How large is the universe? Where does it begin and end? And how does it expand? These are some of the biggest questions of astronomy. And while humanity is so small that we may never be able to fully understand the true scale of the universe, advancements in technology are helping us to look ever-deeper into the wilds of our existence- towards the edge of our observable universe, known as the Cosmic Horizon. Today, we will analyse the universe, its laws, and its awe-inspiring scale.

I think there is truth to this, however I believe in the other side of an argument I have too. I believe the vast unknown of crazy holy hell knowledge and stuff the universe contains, drive some people insane. Hence why some just choose to completely ignore it. Or turn a blind eye to the facts the universe contains. The universe is humanity's most humbling subject.

I think the saddest part about the universe is how it's actively isolating us from everything else due to its rapid expansion. It's fascinating that the very process of creating more and more gives us less and less to observe
The expanding state of the universe as well as a few other implications makes me wonder if we will actually discover/master inter-dimensional travel faster than we master traveling through space. Like if traveling between dimensional strata is majorly a case of energy production then that would always be easier than creating and maintaining a space faring vessel and its crew on journeys that could last upwards of 100 years.
@@GiraffeCrabinter-dimensional... As a 3D human, to go into 4D is effectively time-travel.
@@Niyto it very well might be time travel. But I think it will be easier to work out how to time travel or any other dimensional hopping than it would be to get a crew of 50 in a ship through the kuiper belt or past the oort cloud. The logistics of such a feat are mind boggling. But if interdimensional travel is more of an issue with energy production then it would be theoretically easier than space travel.
Not only less to observe. Even if we invent near light speed travel, most of the universe is already beyond our reach, and even more slips away each day that passes. I’m generally positive about human progress and the idea that we will one day move beyond earth, but thinking about the challenges I sometimes doubt we’ll ever go beyond the solar system.
@@jezna1785we’re too busy chopping off our genitals and psychologically torturing our own species to become a space faring species. Besides the moment we make contact with an alien race it’s only a matter of time before we get into a war with them.
This has been one of the best videos about astronomy I've ever seen, it includes everything I've seen in every other video and the relation between it in a single video and is put together so elegantly and makes understanding it or finding the relation between different things I've known very easy and admirable . Thank you ❤
This video was made by AI, don't trust it and don't be inspired by it. There are a lot of creators of actual videos about this subject out there
Is gravity faster than the speed of light?

The irony
Mooddd
Yeah that's a fail
Have you seen the video where they use marbles and beach balls to show the relative scale of the sun and solar system? They have to drive across two states to place the marker for next star system I believe
So close, but yet, so far...
You’re really good at getting just the right mix of casual depth and more advanced concepts into your videos. Gives the viewer room to research more into a topic, but also doesn’t lock them away behind a bit too much detail, or not enough to be interesting.

Same...always
No matter how many times I view pictures showing “Hubble Deep-Field or Hubble Ultra Deep-Field” my mind is always melted by how impressive it truly is that those light-points in the photographs are entire galaxies!!
It’s mind boggling that all those light points look so close together….yet they are so far apart from each other that most people can’t understand the distance….even when told using the the numbers we’ve been using our whole lives. What gets me thinking a lot is the fact that we can see things that are impossible to actually get to…think about that!?!?
I love the shot on the deep field south showing the quasar…phenomenal that light from such a distant point to us in space and time can flare out so brazenly like that…beautiful and mind boggling.
@Ryan Roberts preach ✊
@Ryan Roberts Oh, but we HAVE seen farther than that! In fact, in the Hubble eXtreme Deep Field (XDF) we have discovered a galaxy 10.4 billion light years away! James Webb ST is going to be able to document galaxies even further than that through the opaque gas of the early universe thanks to its vast capabilities to photograph in infrared!
@Ryan Roberts You are joking? Or can you not see objects that existed before you were born? Lol.
This channel is the best I have seen so far amongst all the ones that explain the concepts of the universe and space/time. The reason I like it the most is because the explanation is simple and clear, and the focus is on helping everybody understand the mysteries of the universe. What I particularly like about this channel is that it is focused on the facts supported by research, and there is no attempt to intersperse the explanation with needless, unnecessary music and over-dramatizing. In some channels, the loud music is sometimes so distracting that it actually takes away from the focus on the facts of the science. And I say this despite being an English Literature graduate, with no background in Science. If I could understand and appreciate it, I am sure anybody can. Thank you for this excellent channel and narration!

It's so beatiful, and then saddening that humans as a species will never get closer, or learn more information than we can already get from light, as they're all moving away from us from cosmic expansion faster than we could ever race to catch up.

The fact people are awarded “MISS UNIVERSE” without having any idea of the cosmic scale.

Whenever I catch myself lying awake overthinking, I just imagine myself being on a rock in space. Then my view pans to an external observer of Earth, then to it's Solar System. The scale goes on until my problems seem pointless. It may sound negative to some but when it works I can say, even if only for a moment... I find peace.

Wow that’s more than two football fields
And according to this video, at least _250 times_ more!
@@patricknelson That seems like a little much... I’m gonna go with 249
You actually got me interested in how many football fields and so I did the math; The universe is 46 and a half billion light-years in diameter. 46.5 billion light-years is 481,106,700,541,000,000,064,640,024 yards. An average football field is around 100 yards. 481,106,700,541,000,000,064,640,024 divided by 100 is 4,811,067,000,000,000,000,768,296. So, 4,811,067,000,000,000,000,768,296 football fields would fit the entire (observable) universe. Mindblowing.
@DECLAN DOUGAN Ah. You are correct. In that case, 9,622,134,000,000,000,000,536,592 football fields would fit the diameter of the universe.

One thing I've been wondering is: If we know that spacetime can be warped by things like high gravitational fields, how do we know how far away anything truly is if there might be a warping of spacetime between us and it? So the observed celestial body may be closer or further away than we perceived. How do we know that both space and time act the same way throughout the universe?
We dont. Its just an estimate, like all else.

Indeed, but luckily we'll all be long gone by the time this happens
It's speculation, there is evidence that the expansion of the universe changed in the past so there is no way for us to know how it will behave in the future or what other fundamental mechanisms from physics may kick in. Personally I believe something completely unpredictable will happen that will make the universe as interesting of a place as it ever was.
@@Leandro-bj6jh who knows? Perhaps more 'big bangs' might take place within the empty, dark spaces during infinite expansion.
@@Leandro-bj6jh Yeah, there is some interesting and really awesome theories out there that I love. There is one that says that our big bang's singularity was a previous eon's 'heat death'ed' expanded universe which achieved entropy, which then was rescaled - That at some point in the distant future the universe will actually forget it's time and scale when it reaches entropy and that it could create a new big bang as when the scale is forgotten then our entire dead expanded universe could actually be a singularity itself and fuel the next one. It wouldn't be a big crunch, it would be a rescale that would bring immense heat in all things which turned cold in entropy and that this cycle of eons would be infinite.
Anyone else ever miss people they've lost when watching videos like these? Idk why.. the cosmic scale stuff gets me thinking.. they must still be out there.. somewhere.. its like I can feel it.. sometimes.
OMG.. I've known what red shift is for years and thought I could explain it.. but the animation you make is by far the best explanation I've ever seen. I think I even understand a little bit better now.

thats exactly why, we fight each other other because people want it all
HUGS! :)
Religion.... man made.
an excellent question, the answer to which will be provided either by evolution weeding out that combative trait, or our disappearance from the face of the planet
Why not fight? If violence and exterminating other people gives you pleasure, what do you owe any other being or creature? You have a spec of time before the universe literally comes to an end at the moment death takes you. You won't know if you lived 2 years or 80 years, so what's the difference? You won't have a spec of knowledge, memory, or recognition about what you did, learned, loved, created, or accomplished. So what's the difference? Would you pay for four years of college if upon graduation, the entire four years was utterly wiped from your memory so that you had no idea you even did it, and anything you learned was wiped from your brain, and your diploma was wiped from existence? Well, that's life. And does it matter how long you live if you won't even know it ever happened anyway? So do whatever you want. There is literally no consequences. And we aren't all we have, because we have nothing. You won't even know that anyone lived or whether anyone cared for you or you cared for them the second you close your eyes in death. Or the alternative answer to your question would simply be, because mankind is broken and have fallen short of the glory of God as we use the free will he gave us to reject his command to love one another. Along with that goes the good news that he provided a remedy, and that what we do does matter, and does live on beyond this life.
Astonishing amount of work put into this!
Your documentarian skill has grown so much. Well done. This one particularly has been my favorite for the passed few years. Thanks SEA.
A special emotion pops out whenever I think of the universe. An emotion that encompasses pride, optimism, humbleness and shivers. I feel as if I am helpless and all I can do is bow down to its almighty greatness. And believe me or not I sometimes almost cry when I try to realize how graceful it is. Living in such a magical realm is more than enough for me. My only God is the cosmos itself and I will be grateful today and tomorrow and for all eternity for its existence, even after mine has come to an end. Thank you for the video. I appreciate every content maker who does these kind of videos.

Sometimes it upsets me that we are smart enough to kinda understand all off this, But at the same time we are so tiny and so young that we cant explore non of it.
Same. I felt this 💔
Settling in for bed, and I'm not sure why I need these videos to sleep 🤦🏽♀️😅
Perfectly done brother! You been puttin a lot in this!
"Every nanometer of space expanded 10 light years in a fraction of a second." aaaaand my brains broke.
it breaks all known laws of physics, only proving that when enough matter is compressed or enough energy is generated that physics as we know it breaks down
That means in 60 seconds, a minute passed in africa ok sorry, that just means in just a second, our space can get bigger, in size of 10 light years.... in just a second our space can get that big... you know what my brain broke too.
@@myra961 not even a second it’s like millionths of a second...I guess that doesn’t make much difference compared to 100’s of billions of years 😂 but still wtf! This shit just doesn’t make sense why do I have to die before we figure this out !!!

You have the most amazing channel I have ever come across and THANK YOU, wow...
Another awesome video, very well done. I was so engrossed by the ending that I literally felt a sinking feeling at how it will all (in theory) turn out. Then I realized that I won’t be around for it.
I've watched the entire "Ultimate Space Playlist!", and I gotta say, you guys have drastically improved your videos from 2018 to 2021. A few things I noticed that improved were: you spoke more slowly, and the images/videos you use were more varied. Great work SEA, I love your vids! Keep it up. (please)
My brain just crashes whenever I try to comprehend any of this.
Our brains just aren’t evolved for the true scale of infinity. Nonetheless, our curiosity drive only gets stronger
Even at the first 5 seconds the brain goes OK
Have you tried turning it off and on again?
It's all a matter of scale. Compared to the size of our huge but cosmically tiny Earth one human individual is incredibly small. Compared to an ant a human is an incomprehensible giant. Compared to an ant a water molecule is incomprehensibly small. An atom is smaller, a proton is smaller, atomic particles are smaller. The universe is almost infinite in both directions it seems. I find it amazing enough that the sun could contain 1 million Earths.

We need an updated video on the Hubble Deep Field section now that JWT is live! 🙂 Enjoyed the video - thanks for the hard work.
Every nanometer of space was stretched to over 10 lightyears. Under the fraction of a second. [Screams in Brain Breaking Down]
Dude, I really wanna meet an alien on this lifetime. I cannot imagine how different their mind, culture might be. This is my biggest dream
I once saw one walking across a road and it disappeared before my very eyes. This was nearly 25 years ago in a village of Central America.
They may not even have "mind" or "culture"
Great dream to have, to be bold enough to act on it however
I’m not sure I would want to meet another alien. The example is ourselves as we look to colonise other worlds but do not think that maybe just maybe it may not be our world to colonise should we find another world that is as hospitable as ours. Also we as a species kill other animals for food and keep animals captive in zoos etc. Now having said all that what if another alien considered us as food or wanted to put us in a zoo? It’s a thought as natures law is eat or be eaten and that law will probably be for space too. Thankfully space is vast so I find that vastness a safe space for our own protection in all honesty.
Aliens or if there is intelligent life look at us humans as we would look at ants , insignificant and primitive hence why there is no reason for them to “meet” with us
The content was simplified to a degree that I finally understand so many of those concepts I've been only hearing about for years. Seriously good work. Mind blown
He is wrong about the dark ending....it will become the new beginning. In the beginning the universe was formless and empty, darkness was over the surface of the deep, and the Spirit of God said, "Let there be light," and there was light ( the Big Bang). Yippee Yahoo here we go again! Prove me wrong 🤩
@@mitchgodwin If you make a claim like you have done, the onus is on you to prove the claim right not for people to prove you wrong. I could just say to you, the Universe started one second ago and all the thoughts you have in your head were put there. Prove me wrong. In other words, stop being silly.

To learn theorys in small digestible videos try pbs space time it takes something like the holographic principle and explains it w graphics in a relatively short video
A great find of a channel, which deserves far more subscribers due to its excellent production and narration
absolutely amazing and terrifying all at once, glad youtube recommended this 2 years after release
I surely didn't want this to end. I wish it kept going. Beautifully made. I'm out of words.
I’m 22 and I’ve been using YT in my own since I was 6. I’m glad to say this is the best video I’ve ever seen in my entire life. Thank you so much.

With so many stars with planets orbiting them at similar distances from their suns as we do, it’s impossible that life doesn’t exist elsewhere.

even if the universe has a boundary, humans would still ask what's beyond the boundary.
My sentiments exactly. Just what IS beyond the farthest galaxies? Limitlessness? We can't comprehend that, so what is there must "infinity," or better yet, eternity (i.e., timelessness).
@@RadarRecon Exactly. What is beyond the universe's expansion? Nothingness? A larger universe? We will probably never know.
@1 New Notification Prove it
@1 New Notification Don't kid with me, you have nothing to teach me, nobody can prove the existence of another Universe. Period.
@1 New Notification You don't have how and nobody is close to it as you try to say. String theory is not science and my guess is that it will never be.
It's kind of ironic -- when we first studied astronomy we thought our galaxy was all that there was. Several billion years from now after the local merger and the last of the other galaxies move beyond the particle horizon. any new civilizations that arise and who reach our tech level will think the same thing. But unlike us, they will never be able to know any better. I guess we are pretty lucky that we live in the universe when it is so young :)
Just imagine that, all there is is just A galaxy, will that feel lonelier or easier to grasp?
We are already thinking that about our universe. It is assumed that our universe is all that there is, but maybe in the earlier or later times other universes were or will be detectable. The amount of potential discoveries that we are blind to must be unimaginably greater than what we already know.
@@ChinnuWoW our universe could be much larger but another universe would essentially be another dimension unknowable outside of space time
The universe might've started to collapse in on itself by then...
Likely a super advanced civilization during this time could guess that other galaxies do exist. They would detect the expansion of the universe and therefore could theorize that there were galaxies close to them in the past. They could never see them or verify it though.
I think you are right. Life is everywhere. Thank you for your videos. Love them.
