ever heard is that space is expanding into itself.
good video, but your intro is too long,I think you should make it shorter in the future.
I know, people have pointed that out. Later videos have 15 sec intros. Thanks!
Naaaah... Don't cave to impatient people... (Your craft is sound). I liked the intro as it helps me mentally pull focus on the subject we are dealing with. It's like you have been outside in the sun, and it takes your eyes a good 45 seconds to adjust to a dark space. Similarly with the topic in hand, most people transitioning to this video are having to deal with the flotsam and jetsam of everyday life... So I find the introduction helpful to change "Metal gears" and be able to visualize and in a sense try to intuitively feel or wrap one's head around the vastness and truly epic naure of the topics we are dealing with. It's all good ! :-)
+Extra Dimension That is a good point
It used to be smaller, but for some unexplained reason it began to expand.
Let's face it.goes on forever
If the universe has boundaries, it's said that we can never reach the border because it's constantly moving away from us. However, who's to say our Galaxy isn't close to the border of the universe? Still too far to detect it, but still right on the edge, moving along the border as the universe expands.
We know that we are at the CENTER of the OBSERVABLE Universe by definition. The Observable Universe is the maximum distance than we can see when we look out into space. Since we can see the same distance in all directions, then we are at the center of the Observable Universe. The radius of the Observable Universe is defined by the Particle Horizon, which is calculated to be at a distance from the earth of over 46 Billion Light-Years in all directions.
So we're over 46 Billion Light-Years from the edge of the Observable Universe in any direction we look, and we know that the Total Universe extends beyond that......probably FAR beyond that. So even if there is a boundary to the Total Universe, we know that we are very far away from it....at least over 46 Billion Light-Years. A "Veritasium" video on TH-cam discusses the Observable Universe and the Particle horizon. It's titled: "Misconceptions About the Big Bang,"
One thing I often wonder is if the Universe is finite and has an edge, then what would it be like for a civilisation living in a galaxy on the edge, in one direction there would be nothing and in the other there would be everything. Very cool
U need to go to Arby's they have new stuff on menu ok?
Rasverix Xyleighraq there is no end to the universe just like you can count for ever ! There is no edge to anything ,it goes ever increasingly smaller and same bigger !
Rasverix Xyleighraq , I often wonder what the night sky would look like if we were in a different location within our galaxy especially closer to nebula, would they have been part of mythology? The Titans perhaps? Being at the edge of the universe would be a natural variation on that theme.
Duuuuude
Rasverix Xyleighraq there is no such thing as nothing
Universe, Megaverse, Ultraverse, Omniverse, Zverse...just joshing..this very beautiful.
The Universe has a membrane at the edge and on the membrane, written repeatedly in a plethora of languages is the legend, "Slow, Spaced Out Hippies Ahead!"
Smoke another joint.
The Truman Show, all the way out. Something beyond the transfinite boundary is replaying our universe’s recorded spacetime tape. Heck for all we know, it might even be a malicious extra-dimensional child.
That's right. We are living inside some kid's Science Fair experiment.
I have a question, where is the universe located?
Mnakekeli Ngcamphalala I don't quite understand what you mean by that, but if i somehow understand what you've asked, "the universe isn't located anywhere, it's just there."
Yusuf Omar But where is "just there" located?
Mnakekeli Ngcamphalala
That question doesn't seem quite logical to ask as the universe doesn't have any other points of reference we could use, *that's detectable*, that we could compare *it* to. So far as we know, its just there, expanding ..
If you were to ask, *" Where our star & its surrounding planets were located within our galaxy "* or *" Where the nearest star system to our solar system is located "*, then yes, those are questions we could correctly answer as scientists have studied & calculated the distances to acquire the answers to those questions.
& if you're curious to know what the answers are, to the above questions;
- Our solar system is located in the outer reaches of the *Milky Way Galaxy, & is a spiral galaxy.
- *Alpha Centurion* is the closest star system to our solar system, ( its *4.37 light years* away from us ).
:)
Mnakekeli Ngcamphalala The universe is located everywhere.
Mnakekeli Ngcamphalala To ask that you have to presuppose that our universe has boundaries and out of the boundaries there are more universes. As we don't know if our universe is infinite or not and we don't know if there any other universes out there, your answer cannot be answered! Sorry!
E=MC2 also says that space, time, and energy are finite. If the universe has a beginning then it has an end. Everything loses energy with the passing of time. Then energy will end and the expansion of the universe will reverse into shrinking and it may be faster or earlier than we ever imagined.
The universe is just a piece of candy lying on the ground in a park.
We are so damn small that we will never ever comprehend this...
this video is roller coaster of emotions !
The more I learn about the universe, the less tangible it gets. Space and time linked, third dimension is an illusion, space is a hologram, energy out of nothing, virtual particles, time is an illusion, etc... I did not know that a year ago... If this goes on I think in a few years time, I will learn that my whole existence is an illusion created by my own illusive brain or something?

Ronald de Rooij Good question, when I read idiotic posts like yours, I come to the conclusion with evidence that this man has written an idiotic comment. Therefore, the only plausable reply, is to ask the question "are you an idiot". If you dont want to be called an idiot, then dont write idiotic comments, its that simple.
24414330 I could not care less to be called an idiot by people like you, haha. I think you really are good in projections. Idiot!

Atomic Vapor That's a good sign
These videos by Deep Astronomy are really well done and excellent explanations of so much of what we know, and what we're still learning, about the Universe we inhabit. Wonderful stuff!
Nice.
If our Galaxy was the size of a Neutrino, the size of the observable universe would be about the size of a Hydrogen Atom. All things being relative we should be studying and spending more on the Sub-Atomic "world". We like to think BIG but thinking small sort of frightens most of us...
I liked the ending saying how we used to think the galaxy was an island and now that’s how we feel about the univers
Asking what's beyond the universe is like asking what's north of the north pole
So if it's infinite with no boundaries then how did the medium of an infinite universe suddenly come into being and what existed before it came in to being, and if it was nothing then then what defines nothing and how could the state of nothing become a state of something, and has the state of nothing existed for an infinite amount of time beforehand and how and ughh wtf
You're off the edge of the map, Mr. Harrison! Here be monsters!
toatahu2003 fucking awesome reference
Because the universe complete with space, time, energy and laws is thought by God. There can be nothing material where there is no space. Our reality has been carefully thought so that everything fits. And we don't even know it. He has still more computing capabilities. Infinite.
Adam Harrison I think the universe is infinite and always existed, but is also always undergoing change, with the rate of change itself varying. However, there is underlying structure to the universe which is not entirely entropic as "scientists" would have everyone believe. This is easily seen in spiral galaxies and the spirograph pattern of magnetic fields, etc.
Adam Harrison something can’t come from nothing
Everything came from the unmanifested absolute which is perfect
Those in the know are referring to this thing when they say God
What an interesting question! I never thought of that before!! Thanks.
..This is pure Philosophy..
When you throw stones in the water what is the water expanding into?
From nothing expanding intro nothingness.
Joshua Nicholls yes we kno ur gay but what else are u trying to tell us
This video really makes you think!!! Should people be making shorter intros :P
Simple, either an expanding universe into infinity, or an expanding universe which will then contract, resulting in a crunch leading to another big bang. Not sure how you prove either hypothesis, but go for it, and I wish you luck.
when there are no answers we simply give up and use the god did it theory, fortunatly not all of us are quiters and seek the answers through study and observation, lets hope we never stop learning, and if there is a god he shouldn't judge us for being courious.
I agree
I didn't watch the full video. Can you tell what are you really curious of?
You are talking about the Gap of the Gods.
God made us curious and hungry for meaning and truth. He loves His creation. Stay curious folks.
Video starts at 0:45
Good looking out bruh
This should be pinned
Maybe we are looking at this at the wrong angle or perspective. I imagine the universe as a 4th dimensional balloon.Imagine you are inflating a 3D balloon then 2D creaturs thrive on it. They will think its infinite because there is no edge and they think that their universe started from a "point" but the truth is, it started everywhere. As you indlate the balloon, every part of it expands. So maybe our universe is like that. Expanding into a 4-Dimensional space.
TheOmnipotence 👍
Finite but infinite, exactly. I thought of that also.
I love your theory
pretty popular theory in relativity. The universe is either flat or a weird 4 dimensional thing
But that begs the question, what is the 4 Dimensional space and how did it come into being
Universe is infite and will continue to expand forever.
Speculatively it could be expanding into the substrate of a multiverse.
Cooks With Spoons shut up idiot
Why should he? He could be correct. No one really knows.
what if our universe has always been expanding and there were infinite amount of big bangs that exploded and expanded the galaxies before ours. If that is true wouldn’t it make sense if the civilizations from early big bangs 1. gotten so advance that we are not worth visiting. 2. Extinct.
I love the use of the word 'creation' in this.
@4:10 " if that is true however, then the boundary is so far away that we cannot see it, and it can therefore never ever affect us."
Right. Because things that we cannot see never ever affect us. Like germs and radiation. Good logic there
We'll never know.
There are no exact answers, the universe appears to be like a balloon that continues to expand.
What is the expanding balloon expanding into? Nothing, it creates it's own space.
If there is an end, then logically there must be something outside of that.
Ya, kinda like a balloon but whats inflating that balloon? its more of that space that you just called "nothing". Its not "nothing" it may be a NO THING but not nothing, its the smallest of the smallest of the small and everything in the universe is in it right now.
what is the space between electrons or quarks or anything in that scale? It's not air of course, it's not gas (we are on a far lower scale) what is it? It is empty and consists of nothing yet it provides some distance in space...Maybe I am just ignorant...
The latest theory is everything is a tiny string of energy. So you don`t think about space. The universe is and we are just uneven strings, with one end or other being a bit more energetic than the other. So when we try to detect atomic particles, all we are doing is detecting the heavier bit. And to me it kinda explains quantum theory, if these heavier bits on the string move around.
easyeagle2
thank you for the reply, but the question then just changes to: what is between the tiny strings? :D I am guessing energy and it is made out of some tiny tiny particles, then I ask what is between those and blah blah...Do we even need to know? :)
I thought the strings created the grid of the universe, sort of like quantum foam in Einstein's space-time theory.
String theory is (currently) physically untestable and entirely theoretical, constructed from mathematical models and proofs. But I think Ludak was asking "what is space on small scales?" Well, we don't know. It's energy is greater than zero everywhere and it's expanding.
SpaceTimeMachine Another theory suggests it is dark energy
Ninja was the one who brought me here, IAM now an Intellectual
Mr. Darnell, you're an amazing narrator!
Very reminiscent of Carl Sagan!
Question: I've heard some say "new" space time is being created, and that causes the expansion. But ive also heard it said that time-space is simply being stretched....which one is it?
I think it's more accurate to say the former. New spacetime is created, but the question is, where does it come from? The research into dark energy hopes to settle that issue. Because the universe is accelerating as it expands, there is a force associated with that expansion. Forces need energy, so what is it? And that's a burning question in cosmology right now.
I see. Thank you for clearing that up for me. I love your channel. And if you dont mind me saying so, its one of my favorite places to go after I smoke a joint. Cheers!
This is good stuff, that goes with good stuff....
both, the idea around dark energy is that space itself is growing from the inside, so space isn't exactly stretching but new space is coming into existence everywhere, so in between two bodies more space is coming into existence, its just too small to see on a small scale like inside of a galaxy, it's only relevant across billions of light-years. Its why the universe in a way has no outer edge because the expansion of space moves at a rate faster then light speed could travel so nothing could ever reach the edge.
Dark Energy, if it in fact exists in the way we think it does, is raw creation. Where it is not, there is nothing. Where it is, there can be something. Theoretically, Dark Energy's expansion is defining a finite space (our universe) within a blind infinity. Though, who are we to say that there aren't other pockets of dark energy doing the same thing, I.E. _other universes_ which may eventually contact and connect with our own.
The universe expands to give stars a place to live.
It may be that the universe is not 'expanding' into anything, but rather 'thickening out': what began as 'empty space' becomes progressively more densely filled with light & gravity, and it thus takes longer to get from A to B (in both terms of time and space, the continuum being space-time after all). From the perspective of those within 'the universe' it is expanding; from the perspective of those at the very (Escher-like) edge of the universe, they are simply taking longer (and experiencing more) to get anywhere.
The universe is expanding into itself.
Matter has no beginning and no end !
I believe what you mean is "Given enough time all matter changes (sometimes with explosions) through space with gravity". I agree with you that matter didn't just come into being something from nothing.
So what would astronomers in the most distant galaxies see if they look in all directions ?
They would see basically the same sort of things we are. A never repeating pattern of galaxies, each becoming bluer and younger and smaller as duo look further out, then would see the point the universe reionized in the cosmic microwave background.
This Universe is not only larger than we thought, it's larger than we can think!
In the video he said that if there is a boundary we can never see it because the universe is expanding. I've got a fair understanding of the expansion of the universe concept (I couldn't follow the math to save my life but I think I understand the concept fairly well) and of course looking from earth we could never see the boundary if there is one but if someday we derived a technology to warp space to travel faster then light or create wormholes and teleport then what is stopping us from seeing the boundary?
hmmmmm what if the universe is super damn vast so that even ftl and wormholes wouldn't get us there faster than the universe is expanding? like, we'd always be behind. or mebbe the universe is inherently unstable near the boundaries? eh who knows
Actually, black wholes and white wholes with their wormhole link will disintegrate you.
renge9909
What if simply going is what expands it? It would be like chasing that first heroin high.
If you imply a boundary for our universe, which is everything there is, then by definition there has to be something "on the other side" of that boundary....which would be everything that isn't. If you can make sense of that, then please inform us.
Alan Hill Well of course I have no idea what the boundary would be like or what the other side would be like but in the video he's saying that if there is a boundary that we can never see it because of the expansion. He doesn't say we can never see it because the other side is the opposite of something he says that we can't see it simply because we can't get to it. Did I misunderstand that part?
Time is the barrier which keeps us imprisoned on this planet...when we break through the perception of finite, linear time, (which is an illusion and thus CAN be broken through) we become infinite beings with multidimensional knowledge as a natural consequence of that. That is what the mystics were alluding to and that is why the deepest Kabbalah from two thousand years ago was able to outline principles that the new physics is only now beginning to "discover". It is not a matter of "understanding" intellectually through equations, it is a matter of us realising, experiencing and becoming that truth, which we come to by dissolving the illusion of our perception which keeps the truth hidden from our eyes. Many people at this time are beginning to wake up. This is the next stage in our evolution, much needed, when you look at the mess we have made of this planet, but forgivable as you would forgive a toddler for making a mess of its playroom. Our race has merely been in its infancy for the most part of commonly remembered history, though there have always been those souls who have seen the truth and tried to point the way.
The barrier IS our temporal illusion. Our flawed perceptions are thoughts and concepts about reality, not reality itself. Our consciousness is non physical, and thus if we can ascend above our normal perception, we can connect with the limitless of the quantum field. People are stuck in varying mind patterns, according to their belief system and conditioning. Youa lways find that the achievers in life are the ones who dare to break through their own perceived limits, but that breaking down goes on a long, long way... Our consciousness makes up the hologramic reality we see around us, affecting every atom and every particle, and by changing our consciousness, we can change ourselves and our life circumstances for the better. If you are going to live in an illusion, you might as well make it a good one!
Meta-physical spiritualistic woo.

"The fabric of space and time is expanding"
This is why I (being polite) call these people "babbling idiots"
*First-* Time doesn't exist, it's merely a measurement tool created by humans to measure how long it takes for a particle to move from point *A* to point *B* and,
*Second-* If space was "expanding" the most basic logic tells you that we wouldn't be able to realize it because *EVERYTHING* would be expanding at the exact same rate. Hence the solar system would be expanding, the earth (and everything in it) would be expanding, WE would be expanding, and of course our measurements devices would be "expanding" as well, *AND* with it the measures themselves.
just because you dont understand something, dosent mean that the person explaining it is an idiot. "first-" time does exist, and its not a "measurement tool" created by humans.. its a word created by humans to describe something (like everyother word). www.oxforddictionaries.com/definition/english/time
when people talk about the "fabric of space and time" they are referring to this: en.wikipedia.org/wiki/Spacetime
Merlith Gero
You are just regurgitating like a parrot what these *babbling idiots* CLAIM. Yes, it's a word created by humans to describe something, indeed. It describes *how long it takes for a particle to move from point A to point B* But, If like you say, time "does exist" = *prove it*
SHOW us "time"
As for "what they are "referring to" when talking about this, the entire thing is based on the *presumption* that time "does exist"
So if you are gonna refute what I said, do so explicitly. Show us how we would be able to perceive the "expansion of space" when ALL of space (that is *the entire Universe and everything in it*) expands at the exact same rate which would OBVIOUSLY include the space contained in every single atom causing *EVERYTHING THERE IS* to remain at the exact same size/distance in relation to everything else.
Let's see your "understanding"
***** Time was not invented by man. The MEASUREMENT of time was invented by man. Just like how we didn't invent a meter or a kilometer. These things have always existed, we just found a way to measure them. Run along now.
OfArgento The measurement created by man measures how long it takes for particles to move from point A to point B. That's what it measures. It doesn't measures "time" simply because time doesn't exist. But, (if like the previous regurgitator) you pretend that "it does" you are welcome to *prove it* as well. SHOW us "time" wise one...
***** my gawd. you are an idiot.. i even linked you the definiton of the word and youre still incapeable to understand basic logic. its NOT a measurement tool. the fact that everything age, that a clock ticks, that something rust or rot, creatures evolve, planet circling around the sun.. ALL of these are examples of time. its just a bloddy word to explain the indefinite continued progress of existence and events in the past, present, and future regarded as a whole. if you cant grasp something as simple as this, then you clearly lack the intelligence to understand astronomy, so i advice you to watch something else.
how do we know the universe is expanding? well, the answer is luaghably simple.. because through years of analyzing and calculations, we can see that things are moving further away from each other. why is this difficult to understand?

the only "babbling idiot" here, is you.
This is the best video that I have listened to so far, that explains the universe. It is simple to the point! Thanks. 👍
I really wish I knew the answers to some of these questions! to the point where it angers me not knowing!! when will we know..
The universe blows my mind, we know nothing
Yeah. I’m just thinking about removing my living room carpet, and replacing it with tile.
What if there’s another reality with other people in other places that are thinking the same things we are...
K so I’m scared
Read some more science fiction books. Can you read?
Maybe we are like nanoscopic cells, thinking that we are a extraordinary intelligent species and amazed by how "huge" the universe is, while we, along with our galaxy are unimaginably "small."
Why would that scare you?
In this immense Universe it is almost guaranteed that there are other beings, somewhere, wondering the same thing.
Nothing to be scared about!
For every action there is an equal and opposite reaction. Something has to be getting smaller somewhere....
3:07 KSP vets know all too well what that music means.
"I actually got this flying bundle of fuel and scrap metal into space!"
jup, haha.
The minute I heard that music I'm just lie "ayyyyyyyyy"
Left out one important fact: the expansion is so fast, we may never see other galaxies in the future and our future generations may never know there are other galaxies in the universe, or even there's a universe. We are alone. Are we an anomaly, or the start of something? We may never know and our curious and limited minds must accept that's a fact we must live with.
****random thought*****
when we are on earth we look outside this sphere and see stars and planets and galaxies ..... what if the observable universe is just another sphere that we are in that we could escape ..... and we could get outside of it and look down onto our universe ..... and see other universes existing inside another sphere!!!!! We may never know just how small we are in the grand design!!!! I'm not offering any science here or theology just a random thought based on pure imagination!!!!!
Magic, thank you.
Yup, I knew it... we live in a universe.
It may not be so mush that the Galaxies are expanding out into new space but that new space is getting in between galaxies. OR. its not so much that galaxies are moving away from each other but more space is moving in between them.
The spooky music, that distracts from the narrator, tells me right away that this video is entertainment; not educational.
we live in a simulated universe... everbody knows that instinctively..
When the big bang happened, what did it explode into?
This video leaves more questions than answers.
is the universe flat?
... das weiss nur Gott mein Freund .
***** In other words, no one knows? Is that what you are saying? But surely, one can find out. Isn't that what science and cosmology is about, finding how the world of nature works? So why do you want t give up on it?
Gunter Raffel It was not meant to be a scientific answer. Has for science, they cannot know what is not observable. We would need to step outside the universe to see. There are things science will never be able to answer. Things like; Why anything instead of nothing?
hellavadeal ok, that makes perfect sense. It would be difficult if not impossible to describe a accurately describe the true nature of a bottle of Coca Cola if one has lived only inside it. An exterior viewpoint would be required. Science does not dare to venture that far, but why should that be impossible?
Gunter Raffel I should have define what imposable means i guess. "Until we find some way to do it", might have been more appropriate. Thanks.
